问题描述

UIScrollView(或其派生类)正在滚动时,似乎所有正在运行的 NSTimers 都会暂停,直到滚动完成.

While a UIScrollView (or a derived class thereof) is scrolling, it seems like all the NSTimers that are running get paused until the scroll is finished.

有没有办法解决这个问题?线程?优先级设置?有什么事吗?

Is there a way to get around this? Threads? A priority setting? Anything?
