从枚举类型“enum UIDeviceOrientation”隐式转换为不同的枚举类型“UIInterfaceOrientation“”枚举UIInterfaceOrientation

我正在使用Xcode 5.0.2,在尝试编译目标C代码时收到以下警告:

从枚举类型“enum UIDeviceOrientation”隐式转换 到不同的枚举类型“UIInterfaceOrientation”(又名“enum” UI界面方向')

警告显示在viewController.m中

-(void)youTubeStarted:(NSNotification *)notification{
    // your code here
    NSLog(@"youTubeStarted");
    **[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationPortrait animated:NO];**
}

-(void)youTubeFinished:(NSNotification *)notification{
    // your code here
    NSLog(@"youTubeFinished");
}

- (void)youTubeVideoExit:(id)sender {
    **[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationPortrait animated:NO];**
}
