UIImagePickercontroller取消按鈕在iPad中不顯示

Question

單擊按鈕時，我正在從相冊中保存圖像。 取消相冊后，我在iPad中沒有“取消”按鈕以取消相冊。 選擇任何人從相冊中保存圖像后，它將關閉並將拾取圖像添加到UIImageView。 但是如果沒有從圖庫中選擇圖片，我將無法關閉相冊。 在iPhone中，它正在使用cancel。

-(void)picker:(id)sender{

if ([self->popoverController isPopoverVisible]) {
 [self->popoverController dismissPopoverAnimated:YES];

 } else {
 if ([UIImagePickerController isSourceTypeAvailable:
 UIImagePickerControllerSourceTypeSavedPhotosAlbum])
 {
 imagePicker=[[UIImagePickerController alloc]init];

 imagePicker.delegate = self;

 imagePicker.allowsEditing =NO;

 imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

  self->popoverController = [[UIPopoverController alloc]
 initWithContentViewController:imagePicker];

 self->popoverController.delegate = self;


 CGRect popoverRect = [self.view convertRect:[self.view frame]
 fromView:[self.view superview]];

 popoverRect.size.width = MIN(popoverRect.size.width, 100) ;
 popoverRect.origin.x  = popoverRect.origin.x+10;



 [self->popoverController
 presentPopoverFromRect:popoverRect
 inView:self.view
 permittedArrowDirections:UIPopoverArrowDirectionAny
 animated:YES];

 }



 -(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker{
 //release picker


 //  [picker dismissModalViewControllerAnimated:YES];

 if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {

 [picker dismissViewControllerAnimated:YES completion:nil];
 }else{

 [picker dismissViewControllerAnimated:YES completion:nil];

 if (popoverController != nil) {
 [popoverController dismissPopoverAnimated:YES];
 popoverController=nil;
 }

 }

}



 -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{


 if (popoverController != nil) {
 [popoverController dismissPopoverAnimated:YES];
 popoverController=nil;
 }


 [picker dismissViewControllerAnimated:YES completion:nil];



 }

Answer 1

您將在popoverController中顯示imagePickerController，因此它將沒有“手動取消”按鈕，因為您可以點擊彈出框之外的任何位置以將其關閉。

Answer 2

我以前遇到過這個問題。 請在下面的問題中檢查接受的答案。 它為我工作。

UIPopoverController中的UIImagePickerController在iOS7上未顯示“取消”按鈕
