当我更改时间间隔的值时,如何更新我的NSTimer [英] How can I update my NSTimer as I change the value of the time interval
问题描述
我已经实现了 NSTtimer
并且它运行良好。我还将时间间隔参数连接到 UISlider
,用于 iPhone
。但是,当我更改它的值时, NSTimer
仍然以原始时间间隔运行,它不会更新。我如何实现 NSTimer
并让它改变它的时间间隔,因为我的 UISlider
的值发生了变化。以下是我用于 NSTimer
的行。
I have an NSTtimer
implemented and it's working fine. I also have the time interval argument connected to a UISlider
for the iPhone
. However when I change it's value the NSTimer
is still running at the original time interval it does not get updated. How can I implement an NSTimer
and have it change it's time interval as the value of my UISlider
changes. Below is the line I am using for the NSTimer
.
[NSTimer scheduledTimerWithTimeInterval:mySlider.value
target:self
selector:@selector(myMethod)
userInfo:nil
repeats:YES];
我希望它能够使用 UISlider的值不断更新它的时间间隔
。
推荐答案
你不能害怕。使其无效:
You can't I'm afraid. Invalidate it with:
[myTimer invalidate];
然后使用新时间创建一个新的。您可能还必须先将其设置为nil。
Then create a new one with the new time. You may have to set it to nil first as well.
myTimer = nil;
myTimer = [NSTimer scheduledTimerWithTimeInterval:mySlider.value
target:self
selector:@selector(myMethod)
userInfo:nil
repeats:YES];
