ios – UICollectionview是空的

概述嗨我创建了一个UIViewController,我添加了一个带CustomCell的UICollectionView.然后,我为单元格创建了一个uicollectionviewcell类.最后在storybord本身设置委托和数据源.但它显示空页.如下图所示 码： - (void)viewDidLoad{ [super viewDidLoad]; self.collectionv 嗨我创建了一个UIVIEwController,我添加了一个带CustomCell的UICollectionVIEw.然后,我为单元格创建了一个uicollectionvIEwcell类.最后在storybord本身设置委托和数据源.但它显示空页.如下图所示

码：

- (voID)vIEwDIDLoad{    [super vIEwDIDLoad];    self.collectionvIEw = _collectionvIEw;    self.collectionvIEw.dataSource = self;    self.collectionvIEw.delegate = self;    speakersImages=[[NSMutableArray alloc]init];    // Do any additional setup after loading the vIEw,typically from a nib.    imageLabels=[[NSMutableArray alloc]initWithObjects:@"RB Forum 2013",@"Agenda",@"Speakers",@"Contact",@"Map",@"Websites",@"@Responsible Biz",@"Partners",@"Sustainability",nil];    imagePaths=[[NSMutableArray alloc]initWithObjects:[UIImage imagenamed:@"RBform.png"],[UIImage imagenamed:@"agenda.png"],[UIImage imagenamed:@"speakers.png"],[UIImage imagenamed:@"contact.png"],[UIImage imagenamed:@"map.png"],[UIImage imagenamed:@"website.png"],[UIImage imagenamed:@"twitter.png"],[UIImage imagenamed:@"partners.png"],[UIImage imagenamed:@"sustainability.png"],nil];    [self.collectionvIEw registerClass:[NewCell class] forCellWithReuseIDentifIEr:@"Cell"];}- (NSInteger)numberOfSectionsInCollectionVIEw:(UICollectionVIEw *)collectionVIEw{    return 1;}- (NSInteger)collectionVIEw:(UICollectionVIEw *)collectionVIEw     numberOfItemsInSection:(NSInteger)section{    return [imageLabels count];}//THE BELOW DELEGATE METHOD DOES NOT GET CALLED!- (voID)dIDReceiveMemoryWarning{    [super dIDReceiveMemoryWarning];    // dispose of any resources that can be recreated.}- (UICollectionVIEwCell *)collectionVIEw:(UICollectionVIEw *)collectionVIEw cellForItemAtIndexPath:(NSIndexPath *)indexPath{    // we're going to use a custom UICollectionVIEwCell,which will hold an image and its label    //    static Nsstring *CellIDentifIEr = @"Cell";    NewCell *cell = [collectionVIEw dequeueReusableCellWithReuseIDentifIEr:CellIDentifIEr forIndexPath:indexPath];    // make the cell's Title the actual NSIndexPath value    cell.labels.text = [Nsstring stringWithFormat:@"%@",[imageLabels objectAtIndex:indexPath.row]];    // load the image for this cell    NSLog(@"%@",imageLabels);    //Nsstring *imagetoLoad = [Nsstring stringWithFormat:@"%d.JPG",indexPath.row];    //    cell.image.image = [UIImage imagenamed:imagetoLoad];    cell.images.image = [imagePaths objectAtIndex:indexPath.row];    return cell;}

解决方法 解决方案已删除
[self.collectionvIEw registerClass：[NewCell class] forCellWithReuseIDentifIEr：@“Cell”];

在storybord我们不需要这个
