如何通过触摸无限量的UIImages来创建和控制？

Question

我需要一个贴纸页面，有人可以随意引入任意数量的贴纸并放在页面上。用户应该可以移动任何贴纸。我只能移动引入的贴纸，而不是viewDidLoad方法带来的保存贴纸。

开始接触：

UITouch * touch = [[event allTouches] anyObject];     CGPoint location = [touch locationInView：touch.view];

if (location.x < image0.frame.size.width + image0.frame.origin.x && location.y < image0.frame.size.height + image0.frame.origin.y && location.x > image0.frame.origin.x && location.y > image0.frame.origin.y)
{
    [image0 removeFromSuperview];

    image0 = nil;
    image0 =[[UIImageView alloc] initWithFrame:CGRectMake(location.x - 25,location.y-25, 50, 50)];
    image0.image =[UIImage imageNamed:sticker.stickerFilePath];

    [self.view addSubview:image0];


}

在viewDidLoad中，正在引入类中保存的贴纸：

stickerArray = [self loadStickerData];     allStickers = [[NSMutableArray alloc] initWithCapacity：10];

    sticker=[self.childClass.stickerInfo objectAtIndex:0];

    float x = sticker.xLocationOfSticker, y = sticker.yLocationOfSticker, w =sticker.stickerWidth, h=sticker.stickerHeight;
    image0 =[[UIImageView alloc] initWithFrame:CGRectMake(x,y,w,h)];
    image0.image=[UIImage imageNamed:sticker.stickerFilePath];
    [self.view addSubview:image0];
