1. JSON字符串转化为字典 + (NSDictionary *)dictionaryWithJsonString:(NSString *)jsonString { if (jsonString == nil) { return nil; } NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding]; NSError *err; NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&err]; if(err) { NSLog(@"json解析失败:%@",err); return nil; } return dic; }
2. 字典转Json字符串 // 字典转json字符串方法 -(NSString *)convertToJsonData:(NSDictionary *)dict { NSError *error; NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict options:NSJSONWritingPrettyPrinted error:&error]; NSString *jsonString; if (!jsonData) { NSLog(@"%@",error); }else{ jsonString = [[NSString alloc]initWithData:jsonData encoding:NSUTF8StringEncoding]; } NSMutableString *mutStr = [NSMutableString stringWithString:jsonString]; NSRange range = {0,jsonString.length}; //去掉字符串中的空格 [mutStr replaceOccurrencesOfString:@" " withString:@"" options:NSLiteralSearch range:range]; NSRange range2 = {0,mutStr.length}; //去掉字符串中的换行符 [mutStr replaceOccurrencesOfString:@"\n" withString:@"" options:NSLiteralSearch range:range2]; return mutStr; }
