我有 UIScrollView 和 UICollectionView。在 CollectionView 中有 25 张 100x100 大小的图像。当我运行我的应用程序时，它会在模拟器中显示前 12 个图像，然后我向上滚动，然后它会显示下一个图像。那不是我的问题。我想以水平模式而不是垂直模式显示图像。表示在第一页显示 12 张图像，然后水平滚动并显示下一个图像，而不是垂直显示。请告诉我该怎么做。

谢谢。

#import "Collection.h"
#import "PageViewController.h"

@interface Collection ()

@implementation Collection

@synthesize collView,selectedAlbum,img1;

    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

        // Custom initialization
    }
    return self;
}

    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.

    [self.collView registerNib:[UINib nibWithNibName:@"CollectionViewItem" bundle:nil]     forCellWithReuseIdentifier:cellReuseIdentifier];
    self.collView.backgroundColor = [UIColor blackColor];

    UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init];
    [flowLayout setItemSize:CGSizeMake(100, 100)];
    [flowLayout setMinimumLineSpacing:10];
    [flowLayout setMinimumInteritemSpacing:10];
   // [flowLayout setScrollDirection:UICollectionViewScrollDirectionVertical];
    [collView setCollectionViewLayout:flowLayout];
     collView.delegate = self;

    //Customize scrollView

    scrolView = [[UIScrollView alloc] init];
    scrolView.frame = CGRectMake(0, 0, 320, 400);
    scrolView.delegate = self;
    [self.view addSubview:scrolView];
    scrolView.contentSize = CGSizeMake(0,0,640,450);
    [scrolView addSubView:collView];

    Images = [NSArray arrayWithObjects:@"3(3).jpg",@"baby1.jpg",@"Baby2.jpg",@"Baby3.jpg",@"boat_sea_beach-normal.jpg",@"cool.jpg",@"gold-iphone-5-300912.jpg",@"life-sometimes.jpg",@"Mac Wallpapers.jpeg",@"Quotes.jpg",@"series.jpg",@"wallpaper.jpg",@"wide-9.jpg", nil];
    }

    self.navigationItem.title = selectedAlbum;

你需要用这个替换你的（注释的）滚动方向：

[flowLayout setScrollDirection:UICollectionViewScrollDirectionHorizo​​ntal];
