從滾動視圖中添加多個圖像

如果我觸摸該圖像，它會顯示一個選擇打勾（檢查）標記;如果我再次觸摸它，那麼它將被取消選擇。

我現在做這樣的：

我想它，這樣，當我說具體的圖像上點擊它會顯示一個勾號（檢查）標誌;如果我觸摸第二張照片，那麼它會顯示該圖像的一個勾號（檢查），與我們從相機膠捲中選擇圖像一樣。

所以，請儘快幫助我。

下面是我的代碼：

-(void)listimagesandanmae 
{ 

int myFavV = [favCompcamelIDArr count]; 
for (int i = 0; i < myFavV; i++) 
{ 
    CGFloat xOrigin = i * 100; 


    favimageView = [[UIImageView alloc] initWithFrame:CGRectMake(xOrigin+20,10,70,70)]; 

    favimageView.layer.cornerRadius = favimageView.frame.size.width/2; 
    favimageView.clipsToBounds = YES; 

    //  imageView.layer.cornerRadius = 60; 
    //  imageView.clipsToBounds = YES; 
    favimageView.tag=i; 

    NSInteger tag = favimageView.tag; 
    // then do what you want with this 

    if (([favCompcamelIDArr count] >0)) { 


    } 

    favnamelistingLbl=[[UILabel alloc]initWithFrame:CGRectMake(xOrigin+23,90,90,27)]; 

    favnamelistingLbl.textAlignment = NSTextAlignmentCenter; 

    favnamelistingLbl.tag=i; 


    NSLog(@"%lu",(unsigned long)[favcompnsmeArr count]); 

    if (([favCompcamelIDArr count] > 0)) { 

     favnamelistingLbl.text=[favcompnsmeArr objectAtIndex:i]; 

    } 

    [_selectCamelFav addSubview:favnamelistingLbl]; 

    UITapGestureRecognizer *tappedmyFav = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tappedmyFav:)]; 
    tappedmyFav.numberOfTapsRequired = 1; 

    [favimageView addGestureRecognizer:tappedmyFav]; 
    NSLog(@"%ld",(long)tag); 

    NSString *[email protected]"http://192.8.1.42:/da/"; 
    NSString *urStCam1=[urStCam stringByAppendingString:[favcompictureArr objectAtIndex:i]]; 

    NSString *urStCam2= [urStCam1 stringByReplacingOccurrencesOfString:@"\n" withString:@""]; 


    [caArray addObject:urStCam2]; 
    NSLog(@"%@",caArray); 

    NSURL *newUrl=[NSURL URLWithString:[caArray objectAtIndex:i]]; 
    NSData *imageDatash = [NSData dataWithContentsOfURL:newUrl]; 
    UIImage *image123 = [UIImage imageWithData:imageDatash scale:2.0]; 
    [favimageView setImage:image123]; 

    [_selectCamelFav addSubview:favimageView]; 
    favimageView.userInteractionEnabled = YES; 


} 
_selectCamelFav.contentSize = CGSizeMake(myFavV * 210, 171); 

[_indicatorA startAnimating]; 
_indicatorA.hidden=YES; 


} 

    - (void)tappedmyFav:(UITapGestureRecognizer*)tap 
{ 
UITapGestureRecognizer *gesture = (UITapGestureRecognizer *) tap; 

    }

爲什麼不使用'UICollectionView'或'UITableView'。它會容易得多。 – Ryan 2015-03-20 00:29:59

你應該繼承的UIView。然後添加UIImageView，UILabel（複選標記）和一個屬性來控制是否選擇了UIView。同時添加點擊手勢處理程序（點擊時選擇=！）

要搜索選擇哪個視圖，請搜索滾動視圖以查找'selected'UIView對象。或者你可以維護自己的列表，一旦對象被選中/取消選中，這樣你就不需要搜索所有的對象。
