发布应用程序Iphone肖像和Ipad景观

我有这个代码，我需要检测的是ipad发布应用程序场景还是iphone仅处于纵向模式

    NSString *deviceType = [UIDevice currentDevice].model;

    if([deviceType isEqualToString:@"iPhone"])
    {
        NSLog(@"This is iPhone");
    }
    else
    {
        NSLog(@"This is iPad");
    }

这很有效！！！对于IOS 6

-(NSUInteger)supportedInterfaceOrientations{

    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)

        return UIInterfaceOrientationMaskPortrait;
    else
        return UIInterfaceOrientationMaskLandscape;
}

- (BOOL)shouldAutorotate {
    return YES;
}

iPodtouch呢？您应该使用

if（UI\u USER\u INTERFACE\u IDIOM（）==UIUserInterfaceIdiomPad）
