当UIScrollView滚动时，CADisplayLink停止更新 [英] CADisplayLink stops updating when UIScrollView scrolled

问题描述

标题是相当自我解释，但我有一些动画在由CADisplayLink触发的循环中完成。但是，一旦我滚动UIScrollView我已经添加到我的视图层次结构，动画立即停止，只有当滚动完全停止并停止时再次返回....

$ b

运行显示链接（使用 -addToRunLoop ：forMode：）在另一个线程与另一个运行循环。因此，创建一个新线程，在该线程上创建一个运行循环，并在该线程/运行循环上运行CADisplayLink。

Title is quite self explanatory, but I have some animation being done in a loop triggered by CADisplayLink. However, as soon as I scroll a UIScrollView I have added to my view hierarchy, the animation stops immediately, only to return again when scrolling has completely stopped and come to a standstill....

Anyway to cancel this behaviour?

解决方案

Run the display link (using -addToRunLoop:forMode:) on another thread with another run loop. So create a new thread, create a run loop on that thread, and run the CADisplayLink on that thread/run loop.
