ios - 如何让应用保持纵向模式

Question

当我运行它时，我似乎无法将我的应用程序保持在纵向模式，我将支持的设备方向设置为仅纵向并且它仍然旋转，所有帮助将不胜感激，谢谢！

Answer 1

在所有视图控制器中写这个

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return NO;
}

同样在 project-info.plist

更改键的值

<key>UISupportedInterfaceOrientationss</key>
<array>
    <string>UIInterfaceOrientationPortrait</string>
    <string>UIInterfaceOrientationLandscapeLeft</string>
    <string>UIInterfaceOrientationLandscapeRight</string>
</array>

至

<key>UISupportedInterfaceOrientationss</key>
<array>
    <string>UIInterfaceOrientationPortrait</string>
</array>

Answer 2

将此写入所有视图控制器：

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