我在每间囚室(实际上使用易懂的电文的Im)内有一份可贵的电文,从中可以看出,每二人中有3个电文在变图像。
问题在于,这些图像只有在没有发生滚动的时候才会改变。
我阅读了一些有关这个问题的问题,我发现有人建议使用NSRunLoop,但在装上外部图像时,使用“UIImage形象Named”和UIImageView集束时,这有利于NSURLConnection。 我宣读的另一项建议是利用国家职业介绍行动,但两者都没有。
NSInvocationOperation *invocation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(changeProgress) object:nil];
[invocation start];
否则,请帮助! 感谢。
一位朋友找到了解决办法,我不得不在不安排时间的情况下创造时间,并在NSRunLoop上加入,这样,法典就是这样:
_timer = [NSTimer timerWithTimeInterval:1.0/3.0 target:self selector:@selector(update:) userInfo:nil repeats:YES];
[[NSRunLoop mainRunLoop] addTimer:_timer forMode:NSRunLoopCommonModes];
你们是否试图这样做?
