在iPad上调用image picker

在viewcontroller 头加入委托声明：

UIImagePickerControllerDelegate

UINavigationControllerDelegate

UIPopoverControllerDelegate

 

 

 

在active加入如下代码

UIImagePickerController* picker = [[UIImagePickerController alloc] init]; picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; picker.delegate = self; UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker]; self.popoverController = popover; popoverController.delegate = self; [popoverController presentPopoverFromRect:CGRectMake(100, 100, 200, 300) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES]; //release the popover content [picker release];
