objective-c - 从 UIGestureRecognizer 中排除表格以隐藏键盘

Question

当用户点击文本字段之外时，我使用 UIGestureRecognizer 来放弃键盘。这工作没有问题，我已经成功排除了 3 个按钮，但现在我已经在页面中添加了 2 个表格，我找不到将它们从 shouldReceiveTouch 中排除的方法:

这是相关代码:

- (void)viewDidLoad
{
.....
UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideKeyboard)];
[[self view] addGestureRecognizer:gestureRecognizer];
[gestureRecognizer setDelegate:self];
}

- (void)hideKeyboard
{
[tradeQuantity resignFirstResponder];
[tradeSymbol resignFirstResponder];
[limitPrice resignFirstResponder];
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{        
if (touch.view == placeTradeButton)
{
    return NO;
} else if (touch.view == resetValuesButton)
{
    return NO;
} else if (touch.view == refreshDataButton)
{
    return NO;
} else if (touch.view == secHoldingsTable)
{
    return NO;
} else if (touch.view == tradeTicketsTable)
{
    return NO;
}
return YES;
}

如何排除表格？

Answer 1

我还没有找到问题的答案，但我确实找到了一种可以满足我需要的解决方法。我没有尝试找出如何排除表，而是做了相反的事情。

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{            
if (touch.view == [self view])
{
    return YES;
}
return NO;
}
