Question

我正在尝试将文本视图放在特定大小的图像视图上，但是当我从照片库中加载图像时，我的文本视图会被覆盖，我无法在其上书写。我想，当我为bi创建一个矩形框架时，来自图库的图像会覆盖到文本视图。我该怎么办？

回答：这是工作的时间：

- (void)imagePickerController:(UIImagePickerController *)picker 
didFinishPickingMediaWithInfo:(NSDictionary *)info {
    // set image
    emailImage1 = [info objectForKey:UIImagePickerControllerOriginalImage];
    //bi.image = [info objectForKey:UIImagePickerControllerOriginalImage];

    image = [info objectForKey:UIImagePickerControllerOriginalImage];
    bi = [[UIImageView alloc ] initWithImage: image ];
    bi.frame = CGRectMake(20.0f, 100.0f,260.0f, 285.0f);
    [self.view addSubview: bi];
    [self.view bringSubviewToFront:scroll];
    [[picker parentViewController] dismissModalViewControllerAnimated:YES];
    [picker release];
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker 
   {
    // release picker
    [[picker parentViewController] dismissModalViewControllerAnimated:YES];
    [picker release];
}

Answer 1

嘿那里，有一条线引起了问题。您可以将bi添加为子视图，如下所示：

[self.view addSubview: bi ];

这是对的。但是从UIView的实践看这个：

添加后，此视图会显示在任何其他子视图的顶部。

请尝试以下

[self.view insertSubview: bi belowSubview: YourTextView];

将'YourTextView'替换为指向textview的指针。它应该工作。
