objective c - iPad App Landscape Mode broken iOS 8.3 -

i have app ipad , app landscape right , left orientation..like printscreen:

and i'm using following code rotate view landscape mode:

- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {     [[uiapplication sharedapplication] setstatusbarorientation:uiinterfaceorientationlandscaperight];  cgaffinetransform rotate = cgaffinetransformmakerotation(m_pi/2);     [self.window settransform:rotate];     [self.window setframe:cgrectmake(0, 0, 768, 1024)]; } 

and xib:

it worked fine..but in ios 8.3 doesn't work. appears wrong...see image:

set auto layout constraints viewcontroller objects. , no need write code in didfinishlaunchingwithoptions

[[uiapplication sharedapplication]setstatusbarorientation:uiinterfaceorientationlandscaperight];  cgaffinetransform rotate = cgaffinetransformmakerotation(m_pi/2);  [self.window settransform:rotate];  [self.window setframe:cgrectmake(0, 0, 768, 1024)];
