推荐答案

您可以创建和计划 NSTimer 在给定的时间间隔上调用您的方法。特别参见以下便利创建方法：

You can create and schedule an instance of NSTimer to call your method on a given time interval. See in particular the following convenience creation method:

+ (NSTimer *)scheduledTimerWithTimeInterval:(NSTimeInterval)seconds target:(id)target selector:(SEL)aSelector userInfo:(id)userInfo repeats:(BOOL)repeats
