如何在UIImagePickerController中獲取發件人按鈕標籤/名稱/ ID - didFinishPickingMediaWithInfo？

Question

有人可以指導我在下面的方法中獲取sender button Tag/Name/ID嗎？

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

// I Want to get the sender button reference here 

} 

Answer 1

您可以使用picker.view.tag來識別UIImagePickerController類型。每當您調用UIImagePicker時，您都可以設置其視圖的標籤。

我已經使用相同的識別不同的圖像選擇器。

編輯

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init]; 
imagePickerController.allowsEditing = YES; 
imagePickerController.delegate = self; 
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
imagePickerController.view.tag = 5;//set the tag here 

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editingInfo 
{ 
    NSLog(@"%d",picker.view.tag); 
} 

你會得到變量值wahtever你會設置。

試試這個

-(IBAction)ownMethod:(id)sender 
{ 
    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init]; 
    imagePickerController.allowsEditing = YES; 
    imagePickerController.delegate = self; 
    imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
    **imagePickerController.view.tag = [sender tag];//set the tag of button to picker tag ** 
    [self presentViewController:imagePickerController animated:YES completion:nil]; 
}
