[self presentModalViewController:myImagePicker animated:YES];

但是显示错误

如何在我的基于ipad的应用程序中添加UIImagePickerController控制器以显示多个images.can任何一个为我提供了一个很好的方法。

Answer 1

这样做。当您点击按钮操作中的按钮时，请调用此方法。

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];


    }

}
