             object:nil
             userInfo:dic];
        }
    }
}

如果没有表情符号，此方法可以正常工作，因为此sting只有一个\ emoji，NSJSONSerialization不起作用。有人可以帮我解决这个问题。

Answer 1

问题是您正在对JSON字符串进行硬编码并对其进行更改，不要对您的INSERT INTO time_in(late,time_in) VALUES ('$late,NOW())";字符串进行任何更改，并直接将其转换为JSON。

NSData

Answer 2

试试这个。

将带有表情符号的字符串转换为带有unicode的字符串，如下所示

NSData *data = [strEmoji dataUsingEncoding:NSNonLossyASCIIStringEncoding];
NSString *unicodeString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

如果你想在某个地方展示表情符号，那么你可以转换回表情符号。

NSData *data = [unicodeString dataUsingEncoding:NSUTF8StringEncoding];
NSString *emojiString = [[NSString alloc] initWithData:data encoding:NSNonLossyASCIIStringEncoding];

NSJSONSerialization不使用表情符号
