- //比如需要打印当前被调用的方法,可以在一个方法中添加:
- NSLog(@"%@ call",NSStringFromSelector(_cmd));
- //会输出类似
- //2013-01-10 11:25:46.902 TDDataViewer[855:303] applicationDidFinishLaunching: call
- //这样的内容。
- //在cocos2d中,_cmd通常用于定时调用某个函数(schedule)
- //比如下面方法利用_cmd能够不定时地调用某个函数
- -(void) scheduleUpdates {
- // schedule the first update as usual
- [self schedule:@selector(irregularUpdate:) interval:1];
- }
- -(void) irregularUpdate:(ccTime)delta {
- // unschedule the method first [self unschedule:_cmd];
- // I assume you’d have some kind of logic other than random to determine
- // the next time the method should be called
- float nextUpdate = CCRANDOM_0_1() * 10;
- // then re-schedule it with the new interval using _cmd as the selector
- [self schedule:_cmd interval:nextUpdate];
- }
