MRTimer是一个简单的iOS工具，用来计算方法的执行时间。
示例代码：
- (void)viewDidLoad { [super viewDidLoad]; [MRTimer observeSelector:@selector(doSomething) timeIntervalBlock:^(NSTimeInterval interval) { NSLog(@"Time interval for selector: (%@, %f), NSStringFromSelector(doSomething), interval); }];}- (void)doSomething{ [MRTimer observeBegin:MR_SELECTOR]; ... [MRTimer observeEnd:MR_SELECTOR];}
