UIImagePickercontroller取消按钮在iPad中不显示

Question

I'm getting saved images from photo album while clicking button. After dispalying photo album i don't have cancel button in iPad for cancel the photo album. After choosing anyone saved images from photo album then it closing and adding picking image to UIImageView. But without choosing image from gallery i'm not able to close the photo album. In iphone it's working with 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

您将在popoverController中显示imagePickerController，因此它将没有“手动取消”按钮，因为您可以点击弹出框之外的任何位置以将其关闭。
