NSTimer 不会停止
I have this code:
我有这个代码：
[NSTimer scheduledTimerWithTimeInterval:110.0
target:self
selector:@selector(targetMethod:)
userInfo:nil
repeats:YES];
- (void) targetMethod:(NSTimer) timer{
NSLog(@"Hello World");}
in targetMethod I can stop timer with [timer invalidate], but out of this method, How can I stop targetMethod?
在 targetMethod 中，我可以使用 [timer invalidate] 停止计时器，但是在此方法之外，我如何停止 targetMethod？

You can keep your NSTimerin a variable and stop the timer using the invalidatemethod. Like the following:
您可以将NSTimer变量保留在变量中并使用该invalidate方法停止计时器。像下面这样：
NSTimer * myTimer = [NSTimer scheduledTimerWithTimeInterval:110.0
target:self
selector:@selector(targetMethod:)
userInfo:nil
repeats:YES];
[myTimer invalidate];

One way to do it is to create NSTimer *timer; as a global variable so you can have a handle to the timer. Some thing likes this:
一种方法是创建 NSTimer *timer; 作为全局变量，因此您可以拥有计时器的句柄。有些事情是这样的：
NSTimer *timer; //global var
timer = [NSTimer scheduledTimerWithTimeInterval:110.0
target:self
selector:@selector(targetMethod:)
userInfo:nil
repeats:YES];
To stop timer somewhere in the same class:
要在同一班级的某处停止计时器：
[timer invalidate];
