在iPhone中每60秒后调用一次方法(calling a method after each 60 seconds in iPhone)

在iPhone中每60秒后调用一次方法(calling a method after each 60 seconds in iPhone)

我创建了一个GKSession，创建它的对象后，它开始搜索设备的可用性，如

- (void)session:(GKSession *)session peer:(NSString *)peerID didChangeState:(GKPeerConnectionState)state {

我想在每60秒后调用一次该方法，我该怎么办？

I have created an GKSession and as its object is created, it starts search for availability of devices, as

- (void)session:(GKSession *)session peer:(NSString *)peerID didChangeState:(GKPeerConnectionState)state {

I want to call this method after each 60 seconds, what should I do?

最满意答案

使用NSTimer

NSTimer* myTimer = [NSTimer scheduledTimerWithTimeInterval: 60.0 target: self selector: @selector(callAfterSixtySecond:) userInfo: nil repeats: YES];

每隔60.0秒后，iOS会调用下面的函数

-(void) callAfterSixtySecond:(NSTimer*) t { NSLog(@"red"); }

Use NSTimer

NSTimer* myTimer = [NSTimer scheduledTimerWithTimeInterval: 60.0 target: self selector: @selector(callAfterSixtySecond:) userInfo: nil repeats: YES];

After each 60.0 second , iOS will call the below function

-(void) callAfterSixtySecond:(NSTimer*) t { NSLog(@"red"); }
