手勢衝突UITableView滑動刪除iOS

Question

我的手勢識別器有問題。我的目標是實現在我的表格視圖中使用滑動刪除。但我認爲其他手勢彼此衝突。我正在使用這個庫romaonthego/REFrostedViewController 這是我的漢堡菜單的一個庫，這個庫有一個pangesture功能。我認爲衝突是在手勢中。因爲當我在另一個項目中運行我的tableview代碼時，它正在工作。請幫助，謝謝您。

Answer 1

首先...看看，如果你有這個

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    // Return NO if you do not want the specified item to be editable. 
    return YES; 
} 

和第二...

嘗試添加該

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { 

    if ([gestureRecognizer.view isKindOfClass:[UITableView class]]) { 
     return YES; 
    } else { 
     return NO; 
    } 
}

我有一個類似的問題，我最終做的和TonyMkenu類似，但是有更多的認識者認爲y OU需要允許：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { 

if (otherGestureRecognizer.delegate == self) 
    return NO; 

//if otherGestureRecognizer is swipe to delete from a UITableView cancel slide menu recognizers 

if ([[otherGestureRecognizer.view class] isSubclassOfClass:[UITableView class]]) 
{ 
    NSLog(@"Allow1 %@", [otherGestureRecognizer description]); 

    return YES; 
} 

if([[otherGestureRecognizer.view class] isSubclassOfClass:[UITableViewCell class]] || 
[NSStringFromClass([otherGestureRecognizer.view class]) isEqualToString:@"UITableViewCellScrollView"] || 
[NSStringFromClass([otherGestureRecognizer.view class]) isEqualToString:@"UITableViewWrapperView"]) 
{ 
    NSLog(@"Allow&Disable %@", [otherGestureRecognizer description]); 

    if(gestureRecognizer.delegate == self) 
    {//cancel the slide menu recognizer 

     gestureRecognizer.enabled = NO; 
     gestureRecognizer.enabled = YES; 
    } 

    return YES; 
} 

NSLog(@"Deny %@", [otherGestureRecognizer description]); 
return NO; 

}

編輯：更新了iOS的11

其他的答案是有幫助的，但對我來說最好的解決辦法是應該做的邏輯shouldRequireFailureOfOtherGesture像所以：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer 
shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer 
{ 
    if (gestureRecognizer == self.pan) { 
     return YES; 
    } 
    return NO; 
} 

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRequireFailureOfGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer 
{ 
    if (gestureRecognizer == self.pan) { 

     // iOS 10 
     if ([NSStringFromClass([otherGestureRecognizer.view class]) isEqualToString:@"UITableViewWrapperView"]) { 
      return YES; 
     } 
     // iOS 11 
     else if ([otherGestureRecognizer isMemberOfClass:[UIPanGestureRecognizer class]] && [otherGestureRecognizer.view isKindOfClass:[UITableView class]]) { 
      return YES; 
     } 
    } 
    return NO; 
} 

這在我的情況下有更好的行爲。我還在我的平底鍋手勢上使用了delaysTouchesBegan = YES。可能有用！

在iOS 11中，希望這可以幫助你。

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { 
    if ([[otherGestureRecognizer.view class] isSubclassOfClass:[UITableView class]]) { 
     if ([otherGestureRecognizer isKindOfClass: [UIPanGestureRecognizer class]]) { 
      UIPanGestureRecognizer *otherPan = (UIPanGestureRecognizer *)otherGestureRecognizer; 
      CGPoint translation = [otherPan translationInView:otherGestureRecognizer.view]; 
      return translation.x < 0; 
     } 
    } 
    return NO; 
}
