uiCustomPopover = [[UIPopoverController alloc]  initWithContentViewController:self.TestAppDisplayPopoverViewController];
[uiCustomPopover setPopoverContentSize:CGSizeMake(354.5, 229.5)];
uiCustomPopover.delegate=self;
[uiCustomPopover presentPopoverFromRect:CGRectMake(250,15.0, 1.0, 1.0) inView:someView permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];

以上是我的应用的崩溃日志，我不知道，可能是导致崩溃的原因是什么？是因为UIPopoverController还是因为PresentPopoverFromRect。非常感谢任何形式的帮助。

提前致谢：）

代码已添加......

Answer 1

尝试制作

@property (strong, nonatomic) UIPopoverController *uiCustomPopover;

然后：

self.uiCustomPopover = [[UIPopoverController alloc]  initWithContentViewController:self.TestAppDisplayPopoverViewController];
[self.uiCustomPopover setPopoverContentSize:CGSizeMake(354.5, 229.5)];
self.uiCustomPopover.delegate=self;
[self.uiCustomPopover presentPopoverFromRect:CGRectMake(250,15.0, 1.0, 1.0) inView:someView permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];

那应该有所帮助。我也有同样的问题，比如UIPopoverController在呈现之前已经解除分配或者什么......

由于UIPopoverController，未知的应用程序崩溃了
