Ios4 iphone gmail代码示例

我想显示登录窗口，然后键入login和password Credential，它将打开帐户。所以我试过了，但它显示出类似的错误 /81:错误：“didReceiveMemoryWarning”未声明（此函数首次使用） *：81:错误：应为“；”在“{”标记之前* 100:错误：输入结束时需要声明或语句

我在下面贴了代码，请帮忙 提前谢谢

.h文件

#import <UIKit/UIKit.h>

@interface Password1ViewController : UIViewController {

UITextField *textfieldName;
UITextField *textfieldPassword;

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

@end

您缺少我在编辑中更正的右大括号。因此，现在请尝试编辑代码。

在每个代码行之前使用四个空格，如果在循环中编写代码，则再使用四个空格，依此类推。在循环中编写代码时，您可以随时预览代码。
