iOS模拟器风景肖像

Question

I have a iOS application which has been build on XCode earlier iOS 5 and supports the Landscape left , Landscape right and portrait (bottom home ) and from the info.plist --> support interface orientation --> 1 landscape(right home button) 2 landscape(left home button) 3 portrait (bottom home ) to flow of the opening app

Means simulator will open landscape(right home button) by default..

but problem is when I run app in simulator iOS 5.0 --> landscape(right home button) opens by default .

but when i run app in simulator iOS 6.1 --> Portrait mode opens by default.

why iOS 6.1 simulator is opening the Portrait mode when I have set landscape(right home button) to open by default.

is there any issue with the base SDK or anything..as I was building on the earlier versions of the iOS.

Answer 1

The way interface orientations are handled changed in iOS 6. The two main methods to look into are as below :

-(NSUInteger)supportedInterfaceOrientations

and

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation

both declared in UIViewController .

I'd recommend to read View Controller Programming Guide - Supporting Multiple Interface Orientations
