大佬教程收集整理的这篇文章主要介绍了iphone – iPad中的异常,UIImagePickerController必须通过UIPopoverController显示，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
-(IBAction) showCameraUI {
BOOL hasCamera = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera];
UIImagePickerController* picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = hasCamera ? UIImagePickerControllerSourceTypeCamera : UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:picker animated:YES];
}
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[picker dismissModalViewControllerAnimated:YES];
UIImage* image = [info objectForKey:UIImagePickerControllerOriginalImage];
UIImage *yourImageView = image;
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController*)picker
{
[picker dismissModalViewControllerAnimated:YES];
}
但它显示这个例外.有没有人知道为什么在执行函数showCameraUI的最后一行之后显示这样的异常.
UIStatusBarStyleBlackTranslucent is not available on this device. 2013-02-07 10:06:06.976 CaptureImage[460:c07] *** Terminating app due to uncaught exception 'NSInvalidArgumentException',reason: 'On iPad,UIImagePickerController must be presented via UIPopoverController'
例如：
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) { UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker]; [popover presentPopoverFromRect:self.view.bounds inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; self.popover = popover; } else { [self presentModalViewController:picker animated:YES]; }
编辑：如@rmaddy所述,相机可以以模态显示.当sourceType为UIImagePickerControllerSourceTypePhotoLibrary时,上述适用.
