runtime框架 Aspects 类方法使用

// NSString* nameClass = NSStringFromClass(MBProgressHUD.class);
// Class catMetal = objc_getMetaClass([nameClass UTF8String]);
// [catMetal aspect_hookSelector:@selector(showHUDAddedTo:animated:) withOptions:AspectPositionInstead usingBlock:^(id aspectInfo,UIView *view,BOOL bo){
// NSLog(@"%@ 对象的viewDidLoad调用了",aspectInfo.instance);
//
//
// int64_t delayInSeconds = 1.0;
//
// // 延迟的时间
// // 调用方法原来的实现.
//

// NSInvocation *invocation = aspectInfo.originalInvocation;

//
// //[NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(boom:) object:nil];

// unsigned int count;
// Method *methods = class_copyMethodList([MBProgressHUD class], &count);
