Question

我想要显示登录窗口，然后键入登录和密码密码，它将打开帐户。所以我尝试了，但是它显示了错误，比如/81: error：'didReceiveMemoryWarning‘未声明(在这个函数中第一次使用) *:81: error：100之前的'{’令牌* 100:错误:在输入末尾的预期声明或语句

我在下面贴了代码，请帮忙，谢谢。

#import <UIKit/UIKit.h>

@interface Password1ViewController : UIViewController {

UITextField *textfieldName;
UITextField *textfieldPassword;

@property (nonatomic, retain) IBOutlet UITextField *textfieldName;
@property (nonatomic, retain) IBOutlet UITextField *textfieldPassword;
