在 iPhone 中每 60 秒调用一个方法 [英] calling a method after each 60 seconds in iPhone

问题描述

我已经创建了一个 GKSession 并且当它的对象被创建时，它开始搜索设备的可用性，如

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 {

我想每60秒调用一次这个方法，怎么办?

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

推荐答案

使用 NSTimer

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

每 60.0 秒后，iOS 将调用以下函数

After each 60.0 second , iOS will call the below function

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