问题 I'm presenting a list of options to the user using an UIAlertController from a UIToolbar with a preferred style of action sheet. When presented, the popover's arrow is cut off and its corners are rounded with two different radii: The code I'm using to present it is straight from the documentation, as far as I see it: UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"" message:@"" preferredStyle:UIAlertControllerStyleActionSheet]; NSArray *actions = @[

问题 I have opened a pop up window on button click. I want to set x and y position of that view. I have tried a lot but can't set it properly. This is my code: -(IBAction)product2_click_h2 { //build our custom popover view UIViewController* popoverContent2 = [[UIViewController alloc] init]; UIView* popoverView2 = [[UIView alloc]initWithFrame:CGRectMake(100,100,200,200)]; popoverView2.backgroundColor = [UIColor greenColor]; UITextView *prod2_info = [[UITextView alloc]initWithFrame:CGRectMake(5,5

问题 First of all, can we talk about iOS 5 here? Or is it still under NDA? If we can't talk about it, just ignore my question. By testing my app with an iPad with iOS 5 installed I discovered a problem with my "modal" popover: This can be closed by tapping outside of it, in other words, it's not modal! I have no idea what I'm doing wrong. A view controller opens the popover with this code: AddProjectViewController *addProjectViewController = [[AddProjectViewController alloc] initWithStyle

I have the delegate but when I tap outside of the popover this method is not called. What can I do? Thanks!! 回答1: Add this line of

问题 I'm displaying a popover in iPad with a UINavigation bar. On the second view, I have a UISearchController that can display a keyboard. The keyboard pushes the popover up, which is fine, however if I now push the 'back' button on the UINavigation bar it dismisses the keyboard which is fine, but the popover doesn't slide back down to its original position. Anyone know how to fix that? Thanks! 回答1: Ok so I actually figured out (I believe) what your question was asking...and just in case anyone

问题 While displaying a popover controller for a second time (after dismissing it and then re-displaying it), I get the following error: Terminating app due to uncaught exception 'NSGenericException', reason: '-[UIPopoverController dealloc] reached while popover is still visible.' The stack trace is only a bunch of hex and the SIGABRT happens at UIApplicationMain every time. Here's the code that the button triggers: - (IBAction)createNewScore:(id)sender { if (self.pc) if (self.pc.popoverVisible)

问题 My goal is to keep same coordinates for a UIPopoverController with just changing arrow offset. So basically i have three buttons touching each of them shows up a popover. When presenting this popover it changes position on the screen, but i do not want that. To be more clear look at screenoshots: 回答1: For my popover I wanted the arrow to be top-left instead of top-center (which is default). I've managed to get the result below (screenshot) by setting the popoverLayoutMargins property of the
