iPhone中的UIScrollView？

Question

我正在iPhone應用程序中工作，使用UIScrollView設置爲水平，在UIScrollView中添加5個圖像，並且其工作正常。 （我想在開放時間顯示第二張圖片）然後，我試着在屏幕顯示時，在第二張圖片顯示時。但我想我的最好水平，但我沒有做到這一點，請任何一個幫助我

在此先感謝

我嘗試這樣做：

UIScrollView *scroll1 = [[UIScrollView alloc] initWithFrame:CGRectMake(10, 45, 300, 360)]; 
    scroll1.contentSize=CGSizeMake(2700, 360); 
    [scroll1 setShowsHorizontalScrollIndicator:NO]; 
    scroll1.pagingEnabled=YES; 
    [self.view addSubview:scroll1]; 

    UIImageView *SlideImage = [[UIImageView alloc]initWithFrame:CGRectMake(0,0, 300, 360)]; 
    SlideImage.image=[UIImage imageNamed:@"img1.png"]; 
    SlideImage.backgroundColor=[UIColor clearColor]; 
    [scroll1 addSubview:SlideImage]; 

    UIImageView *SlideImage1 = [[UIImageView alloc]initWithFrame:CGRectMake(300,0, 300, 360)]; 
    SlideImage1.image=[UIImage imageNamed:@"img2.png"]; 
    SlideImage1.backgroundColor=[UIColor clearColor]; 
    [scroll1 addSubview:SlideImage1]; 

    UIImageView *SlideImage2 = [[UIImageView alloc]initWithFrame:CGRectMake(600,0, 300, 360)]; 
    SlideImage2.image=[UIImage imageNamed:@"img3.png"]; 
    SlideImage2.backgroundColor=[UIColor clearColor]; 
    [scroll1 addSubview:SlideImage2]; 

    UIImageView *SlideImage3 = [[UIImageView alloc]initWithFrame:CGRectMake(900,0, 300, 360)]; 
    SlideImage3.image=[UIImage imageNamed:@"img4.png"]; 
    SlideImage3.backgroundColor=[UIColor clearColor]; 
    [scroll1 addSubview:SlideImage3]; 

    UIImageView *SlideImage4 = [[UIImageView alloc]initWithFrame:CGRectMake(1200,0, 300, 360)]; 
    SlideImage4.image=[UIImage imageNamed:@"img5.png"]; 
    SlideImage4.backgroundColor=[UIColor clearColor]; 
    [scroll1 addSubview:SlideImage4]; 

    UIImageView *SlideImage5 = [[UIImageView alloc]initWithFrame:CGRectMake(1500,0, 300, 360)]; 
    SlideImage5.image=[UIImage imageNamed:@"img6.png"]; 
    SlideImage5.backgroundColor=[UIColor clearColor]; 
    [scroll1 addSubview:SlideImage5];

試試這個

[scroll1 setContentOffset:CGPointMake(300, 0) animated:FALSE];
