How do you disable screen rotation using Cocoa-Touch? - ios

Question

I can't disable screen rotation with:
- (BOOL)shouldAutorotate {
return NO;
}
screen rotation will disable only if I disabled it from the general info of the project
but I don't wont to disable it from there, this is my code (not a lot):
#import "MainPage.h"
#import "Reachability.h"
#interface MainPage ()
#end
#implementation MainPage
Reachability *internetReachableFoo;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidLoad];
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
{
CGSize result = [[UIScreen mainScreen] bounds].size;
if(result.height == 480)
{
background.frame = CGRectMake(0, 0, 320, 480);
about.frame = CGRectMake(20, 401, 280, 44);
}
}
NSUserDefaults *userdetails =[NSUserDefaults standardUserDefaults];
NSString *userid = [userdetails objectForKey:#"userid"];
NSString *username = [userdetails objectForKey:#"username"];
if (userid != NULL && username != NULL) {
[self performSegueWithIdentifier:#"Home" sender:self];
NSLog(#"connceted");
}
else
{
signOutlet.hidden = NO;
loginOutlet.hidden = NO;
}
}
- (BOOL)shouldAutorotate {
return NO;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
I am using IOS 8 and IOS 7 any idea ?
* edit *
ok, I don't get it in other VC its work and can't rotate
this is my other VC (I don't see any change)
#import "About.h"
#interface About ()
#end
#implementation About
- (void)viewDidLoad {
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
{
CGSize result = [[UIScreen mainScreen] bounds].size;
if(result.height == 480)
{
background.frame = CGRectMake(0, 0, 320, 480);
aboutText.frame = CGRectMake(15, 68, 290, 319);
home.frame = CGRectMake(67, 414, 187, 38);
}
}
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (BOOL)shouldAutorotate {
return NO;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end

You need to include the supportedInterfaceOrientations method in your view controller along with the shouldAutorotate method. So lets say you want this one specific view controller limited to only the Portrait orientation, you would have:
#import "MyViewController.h"
#interface MyViewController ()
#end
#implementation MyViewController
- (void)viewDidLoad {
[super viewDidLoad];
//...
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
//...
}
- (NSUInteger)supportedInterfaceOrientations {
// support only portrait landscape
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL) shouldAutorotate {
// have autorotate set to YES so the screen can rotate if not in Portrait orientation
return YES;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
// not necessary, but this makes the view start in Portrait orientation on the initial load
return UIInterfaceOrientationPortrait;
}
#end
Hope this helps
