2. UITableView走numberOfRowsInSection方法，却不走cellForRowAtIndexPath方法小记.
   解决地址

3. *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIKeyboardTaskQueue waitUntilAllTasksAreFinished] may only be called from the main thread.'
   解决：present放在主线程

4. Failed to load Info.plist from bundle at path ***

   
   奇葩问题1，不是我的错

解决方案：

1. 清空项目 shift+command+k
2. 把app从模拟器中删除
3. 重启模拟器

5. 'UICollectionView must be initialized with a non-nil layout parameter' （UICollectionView初始化时必须指定一个非空的布局对象）

解决方案：UICollectionView只能通过let collectionView = UICollectionView(frame: view.bounds, collectionViewLayout: layout)这种方式创建。我之前是先设置frame，后设置layout都不行

6. Command PhaseScriptExecution failed with a nonzero exit code

解决方案：Clean工程，不行的话重启Xcode。

7. pod导入YYText，在ViewController中使用时就crash崩溃问题。 *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Application windows are expected to have a root view controller at the end of application launch'
   解决地址

8. Main Thread Checker: UI API called on a background thread: -[UIApplication applicationState] PID: 623, TID: 100436, Thread name: com.apple.CoreMotion.MotionThread, Queue name: com.apple.root.default-qos.overcommit, QoS: 0
