ZZHotKeysMenu 自定义布局，继承自 UICollectionViewLayout
布局，集合视图，视图效果，UICollectionView
行，列间距，边距皆 可自定义设置
运行效果如下,可参考Demo：
- 设置边距等相应参数
- (UICollectionView *)hotKeyCollectView{
if (_hotKeyCollectView == nil) {
UICollectionView * collectionView = [[UICollectionView alloc]initWithFrame:self.view.bounds collectionViewLayout:self.hkLayout];
collectionView.backgroundColor = [UIColor whiteColor];
collectionView.delegate=self;
collectionView.dataSource =self;
[self.view addSubview:collectionView];
[collectionView registerClass:[ZZCollectionViewCell class] forCellWithReuseIdentifier:kCellID];
_hotKeyCollectView = collectionView;
}
return _hotKeyCollectView;
}
- (ZZHotKeysLayout *)hkLayout{
if (_hkLayout == nil) {
_hkLayout = [[ZZHotKeysLayout alloc]init];
_hkLayout.flowEdgeInset = UIEdgeInsetsMake(20, 10, 15, 40);
_hkLayout.rowSpace = 30;
_hkLayout.columSpace = 15;
_hkLayout.delegate = self;
}
return _hkLayout;
}
- 实现相应代理方法
- (CGSize)hotKeysLayout:(ZZHotKeysLayout *)layout indexPath:(NSIndexPath*)indexPath;如有问题或建议，欢迎批评指正： 简书地址联系
