NSJSONSerialization iOS自带解析json

特殊字符转义

//特殊字符转化

+(NSString *)JSONString:(NSString *)aString {

NSMutableString *s = [NSMutableString stringWithString:aString];

// [s replaceOccurrencesOfString:@""" withString:@""" options:NSCaseInsensitiveSearch range:NSMakeRange(0,[s length])];

// [s replaceOccurrencesOfString:@"/" withString:@"/" options:NSCaseInsensitiveSearch range:NSMakeRange(0,[s length])];

[s replaceOccurrencesOfString:@"n" withString:@"n" options:NSCaseInsensitiveSearch range:NSMakeRange(0,[s length])];

[s replaceOccurrencesOfString:@"b" withString:@"b" options:NSCaseInsensitiveSearch range:NSMakeRange(0,[s length])];

[s replaceOccurrencesOfString:@"f" withString:@"f" options:NSCaseInsensitiveSearch range:NSMakeRange(0,[s length])];

[s replaceOccurrencesOfString:@"r" withString:@"r" options:NSCaseInsensitiveSearch range:NSMakeRange(0,[s length])];

[s replaceOccurrencesOfString:@"t" withString:@"t" options:NSCaseInsensitiveSearch range:NSMakeRange(0,[s length])];

return [NSString stringWithString:s];

}

//我这边的后台有点奇葩 所以要先转字符串在转特殊字符然后在转nsdara 弄了一大圈回到了原点 ，我也知道有点奇葩，但我这里就只能这么转，木有办法

NSData *response = [[HSAssist JSONString:[[NSString alloc] initWithData:[request responseData] encoding:NSUTF8StringEncoding]] dataUsingEncoding:NSUTF8StringEncoding]; NSDictionary *json = [NSJSONSerialization JSONObjectWithData:response options:kNilOptions error:nil]; NSLog(@"%@",json);
