All,
I want to add UISearchBar to UINavigationbar, I dont dont want to use UISearchController, Just UISearchbar programmatically and it must work in landscape as well.
I tried it is working well in Portrait well, but in Landscape, i have issues in iPhone X width. Can we use Constraints.
Below is the code
CGFloat width = [UIScreen mainScreen].bounds.size.width;
search = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, width - 2 * 44 - 2 * 15, 44)];
search.delegate = self; // search.tintColor = [UIColor redColor];
search.searchBarStyle = UISearchBarStyleMinimal;
search.placeholder = #"Search";
search.translucent = NO;
search.opaque = NO;
search.showsCancelButton = NO;
[search setBackgroundImage:[[UIImage alloc] init]];
//customize textfield inside UISearchBar
#try {
for (id object in [[[search subviews] firstObject] subviews])
{
if (object && [object isKindOfClass:[UITextField class]])
{
UITextField *textFieldObject = (UITextField *)object;
textFieldObject.backgroundColor = [UIColor whiteColor];
textFieldObject.borderStyle = UITextBorderStyleRoundedRect;
textFieldObject.layer.borderColor = (__bridge CGColorRef _Nullable)([brandingObj getValueForKey:navBarTitleColor]);
textFieldObject.layer.borderWidth = 1.0;
break;
}
}
}
#catch (NSException *exception) {
NSLog(#"Error while customizing UISearchBar");
}
#finally {
}
I don't understand why you want to use UISearchDisplayController, its highly configurable and recommended by apple, working with geometry (CGRecr, CGFrame, etc.) to adjust UIKit objects layout could be a pain, use auto layout avoiding UIKits convenience initializers, to adjust later constraints.
Anyway if you want explicitly do with this way, this should work.
#import "ViewController.h"
#interface ViewController ()<UISearchBarDelegate>
#property UISearchBar *searchbar;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
_searchbar = [UISearchBar new];
_searchbar.delegate = self;
_searchbar.searchBarStyle = UISearchBarStyleMinimal;
self.navigationItem.titleView = self.searchbar;
// Do any additional setup after loading the view, typically from a nib.
}
Maybe you should need configure appearance , take a look here
Cheers.

When i try to add ATMHud to uitableviewcontroller subview it does work but it doesn't disable the scrolling and if the tableview is not on top i can't see the hud view. What i did was added to teh tabBarController.view that works but i want find out if this is a good idea or later on i might have issues with it.
Another question is tabBarController.view frame is that the whole screen or just the bottom part. How come atmhud shows in the middle of the screen?
Thanks in advance!
Yan
============
Found a blog post that shows how to reset self.view and add tableview separately in uitableviewcontroller
UITableViewController and fixed sub views
- (void)viewDidLoad {
[super viewDidLoad];
if (!tableView &&
[self.view isKindOfClass:[UITableView class]]) {
tableView = (UITableView *)self.view;
}
self.view = [[[UIView alloc] initWithFrame:
[UIScreen mainScreen].applicationFrame] autorelease];
self.tableView.frame = self.view.bounds;
self.tableView.contentInset = UIEdgeInsetsMake(44.0, 0.0, 0.0, 0.0);
[self.view addSubview:self.tableView];
UIView *fixedBar = [[UIView alloc] initWithFrame:
CGRectMake(0.0, 0.0, self.view.bounds.size.width, 44.0)];
fixedBar.backgroundColor = [UIColor colorWithRed:
0.0 green:1.0 blue:0.0 alpha:0.7];
[self.view addSubview:fixedBar];
[fixedBar release];
}
After this when add hud to self.view you will be able to disable the tableview on the bottom.
Let me know if this a good way to setup the tableview
The problem with using the tab bar is that the hud is now modal, and the user cannot change the tab.
It sounds like the tableview is not your primary viewm, as it can get "covered up". If its not the primary view, then add the ATMHud to self.view. If the tableView is the same as self.view, then add a new transparent view to it, then add the HUD to that view.
The tabBarController.view is the view that hosts the tabbed views - if you want to see its size (or frame) log it using NSStringFromCGRect(self.tabBarController.frame);
EDIT: I just did a test, the ATMHud DOES block the UI. All I can think of is that you have not inserted it where you need to (at the top of current view's subviews.) I have a demo project where I do this:
hud = [[ATMHud alloc] initWithDelegate:self];
[self.view addSubview:hud.view];
[hud setCaption:#"Howdie"];
[hud setActivity:YES];
[hud show];
[hud hideAfter:5];
A button under the hud is not active - in fact nothing in the view is active (probably the Nav Bar would be live though)
If you want an ARCified and field tested version, you can grab it here
EDIT2: The solution to your problem is below. Note that ATMHud blocks clicks from getting to the table, and the code below stops the scrolling:
- (void)hudWillAppear:(ATMHud *)_hud
{
self.tableView.scrollEnabled = NO;
}
- (void)hudDidDisappear:(ATMHud *)_hud
{
self.tableView.scrollEnabled = YES;
}
Dump the views:
#import <QuartzCore/QuartzCore.h>
#import "UIView+Utilities.h"
#interface UIView (Utilities_Private)
+ (void)appendView:(UIView *)v toStr:(NSMutableString *)str;
#end
#implementation UIView (Utilities_Private)
+ (void)appendView:(UIView *)a toStr:(NSMutableString *)str
{
[str appendFormat:#" %#: frame=%# bounds=%# layerFrame=%# tag=%d userInteraction=%d alpha=%f hidden=%d\n",
NSStringFromClass([a class]),
NSStringFromCGRect(a.frame),
NSStringFromCGRect(a.bounds),
NSStringFromCGRect(a.layer.frame),
a.tag,
a.userInteractionEnabled,
a.alpha,
a.isHidden
];
}
#end
#implementation UIView (Utilities)
+ (void)dumpSuperviews:(UIView *)v msg:(NSString *)msg
{
NSMutableString *str = [NSMutableString stringWithCapacity:256];
while(v) {
[self appendView:v toStr:str];
v = v.superview;
}
[str appendString:#"\n"];
NSLog(#"%#:\n%#", msg, str);
}
+ (void)dumpSubviews:(UIView *)v msg:(NSString *)msg
{
NSMutableString *str = [NSMutableString stringWithCapacity:256];
if(v) [self appendView:v toStr:str];
for(UIView *a in v.subviews) {
[self appendView:a toStr:str];
}
[str appendString:#"\n"];
NSLog(#"%#:\n%#", msg, str);
}
#end
In my TestApp, I created a class "Carousel" which should let me create a swipe menu with a UIPageControl in an easy way (by simply creating an instance of the class Carousel).
Carousel is a subclass of UIView
At init, it creates an UIView, containing UIScrollView, UIPageControl
I can add further UIViews to the scroll view
I don't know if this is the proper way to do it, but my example worked quite well in my TestApp. Swiping between pages works perfectly and the display of the current page in the UIPageControl is correct.
If there were not one single problem: The UIPageControl sometimes reacts to clicks/taps (I only tested in Simulator so far!), sometimes it doesn't. Let's say most of the time it doesn't. I couldn't find out yet when it does, for me it's just random...
As you can see below, I added
[pageControl addTarget:self action:#selector(pageChange:) forControlEvents:UIControlEventValueChanged];
to my code. I thought this would do the proper handling of taps? But unfortunately, pageChange doesn't get always called (so the value of the UIPageControl doesn't change every time I click).
I would appreciate any input on this because I couldn't find any solution on this yet.
This is what I have so far:
Carousel.h
#import <UIKit/UIKit.h>
#interface Carousel : UIView {
UIScrollView *scrollView;
UIPageControl *pageControl;
BOOL pageControlBeingUsed;
}
- (void)addView:(UIView *)view;
- (void)setTotalPages:(NSUInteger)pages;
- (void)setCurrentPage:(NSUInteger)current;
- (void)createPageControlAt:(CGRect)cg;
- (void)createScrollViewAt:(CGRect)cg;
#end
Carousel.m
#import "Carousel.h"
#implementation Carousel
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
// Create a scroll view
scrollView = [[UIScrollView alloc] init];
[self addSubview:scrollView];
scrollView.delegate = (id) self;
// Init Page Control
pageControl = [[UIPageControl alloc] init];
[pageControl addTarget:self action:#selector(pageChange:) forControlEvents:UIControlEventValueChanged];
[self addSubview:pageControl];
}
return self;
}
- (IBAction)pageChange:(id)sender {
CGRect frame = scrollView.frame;
frame.origin.x = frame.size.width * pageControl.currentPage;
frame.origin.y = 0;
[scrollView scrollRectToVisible:frame animated:TRUE];
NSLog(#"%i", pageControl.currentPage);
}
- (void)addView:(UIView *)view {
[scrollView addSubview:view];
}
- (void)createPageControlAt:(CGRect)cg {
pageControl.frame = cg;
}
- (void)setTotalPages:(NSUInteger)pages {
pageControl.numberOfPages = pages;
}
- (void)setCurrentPage:(NSUInteger)current {
pageControl.currentPage = current;
}
- (void)createScrollViewAt:(CGRect)cg {
[scrollView setPagingEnabled:TRUE];
scrollView.frame = cg;
scrollView.contentSize = CGSizeMake(scrollView.frame.size.width*pageControl.numberOfPages, scrollView.frame.size.height);
[scrollView setShowsHorizontalScrollIndicator:FALSE];
[scrollView setShowsVerticalScrollIndicator:FALSE];
}
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
float frac = scrollView.contentOffset.x / scrollView.frame.size.width;
NSUInteger page = lround(frac);
pageControl.currentPage = page;
}
#end
ViewController.m (somewhere in viewDidLoad)
Carousel *carousel = [[Carousel alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
for (int i=0; i<5; i++) {
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(i * 320, 0, 320, 420)];
UIColor *color;
if(i%3==0) color = [UIColor blueColor];
else if(i%3==1) color = [UIColor redColor];
else color = [UIColor purpleColor];
view.backgroundColor = color;
[carousel addView:view];
view = nil;
}
[carousel setTotalPages:5];
[carousel setCurrentPage:0];
[carousel createPageControlAt:CGRectMake(0,420,320,40)];
[carousel createScrollViewAt:CGRectMake(0,0,320,420)];
Your code is correct. Most likely the frame of your pageControl is pretty small, so theres not a lot of area to look for touch events. You would need to increase the size of the height of pageControl in order to make sure taps are recognized all of the time.
I have a little problem with adding a subview to my UIKeyboard. I can successfully locate my keyboard and add an uiimageview to it, but unfortunately the button under the image view still can be touched. I just wanted to make it a color overlay, which would hide the unneeded keys and also make them untouchable :)
Here is my code, what am I doing wrong? The UIImageView displays correctly, but the buttons still can be tapped... :(
- (UIView *)findKeyboard {
// Locate non-UIWindow.
UIWindow *keyboardWindow = nil;
for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) {
if (![[testWindow class] isEqual:[UIWindow class]]) {
keyboardWindow = testWindow;
break;
}
}
// Locate UIKeyboard.
UIView *foundKeyboard = nil;
for (UIView __strong *possibleKeyboard in [keyboardWindow subviews]) {
// iOS 4 sticks the UIKeyboard inside a UIPeripheralHostView.
if ([[possibleKeyboard description] hasPrefix:#"<UIPeripheralHostView"]) {
possibleKeyboard = [[possibleKeyboard subviews] objectAtIndex:0];
}
if ([[possibleKeyboard description] hasPrefix:#"<UIKeyboard"]) {
foundKeyboard = possibleKeyboard;
break;
}
}
return foundKeyboard;
}
- (void)keyboardWillShow:(NSNotification *)note {
UIImageView *overlayView;
UIView *keyboardView = [self findKeyboard];
UIImage *img = [UIImage imageNamed:#"keyboardOverlay.png"];
overlayView = [[UIImageView alloc] initWithImage:img];
[overlayView setUserInteractionEnabled:NO];
UIView *newView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, overlayView.frame.size.width, overlayView.frame.size.height)];
newView.userInteractionEnabled = NO;
newView.multipleTouchEnabled = NO;
[newView addSubview:overlayView];
[keyboardView insertSubview:newView atIndex:40];
}
User interaction being disabled means that touches are passed straight through. Enable it, but don't have any gesture recognisers or actions, and it will swallow all touches.
I am building an application (without interface builder!) which 'lives' in the NSStatusBar; when you click on an icon in the StatusBar a NSWindow with a NSScrollView appears. The window appears but it seems that something is preventing user interaction with the ScrollView
To find out where the problem comes from I also added my view to the main windows contentView in the AppDelegate, strange thing is that the scrollview is interactive in the MainWindow... Anyone knows why it doesn't work in my new Window?
This is the code I use to create the new TTDropDownWindow:
- (void)openWindow {
// Dropdown
if (self.dropDownWindow == nil) {
self.dropDownWindow = [[TTDropDownWindow alloc] init];
self.dropDownWindow.releasedWhenClosed = NO;
self.dropDownWindow.contentView = self.view;
self.dropDownWindow.backgroundColor = [NSColor clearColor];
self.dropDownWindow.delegate = self;
self.dropDownWindow.alphaValue = 1;
self.dropDownWindow.hasShadow = NO;
self.dropDownWindow.opaque = NO;
}
[[NSApplication sharedApplication] activateIgnoringOtherApps:YES];
NSRect statusBarContentRect = self.statusBarItemView.window.frame;
NSPoint statusBarOriginPoint = NSMakePoint(NSMidX(statusBarContentRect), NSMinY(statusBarContentRect));
NSRect screenFrame = self.dropDownWindow.screen.frame;
NSRect dropDownContentRect = NSZeroRect;
dropDownContentRect.size.width = DROP_DOWN_WIDTH;
dropDownContentRect.size.height = DROP_DOWN_HEIGHT;
dropDownContentRect.origin.x = statusBarOriginPoint.x - DROP_DOWN_WIDTH / 2;
dropDownContentRect.origin.y = screenFrame.size.height - DROP_DOWN_HEIGHT - NSStatusBar.systemStatusBar.thickness;
[self.dropDownWindow setFrame:dropDownContentRect display:YES];
[self.dropDownWindow makeKeyAndOrderFront:nil];
}
This is the implementation of TTDropDownWindow:
#import "TTDropDownWindow.h"
#import "WFConstants.h"
#implementation TTDropDownWindow
- (id) init
{
self = [super initWithContentRect:NSMakeRect(0, 0, DROP_DOWN_WIDTH, DROP_DOWN_HEIGHT) styleMask:NSBorderlessWindowMask backing:NSBackingStoreRetained defer:NO];
return self;
}
- (BOOL)canBecomeMainWindow {
return YES;
}
- (BOOL)canBecomeKeyWindow {
return YES;
}
#end
And this is the code that creates the View and the ScrollView
#import "TTStatusBarDropDownView.h"
#import "TTTestView.h"
#implementation TTStatusBarDropDownView
#synthesize dropDownTableViewData = dropDownTableViewData_;
- (id)initWithFrame:(NSRect)frameRect {
self = [super initWithFrame:frameRect];
if (self) {
NSImageView *imageView = [[NSImageView alloc] initWithFrame:frameRect];
imageView.image = [NSImage imageNamed:#"background-dropdown"];
[self addSubview:imageView];
// first create a view to put in a ScrollView
NSView *scrollViewHolder = [[TTTestView alloc] initWithFrame:NSMakeRect(19, 98, 414, 543) andColor:[NSColor yellowColor]];
[self addSubview:scrollViewHolder];
// create the scrollView
NSScrollView *scrollView = [[NSScrollView alloc] initWithFrame:NSMakeRect(0, 0, 414, 543)];
scrollView.hasVerticalRuler = YES;
scrollView.hasVerticalScroller = YES;
[scrollViewHolder addSubview:scrollView];
// TTTestView is just a NSView with a background drawing
TTTestView *theViewThatScrolls = [[TTTestView alloc] initWithFrame:NSMakeRect(0, 0, 200, 10000) andColor:[NSColor blueColor]];
[theViewThatScrolls addSubview:[[TTTestView alloc] initWithFrame:NSMakeRect(10, 10, 100, 8000) andColor:[NSColor grayColor]]];
[scrollView setDocumentView:theViewThatScrolls];
}
return self;
}
#end
You might change NSBackingStoreRetained to NSBackingStoreBuffered as stated over here:
NSScrollView in a NSWindow
I want to load a UIView as the first page and some UIImageViews after that. The UIImageViews load fine, but the first UIView shows blank.
I designed the UIView in storyboard. It has some UIButtons and few other controls. What am I doing wrong?
I created the project from the default pageController template.
ModelController.m
- (id)init
{
self = [super init];
if (self) {
// Create the data model.
/*
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
_pageData = [[dateFormatter monthSymbols] copy];
*/
NSMutableArray *imageViews = [[NSMutableArray alloc] init];
FirstViewController *firstViewController = [[FirstViewController alloc] init];
firstViewController.view.frame = CGRectMake([UIScreen mainScreen].bounds.origin.x,[UIScreen mainScreen].bounds.origin.y,[[UIScreen mainScreen] bounds].size.height, [[UIScreen mainScreen] bounds].size.width);
[imageViews addObject:firstViewController];
for (int i=1; i<=19; i++) {
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:#"picture%i.jpg", i]]];
imageView.frame = CGRectMake([UIScreen mainScreen].bounds.origin.x,[UIScreen mainScreen].bounds.origin.y,[[UIScreen mainScreen] bounds].size.height, [[UIScreen mainScreen] bounds].size.width);
[imageViews addObject:imageView];
}
_pageData = imageViews;
}
return self;
}
- (DataViewController *)viewControllerAtIndex:(NSUInteger)index storyboard:(UIStoryboard *)storyboard
{
// Return the data view controller for the given index.
if (([self.pageData count] == 0) || (index >= [self.pageData count])) {
return nil;
}
// Create a new view controller and pass suitable data.
DataViewController *dataViewController = [storyboard instantiateViewControllerWithIdentifier:#"DataViewController"];
dataViewController.dataObject = [self.pageData objectAtIndex:index];
if(index == 0)
{
//[dataViewController addChildViewController:[self.pageData objectAtIndex:index]];
FirstViewController *firstViewController = [self.pageData objectAtIndex:index];
[dataViewController.view addSubview:firstViewController.view];
}
else
{
UIImageView *imageView = [self.pageData objectAtIndex:index];
[dataViewController.view addSubview:imageView];
}
return dataViewController;
}
You haven't provided enough context to be certain, but it appears that what you need to load from the storyboard initially is an instance of FirstViewController, not an instance of UIView, so you'd need to do something like this instead of what you're currently doing:
FirstViewController *firstViewController = [self.storyboard instantiateInitialViewController];
// Note: If you need to adjust the frame of the controller's view, use the screen's
// application frame rather than its bounds.
controller.view.frame = [UIScreen mainScreen].applicationFrame;
Also, this seems like a bad idea, since you later fill the rest of the array with instances of UIImageView:
[imageViews addObject:firstViewController];
Why not add the controller's view to the array? Then you could eliminate the conditional logic in your viewControllerAtIndex:storyboard: method. Also, it's not clear why you're passing the storyboard in as an argument rather than using the built-in property, or for that matter, what class the code you posted belongs to, and what its relation is to the rest of your app. Maybe you could provide a little more info about that.
I got it to working by adding a xib file for FirstViewController. What ever I design in the xib shows up well. Previously I was designing it in the storyboard.
