错误信息:
Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (Unescaped control character around character 135.) UserInfo=0x170e79d00 {NSDebugDescription=Unescaped control character around character 135.}
如何处理
最关键的地方:
-(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;
}
举例:
NSString *responseString = [NSMutableString stringWithString:[request responseString]];
responseString =[self removeUnescapedCharacter:responseString];
NSData *jsonData = [responseString dataUsingEncoding:NSUTF8StringEncoding];
NSError *error;
NSDictionary * dic = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];
