UIViewController控制器无法识别委托

Question

我第一次创建UIControlerView时，似乎从未激活过代理。请告诉我哪里出错了。

谢谢！ 顺便说一句，我通过从故事板中拖出来创建IBOutlet ......

·H

#import <UIKit/UIKit.h>

@interface CollectionController : UIViewController<UICollectionViewDelegate,UICollectionViewDataSource>

@property (weak, nonatomic) IBOutlet UICollectionView *controllerTableView;

@end

的.m

#import "CollectionController.h"
#import "CollectionVIewCell.h"

@interface CollectionController ()

@end

@implementation CollectionController

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[self controllerTableView]setDelegate:self];
    [[self controllerTableView]setDataSource:self];
    // Do any additional setup after loading the view.
}
-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section{
    return 10;
}

-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView{
    return 1;
}


-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

    static NSString *cellIdentifier=@"Cell";
    CollectionVIewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];

    cell.labelDisplay.text=@"hi";
    //set up data in images

    return cell;
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

Answer 1

尝试在xib中而不是在代码中连接UICollectionView的委托和数据源。

Answer 2

由于“弱”属性，您的controllerTableView是否可能被取消分配？尝试使用“强”，看看是否有帮助。

Answer 3

我在这里推错了，应该是

CollectionController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"CollectionController"];
    [self.navigationController pushViewController:controller animated:YES];

Answer 4

检查是否选中了这个继承模块
