Question

您好我正在使用UICollectionView来显示要在数组中输入的输入值。但是，问题是我在自定义customCell中使用了UICollectionView UITableViewCell。它有滚动UITableView的时间，更改的项目数和未正确显示的项目数的问题。我尝试过很少的第三方课程，例如AFTabledCollectionView和HorizontalCollectionView。请帮帮我

//View Controller Class

 -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
     return ar.count;
 }

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
    return 1;
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *cellIdentifier = @"cell";
    CustomCells *cell = (CustomCells *)\[tableView dequeueReusableCellWithIdentifier:cellIdentifier\];
                ;
    if (cell == nil) {
        cell = [[CustomCells alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"\];
    }

    cell.lbl.text = @"Test";
    cell.textLabel.textColor=[UIColor whiteColor];
    [[NSUserDefaults standardUserDefaults] setInteger:[[self.array objectAtIndex:indexPath.row]count] forKey:@"r"];
    cell.routelbl.text=[NSString stringWithFormat:@"Route %d",(int)indexPath.row+1];
    // ... set up the cell here ...
    cell.layer.cornerRadius=5;
    cell.layer.masksToBounds=YES;
    return cell;
}

// Custom TableViewCell 

- (void)awakeFromNib {

 [self.collectionview reloadData];

 ViewController *v=[[ViewController alloc] init];

 NSLog(@"temp %d  %d ",temp,v.array.count);

 f=[NSUserDefaults standardUserDefaults];
 temp=(int)[f integerForKey:@"r"];
        ar=[[NSMutableArray alloc] init];
        [ar addObject:@"3"];
        [ar addObject:@"4"];
        [ar addObject:@"2"];
        [ar addObject:@"1"];


 UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init];
 flowLayout.scrollDirection = UICollectionViewScrollDirectionHorizontal;
        flowLayout.itemSize = CGSizeMake(70, 91.0);
     //   \[self.collectionview setCollectionViewLayout:flowLayout\];

 [self.collectionview registerNib:[UINib nibWithNibName:@"CustomCollectionViewCells" bundle:nil] forCellWithReuseIdentifier:@"cvCell2"];
 self.collectionview.layer.cornerRadius=5;
 self.collectionview.layer.masksToBounds=YES;
        // Initialization code
 }

 - (void)setSelected:(BOOL)selected animated:(BOOL)animated {
     [super setSelected:selected animated:animated\];

     // Configure the view for the selected state
 }

 -(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section{
    NSLog(@"temp %d mm ",temp);
    return temp;
}

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

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{
    temp=(int)indexPath.row;
    CustomCollectionViewCells *cell = (CustomCollectionViewCells *)\[collectionView dequeueReusableCellWithReuseIdentifier:@"cvCell2" forIndexPath:indexPath\];
    cell.layer.cornerRadius=5;
    cell.layer.masksToBounds=YES;
    return cell;
}

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath{
    NSLog(@"%d",(int)indexPath.row);
}

我面临的问题是使UICollectionView动态和离散的项目数量，以及构造数组。即添加新的UITableViewCell和UICollectionViewCell添加和删除。

Answer 1

当表中的行数设置为1并且一行中的节数设置为NSArray的计数

时，UITableView中的UICollectionView工作正常

UITableView里面的UICollectionView带有动态输入（UICollectionView）
