虽然我明白为什么我收到错误
'', 原因：'-[UIPopoverController initWithContentViewController:] 未在 UIUserInterfaceIdiomPad 下运行时调用。'
纠正它变得有点棘手。我的弹出窗口只需要在 ipad 上而不是在 iphone 版本上。我省略了 iphone 的任何代码，但if statement仍然崩溃。. 假设我必须调用 iphone 上的视图以及它的通用应用程序，我只是调用了 nib 中的 nib if iphone statement，但这也不起作用。
- (IBAction)popZs:(id)sender {
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
if ([popoverController isPopoverVisible]) {
[popoverController dismissPopoverAnimated:YES];
} else {
[self->popoverController setPopoverContentSize: CGSizeMake(601, 571)];
[popoverController presentPopoverFromRect:((UIButton *)sender).bounds
inView:sender
permittedArrowDirections:UIPopoverArrowDirectionUp
animated:YES];
}
}
else {
/////using iPhone/////not sure how to handle this spart
zsTablePop *pop = [[zsTablePop alloc] init];
pop.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[pop presentModalViewController:pop animated:YES];
}
即使我正在使用，仍然会出现相同的错误if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
