iPad相机定位问题

Question

我正在实施一个关于摄像机模式功能的应用程序，但应用程序仅运行横向但摄像机在IPad的某些部分打开，仅剩余为黑色。

    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
        camPicker.sourceType =  UIImagePickerControllerSourceTypeCamera;
        camPicker.delegate = self;
        camPicker.allowsEditing = NO;
        [self presentModalViewController:camPicker animated:YES];

对于定位为

的方向

if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
    return interfaceOrientation == UIInterfaceOrientationLandscapeLeft;

}else
{
    return interfaceOrientation == UIInterfaceOrientationLandscapeRight;

}

Answer 1

将方向设置为：

 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight || interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
