Question

我创建了runtime image view并向其添加了subviews（仅like splash screen概念）。现在我要为我的iPad处理所有4个旋转但它的方法是什么？

我的代码段：

    UIView *mainScreen = [[[UIApplication sharedApplication]delegate]window];        
    UIView *windowBlocker = [[UIView alloc]initWithFrame:mainScreen.frame];
    windowBlocker.tag = 999;
    imageView = [[UIImageView alloc] initWithFrame:CGRectMake(165, 200, 450, 480)];        
    imageView.layer.backgroundColor=[[UIColor colorWithRed:248/255 green:248/255 blue:248/255 alpha:0.5] CGColor];
    imageView.alpha = 0.6;

    imageView.layer.cornerRadius=10;
    imageView.layer.masksToBounds = YES;
    [windowBlocker addSubview:imageView];

以下方法为每次轮换设置每个子视图的坐标会很痛苦。不是吗？如何在这里处理轮换。我还必须禁用自动布局以进行滚动。

-(void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
    if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
        NSLog(@"Landscape left");
        self.lblInfo.text = @"Landscape left";
    } else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) {
        NSLog(@"Landscape right");
        self.lblInfo.text = @"Landscape right";
    } else if (toInterfaceOrientation == UIInterfaceOrientationPortrait) {
        NSLog(@"Portrait");
        self.lblInfo.text = @"Portrait";
    } else if (toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
        NSLog(@"Upside down");
        self.lblInfo.text = @"Upside down";
    }
}

请指导。感谢

UIView *mainScreen = [[[UIApplication sharedApplication]delegate]window];
UIView *windowBlocker = [[UIView alloc]initWithFrame:mainScreen.frame];
windowBlocker.tag = 999;
imageView = [[UIImageView alloc] initWithFrame:CGRectMake(165, 200, 450, 480)];
imageView.layer.backgroundColor=[[UIColor colorWithRed:248/255 green:248/255 blue:248/255 alpha:0.5] CGColor];
imageView.alpha = 0.6;

imageView.layer.cornerRadius=10;
imageView.layer.masksToBounds = YES;
[windowBlocker addSubview:imageView];

    [[[mainScreen subviews] objectAtIndex:0] addSubview:windowBlocker];
