typedef NS_ENUM(NSInteger, UIAlertViewStyle) {
    UIAlertViewStyleDefault = 0, 默认样式
    UIAlertViewStyleSecureTextInput, 密码输入
    UIAlertViewStylePlainTextInput, 文本输入
    UIAlertViewStyleLoginAndPasswordInput 文本和密码输入
};

改变输入框的样式

UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"tishi" message:@"this is" delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:@"queding", nil];

    alert.alertViewStyle = UIAlertViewStyleLoginAndPasswordInput;
    UITextField *textfield = [alert textFieldAtIndex:0];
    textfield.placeholder = @"diyige";
    textfield.secureTextEntry = NO;

    UITextField *text2 = [alert textFieldAtIndex:1];
    text2.placeholder = @"dierge";
    text2.secureTextEntry = NO;
    [alert show];

alertview自动关闭

- (void)viewDidLoad{    [super viewDidLoad];    // Do any additional setup after loading the view.        //alert    UIAlertView *alert=[[UIAlertView alloc]initWithTitle:nil message:@"一个可以自动关闭的Alert窗口" delegate:self cancelButtonTitle:nil otherButtonTitles:nil, nil];    [alert show];        //显示框    UIActivityIndicatorView *indicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];    indicator.backgroundColor=[UIColor redColor];    indicator.center = CGPointMake(alert.bounds.size.width/2,  alert.bounds.size.height-40.0);    [indicator startAnimating];        [alert insertSubview:indicator atIndex:0];        //定时器    [NSTimer scheduledTimerWithTimeInterval:3.0f target:self selector:@selector(dismissAlert:) userInfo:[NSDictionary dictionaryWithObjectsAndKeys:alert, @"alert", @"testing ", @"key" ,nil]  repeats:NO];}//alert 自动消失-(void) dismissAlert:(NSTimer *)timer{        UIAlertView *alert = [[timer userInfo]  objectForKey:@"alert"];    [alert dismissWithClickedButtonIndex:0 animated:YES];    }
