I have a UITableViewCell with two UILabels and a UISwitch. The labels are multilined and placed on top of each other. The UISwitch is centred vertically. When I turn off the switch I hide one of the labels and the height of the row changes. This causes the switch to jump though I call:
[self.tableView reloadRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
Here is my tableviewcell class implementation:
- (void)setBounds:(CGRect)bounds
{
[super setBounds:bounds];
self.contentView.frame = self.bounds;
}
- (void)setUpView{
self.numberLabel.text = [NSString stringWithFormat:#"Quote number %ld", [self.cellData[#"rowNumber"] integerValue]];
[self.controlSwitch setOn:[self.cellData[#"checked"] boolValue]];
[UIView animateWithDuration:0.5 animations:^{
if ([self.controlSwitch isOn]) {
self.quoteLabel.text = self.cellData[#"quote"];
self.quoteLabel.hidden = NO;
self.bottomConst.constant = 10;
}else{
self.quoteLabel.text = #"";
self.quoteLabel.hidden = YES;
self.bottomConst.constant = 0;
}
}];
}
- (void)layoutSubviews
{
[super layoutSubviews];
self.selectionStyle = UITableViewCellSelectionStyleNone;
[self.contentView updateConstraintsIfNeeded];
[self.contentView layoutIfNeeded];
self.numberLabel.preferredMaxLayoutWidth = CGRectGetWidth(self.numberLabel.frame);
self.quoteLabel.preferredMaxLayoutWidth = CGRectGetWidth(self.quoteLabel.frame);
}
- (IBAction)removeQuote:(id)sender {
[self.delegate updateCell:self];
}
The constraint settings on the UITableViewCell looks like this.
When the switch is turned on, I'm simply unhide the Quote label and set the text.
Here is the link on how it looks like. Is this the default behavior or is there a way I can control the movement of the switch when the row animates?
Try this:
...
[self.contentView updateConstraintsIfNeeded];
[UIView beginAnimations:nil context:nil];
[self.contentView layoutIfNeeded];
[UIView commitAnimations];

My app currently has a search bar and generates a holder view of results dropping down from the search bar. However, the ResultContainerView is behind my other Views. I am wondering how to bring that search bar container view to the top of the UIView hierarchy. I tried using [super bringSubviewToFront:_searchResultsHolderView];
but that did not work. Here is my method for when the searchbar is tapped.
- (void)_expandSearchResults
{
CCLogVerbose (#"");
_searchResultsHolderView.alpha = 0.0;
_searchResultsHolderView.hidden = NO;
[_searchResultsHolderView setFrameHeight:10];
[UIView beginAnimations:#"expandSearchResults" context:nil];
[UIView setAnimationDuration:kAnimationDuration_SearchResults];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector (searchAnimationDidStop:finished:context:)];
_searchResultsHolderView.alpha = 1.0;
[_searchResultsHolderView setFrameHeight:_searchResultsHt];
[super bringSubviewToFront:_searchResultsHolderView];
[UIView commitAnimations]; // start animation
}
And this is my reloadData method:
- (void)_reloadSearchResults:(NSString *)searchS
{
CCLogVerbose (#"");
if ([searchS length] == 0) {
_searchResults = nil;
[_searchResultsTableView reloadData];
return;
}
NSAssert (self.patientService != nil, #"The Patient Service is invalid");
[self.patientService searchPatients:searchS
expandType:AllPatientExpansions
success:^(NSArray *list) {
_searchResults = list;
[_searchResultsTableView reloadData];
}
failure:^(NSError *error) {
CCLogDebug (#"Failed: %#", error);
}];
}
[self.superview bringSubviewToFront:self];
[self bringSubviewToFront:_searchResultsHolderView];
First you need to bring self to the top of the stack. After that you can call bringSubViewToFront and bring your _searchResultsHolderView to the front.
Edit: I awarded the bounty to john since he put a lot of effort into his answer, and would get it anyways, but there's still no working solution. I am still looking for an answer, if someone knows how to do this it'd be greatly appreciated.
I want to add a "maximize" button to my app that hides the navigation and tab bar. The navbar and tabbar should slide in/out smoothly, and the inner/content view should also expand and shrink at the same rate as the navbar and tabbar.
I used [self.navigationController setNavigationBarHidden: YES/NO animated: YES]; for the navbar and found this thread How to hide uitabbarcontroller for hiding the tabbar.
UITabBar class extension:
- (void) setTabBarHidden:(BOOL)hidden animated:(BOOL)animated {
CGRect screenRect = [[UIScreen mainScreen] bounds];
float screenHeight = screenRect.size.height;
if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation)) {
screenHeight = screenRect.size.width;
}
if (!hidden) {
screenHeight -= self.tabBar.frame.size.height;
}
[UIView animateWithDuration: (animated ? UINavigationControllerHideShowBarDuration : 0) animations: ^{
for (UIView* each in self.view.subviews) {
if (each == self.tabBar) {
[each setFrame: CGRectMake(each.frame.origin.x, screenHeight, each.frame.size.width, each.frame.size.height)];
} else {
[each setFrame: CGRectMake(each.frame.origin.x, each.frame.origin.y, each.frame.size.width, screenHeight)];
}
}
} completion: ^(BOOL finished) {
NSLog(#"Animation finished %d", finished);
}];
}
The problem is when I use the two at the same time (hiding/showing the nav and tab bar), it's not clean. If the navbar comes first, anything anchored to the bottom jumps (see example below), and if the tabbar comes first, the top jumps.
Example: I position the UIButton in the bottom right and set its autoresizing mask
resizeButton.frame = CGRectMake(self.view.bounds.size.width - 50, self.view.bounds.size.height - 100, 32, 32); // hardcoded just for testing purposes
resizeButton.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleTopMargin;
But when the navbar and tabbar are minimized the UIButton jumps between the two states (doesn't slide along with the tab bar). However, if I change it to attach to the top right, it slides perfectly with the nav bar.
Does anyone know how to solve this?
Edit:
This is the closet and most elegant solution I have so far (just trying to get a working concept):
[UIView animateWithDuration: UINavigationControllerHideShowBarDuration animations: ^{
if (self.isMaximized) {
self.tabBarController.view.frame = CGRectMake(0, 20, screenRect.size.width, screenRect.size.height + 49 - 20);
[self.navigationController setNavigationBarHidden:YES animated:YES];
} else {
self.tabBarController.view.frame = CGRectMake(0, 20, screenRect.size.width, screenRect.size.height - 20);
[self.navigationController setNavigationBarHidden:NO animated:YES];
}
} completion: ^(BOOL finished) {
NSLog(#"Frame done: %#", NSStringFromCGRect(self.view.frame));
return;
}];
On maximizing:
Slides the navbar up, and slides the tabbar down, at the same time
The top of the inner/content view slides up, and the bottom of this view jumps down
On minimizing:
Slides the navbar down, and slides the tabbar up, at the same time
The top of the inner/content view slides down properly, but the bottom jumps to the final value, leaving whitespace which is then covered by the sliding tabbar
If I rearange the order of the minimizing-animations (so the navbar animatino is called first), then the top in the inner/content view jumps
the solution i use should eliminate the jump problem you see.
this solution is derived from an Objective-C category found Carlos Oliva's github page, and while the copyright in that code is "all rights reserved", i wrote him and he provided permission for use.
my category code varies only slightly from his code. also, find below the category code the invocation code that i use in my app.
from UITabBarController+HideTabBar.m
// the self.view.frame.size.height can't be used directly in isTabBarHidden or
// in setTabBarHidden:animated: because the value may be the rect with a transform.
//
// further, an attempt to use CGSizeApplyAffineTransform() doesn't work because the
// value can produce a negative height.
// cf. http://lists.apple.com/archives/quartz-dev/2007/Aug/msg00047.html

// the crux is that CGRects are normalized, CGSizes are not.

}
from my ScrollableDetailImageViewController.m

}
Just try this code, If it is working. I have written this code a year before. But, still it works good for me.
I didn't used the block based animations. Because it was written when I am new to iOS. Just try and optimize yourself as you wanted.
- (void) hideTabBar:(UITabBarController *) tabbarcontroller {

// Method shows the bottom and top bars

Try this
you can hide tabbar contrller and navigation bar using animation like:-
-(IBAction)hide:(id)sender
{
[self hideShowBars];
}
- (void) hideShowBars
{
CGRect rect = self.navigationController.navigationBar.frame;
CGRect rect1 = self.tabBarController.tabBar.frame;
if(self.navigationController.navigationBar.isHidden)
{
[self.navigationController.navigationBar setHidden:NO];
rect.origin.y=self.view.frame.origin.y;
}
else
{
rect.origin.y=self.view.frame.origin.y-rect.size.height;
}
if(self.tabBarController.tabBar.isHidden)
{
[self.tabBarController.tabBar setHidden:NO];
rect1.origin.y=self.view.frame.size.height-rect1.size.height-rect1.size.height;
}
else
{
rect1.origin.y=self.view.frame.size.height;
}
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.50];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(hideShowBarsAnimationStopped)];
self.navigationController.navigationBar.frame=rect;
self.tabBarController.tabBar.frame = rect1;
[UIView commitAnimations];
}
- (void) hideShowBarsAnimationStopped
{
if(self.navigationController.navigationBar.frame.origin.y==self.view.frame.origin.y)
return;
if(!self.navigationController.navigationBar.isHidden)
{
[self.navigationController.navigationBar setHidden:YES];
}
if(!self.tabBarController.tabBar.isHidden)
{
[self.tabBarController.tabBar setHidden:YES];
}
}
This is an iPad project where I have a UIView with several subViews, and I am trying to animate one of this UIViews using [UIView transitionFromView:toView:duration:options:completion], but when I run this method the whole parent view gets flipped!
This is the code I'm using:
UIView *secondView = [[UIView alloc] initWithFrame:CGRectMake(200, 200, 300, 300)];
[newView setBackgroundColor:[UIColor redColor]];
[UIView transitionFromView:self.firstView.view toView:secondView duration:1.0 options:UIViewAnimationOptionTransitionFlipFromLeft completion:nil];
Any idea on how can I flip between this views without animating the whole parent view?
Thanks!
this code may helps you:
put the two views you want to flip inside an unnamed view with the same size
and link the IBOutlet UIView *newView,*oldView; to the views and put the new view on top
bool a = NO;
#implementation ViewController
- (IBAction)flip:(id)sender
{
if (a == NO) {
[UIView transitionFromView:oldView toView:newView
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromLeft
completion:NULL];
a = YES; // a = !a;
}
else {
[UIView transitionFromView:newView toView:oldView
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromLeft
completion:NULL];
a = NO; // a = !a;
}
}
I had problems getting this to work also. I used the code written by Floris, but although it worked for the first "flip" the next flip started to go weird where the buttons and labels on the frontside UI View lost there positions.
I put the code below into place and it is working fine.
Couple of things to note:
panelView is a UIView control on the ViewController that has two other UIViews nested inside it (subviews). The first one is called frontView, second one is called backView. (see picture below)
I have a bool property called displayingFront on the class
(in my .h)
#property BOOL displayingFront;
in my .m
#synthesize displayingFront;
in my viewDidLoad method
self.displayingFront = YES;
This is the code in the .m that i have rigged up to the two buttons if front and back UIViews...
- (IBAction)flip:(id)sender
{
[UIView transitionWithView:self.panelView
duration:1.0
options:(displayingFront ? UIViewAnimationOptionTransitionFlipFromRight :
UIViewAnimationOptionTransitionFlipFromLeft)
animations: ^{
if(displayingFront)
{
self.frontView.hidden = true;
self.backView.hidden = false;
}
else
{
self.frontView.hidden = false;
self.backView.hidden = true;
}
}
completion:^(BOOL finished) {
if (finished) {
displayingFront = !displayingFront;
}
}];
}
Use a container view to hold your subviews, and make the container view the same size as your subview that you're trying to animate.
So, you can setup your views like this.
self.view-> "a container view" -> subviews
**//flipping view continuously**
bool a = NO;
-(void)viewDidLoad
{
// THIS is the canvass holding the two views this view is flipping
UIView *v=[[UIView alloc]initWithFrame:CGRectMake(40, 40, 150, 150)];
v.backgroundColor=[UIColor clearColor];
[self.view addSubview:v];
[v addSubview:yourfirstview];
[v addSubview:yoursecondview];
// calling the method
[NSTimer scheduledTimerWithTimeInterval:2.0
target:self
selector:#selector(flip)
userInfo:nil
repeats:YES];
}
//flipping view randomly
-(void)flip
{
if (a == NO)
{
[UIView transitionFromView:yourfirstview toView:yoursecondview duration:1.0 options:UIViewAnimationOptionTransitionFlipFromLeft completion:NULL];
a = YES;
}
else if(a==YES)
{
[UIView transitionFromView:yoursecondview toView:yourfirstview duration:1.0 options:UIViewAnimationOptionTransitionFlipFromLeft completion:NULL];
a = NO;
}
}
I fixed this problem by using old-school animations:
[UIView beginAnimations:#"Flip" context:nil];
[UIView setAnimationDuration:1];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:firstView cache:YES];
[self addSubview:secondView];
[UIView commitAnimations];
Additionally you can remove the firstView:
[firstView removeFromSuperview];
I'd like to make an update of Steve Parker's answer in SWIFT 4:-
var displayBlankView:Bool = true
UIView.transition(with:flipView, duration:1.0, options:displayBlankView ? .transitionFlipFromLeft:.transitionFlipFromRight, animations:{
if(self.displayBlankView){
self.view1.isHidden=true
self.view2.isHidden=false
}else{
self.view1.isHidden=false
self.view2.isHidden=true
}
}, completion:{
(finished: Bool) in
self.displayBlankView = !self.displayBlankView;
})

There are a four things. First, you should be positioning the banner off screen in your viewDidLoad method because it will just show an empty frame when you first launch and will more than likely get rejected because of it.
Secondly, you are setting up your banner view incorrectly. I think the frame is still CGZero. Thirdly you are not setting the bannerView's delegate. Try the following:
-(void)viewDidLoad{
CGRect frame=CGRectZero;
frame.size = [ADBannerView sizeFromBannerContentSizeIdentifier:ADBannerContentSizeIdentifierPortrait];
// Place frame at the bottom edge of the screen out of sight
frame.origin = CGPointMake(0.0, CGRectGetMaxY(self.view.bounds));
// Now to create and configure the banner view
ADBannerView *adView = [[ADBannerView alloc] initWithFrame:frame];
adView.requiredContentSizeIdentifiers = [NSSet setWithObject:ADBannerContentSizeIdentifierPortrait];
// Set the delegate to self, so that we are notified of ad responses
adView.delegate = self;
[self.view addSubview: adView];
}
Fourth, in your bannerViewDidLoadAd: method you are not animating the banner ad into place. Try this:
- (void)bannerViewDidLoadAd:(ADBannerView *)banner
{
// Get a brand new frame
CGRect newFrame=CGRectZero;
CGPoint frameOrigin=CGPointZero;
// Set the origin
frameOrigin=CGPointMake(0.0, CGRectGetMaxY(self.view.bounds));
newFrame.origin=frameOrigin;
// Set the size
newFrame.size=[ADBannerView sizeFromBannerContentSizeIdentifier:ADBannerContentSizeIdentifierPortrait];
CGFloat bannerHeight = newFrame.size.height;
CGFloat bannerOffset=0.0;
// Determine where the new frame should be
if (!self.bannerIsVisible)
{
// It should be visible, raise it up
bannerOffset=-bannerHeight;
}
CGRect offSetRect=CGRectOffset(newFrame,0.0f,bannerOffset);
[UIView animateWithDuration:0.2
animations:^{banner.view.frame=offSetRect}
completion:^(BOOL finished){
if (bannerOffSet<0){
self.bannerIsVisible=YES;
}else{
self.bannerIsVisible=NO;
}
}
];
}
of course if the banner is supposed to be positioned at the top of the screen, you can probably figure out how things need to be modified, but this gets you in going in the right direction.
Good luck
Not sure by reading your question, but do be aware that Apple simulates iAds not being available. Sometimes you need to try multiple times before the sample ad comes through.
I have this lovely nav bar asset:
navBar view http://dl.dropbox.com/u/1734050/ViewWithNavBar.jpg
and when users tap on the middle button (one with the arrows) it will bring up this other lovely "share box" asset
shareBox dropdown from navBar http://dl.dropbox.com/u/1734050/navBarWithShareBox.jpg
What I have in the code so far is that when the screen is tapped, the nav bar will appear, and disappear on another tap. Secondly, when the user taps on the "share" button, the share box comes up, and the user can tap outside of the box to dismiss it.
Here is the problem: I cannot dismiss the nav bar after bringing up the share box!
Here is some code:
-(void)viewDidLoad {
...
...
...
UITapGestureRecognizer *tapNavBar = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleTapForNavBar:)];
self.tapForNavBar = tapNavBar;
[self.viewForTaps addGestureRecognizer:self.tapForNavBar];
// btw, tapForNavBar is a UITapGestureRecognizer instance variable.
// also, viewForTaps is a view (instance variable) I made to handle
// where the user could tap (most of the screen)
}
#pragma mark -
#pragma mark Tap and Gesture Methods
-(void)handleTapForNavBar:(UIGestureRecognizer *)gestureRecognizer {
if (self.navBarIsHidden) {
[UIView animateWithDuration:0.5 animations:^ {
//self.primeViewController.view.alpha = 0.8;
self.navBar.alpha = 1.0;
}];
self.detailViewButton.userInteractionEnabled = YES;
self.shareButton.userInteractionEnabled = YES;
self.aboutAppButton.userInteractionEnabled = YES;
self.navBarIsHidden = NO;
}
else {
[UIView animateWithDuration:0.5 animations:^ {
self.navBar.alpha = 0.0;
//self.primeViewController.view.alpha = 1.0;
}];
self.detailViewButton.userInteractionEnabled = NO;
self.shareButton.userInteractionEnabled = NO;
self.aboutAppButton.userInteractionEnabled = NO;
self.navBarIsHidden = YES;
}
}
Ok, so that should look all dandy (and works like it too!) -- now here is perhaps where it gets unorthodox?
-(IBAction)showShareMenu:(id)sender {
if (self.navBarShareBoxIsHidden) {
[UIView animateWithDuration:0.5 animations:^ {
self.navBarShareBox.alpha = 1.0;
}];
[self.tapForNavBar removeTarget:nil action:NULL];
UITapGestureRecognizer *tapShareBox = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleTapForShareBox:)];
self.tapForShareBox = tapShareBox;
[self.viewForTaps addGestureRecognizer:self.tapForShareBox];
self.navBarShareBoxIsHidden = NO;
self.twitterButton.userInteractionEnabled = YES;
self.facebookButton.userInteractionEnabled = YES;
self.googlePlusButton.userInteractionEnabled = YES;
}
else {
[UIView animateWithDuration:0.5 animations:^ {
self.navBarShareBox.alpha = 0.0;
}];
[self.tapForShareBox removeTarget:nil action:NULL];
[self.tapForNavBar addTarget:self action:#selector(handleTapForNavBar:)];
self.navBarShareBoxIsHidden = YES;
self.twitterButton.userInteractionEnabled = NO;
self.facebookButton.userInteractionEnabled = NO;
self.googlePlusButton.userInteractionEnabled = NO;
}
}
I then create this method to handle the specific shareBox tapping:
-(void)handleTapForShareBox:(UIGestureRecognizer *)gestureRecognizer {
if (!self.navBarShareBoxIsHidden) {
[UIView animateWithDuration:0.5 animations:^ {
self.navBarShareBox.alpha = 0.0;
}];
self.navBarShareBoxIsHidden = YES;
self.twitterButton.userInteractionEnabled = NO;
self.facebookButton.userInteractionEnabled = NO;
self.googlePlusButton.userInteractionEnabled = NO;
[self.tapForShareBox removeTarget:nil action:NULL];
[self.tapForNavBar addTarget:self action:#selector(handleTapForNavBar:)];
}
}
I'm assuming my problem is coming from alloc/initing the new UITapGestureRecognizer in the -(IBAction)showShareMenu method. I thought by using the removeTarget... and addTarget messages I could easily tell my code which TapGesture method it should use, but considering it isn't working, I was wrong! Where did I go wrong? If you need more info, I'd be happy to give more.
Ah Ha! Looks like I found a solution! In my handleTapForShareBox method I did this:
-(void)handleTapForShareBox:(UIGestureRecognizer *)gestureRecognizer {
if (!self.navBarShareBoxIsHidden) {
[UIView animateWithDuration:0.5 animations:^ {
self.navBarShareBox.alpha = 0.0;
}];
self.navBarShareBoxIsHidden = YES;
self.twitterButton.userInteractionEnabled = NO;
self.facebookButton.userInteractionEnabled = NO;
self.googlePlusButton.userInteractionEnabled = NO;
[self.tapForShareBox removeTarget:nil action:NULL];
//[self.tapForNavBar addTarget:self action:#selector(handleTapForNavBar:)];
// Here is the new stuff, I added another alloc init of a UITapGestureRecognizer
// and re-assigned it to my UITap instance variable
UITapGestureRecognizer *tapNavBar = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleTapForNavBar:)];
self.tapForNavBar = tapNavBar;
[self.viewForTaps addGestureRecognizer:self.tapForNavBar];
}
}
It works great now! However, there were a couple things:
1) Do I have to release the UITapGestureRecognizer local pointer I created? Or because I initWithTarget it will be autoreleased?
2) Is this a hack? Or is this a proper way of passing different tap methods around? I'm just a little confused why the removeTarget and addTarget didn't do the trick.
