IOS7 Navigation bar Adaptation

Problem:

In Appdelegate

-(BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: (Nsdictionary *) launchOptions {

Viewcontroller *vc=[[viewcontroller Alloc]init];

Uinavigationcontroller *nav=[[uinavigationcontroller ALLOC]INITWITHROOTVIEWCONTROLLER:VC];

Nav.view.backgroundColor = [Uicolor Bluecolor];

Self.window.rootviewcontroller=nav;

return YES;

}

In the Viewcontroller:

-(void) viewdidload {[Super viewdidload];//if ([Self respondstoselector: @selector (setedgesforextendedlayout:)])// {//Self.edgesforextendedlayout = uirectedgenone;//}//Self.navigationController.navigationBar.translucen    T=no;    Self.view.backgroundcolor=[uicolor Clearcolor]; Uiscrollview *segmentscorllview = [[Uiscrollview alloc] Initwithframe:cgrectmake (0, 164, Self.view.frame.size.width,    44)];    Segmentscorllview.backgroundcolor=[uicolor Greencolor];    UIButton *button = [UIButton buttonwithtype:uibuttontypecustom];    [Button setframe:cgrectmake (0, 0, 50, 44)];    [Button settitle:@ "AAA" forstate:uicontrolstatenormal];    [Button Settitlecolor:[uicolor Bluecolor] forstate:uicontrolstateselected];    [Button Settitlecolor:[uicolor Redcolor] forstate:uicontrolstatenormal];    Button.backgroundcolor = [Uicolor Browncolor];    [Button.titlelabel Setfont:[uifont systemfontofsize:15];    [Segmentscorllview Addsubview:button]; [Self.view addsubview:segmentScorllview];}
