开启后，WeakProxy NSTimer定时针失效

[ZC-Hank]

直接使用YYTextWeakProxy 定时器还是失效

self.timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:[YYTextWeakProxy proxyWithTarget:self] selector:@selector(timerEvent1:) userInfo:nil repeats:YES];
// self.timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(timerEvent1:) userInfo:nil repeats:YES];
[[NSRunLoop currentRunLoop] addTimer:self.timer forMode:NSRunLoopCommonModes];

#import <Foundation/Foundation.h>

/**

It can be used to avoid retain cycles, such as the target in NSTimer or CADisplayLink.

sample code:

  YYTextWeakProxy *proxy = [YYTextWeakProxy proxyWithTarget:self];
  _timer = [NSTimer timerWithTimeInterval:0.1 target:proxy selector:@selector(tick:) userInfo:nil repeats:YES];
  }

• (void)tick:(NSTimer *)timer {...}

因为你用了YYTextWeakProxy 弱引用功能，而且他是通过NSProxy转发的，所以没有selector存在的，target 并没有执行invoke，如果你们团队内统一用YYTextWeakProxy，可以关闭JJExceptionGuardNSTimer，这样就不会有问题了
