一个轻量级的通过Block执行通知回调的对象KVO扩展，整个库一共200行代码。

## Example

To run the example project, clone the repo, and run `pod install` from the Example directory first.

## How to use

* Normally KVO:

```

@interface Observer:NSObject

@end

@implementation Observer

-(void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context

{

	if ([keyPath isEqualToString:@"frame"]){

		NSLog(@"the frame=%@", change[NSKeyValueChangeNewKey]);

    }

}

@end

UIView *view = [UIView new];

Observer *observer = [Observer new];

[view addObserver:observer forKeyPath:@"frame"  options:NSKeyValueObservingOptionNew  context:NULL];

view.frame = CGRectZero;

```

* YSObserver 

```

UIView *view = [UIView new];

[view ys_addObserver:anyObject forKeyPath:@"frame" withBlock:^(id newVal, id OldVal){

	NSLog(@"the frame=%@", newVal);

}];

```
