iPhone视图显示错误的方向-Java 学习之路

我正在努力解决这个问题 . 我的App需要纵向视图和横向视图 . 现在，当我创建2个按钮，向我显示纵向视图和横向视图（由shouldAutorotateToInterfaceOrientation强制）时，它们显示正常 . 但是当我从一个图像选择器的结果代码中调用视图时，portraitview工作得很好，但是这样返回了横向视图 . http://bit.ly/bfbobc .

所以只是说清楚：nob已经转了90度，imageviewcontrol只显示了一半（右边的部分是屏幕外的）......但iPhone并没有被强制进入横向模式......

有人可以解释一下这里发生了什么，或者我如何实现这一目标！欢迎任何帮助！

这就是我使用imagepickercontroller结果代码调用视图的方法 .

` - （void）imagePickerController：（UIImagePickerController *）vcImagePicker didFinishPickingMediaWithInfo：（NSDictionary *）info {NSLog（@“图片被拍摄/选择，现在我们需要决定呈现哪个视图”）;

[vcImagePicker dismissModalViewControllerAnimated:YES];

UIImage *chosenPicture = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

if (chosenPicture.size.width > chosenPicture.size.height) {
    NSLog(@"pic is in landscape");

    EditLandscapeScreen *vcEditLandscapeScreen = [[EditLandscapeScreen alloc] initWithNibName:@"EditLandscapeScreen" bundle:nil];
    vcEditLandscapeScreen.ChosenImage = chosenPicture;
    [self.view addSubview:vcEditLandscapeScreen.view]; 
    [vcEditLandscapeScreen release];
}
else {
    NSLog(@"pic is in portrait");

    EditPortraitScreen *vcEditPortraitScreen = [[EditPortraitScreen alloc] initWithNibName:@"EditPortraitScreen" bundle:nil];
    vcEditPortraitScreen.ChosenImage = chosenPicture;
    [self.view addSubview:vcEditPortraitScreen.view]; 
    [vcEditPortraitScreen release];
}

如果将子视图添加到视图，则必须自行更改子视图的方向 . willRotateToInterfaceOrientation 只会调用第一个viewcontroller，因此如果您将Subviews添加到viewcontroller，这可能是您可接受的方式：

在您的ViewController中：

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
    for (int i = 0; i < [self.viewControllers count]; i++ ) {
        [[self.viewControllers objectAtIndex:i] didRotateFromInterfaceOrientation:fromInterfaceOrientation];
    }
}

在你Subview ViewController：

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{
    [self adjustViewsForOrientation:self.interfaceOrientation];
}

    - (void) adjustViewsForOrientation:(UIInterfaceOrientation)orientation {
        if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight) {
            NSLog(@"Subview Landscape");
            //Do Your Landscape Changes here
        }
        else if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown) {
            NSLog(@"Subview Portrait");
            //Do Your Portrait Changes here
        }
    }

这可能会让你朝着正确的方向前进 .
