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 fire];

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];
