后台返回了
result--{
messages = "<null>";
result = "{\"address\":\"\U9e93\U8c37\U4f01\U4e1a\U5e7f\U573ac1\U680b103\",\"articleId\":1388,\"articleNumber\":1,\"contacts\":\"\U674e\U5c0f\U59d0\",\"contactsPhone\":\"18207325127\",\"content\":\"<p style=\\\"font-size:14px;font-family:simsun;color:#333333;background-color:#FFFFFF;\\\">
这种恶心的数据，这是转过一次了的数据，有时候我使用以下方式再转一次就可以解决：
NSString *str = result[@"result"];
NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *content = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
但是 有时候莫名其妙的又崩溃了，后来找了很久，加了一个去掉不规则字符的方法 removeUnescapedCharacter:
NSString *str = result[@"result"];
str = [NSString removeUnescapedCharacter:str];
NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *content = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
具体的就是，我是直接就加在了 NSString 的方法里的：
+(NSString *)removeUnescapedCharacter:(NSString *)inputStr
{
NSCharacterSet *controlChars = [NSCharacterSet controlCharacterSet];//获取那些特殊字符
NSRange range = [inputStr rangeOfCharacterFromSet:controlChars];//寻找字符串中有没有这些特殊字符
if (range.location != NSNotFound)
{
NSMutableString *mutable = [NSMutableString stringWithString:inputStr];
while (range.location != NSNotFound)
{
[mutable deleteCharactersInRange:range];//去掉这些特殊字符
range = [mutable rangeOfCharacterFromSet:controlChars];
}
return mutable;
}
return inputStr;
}
PS: 建议后台处理好。。
