在ios中的同一屏幕上的多个collectionviews

Question

我在我的应用程序中使用PSUICollectionView，其中与图像大拇指画廊加载水平滚动视图。 现在我需要两个更多的collectionviews（画廊）来显示两种其他类型的图片。

任何人都可以请帮我吗？ 在此先感谢。

Answer 1

简单。像添加其他UIView一样添加视图。正确设置框架，他们应该工作。

为每个人保留一个插座，然后你可以检查他们中哪一个正在调用委托/数据源方法。

Answer 2

我把它加在委托和数据源方法的一些代码行如下工作 -

// setting tag 

    [self.imageCollection setTag:1]; 

    [self.finishImageCollection setTag:2]; 

    [self.prevImageCollection setTag:3];

编译标记集合视图数据源

- (NSString *)formatIndexPath:(NSIndexPath *)indexPath { 
     return [NSString stringWithFormat:@"%ld", (long)indexPath.row+1]; 
    } 

    // Populating cells 
    - (PSUICollectionViewCell *)collectionView:(PSUICollectionView *)collectionView  cellForItemAtIndexPath:(NSIndexPath *)indexPath { 
    ImageGridCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath]; 
    if(collectionView.tag==1){ 
    cell.statusImage.image= [UIImage imageNamed:@"checked.png"]; 
    cell.imageThumb.image = [self.startImages objectAtIndex:indexPath.row]; 
    } 

    if(collectionView.tag==2){ 
    cell.statusImage.image= [UIImage imageNamed:@"checked.png"]; 
    cell.imageThumb.image = [self.finishImages objectAtIndex:indexPath.row]; 
    } 

    if(collectionView.tag==3){ 
    cell.statusImage.image= [UIImage imageNamed:@"checked.png"]; 
    cell.imageThumb.image = [self.prevImages objectAtIndex:indexPath.row]; 
    } 
    return cell; 
    } 

    - (NSInteger)collectionView:(PSUICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section { 
    int imgCount; 
    if(collectionView.tag==1) 
    { 
    [self loadStartPictures]; 
    imgCount=self.startImages.count; 
    } 
    if(collectionView.tag==2) 
    { 
    [self loadFinishPictures]; 
    imgCount=[self.finishImages count]; 
    } 
    if(collectionView.tag==3) 
    { 
    [self loadSupervisorPictures]; 
    imgCount=[self.prevImages count]; 
    } 
    return imgCount; 
    } 


    #pragma mark - 
    #pragma mark Collection View Delegate 

    - (void)collectionView:(PSTCollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath 
    { 
    self.allImages=[[NSMutableArray alloc]init]; 
    UIImage *imageAtIndexPath; 
    NSLog(@"Delegate cell %@ : SELECTED", [self formatIndexPath:indexPath]); 
    ImageGridCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath]; 
    cell.label.backgroundColor=[UIColor underPageBackgroundColor]; 

    if(collectionView.tag==1){ 
    imageAtIndexPath=[self.startImages objectAtIndex:indexPath.row]; 
    } 
    if(collectionView.tag==2){ 
    imageAtIndexPath=[self.finishImages objectAtIndex:indexPath.row]; 
    } 
    if(collectionView.tag==3){ 
    imageAtIndexPath=[self.supervisorImages objectAtIndex:indexPath.row]; 
    } 
}
