## Requirements

## Installation

LBAttributeLayout is available through [CocoaPods](https://cocoapods.org). To install
it, simply add the following line to your Podfile:

```ruby
pod 'LBAttributeLayout'

#使用方法
- (UICollectionView *)collectionView
{
    if (!_collectionView) {
        LBAttributeLayout *layout = [[LBAttributeLayout alloc] initWithConfiguration:self.configuration];
        layout.delegate = self;
        _collectionView = [[UICollectionView alloc] initWithFrame:CGRectMake(0, 100, CGRectGetWidth(self.view.bounds), 200) collectionViewLayout:layout];
        [_collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:NSStringFromClass([UICollectionViewCell class])];
        _collectionView.dataSource = self;
        _collectionView.delegate = self;
    }
    return _collectionView;
}

- (LBAttributeLayoutConfiguration *)configuration
{
    if (!_configuration) {
        _configuration = [[LBAttributeLayoutConfiguration alloc] init];
    }
    return _configuration;
}

#实现 LBAttributeLayoutDelegate 协议方法
#pragma mark - LBAttributeLayoutDelegate

- (CGFloat)cellWidthForItemAtIndex:(NSInteger)index
{
    NSString *content = self.dataSource[index];
    CGFloat width = [content sizeWithAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:18]}].width;
    return width + 30;
}

#计算内容高度

NSMutableArray *widthArray = [NSMutableArray array];
for (int i = 0; i < self.dataSource.count; i ++) {
    CGFloat width = [self cellWidthForItemAtIndex:i];
    [widthArray addObject:@(width)];
}
CGFloat height = [LBAttributeLayout contentHeightWithConfiguration:self.configuration cellWidthArray:widthArray];
self.collectionView.frame = CGRectMake(0, 100, CGRectGetWidth(self.view.bounds), height);

```
