ViewController A you can write: – (IBAction)done:(UIStoryboardSegue *)segue { // Optional place to read data from closing controller } ViewController B … Read more
Fast fix: 1) Set fonts as System for size classes 2) Subclass UILabel and override “layoutSubviews” method like: – (void)layoutSubviews { [super layoutSubviews]; // Implement font logic depending on screen size if ([self.font.fontName rangeOfString:@”bold” options:NSCaseInsensitiveSearch].location == NSNotFound) { NSLog(@”font is not bold”); self.font = [UIFont fontWithName:@”Custom regular Font” size:self.font.pointSize]; } else { NSLog(@”font is bold”); … Read more
Check it out: UILabel *label = … label.userInteractionEnabled = YES; UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelTap)]; [label addGestureRecognizer:tapGesture]; The trick is to enable user interaction.
I had the same problem. But I have resolved it. Yes, you can disable auto layout at runtime for a specific UIView, instead of disabling it for the whole xib or storyboard which is set by default in Xcode 4.3 and later. Set translatesAutoresizingMaskIntoConstraints to YES, before you set the frame of your subview: self.exampleView.translatesAutoresizingMaskIntoConstraints … Read more
The storyboard ID is a String field that you can use to create a new ViewController based on that storyboard ViewController.

Sample code to set the rightbutton on a NavigationBar. UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@”Done” style:UIBarButtonItemStyleDone target:nil action:nil]; UINavigationItem *item = [[UINavigationItem alloc] initWithTitle:@”Title”]; item.rightBarButtonItem = rightButton; item.hidesBackButton = YES; [bar pushNavigationItem:item animated:NO]; But normally you would have a NavigationController, enabling you to write: UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@”Done” style:UIBarButtonItemStyleDone target:nil action:nil]; self.navigationItem.rightBarButtonItem = … Read more
Go to the File inspector in interface builder, and untick “Use Auto Layout”.
This is not a bug, this is a consequence of how Xcode processes storyboard files. I am writing a diff and merge program for storyboard files (GitHub link) and I have spent hours analyzing the storyboard files logic and how Xcode processes it. This is what I discovered: Why do weird changes occur in storyboard … Read more
Do the following steps to resolve the issue In Storyboard, select any view, then go to the File inspector. Uncheck the “Use Size Classes”, you will ask to keep size class data for: iPhone/iPad. And then Click the “Disable Size Classes” button. Doing this will make the storyboard’s view size with selected device.
This will make exactly what you were expecting: Objective-C: [myButton.titleLabel setTextAlignment:UITextAlignmentCenter]; For iOS 6 or higher it’s [myButton.titleLabel setTextAlignment: NSTextAlignmentCenter]; as explained in tyler53’s answer Swift: myButton.titleLabel?.textAlignment = NSTextAlignment.Center Swift 4.x and above myButton.titleLabel?.textAlignment = .center
