NSTimer没有从AppDelegate中重复 [英] NSTimer not repeating from AppDelegate

问题描述

为什么将其放置在appDidFinishLaunching中时不会重复?

why would this not repeat when place in appDidFinishLaunching?

self.ti = [NSTimer timerWithTimeInterval:10. target:self selector:@selector(bounce:) userInfo:nil repeats:YES];
[self.ti fire];

非常感谢

推荐答案

我认为您的 bounce 签名错误.应该是

I think your bounce has a wrong signature. It should be

- (void)bounce:(NSTimer*)theTimer {
    NSLog(@"Here...");
}

您应该使用 selector(bounce:)安排此方法.您还应该调用 scheduledTimerWithTimeInterval 而不是 timerWithTimeInterval :

You should be using selector(bounce:) to schedule this method. You should also be calling scheduledTimerWithTimeInterval instead of timerWithTimeInterval:

self.ti = [NSTimer
    scheduledTimerWithTimeInterval:10.
                            target:self
                          selector:@selector(bounce:)
                          userInfo:nil
                           repeats:YES];
