What I am trying to do is display a label on loading view for first time. When User will tap an object, that label should disappear and three circles should appear on its position. But what is happening is that my label is not hidden when I am trying to release it, as I will be needing it no more. Also it is not present at position I want.
What I have done is:
#interface AnimateCircle : UIViewController
{
UILabel *text;
CALayer *smallCircle1;
CALayer *smallCircle2;
CALayer *smallCircle3;
}
and then declared property for label and synthesized it. Please note that I have added AnimateCircle as subview of a view. So my subview is starting from small circles as indicated in 2nd figure.
In viewDidLoad, I wrote:
text = [[UILabel alloc] initWithFrame:CGRectMake(10, 5, 310, 100)];
text.text = #"Tap the Red Button To Start The Timer...!";
text.font = [UIFont fontWithName:#'SnellRoundHand-Bold" size:8];
[self.view addSubview:text];
[text release];
At tap Gesture, I call a method in which I release my label text to hide it.
[text removeFromSuperView];
and draw three circles at its position. Just showing position...
smallCircle1.frame = CGRectMake(100, 15, 30, 30);
smallCircle2.frame = CGRectMake(140, 15, 30, 30);
smallCircle3.frame = CGRectMake(180, 15, 30, 30);
Failed after struggling for 2 hours. Please can someone tell me that what am I missing? Thanks a lot...
You must actually add the 3 circles to the view.
Use self.view.layer addSublayer:.

I am trying to create a UIButton programmatically instead of using the interface builder. I initialize and set the button frame but the button doesn't seem to appear on the view. My code is as follows:
UIButton *showInfoButton = [[UIButton alloc] init];
CGRect buttonFrame = CGRectMake(0,0, 150, 150);
showInfoButton.frame = buttonFrame;
What am I missing? Please bear with me as I am new to iOS.
You forgot to add your UIButton as a subview to the UIView you want it to display on. Since you are building UI programmatically, you need to manually add the button as a subview to the container view.
You can do so by using this line of code:
[self.view addSubview:showInfoButton];
The button might not still appear as you are making a custom button which has a transparent background colour. In order to see the button, you can set the UIButton's backgroundColor property as follows:
[showInfoButton setBackgroundColor:[UIColor blackColor]];
I can display the UIScrollView indicator but I cant physically scroll down to view the hidden content. I’ve used this code in my viewDidLoad:
self.scroller.contentSize = CGSizeMake(320, 600);
self.scroller.frame = CGRectMake(320,480,320,480);
Can anybody out their help me out please?
// define the area that is initially visible
scrollViewCustom.frame = CGRectMake(0, 5, 354, 500);
// then define how much a user can scroll it
[scrollViewCustom setContentSize:CGSizeMake(354, 960)];
In addition,clear the background color of scroll view to show the text.
scrollViewCustom.backgroundColor = [UIColor clearColor];
I've been trying to use insertSubview:atIndex: to insert a subview under another one. The problem is that most of the time it's not the view with the higher index that is above, but the view that was added last. I noticed that this works fine if I pick indexes 0 and 1 but in my case one view needs to be at least at the index 12 and the other one needs to be above.
Here is some code as an example:
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(20, 100, 100, 100)];
label.text=#"LABEL";
[label setBackgroundColor:[UIColor whiteColor]];
[self.view insertSubview:label atIndex:13];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn.frame=CGRectMake(20, 100, 100, 100);
[btn setBackgroundColor:[UIColor whiteColor]];
[self.view insertSubview:btn atIndex:12];
I know I could insert the label after the button but that wouldn't solve the problem in my case.
What am I doing wrong?
Thank you in advance for your help.
It doesn’t work like the CSS z-index—if a view has k subviews, inserting a view at any index higher than k will have the same effect as adding it at index k, or, in other words, adding it as the last (frontmost) subview. The subviews are maintained as a continuous list, not an arbitrarily-indexed array. In your case, you probably don’t have 14 subviews to start out with, so inserting one view at 13 and another at 12 isn’t having the effect you want.
Is there any way to use autoresizing masks to move my content so that the delete button doesn't cover it up? Googling has told me that I need to set an autoresizing mask of UIViewAutoresizingFlexibleRightMargin on my subview. It seems to me like UIViewAutoresizingFlexibleWidth would actually make more sense; though I've tried them both and neither works.
The view that I am trying to shrink is just a label that is a subview of the cell's contentView. I am unsure if the contentView itself automatically resizes when the delete button shows up; but it seems like it isn't; otherwise my autoresizing mask should have worked.
If the presence of the delete button doesn't cause any views to be resized; is there anyway that I can do this manually?
You should use UIViewAutoresizingFlexibleLeftMargin.
Here's why. You want your contents to move to the left, basically making it seem like the delete button is pushing the contents to the left, out of it's way. flexibleLeftMargin basically means your UILabel will stay fixed to the right side of your contentView. The reason you want this, is because the delete button actually causes your contentView to shrink it's width.
The autoresizingmask of your UILabel refers to how it behaves inside the contentView, not the cell.
Give it a try, it should work.
This question is really old but I feel I should answer this anyway since I just found the solution myself.
Only the cell's ContentView gets resized with the confirmation button is shown. If you don't add your views (labels, imageviews, etc...) to the cell.contentView instead of adding them to the cell directly then they won't be resized when the contentView is resized. In my case, I was adding it to the cell directly.
So, instead of doing something like:
UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(5, 5, width-10, 20)];
[nameLabel setFont:[UIFont boldSystemFontOfSize:16]];
[nameLabel setHighlightedTextColor:[UIColor whiteColor]];
[nameLabel setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
[nameLabel setTag:101];
[cell addSubview:nameLabel];
[nameLabel release];
you should do:
UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(5, 5, width-10, 20)];
[nameLabel setFont:[UIFont boldSystemFontOfSize:16]];
[nameLabel setHighlightedTextColor:[UIColor whiteColor]];
[nameLabel setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
[nameLabel setTag:101];
[[cell contentView] addSubview:nameLabel]; // <<--- note the change in this line!
[nameLabel release];
Hope this helps others who stumble upon this issue.
I am using iOS 7, I got the same issue. I am using a separate xib for the UITableViewCell with auto layout enabled, so just added one more constraint to the label so that it will have a fixed gap on its right side.
When using UISplitViewController on the iPad there's a black vertical divider line between the root and detail view. Is there any way to remove this line?
Thanks
Excellent answer by #bteapot. I tested this and it works, even gets rid of the line between master/detail nav bars.
You can do this in storyboard by adding the "gutterWidth" key path and the value 0 to the USplitViewController runtime attributes.
Actuly I have some modification to answer of (Dylan)'s answer
in the appDelegate we need to add image in spliteview controller rather then window
self.splitViewController.view.opaque = NO;
imgView = [[UIImageView alloc] initWithImage:
[UIImage imageNamed:#"FullNavBar.png"]];
[imgView setFrame:CGRectMake(0, 0, 1024, 44)];
[[self.splitViewController view] insertSubview:imgView atIndex:0];
[[self.splitViewController view] setBackgroundColor:[UIColor clearColor]];
here self is object of AppDelegate.
now Apply the answer of this thread : iPhoneOS SDK - Remove Corner Rounding from views (iPad problem) answer by (abs)
edit in above post's answer is
-(void) fixRoundedSplitViewCorner {
[self explode:[[UIApplication sharedApplication] keyWindow] level:0];
}
-(void) explode:(id)aView level:(int)level
{
if ([aView isKindOfClass:[UIImageView class]]) {
UIImageView* roundedCornerImage = (UIImageView*)aView;
roundedCornerImage.hidden = YES;
}
if (level < 2) {
for (UIView *subview in [aView subviews]) {
[self explode:subview level:(level + 1)];
}
}
imgView.hidden = FALSE;
}
** make imgView.hidden to FALSE
declare imgView to the AppDelegate.h file**
and dont forget to call this
-(void)didRotateFromInterfaceOrientation:
UIInterfaceOrientation)fromInterfaceOrientation
{
[yourAppDelegate performSelector:#selector(fixRoundedSplitViewCorner)
withObject:NULL afterDelay:0];
}
chintan adatiya answer covers only the corners and the navigation bar, but I found an trick how to cover the line between the Master and the Detail view.
It is not nice but it works like a charm.
First create an image which is 1 px wide and 704 pixels high.
In the didFinishLaunchingWithOptions add the following code:
UIView *coverView = [[UIView alloc] initWithFrame:CGRectMake(320, 44, 1, 704)];
[coverView setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:#"divider_cover.png"]]];
[splitViewController.view addSubview:coverView];
And done.
When you want a background image which is continues create 3 images:
Master: width: 320, height: 704
Detail: width: 703, height: 704
Divider:width: 1, height: 704
First post here, hi everyone.
I discovered how to do it accidentally... when I tried to find why I had LOST the divider line. Here's how to hide it, if you're still interested:
1) In your Detail (right-side) view, make sure you have a subview that spans the whole view.
2) Offset this subview view to (-1, 0).
3) Make sure that the Detail View has its "Clip Subviews" option unchecked.
Voilà, enjoy.
You can mostly get rid of it by setting another image behind it in the main window's views. This is from the app delegate didFinishLaunchingWithOptions
// Add the split view controller's view to the window and display.
splitViewController.view.opaque = NO;
splitViewController.view.backgroundColor = [UIColor clearColor];
[window addSubview:splitViewController.view];
[window insertSubview:bgImageView belowSubview:splitViewController.view];
[window makeKeyAndVisible];
But it still leaves two visual artifacts at the top and the bottom that appear to be custom drawn by the splitviewcontroller.
Interestingly, In the app that I'm working on I want a black background color for both views in the UISplitViewController. I'd like to change the color of the divider line to white (so that you can see it). Making both background colors black is one way to get rid of (make invisible) the dividing line but that's probably not a solution for most people.
Tested on iOS10 (probably will work on iOS9 too).
splitviewController.view.backgroundColor = UIColor.white
it removes divider. Apparently divider is just a gap between master and detail container.
I looked around for a while, and came to the conclusion that theres no way to do this, other than to create your own custom split view.
Try the MGSplitViewController by Matt Gammell
http://mattgemmell.com/2010/07/31/mgsplitviewcontroller-for-ipad
I may be late here, but I DO have a solution that works. It even works for the iOS 8+ splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModeAllVisible; and seamlessly slides in and out when you press the Full Screen toggle button.
Here is the trick :
first Subclass UISplitViewController.m
In the header add the follwing :
#property (strong, nonatomic) UIView *fakeNavBarBGView;
In the viewDidLoad method add the following code :
CGFloat fakeNavBarWidth = 321; // It is important to have it span the width of the master view + 1 because it will not move when the split view slides it's subviews (master and detail)
CGFloat navbarHeight = self.navigationController.navigationBar.frame.size.height + 20;
self.fakeNavBarBGView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, fakeNavBarWidth, navbarHeight)];
self.fakeNavBarBGView.backgroundColor = [UIColor redColor];
// Add Fake navbar to back of view
[self.view insertSubview:self.fakeNavBarBGView atIndex:0];
// SplitView Controller
UISplitViewController *splitViewController = self;
DetailViewController *detailVC = [navigationController.viewControllers lastObject];
detailVC.fakeNavBarSubView = self.fakeNavBarBGView;
detailVC.SVView = self.view;
In the DetailViewController.h add the following :
#property (strong, nonatomic) UIView *SVView;
#property (strong, nonatomic) UIView *fakeNavBarSubView;
Now here is the final trick : in the DetailViewController.m, add the following in the viewDidLoad method (called every time you click the Master table) :
[self.SVView sendSubviewToBack:self.fakeNavBarSubView];
[self.SVView bringSubviewToFront:self.view];
Run it and watch the magic ;-)
Private API (can cause App Store rejection):
[splitViewController setValue:#0.0 forKey:#"gutterWidth"];
I did this accidentally by setting the backgroundColor property of the first viewController's view - possibly to clearColor, I don't remember now.
UIManager.put("SplitPaneDivider.draggingColor", new Color(255, 255, 255, 0));
