帮助!
崩溃发生在:
[emtionString replaceCharactersInRange:range withString:imageAndRangeDicArray[i][@"image"]];
当NSMutableAttributedString被attributeString替换时
这是堆栈跟踪:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSConcreteMutableAttributedString _encodingCantBeStoredInEightBitCFString]: unrecognized selector sent to instance 0x7fe8f34f52f0'

最佳答案
emtionString 和 imageAndRangeDicArray[i][@"image"] 是什么类型？
根据文档，该方法需要一个 NSString 作为 withString。
如果您传入 NSAttributedString，则它将不起作用。 (看起来 NSAttributedString 应该是 NSString 的子类，但事实并非如此。)
