推荐答案

好吧，异常原因把问题抛之脑后；您应该在主线程上运行此代码.尝试使用 dispatch_sync 或 dispatch_async 封闭视图创建和笔尖加载，并使用 dispatch_get_main_queue() 传递主队列.

Well, the exception reason gives the problem away; you should run this code on the main thread. Try enclosing the view creation and nib loading using dispatch_sync or dispatch_async and passing the main queue using dispatch_get_main_queue().
