问题 I'm creating some UIButton s programmatically in a loop but I'm having some problem with setting the background color of the button. The color of the button always shows up as white. But works fine with I'm only using 2 colors in the backgroundcolor. Eg : red : 255 green:0 blue :200 Here is the code I'm using to add the button. UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(80, 20 + (i*75), 200, 75); button.layer.cornerRadius = 10; button.layer

问题 This question already has answers here : How to stop unwanted UIButton animation on title change? (23 answers) Closed 3 years ago . I am using a NSTimer to update a UIButton 's title every second. It works but the text in the title blinks (animates to alpha 0 and back) automatically. I tried to use button.layer.removeAllAnimations() with no luck, and no exceptions, so QuartzCore seems to be correctly linked. Current non-working paranoid code: UIView.setAnimationsEnabled(false) UIView

问题 So, I've begun working on a project in SpriteKit, and I'm hoping to be able to implement a "main menu" scene with a few buttons. One would go to a level select screen, one would be options, etc. Then from the level select screen, there would be several other buttons that when selected would start the game and load the selected level. My question is this: how should the project be set up? Should each screen (level select, main menu, options) be its own scene and have one main view controller?

问题 I am trying to create - HeaderView which is subclass of UIView, it contains a close button and a title label. class HeaderView: UIView { private var titleLabel: UILabel! private var closeButton: UIButton! } I don't want to add self as target of closeButton action but want to set myViewController as its target, moreover I want HeaderView class to be reusable. So I declared a protocol: protocol CloseViewProtocol { func closeViewAction(sender: UIButton!) } And declared a variable like this:

问题 I I have an UIButton in my objective-c application. My button was modified adding text and image like: - (void)centerButtonAndImageWithSpacing:(CGFloat)spacing { CGFloat insetAmount = spacing / 2.0; self.imageEdgeInsets = UIEdgeInsetsMake(0, -insetAmount, 0, insetAmount); self.titleEdgeInsets = UIEdgeInsetsMake(0, insetAmount, 0, -insetAmount); self.contentEdgeInsets = UIEdgeInsetsMake(0, insetAmount, 0, insetAmount); } And then I add the image with this code: [self.myButton setImage:[UIImage

问题 I know this issue is already been asked few times in SO. Despite trying those out, I am still unable to solve my problem. I am using a UITableView inside a UIViewController.
