使用 Option/Alt 键在 iOS 模拟器上模拟捏合

有人在 UITableView 上的 iOS 模拟器中捏合时遇到过问题吗？我有这段代码：

UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(handlePinch:)];
[self.tableView1 addGestureRecognizer:pinch];
[pinch release];

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTouch:)];
[self.tableView1 addGestureRecognizer:tap];
[tap release];

在我的 viewDidLoad 方法中。在我的handlePinch: 和handleTap: 方法中，我只是简单地使用NSLog(@"pinched") 或@"tapped"。水龙头可以工作，但捏合却不起作用。模拟器中是否存在错误，或者我没有为 UITableView 正确模拟它？（按住两个圆圈的 option 键，单击鼠标，然后拖动以模拟捏合）

编辑：我为 tableView 选择了 multiTouchEnabled，但它无法识别捏合操作。但是，如果我更改外部容器 UIView 并将捏手势添加到 UIView，那么它似乎可以工作。但我不认为如果外部 UIView 没有根据文档寻找捏手势，它就不应该起作用。

Has anyone had problems with pinching in the iOS simulator on a UITableView? I have this code:

UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(handlePinch:)];
[self.tableView1 addGestureRecognizer:pinch];
[pinch release];

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTouch:)];
[self.tableView1 addGestureRecognizer:tap];
[tap release];

in my viewDidLoad method. In my handlePinch: and handleTap: methods, I simply NSLog(@"pinched") or @"tapped". The tap works, but the pinching does not. Is there a bug in the simulator, or am I not simulating it correctly for UITableView? (hold option key for the two circles, click on the mouse, then drag to simulate pinching)

Edit:
I selected multiTouchEnabled for the tableView and it does not recognize the pinch. However if I change the outer container UIView and add the pinchgesture to the UIView, then it seems to work. But I don't think that it shouldn't work if the outer UIView is not looking for the pinchgesture according to the documentation.
