Forcing the portrait orientation for my View

Question

I am working on ARC based project. My project is targeted iOS 4.3 I want to force the

Portrait orientation to one of my view. The following doesn't seem to work for me.

[[UIDevice currentDevice] performSelector:NSSelectorFromString(@"setOrientation:") withObject:(id)UIInterfaceOrientationPortrait];

Any help on this?

Answer 1

First of all the viewController to which orientations need to supported must implement the below method passing the supported orientations.

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation

Later to manually rotate the view set the device orientation directly using

[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait];

if this doesn't work use

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:YES];

remember if you return NO for the setting orientation in shouldAutoRotate this may not work. Also check this in both ios5 & ios6, i have tried in ios5.

EDIT: For iOS5 or iOS6 where setOrientation doesn't exist

[[UIDevice currentDevice] performSelector:NSSelectorFromString(@"setOrientation:") withObject:(id)UIInterfaceOrientationPortrait];

this works fine, but this may be a private api now.
