[英]NSTimer not repeating from AppDelegate
why would this not repeat when place in appDidFinishLaunching? 放在appDidFinishLaunching中时为什么不重复?
self.ti = [NSTimer timerWithTimeInterval:10. target:self selector:@selector(bounce:) userInfo:nil repeats:YES];
[self.ti fire];
many thanks 非常感谢

I think your bounce
has a wrong signature. 我认为你的
bounce
有一个错误的签名。 It should be 它应该是
- (void)bounce:(NSTimer*)theTimer {
NSLog(@"Here...");
}
You should be using selector(bounce:)
to schedule this method. 您应该使用
selector(bounce:)
来安排此方法。 You should also be calling scheduledTimerWithTimeInterval
instead of timerWithTimeInterval
: 您还应该调用
scheduledTimerWithTimeInterval
而不是timerWithTimeInterval
:
self.ti = [NSTimer
scheduledTimerWithTimeInterval:10.
target:self
selector:@selector(bounce:)
userInfo:nil
repeats:YES];
I'm not sure if it will help, but try using scheduledTimerWithTimeInterval
method. 我不确定它是否有用,但尝试使用
scheduledTimerWithTimeInterval
方法。 An example: 一个例子:
self.ti = [NSTimer scheduledTimerWithTimeInterval:10. target:self selector:@selector(bounce) userInfo:nil repeats:YES];
Hope it helps 希望能帮助到你
