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>

NS_ASSUME_NONNULL_BEGIN

/** A proxy used to hold a weak object. It can be used to avoid retain cycles, such as the target in NSTimer or CADisplayLink.

sample code:

@implementation MyView { NSTimer *_timer; }

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

• (void)tick:(NSTimer )timer {...} @end / @interface YYTextWeakProxy : NSProxy

/* The proxy target. / @Property (nullable, nonatomic, weak, readonly) id target;

/** Creates a new weak proxy for target.

@param target Target object.

@return A new proxy object. */

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
