我有一个UICollectionView,它从包含标签的可重用单元格加载单元格。数组为该标签提供内容。我可以使用sizeToFit轻松根据内容宽度调整标签宽度。但是我无法制作适合标签的单元格。
这是代码
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
arrayOfStats = @[@"time:",@"2",@"items:",@"10",@"difficulty:",@"hard",@"category:",@"main"];
}
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection: (NSInteger)section{
return [arrayOfStats count];
}
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath{
return CGSizeMake(??????????);
}
- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView{
return 1;
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{
Cell *cell = (Cell *) [collectionView dequeueReusableCellWithReuseIdentifier:@"qw" forIndexPath:indexPath];
cell.myLabel.text = [NSString stringWithFormat:@"%@",[arrayOfStats objectAtIndex:indexPath.item]];
// make label width depend on text width
[cell.myLabel sizeToFit];
//get the width and height of the label (CGSize contains two parameters: width and height)
CGSize labelSize = cell.myLbale.frame.size;
NSLog(@"\n width = %f height = %f", labelSize.width,labelSize.height);
return cell;
}
