Mac开发——报错:Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'NSWindow drag regions should only be invalidated on the Main Thread!'
完整报错
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'NSWindow drag regions should only be invalidated on the Main Thread!' terminating with uncaught exception of type NSException
原因
所有AppKit / GUI调用都需要在主线程中进行,无法在其他线程执行。
解决办法
在主线程执行代码,如果该代码在其他子线程当中,则可以用dispatch_async(dispatch_get_main_queue(), ^{})方法调起主线程,将代码写在其中
