KMHookBlock

中文简介：

利用oc runtime的swizzle selector方法进行了block回到封装，让你像KVO观察一个属性变化一样，去观察任何一个selector的调用前和调用后的变化，我称之为KVS

English introduction:

objective-c runtime hook selector using block,like `KVO` to `KVS`. in the KMHookBlock,you can hook any select for a class as you want!

Example：

#import "NSObject+kmHookBlock.h"
TestViewController *testHook;
//we want to hook testhook viewWillAppear selector
//just code like this:
[testHook hookSelectorWithBlock:PAIR_LIST {
        @selector(viewWillAppear:),
        BLOCK_CAST ^void (id slf,BOOL animated) {
            NSLog(@"hook befor viewWillAppear");
            performSuperSelector(slf, @selector(viewWillAppear:), void,animated);
            NSLog(@"hook after viewWillAppear");
        },
        NIL_PAIR}];
