是否可以在 UIAlertView 中显示图像？

Question

是否可以在 UIAlertView 中添加图像，例如显示 plist 文件中的图像？

Answer 1

你可以这样做：

UIAlertView *successAlert = [[UIAlertView alloc] initWithTitle:title message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];

    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(220, 10, 40, 40)];

    NSString *path = [[NSString alloc] initWithString:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"smile.png"]];
    UIImage *bkgImg = [[UIImage alloc] initWithContentsOfFile:path];
    [imageView setImage:bkgImg];

    [successAlert addSubview:imageView];

    [successAlert show];

这将在您的警报视图的右上角添加一个图像，您可以更改框架图像以四处移动。

希望这会有所帮助。

在 iOS 7 或更高版本中，使用此代码

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200, 282)];
UIImage *wonImage = [UIImage imageNamed:@"iberrys.png"];
imageView.contentMode=UIViewContentModeCenter;
[imageView setImage:wonImage];
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Arirang List"
                                                     message:@"phiên bản: 1.0\n website: www.iberrys.com\n email: quangminh@berrys.com\nmobile: 0918 956 456"
                                                    delegate:self
                                           cancelButtonTitle:@"Đồng ý"
                                           otherButtonTitles: nil];
//check if os version is 7 or above
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
    [alertView setValue:imageView forKey:@"accessoryView"];
}else{
    [alertView addSubview:imageView];
}
 [alertView show];

Answer 3

您需要继承 UIAlertView 并重新排列其子视图。这种东西有几个教程：

• Custom UIAlertView（可能最适合您的问题）
• Custom UIAlertView w/ TableView（也很方便）

Answer 4

UIAlertView *Alert = [[UIAlertView alloc] initWithTitle:@"your Title" message:@"Your   Message" delegate:nil cancelButtonTitle:@"Your Title" otherButtonTitles:nil];

UIImageView *image = [[UIImageView alloc] initWithFrame:CGRectMake(0,0, 40, 40)];

NSString *loc = [[NSString alloc] initWithString:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"Your Image Name"]];
UIImage *img = [[UIImage alloc] initWithContentsOfFile:loc];
[image setImage:img];

if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
    [Alert setValue:image forKey:@"accessoryView"];
}else{
    [Alert addSubview:image];
}

[Alert show];

Answer 5

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200, 282)];
UIImage *wonImage = [UIImage imageNamed:@"iberrys.png"];
imageView.contentMode = UIViewContentModeCenter;
[imageView setImage:wonImage];
UIAlertView *alertView = [[UIAlertView alloc]  initWithTitle:@"Arirang List"
                                                     message:@"phiên bản: 1.0\n website: www.iberrys.com\n email: quangminh@berrys.com\nmobile: 0918 956 456"
                                                    delegate:self
                                           cancelButtonTitle:@"Đồng ý"
                                           otherButtonTitles:nil];
//check if os version is 7 or above
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
    [alertView setValue:imageView forKey:@"accessoryView"];
} else {
    [alertView addSubview:imageView];
}
[alertView show];

我对 Madhup 提供的解决方案做了一些修改。

Madhup 的解决方案适用于短消息，但是， 消息过长时，会被图片覆盖。

因此，我在 UIAlertViewDelegate 的方法中添加了以下步骤 - (void)willPresentAlertView:(UIAlertView *)alertView

1. 添加8个“\n”作为消息前缀，将消息下推， 为图像保留空间（我的图像被限制在 100x150）

2. 检测AlertView的子视图，判断UITextView是否存在。

   UITextView只有在消息过长时才会存在。

3. 如果 UITextView 不存在，一切都会好的，图片 显示良好，消息显示良好。

4. 如果UITextView存在，去掉UITextView.text中的8个前缀“\n”， 然后调用 UITextView.setFrame 来调整 UITextview 的大小和位置。

上述操作效果很好。

我发送一个 NSDictionary 作为要显示的消息，字典包含 2 个键值对，“msg”=>真正的消息字符串。 "url"=>来自网站的图片。

使用 NSURLConnection sendSynchronousRequest 方法，代码将在途中从互联网检索图像数据。

- (void)showAlertView:(NSDictionary *)msgDic {
    NSLog(@"msgDic = %@", msgDic);
    NSMutableString *msg = [[NSMutableString alloc] initWithString:@"\n\n\n\n\n\n\n\n"];
    if ([msgDic objectForKey:@"msg"]) {
        [msg appendFormat:@"%@", [msgDic objectForKey:@"msg"]];
    }
    else {
        [msg setString:[msgDic objectForKey:@"msg"]];
    }

    NSLog(@"msg = %@", msg);
    UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Alert Title"
                                                message:msg
                                               delegate:self
                                    cancelButtonTitle:@"Close" otherButtonTitles:nil];

     if ([msgDic objectForKey:@"url"]) {
         NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:[msgDic objectForKey:@"url"]]];
         [request setCachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData];

         NSData *imgData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
         if (imgData) {
             UIImage *shownImage = [UIImage imageWithData:imgData];
             UIImageView *imgView = [[UIImageView alloc] initWithImage:shownImage];
             [imgView setFrame:CGRectMake(floor(284-100)/2.0, 47, 100, 150)];

             [alert addSubview:imgView];
             [imgView release];
         }
     }

    alert.delegate = self;
    [alert show];
    [alert release];
    [msgDic release];
}

- (void)willPresentAlertView:(UIAlertView *)alertView {
int viewCount = [alertView.subviews count];

    NSLog(@"subviews count = %i", viewCount);

    if (viewCount > 0) {
        BOOL bFoundTextView = NO;
        for (int count=0; count<=[alertView.subviews count] -1; count++) {
            BOOL bIsTextView = NO;
            UIView *subView = [alertView.subviews objectAtIndex:count];
            NSLog(@"view index %i classname = %@", count, [[subView class] description]);

            bIsTextView = [[[subView class] description] isEqualToString:@"UIAlertTextView"];
            bFoundTextView |= bIsTextView;

            if (bIsTextView) {
                UITextView *textView = (UITextView *)subView;
                NSMutableString *msg = [[NSMutableString alloc] initWithString:textView.text];
                [msg setString:[msg substringFromIndex:8]];
                textView.text = msg;

                CGRect frame = textView.frame;
                if (frame.origin.y != 205) {
                    frame.origin.y = 205;
                    frame.size.height -= 155;
                    [textView setFrame:frame];
                }

                [msg release];
            }
        }        
    }
}

IOS 7 及更高版本的注意事项

if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
    [alert setValue:imageView forKey:@"accessoryView"];
}else{
    [alert addSubview:imageView];
}

Answer 8

Swift 版本：

    let alertView = UIAlertView(title: "Alert", message: "Alert + Image", delegate: nil, cancelButtonTitle: "OK")
    let imvImage = UIImageView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
    imvImage.contentMode = UIViewContentMode.Center
    imvImage.image = UIImage(named: "image_name")
    alertView.setValue(imvImage, forKey: "accessoryView")
    alertView.show()

Answer 9

使用纯布局 pod：

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Hello"
                                                                         message:nil
                                                                  preferredStyle:UIAlertControllerStyleAlert];
UIImage *image = // target image here;
CGSize size = image.size;
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(leftMargin, topMargin, size.width, size.height)];
imageView.image = image;
[alertController.view addSubview:imageView];
[imageView autoPinEdgeToSuperviewEdge:ALEdgeLeft withInset:leftMargin];
[imageView autoPinEdgeToSuperviewEdge:ALEdgeTop withInset:topMargin];
[imageView autoPinEdgeToSuperviewEdge:ALEdgeRight withInset:rightMargin];
[imageView autoPinEdgeToSuperviewEdge:ALEdgeBottom withInset:bottomMargin];
[imageView autoSetDimension:ALDimensionWidth toSize:size.width];
[imageView autoSetDimension:ALDimensionHeight toSize:size.height];
// add desired actions here
[self presentViewController:alertController animated:YES completion:nil];
