 NSMutableArray *tempArr = [NSMutableArray array];
 //这里不要用for-in 先找到模型，然后给可变字典赋值，最后装到数组里
    NSMutableDictionary *dic = [NSMutableDictionary dictionary];
    for (int i = 0; i < self.dataSourceArr.count; i++) {
        PerponModel *model = self.dataSourceArr[i];
        [dic setValue:model.name forKey:@"realname"];
        [dic setValue:model.phoneNumber forKey:@"mobile"];
        [tempArr addObject:dic];
    }
    //dataWithJSONObject：后面这个是一个id类型的这样放数组就转数组，字典就转字典
    //NSJSONWritingPrettyPrinted是一个枚举
    NSData *data = [NSJSONSerialization dataWithJSONObject:tempArr options:NSJSONWritingPrettyPrinted error:nil];
    NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
