问题 I'm trying to implement popover like that: I've spent quite a lot of time trying to customize UIPopoverController and UIPopoverBackgroundView . As I understand my task is impossible with public API for popovers. It is possible: To use small image with fixed corners and stretchable center, in that case I'll have stretched stripes on the side. And also I'll have image "under" the arrow. Fill border with stripes, but in that case I don't have rounded corners. I also have annoying inner shadow

问题 I don't want the drop shadow when the UIPopoverController's view appears. Is there a way to remove this drop shadow look? 回答1: Not straight forward, but since iOS 5, you can make your own custom popover background using UIPopoverBackgroundView. See the answer for this question: Using UIPopoverBackgroundView class. It's pointing to a good tuto. Then, in the initWithFrame of your UIPopoverBackgroundView implementation, you can use a clearColor for the drop shadow. Using offset and radius did

问题 Simple: A view, i present a UIPopoverController in a CGRect using presentPopoverFromRect... and neither the arrow or the popover frame appear even near to the coordinates i asked for in the rect i passed into. Any clues? I've been trying to figure out this by myself but am giving up. Here is the code: if(!myContentController){ myContentController = [[MyContentController alloc] initWithNibName:myNibName bundle:[NSBundle mainBundle]]; // This works pretty well. actually when i show the popover

问题 I am trying to show an (AlertController) Action sheet. But I am getting this waning in console " <_UIPopoverBackgroundVisualEffectView 0x7fd65ef76ec0> is being asked to animate its opacity. This will cause the effect to appear broken until opacity returns to 1.

问题 In my Popover controller, i'm having a table view. On selection of a cell, I want to hide the pop over. How can I achieve it. 回答1: In Header file of Root view controller: @property (strong, nonatomic) UIStoryboardPopoverSegue* popSegue; In the implementation file: - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if( [[segue identifier] isEqualToString:@"popover"] ) { NSLog(@"%@",[segue destinationViewController]); self.popSegue = (UIStoryboardPopoverSegue*)segue; [[segue

问题 Apple's documentation for the UIActionSheet is causing me confusion. First off, in the iPad Human Interface Guidelines, it says : To learn more about using an action sheet in your code, see “Using Popovers to Display Content” in iPad Programming Guide. But then in the "Using Popovers to Display Content" section, it doesn't mention Action Sheets at all! Am I missing something here? http://developer.apple.com/library/ios/#documentation/General/Conceptual/iPadHIG/UIElements/UIElements.html#/

问题 I am making custom popover by subclassing UIPopoverBackgroundView (using this tutorial) and presenting it by using UIPopoverController. Unfortunately as soon as I specify custom popoverBackgroundViewClass the native dimmed background disappears.
