手势冲突UITableView滑动删除iOS

Question

我的手势识别器有问题。我的目标是实现在我的表格视图中使用滑动删除。但我认为其他手势彼此冲突。我正在使用这个库romaonthego/REFrostedViewController 这是我的汉堡菜单的一个库，这个库有一个pangesture功能。我认为冲突是在手势中。因为当我在另一个项目中运行我的tableview代码时，它正在工作。请帮助，谢谢您。

Answer 1

首先...看看，如果你有这个

- (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...

尝试添加该

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

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

我有一个类似的问题，我最终做的和TonyMkenu类似，但是有更多的认识者认为y OU需要允许：

- (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; 

}

编辑：更新了iOS的11

其他的答案是有帮助的，但对我来说最好的解决办法是应该做的逻辑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; 
} 

这在我的情况下有更好的行为。我还在我的平底锅手势上使用了delaysTouchesBegan = YES。可能有用！

在iOS 11中，希望这可以帮助你。

- (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; 
}
