本文档提供了一个简单的iOS应用示例，展示了如何在Objective-C中创建和展示UIAlertView，并通过UIAlertViewDelegate处理用户交互。示例代码包括视图控制器的初始化、内存警告处理以及UIAlertView的配置与显示。

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
-(IBAction)alert{
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"提示框" message:@"测试提示框" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"好", nil];

    //有三种风格
    [alertView setAlertViewStyle:UIAlertViewStylePlainTextInput];
    [alertView show];
}
#pragma mark -
#pragma UIAlertViewDelegate
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger) buttonIndex{
    UITextField *text = [alertView textFieldAtIndex:0];
   NSLog(@"输出=%@",text.text);
}
#pragma mark
@end
