本文介绍了UICollectionView的动态单元格宽度取决于标签宽度的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个UICollectionView，它从可重复使用的单元格加载单元格，其中包含标签。数组为该标签提供内容。我可以使用sizeToFit轻松调整标签宽度，具体取决于内容宽度。但是我不能让单元符合标签。
I have a UICollectionView, that loads cells from reusable cell, which contains label. An array provides content for that label. I can resize label width depending on content width easily with sizeToFit. But I cannot make cell to fit label.
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;
}
推荐答案
在 sizeForItemAtIndexPath 返回文本的大小
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath{
return [(NSString*)[arrayOfStats objectAtIndex:indexPath.row] sizeWithAttributes:NULL];
}
