[英]UICollectionView Vertical showing half the cell in the end
我有collectionView。 它垂直显示单元格。
首先,collectionView看起来像这样
最后看起来像这样
所以它基本上不会最终显示整个单元格的集合类的代码是
#import "ViewController.h"
@interface ViewController ()
@property (weak, nonatomic) IBOutlet UICollectionView *collectionView;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - CollectionView Datasource
- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView{
return 1;
}
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section{
return 9;
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{
ViewControllerCollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];
return cell;
}
@end
您必须在情节提要中指定单元格大小。
-(CGSize)collectionView:(UICollectionView *)collectionView布局:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {
float width = 100; //change to your needed width
float height = 100; //change to your needed height
return CGSizeMake(width, height);
}
试试这个代码,它将帮助您
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
return 9;
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *identifier = @"cellIdentifier";
UICollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
return cell;
}
并在属性检查器中更改标识符名称,如下图所示:
