创建字典注意事项1

NSDictionary *paramAddr = [[NSDictionary alloc] initWithObjectsAndKeys:

_registerUser.au_name,@"au_name",     _registerUser.au_password,@"au_password",_house_area.text,@"hou_area",

_hou_id,@"hou_id",

_au_is_binding,@"au_is_binding",

nil];

上面方法创建字典时，多个Key的时候，中间有回车换行的话，会导致字典缺少元素。

建议按如下方法（添加前最好判断各个值是否为空的情况）：

NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];

[dic setObject:_registerUser.au_name forKey:@"au_name"];

[dic setObject:_registerUser.au_password forKey:@"au_password"];

[dic setObject:_house_area.text forKey:@"hou_area"];

[dic setObject:_hou_id forKey:@"hou_id"];

[dic setObject:_au_is_binding forKey:@"au_is_binding"];
