xcode UIALert查看带文本的多个按钮

UIALertView multiple buttons with text

提问by user1970792

I have an alertview with 3 buttons and text(label and NOT textView) If I jam it all together, it'll become ugly with this tiny scroll-text and all the buttons taking up most of the space. Does anyone know how to fix this?

我有一个带有 3 个按钮和文本（标签而不是文本视图）的警报视图，如果我将它们全部塞在一起，这个微小的滚动文本和所有按钮占据大部分空间会变得丑陋。有谁知道如何解决这一问题？

Why don't you try to create a custom View for this.

为什么不尝试为此创建自定义视图。

You can use as you want to customize, size, color, background etc.

您可以根据需要自定义大小、颜色、背景等。

And show it as a modal window/view.

并将其显示为模态窗口/视图。

If you still want to use alertView then you can give spacing as:

如果您仍然想使用 alertView 那么您可以将间距设置为：

UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Title" message:@"\n\n!\n\n\n\n" delegate:self cancelButtonTitle:@"Button 1" otherButtonTitles:@"Button 2",@"Button 3", nil];
[alert show];

A simple way to move the text view down is to add a message

向下移动文本视图的一种简单方法是添加一条消息

[alertViewObject setMessage:@"\n"];

THe reason for your frame isn't taking effect is that -show sets the frame and creates the view hierarchy before starting the animation. You should also make the text view the first responder so the keyboard pops up.

您的框架未生效的原因是 -show 在开始动画之前设置框架并创建视图层次结构。您还应该使文本视图成为第一响应者，以便弹出键盘。

Customize your AlertView by using following Code.

使用以下代码自定义您的 AlertView。

// Customize Alert View
UIAlertView *alertView = [UIAlertView new];
alertView.title = @"Alert Title";


// Adding Your Buttons
[alertView addButtonWithTitle:@"Button1"];
[alertView addButtonWithTitle:@"Button2"];
[alertView addButtonWithTitle:@"Button3"];
[alertView addButtonWithTitle:@"Button4"];


// Add a Space for Text View
alertView.message = @"\n";


// View heirarchy, set its frame and begin bounce animation
[alertView show];


// Set the frame
CGRect frame = alertView.frame;
frame.origin.y -= 100.0f;
alertView.frame = frame;


// Adding TextField
UITextField* text = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)];
text.borderStyle = UITextBorderStyleRoundedRect;
[alertView addSubview:text];
[text becomeFirstResponder]; 

I hope this will help you.

我希望这能帮到您。

UIAlertView was deprecated in iOS 9.0. Use UIAlertController with a preferredStyle of UIAlertControllerStyleAlert instead.

UIAlertView 在 iOS 9.0 中被弃用。使用 UIAlertController 和首选样式 UIAlertControllerStyleAlert 代替。

    let alertController = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)

    alertController.addAction(UIAlertAction(title: "AlertAction 0", style: .default, handler: { (alertAction: UIAlertAction) in
        print("0")
    }))

    alertController.addAction(UIAlertAction(title: "AlertAction 1", style: .default, handler: { (alertAction: UIAlertAction) in
        print("1")
    }))

    alertController.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (alertAction: UIAlertAction) in
        print("cancel")
    }))

I suggest that you make two uiaertviews and then use

我建议你制作两个uiaertviews然后使用

    - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

to check which alert view was clicked. If you really need an uialertview, else the answer below is also great.

检查点击了哪个警报视图。如果您真的需要 uialertview，否则下面的答案也很棒。

Detailed:

详细的：

1. Add a uialertview delegate to your view controller:

   @interface ViewController : UIViewController <UIAlertViewDelegate>    
   

2. When creating the 2 alertViews it should look like this:

   UIAlertView *alert1 = [[UIAlertView alloc] initWithTitle:@"Message" message:@"the first UIAlertView" delegate: self cancelButtonTitle:@"Back" otherButtonTitle:@"More Options", nil];
   

1. 将 uialertview 委托添加到您的视图控制器：

   @interface ViewController : UIViewController <UIAlertViewDelegate>    
   

2. 创建 2 个 alertViews 时，它应该如下所示：

   UIAlertView *alert1 = [[UIAlertView alloc] initWithTitle:@"Message" message:@"the first UIAlertView" delegate: self cancelButtonTitle:@"Back" otherButtonTitle:@"More Options", nil];
   

and the second:

第二个：

    UIAlertView *alert2 = [[UIAlertView alloc] initWithTitle:@"More Options" message:nil delegate:self cancelButtonTitle:@"Back" otherButtonTitle:@"Option 1", @"Option 2", @"Option 3", nil];

1. In your ViewController.m add:

   - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
   
   if (alertView == alert1) {
     [alert2 show];
   }
   
   else if (alertView == alert2) {        
   
   NSString *string = [alertView buttonTitleAtIndex:buttonIndex];
   
   if ([string isEqualToString:@"Option 1"]) {
   
       //Do stuff
   
   }
   else if ([string isEqualToString:@"Option 2"]) {
   
       //Do something else
   }
   else if ([string isEqualToString:@"Option 3"]) {
   
       //Do something 3rd
   }
   }
   

1. 在您的 ViewController.m 添加：

   - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
   
   if (alertView == alert1) {
     [alert2 show];
   }
   
   else if (alertView == alert2) {        
   
   NSString *string = [alertView buttonTitleAtIndex:buttonIndex];
   
   if ([string isEqualToString:@"Option 1"]) {
   
       //Do stuff
   
   }
   else if ([string isEqualToString:@"Option 2"]) {
   
       //Do something else
   }
   else if ([string isEqualToString:@"Option 3"]) {
   
       //Do something 3rd
   }
   }
