After clicking button make it disabled for a while (XCode)
提问by TomasJ
I'd like to know how can I make a button disable for few seconds after clicking it. I can disable it with code
我想知道如何在单击按钮后禁用几秒钟。我可以用代码禁用它
button.enabled = button.enabled = NO;
button.enabled = button.enabled = NO;
But I'm not sure how it can be done for just few seconds.
但我不确定如何在短短几秒钟内完成。

Use this code:
使用此代码：
double delayInSeconds = 2.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
button.enabled = NO;
});
EDIT: If you want to disable your button first and execute some code later on, do this:
编辑：如果您想先禁用按钮并稍后执行一些代码，请执行以下操作：
button.enabled = NO;
double delayInSeconds = 2.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
//this will be executed after 2 seconds
});
