Answer 1

是否這樣做。當你點擊按鈕動作中的按鈕時，請調用它。

UIActionSheet *photoActionSheet = [[UIActionSheet alloc] initWithTitle:@"" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Take Photo", @"Choose Existing",nil]; 

     [photoActionSheet showFromRect:CGRectMake(315, 355, 10, 10) inView:self.view animated:YES]; 

Answer 2

#pragma mark UIActionSheetDelegate methods 

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{ 
    imgPicker.delegate = self; 


    if(buttonIndex == 0){ 

      if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){ 
       imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera; 
       [self presentModalViewController:imgPicker animated:YES]; 

     } 


    else if(buttonIndex == 1){ 


      imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
      [self presentModalViewController:imgPicker animated:YES]; 


    }
