Ios -[id<；UIGestureRecognitzerDelegate>；GestureRecognitzer:应使用GestureRecognitzer同时识别]调试器中的两个识别器均为零

我有办法

-（BOOL）GestureRecognitor:（UIGestureRecognitor*）GestureRecognitor应与GestureRecognitor:（UIGestureRecognitor*）其他GestureRecognitor同时识别
{
NSLog（@“%@\n%@”、手势识别器、其他手势识别器）；
返回YES；
}

日志记录正常：

发生了什么事？我能解决这个问题吗？

你初始化识别器了吗

UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panView:)];
[panRecognizer setMinimumNumberOfTouches:1];
[panRecognizer setMaximumNumberOfTouches:1];
panRecognizer.delegate = self;
[self.webView addGestureRecognizer:panRecognizer];

这是一个已知的XCode/lldb错误，尚未解决。如果您没有运行xcode 5-dp，您可以返回到gdb，它应该可以工作

Xcode 4.3发行说明：“使用LLDB调试器时，断点中的某些调试器命令和日志表达式会失败，因为Xcode在执行调试器命令或计算日志表达式时使用了错误的帧。如果您知道调试器命令或日志表达式必须相对于哪个线程运行，请添加一个断点操作，将当前帧设置为问题的断点操作之前的相应帧。10426977“

我的参考资料：

是的，当然。方法被调用了一千次。我说，

NSLog

正在打印它们，但它们不在调试器控制台中。你能展示一下初始化手势识别器的代码吗？这很奇怪。你是在方法中使用po吗？你的类没有ivar的同名。

UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panView:)];
[panRecognizer setMinimumNumberOfTouches:1];
[panRecognizer setMaximumNumberOfTouches:1];
panRecognizer.delegate = self;
[self.webView addGestureRecognizer:panRecognizer];
