调用一次计时器方法: myTimer = [NSTimer scheduledTimerWithTimeInterval:1.5 target:self selector:@selector(scrollTimer) userInfo:nil repeats:NO]; //不重复,只调用一次.timer运行一次就会自动停止运行 重复调用计时器方法: 注意:将计数器的repeats设置为YES的时候,self的引用计数会加1.因此可能会导致self(即viewController)不能releas…

iOS 中的 NSTimer NSTimer fire 我们先用 NSTimer 来做个简单的计时器,每隔5秒钟在控制台输出 Fire .比较想当然的做法是这样的: @interface DetailViewController () @property (nonatomic, weak) NSTimer *timer; @end @implementation DetailViewController - (IBAction)fireButtonPressed:(id)sender { _ti…

首先看iOS的, Scheduling Timers in Run Loops A timer object can be registered in only one run loop at a time, although it can be added to multiple run loop modes within that run loop. There are three ways to create a timer: Use the scheduledTimerWithTimeI…
