檢測手機朝向UIDevice，檢測朝向uidevice

- (void)viewDidLoad{    [super viewDidLoad];    //檢測裝置朝向使用UIDevice,beginGeneratingDeviceOrientationNotifications方法向通知中樞發送朝向資訊    [[UIDevice currentDevice]beginGeneratingDeviceOrientationNotifications];    //建立通知中樞    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(orientationChanged:) name:UIDeviceOrientationDidChangeNotification object:nil];}

-(void)orientationChanged:(NSNotification *)notification{    UIDeviceOrientation orientation=[[UIDevice currentDevice]orientation];    switch (orientation) {        case UIDeviceOrientationFaceUp:            NSLog(@"裝置正面朝上");            break;            case UIDeviceOrientationFaceDown:            NSLog(@"裝置正面朝下");            break;            case UIDeviceOrientationPortrait:            NSLog(@"裝置處於正常朝向,主畫面按鈕在下方");            break;            case UIDeviceOrientationPortraitUpsideDown:            NSLog(@"裝置處於縱向,主畫面按鈕在上方");            break;            case UIDeviceOrientationLandscapeLeft:            NSLog(@"裝置側立,左邊朝下");            break;            case UIDeviceOrientationLandscapeRight:            NSLog(@"裝置側立,右邊朝下");            break;        default:            break;    }}

附:檢測手機版本資訊使用的也是UIDevice.

    //擷取硬體資訊    UIDevice *device=[UIDevice currentDevice];    //輸出版本號碼    NSLog(@"%@",device.systemVersion);
