I am making an iPhone app and I need it to be in portrait mode, so if the user moves the device sideways, it does not automatically rotate. How can I do this?
If you want to disable landscape orientation for both iPhone and iPad.
Go to Targets and Go to the General tab. See the below screen and deselect landscape left and landscape right.
Here in this case only iPhone landscape mode will be disabled not for iPad. For iPad all modes are anabled. If you want select device option from Universal to iPad. It will looks like this. See below screen.
Now you need to deselect all modes except Portrait for iPad. See below screenshot.
Now you successfully disabled all modes except Portrait for all devices.
