設定裝置的能否橫屏或者豎屏的設定在target->general->deployment info->device orientation中設定,如圖:
首先,獲取螢幕的寬高:
#define width self.view.frame.size.width
#define height self.view.frame.size.height
_myview=[[uiview alloc]init];
_myview.frame=cgrectmake(0, 0, width, height);
_myview.backgroundcolor=[uicolor greencolor];
[self.view addsubview:_myview];
uilabel *lbl=[[uilabel alloc]init];
lbl.text=@"測試橫屏豎屏";
lbl.frame=cgrectmake(width/2-80, 100, 140, 40);
[_myview addsubview:lbl];
- (void)willanimaterotationtointe***ceorientation:(uiinte***ceorientation)inte***ceorientation duration:(nstimeinterval)duration
}
if (currentorientation == uiinte***ceorientationportrait ||currentorientation == uiinte***ceorientationportraitupsidedown) else
ok,問題解決!
用**設定當前是否允許橫屏或豎屏
-(nsuinteger)supportedinte***ceorientations
