下面是我用来显示弹出窗口的一些代码。第一次调用弹出窗口时会显示。第二次调用它失败并出现“EXE_BAD_ACCESS”错误。它在“self.myTextPopOver = pop;”行上失败 如果我注释掉 [pop release] 行，一切正常，但这意味着我正在泄漏内存。
// Popover Text
- (IBAction)popoverText
{
// Create a popover object
setTextPopOver *setTX = [[setTextPopOver alloc] init];
// Create a UIPopover controller based on a setTextPopOver object
UIPopoverController *pop = [[UIPopoverController alloc] initWithContentViewController:setTX];
// Set self as the delegate
setTX.delegate = self;
// Set the mySelectColorView to PopOver Controller
self.myTextPopOver = pop;
[pop release];
// Present the Popover
[self.myTextPopOver presentPopoverFromRect:titleBack.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:true];
[self.myTextPopOver setPopoverContentSize:setTX.view.frame.size];
[setTX release];
}
