Xcode编译错误和警告汇总(持续更新中)

Error：Cannotassignto'self'outsideofamethodintheinitfamily

mysolution:

如果你的方法是一个初始化方法，则方法名必须用“init”开始，或者，你也可以把方法改为一个类方法，返回一个单例对象，我的问题方法如下：

-(id)initwithPage:(unsigned)pageNum {...}

我把它改为：

-(id)initwithPage:(unsigned)pageNum {...}

我的问题就解决了。

Error：CouldnotloadNIBinbundlewithnameXXX

mysolution:

因为我是用Storyboard，但是却用ViewController的方法加载，所以出错了，改为：

UIStoryboard *sboard = [UIStoryboard storyboardWithName:@"StoryboardFileName" bundle:nil];
YourViewController *vc1 = [sboard instantiateInitialViewController];

Error：Terminatingappduetouncaughtexception'NSUnknownKeyException',reason:'[<ViewController0x7d90880>setValue:forUndefinedKey:]:thisclassisnotkeyvaluecoding-compliantforthekeycurrentTime.'

mysolution:

选中'currentTime'控件所在的storyboard（或nib），点击'currentTime'控件，storeboard左侧的ViewControllerScene中的对应控件也会选中，在Scene选中控件中右键弹出窗口查找删除无效的ReferencingOutlets连接，问题解决，

原来是我把NSMutableDictionary错写成NSMutableArray，包括相应的方法调用，改过来就好了,
