列表与九宫格 随意切换
1，用一个collectionView即可
2，设置BOOL来辨别是列表形式还是九宫格
3，根据BOOL值，用这个方法设置所要显示的每个cell的宽高
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
if (_isGrid)
{
return CGSizeMake(([UIScreen mainScreen].bounds.size.width - 10) / 2, ([UIScreen mainScreen].bounds.size.width - 6) / 2 + 40);
} else
{
return CGSizeMake([UIScreen mainScreen].bounds.size.width, ([UIScreen mainScreen].bounds.size.width - 6) / 4 + 20);
}
}
4，cell里，设置cell根据BOOL值的变化改变布局，然后设置数据
- (void)setIsGrid:(BOOL)isGrid
{
_isGrid = isGrid;
if (isGrid)
{
NSLog(@"11111111111111111");
_imageV.frame = CGRectMake(5, 5, self.bounds.size.width - 60, self.bounds.size.width - 60);
_titleLabel.frame = CGRectMake(5, self.bounds.size.width - 45, ([UIScreen mainScreen].bounds.size.width - 4)/2, 40);
_priceLabel.frame = CGRectMake(5, self.bounds.size.width + 5,([UIScreen mainScreen].bounds.size.width - 4)/2, 20);
}else {
NSLog(@"222222222222222222");
_imageV.frame = CGRectMake(5, 5, self.bounds.size.height - 10, self.bounds.size.height - 10);
_titleLabel.frame = CGRectMake(self.bounds.size.height + 10, 0,([UIScreen mainScreen].bounds.size.width - 4)/2, self.bounds.size.height - 20);;
_priceLabel.frame = CGRectMake(self.bounds.size.height + 10, self.bounds.size.height - 30, ([UIScreen mainScreen].bounds.size.width - 4)/2, 20);;
}
}
- (void)setModel:(NSDictionary *)model
{
_model = model;
_imageV.image = [UIImage imageNamed:@"1.png"];
_titleLabel.text = @"你的發表卡吉巴基看吧阿里舉辦";
_priceLabel.text = @"123123";
}
