兩種json字串拼接的方法如下:

+ (NSString *)UIUtilsFomateJsonWithDictionary:(NSDictionary *)dic {

    NSArray *keys = [dic allKeys];

    NSString *string = [NSString string];

    

    for (NSString *key in keys) {

        NSString *value = [dic objectForKey:key];

 

        value = [NSString stringWithFormat:@"\"%@\"",value];

        NSString *newkey = [NSString stringWithFormat:@"\"%@\"",key];

        

        

        if (!string.length) {

            string = [NSString stringWithFormat:@"%@:%@}",newkey,value];

        }else {

            string = [NSString stringWithFormat:@"%@:%@,%@",newkey,value,string];

        }

    }

    string = [NSString stringWithFormat:@"{%@",string];

    return string;

}

 

+ (NSString *)UIUtilsFomateJsonArrWithArray:(NSArray *)array {

    

    NSString *string = [NSString string];

    for (int j = 0; j<array.count; j++) {

        NSDictionary *dic = array[j];

        NSArray *keys = [dic allKeys];

        

        for (int i = 0; i<keys.count; i++) {

            NSString *key = keys[i];

            NSString *value = [dic objectForKey:key];

            value = [NSString stringWithFormat:@"\"%@\"",value];

            key = [NSString stringWithFormat:@"\"%@\"",key];

            

            

            if (!string.length) {

                string = [NSString stringWithFormat:@"%@:%@}",key,value];

                

            }else if(i == 0){

                string = [NSString stringWithFormat:@"%@:%@}%@",key,value,string];

                

            }else {

                string = [NSString stringWithFormat:@"%@:%@,%@",key,value,string];

            }

        }

        

        if (j != array.count-1) {

            string = [NSString stringWithFormat:@",{%@",string];

        }else {

            string = [NSString stringWithFormat:@"[{%@]",string];

        }

    }

    return string;

}

 

調用:

第一種直接傳入@"key":@"value"}即可,

第二種array裡面對象需要是字典:NSArray *array = @[@{@"key":@"value"}];
