您可以使用UIScrollView ...

网格中的每个项目都是UIImageView，您可以将其作为子视图添加到UIScrollView。

以下代码可以在视图控制器中的viewDidLoad中进行，并假设您已在界面构建器中设置了UISCrollView，否则您需要在viewDidLoad内分配滚动视图。

代码将向具有4列的UIScrollView添加可变数量的图像项。

UIImageView *imageView = nil;

//The x and y view location coordinates for your menu items 
int x = 0, y = 0;

//The number of images you want 
int numOfItemsToAdd = 10; 

//The height and width of your images are the screen width devided by the number of columns 
int imageHeight = 320/4, imageWidth = 320/4; 

int numberOfColumns = 4; 

//The content seize needs to refelect the number of items that will be added
[scrollView setContentSize:CGSizeMake(320, imageHeight*numOfItemsToAdd];
for(int i=0; i<numOfItemsToAdd; i++){
    if(i%numberOfColumns == 0){//% the number of columns you want
        x = 0;
        if(i!=0)
            y += imageHeight;  
    }else{
        x = imageHeight;  
    }
    imageView = [[UIImageView alloc] initWithFrame: CGRectMake(x, y, imageWidth, imageHeight)];

    //set the center of the image in the scrollviews coordinate system 
    imageView.center = CGPointMake(x, y); 

    imageView.image = [UIImage imageNamed:@"my_photo.png"]; 

    //Finaly add the image to the scorll view
    [scrollView addSubview:imageView];
