Cheers EDIT: Just to make things clear Im not sure if this makes a difference but i have my main menu screen, then iam doing the following with an enter button. UIViewController *controller = [

问题 I have added a subview which contains a UIButton control. This subview is added to its superview programatically. I need to perform an action when this button is tapped, but since it's contained within its own subview, I can't hook an IBAction up to the view controller in order to push another view controller. Is there an easy way to detect that the button is tapped and call a method within its super view? 回答1: You can do everything programmatically: [buttonName addTarget:self action:

问题 I'm loading two different views with this IBActions - (IBAction)showFirstView:(id)sender{ theDetailViewController = [DetailViewController new]; [theDetailViewController initWithNibName:@"DetailView" bundle:nil]; NSView *splitRightView = [[theSplitView subviews] objectAtIndex:1]; NSView *aDetailView = [theDetailViewController view]; [aDetailView setFrame:[splitRightView bounds]]; [aDetailView setAutoresizingMask:(NSViewWidthSizable | NSViewHeightSizable)]; [splitRightView addSubview

问题 I have a collection view, and added a UIView below it. The cells shows up on top of it, but they aren't selectable. How can I make them selectable again?

问题 Basically i wanted to implement a popup UIView so i followed what was posted here POP-UP UIView "IMDB App" style This works very well. However i have one query. My main view is a tableView. so when a view is popped up i disable scrolling in the table. Now when the popup subView is removed, i need to re-enable scrolling. How do i achieve that? i can't use willRemoveFromSuperview because the popup view is loading a different NIB altogether. Should i use Notifications? hope i was clear with

问题 i am getting json data into uiwebview(which is added through storyboard) and if the json data is empty i am adding a subview(which is added programatically).and in that subview i am adding a label. when i run it i can see the subview and the label but its size is big, so it goes out of the subview.

问题 When I add a subview below a UICollectionView, sometimes the subview shows up above the UICollectionView cells. Here is the subview insertion code: [self.collectionView insertSubview:self.garmentView atIndex:0]; Not sure if I'm not following a best practice or otherwise missing something obvious. Any assistance appreciated. ** Edit ** It might be worth noting that this only happens in landscape, when the rightmost cell is zoomed in. 回答1: I think self.garmentView.layer.zPosition = -1 [self

问题 My problem is the following: I have a view and to that view I add 3 subViews( view1 , view2 , view3 ) in that order. The views slightly overlap. I want to bring the first view to the top but I just can't get it to work. I tried adding the views with insertSubview:atIndex: and giving view1 a larger index and I tried using addSubview: and then bringSubviewToTop but nothing seems to work. Any ideas? P.S. I can't add the views in a different order. They have to be added in this order. 回答1:

问题 So I've got a quick question here... I've got an instance of a view controller object, lets call it viewCon1 , and it has several subview's placed on it each with unique properties. Lets call them sub1 , sub2 , and sub3 . Now, I add each of these subviews programatically doing something to the extent of: //create the subviews TaskUIButton *sub1 = [[TaskUIButton alloc] init]; TaskUIButton *sub2 = [[TaskUIButton alloc] init]; TaskUIButton *sub3 = [[TaskUIButton alloc] init]; //add them to

问题 I have created a UIStackView in IB which has the distribution set to Fill Equally. I am looking to get the frame for each subView but the following code always returns (0, 0, 0, 0). class ViewController: UIViewController { @IBOutlet weak var stackView: UIStackView! override func viewDidLoad() { super.viewDidLoad() let pView = UIView() let sView = UIView() pView.backgroundColor = UIColor.red sView.backgroundColor = UIColor.orange stackView.addArrangedSubview(pView) stackView.addArrangedSubview
