我添加了一个NSTimer,通过将操作设置为隐藏NO
来显示我的费率按钮NSMethodSignature *sgn = [self methodSignatureForSelector:@selector(onTick:)];
NSInvocation *inv = [NSInvocation invocationWithMethodSignature: sgn];
[inv setTarget: self];
[inv setSelector:@selector(onTick:)];
NSTimer *t = [NSTimer timerWithTimeInterval: 10.0
invocation:inv
repeats:YES];
NSRunLoop *runner = [NSRunLoop currentRunLoop];
[runner addTimer: t forMode: NSDefaultRunLoopMode];
然后
-(void)onTick:(NSTimer *)timer {
_Rateapp1.hidden = NO;
_ratebomb.hidden = NO;
_ratelab1.hidden = NO;
}
但是如何让按钮重新显示为YES?
答案 0 :(得分:0)
假设您的目标是在每次定时器关闭时切换按钮的显示,您只需执行以下操作:
- (void)onTick:(NSTimer *)timer {
_Rateapp1.hidden = !_Rateapp1.hidden;
_ratebomb.hidden = !_ratebomb.hidden;
_ratelab1.hidden = !_ratelab1.hidden;
}
您可以用以下内容替换所有计时器创建代码:
NSTimer *t = [NSTimer scheduledTimerWithTimeInterval:10.0 target:self selector:@selector(onTick:) userInfo:nil repeats:YES];
无需调用或运行代码。我还建议您保留对计时器的引用,以便在需要时使计时器无效(停止)。
