禁用纵向模式

Question

我正在开发一个iPhone应用程序，该应用程序应该只在横向模式下工作。但是，当我旋转设备或模拟器时，viewContoller的模式从横向更改为纵向。我希望viewController在横向模式下维护，尽管设备或模拟器是纵向的。我怎么能做到这一点？提前谢谢。

Answer 1

在视图控制器中覆盖此方法：

// Override to allow orientations other than the default portrait orientation.
-(BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientation, NO for other;
}

Answer 2

将此添加到您的ViewController.m

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
        return UIInterfaceOrientationIsLandscape(interfaceOrientation);   
}

Answer 3

更改info_plist .. 支持的界面方向仅设置横向

Answer 4

在所有ViewControllers中重写此方法：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight ||
            interfaceOrientation == UIInterfaceOrientationLandscapeLeft);

}
