Creating "IOS Project" in xcode 5 causes the following when launching for iPad simulator. The application works for iPhones configuration. I have set the target to be 5 and later and removed autolayout as its not compatible with ios/xcode 5.

I get the following error at launch of iPad app.

2013-08-29 08:53:57.688 IOS Project[350:c07] -[MasterViewController    setPreferredContentSize:]: unrecognized selector sent to instance 0x9e2cc20

In iOS7, UIViewController has a new property preferredContentSize. A project made for iOS7 has the following method:

- (void)awakeFromNib
{
    self.preferredContentSize = CGSizeMake(320.0, 480.0);
    [super awakeFromNib];
}

It therefore sends a setPreferredContentSize: message to your own controller, no matter if the property is implemented or not. To resolve the issue, you might want to avoid setting a property that does not exist:

- (void)awakeFromNib
{
    if ([[[UIDevice currentDevice] systemVersion] compare:@"7" options:NSNumericSearch] != NSOrderedAscending) {
        self.preferredContentSize = CGSizeMake(320.0, 480.0);
    }
    [super awakeFromNib];
}
