NSTimer 不从 AppDelegate 重复

为什么当放置在 appDidFinishLaunching 中时不会重复？

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

非常感谢

我认为你的bounce签名错误。它应该是

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

你应该使用selector(bounce:)安排此方法。你也应该打电话scheduledTimerWithTimeInterval代替timerWithTimeInterval:

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