推荐答案
对象不响应 _fastCharacterContents 选择器，因此抛出运行时异常。
An NSData object doesn't respond to a _fastCharacterContents selector, so there's a runtime exception being thrown.
NSString 但是， DOES 有一个带有该名称的私有方法，因此您可能会将 NSData 对象存储到假定为一个 NSString 。
NSString, however, DOES have a private method with that name, so it's likely that you're storing an NSData object into something that is assumed to be an NSString.
