UICollectionViewCell重用叠加出问题的解决
首先创建一个可变数组,用来存放Cell的唯一标示符
// 用来存放Cell的唯一标示符
@property (nonatomic, strong) NSMutableDictionary *cellDic;
#warning 别忘了初始化哟
self.cellDic = [[NSMutableDictionary alloc] init];
在cellForItemAtIndexPath:这个方法中作相应的一些处理即可,代码如下
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
// 每次先从字典中根据IndexPath取出唯一标识符
NSString *identifier = [_cellDic objectForKey:[NSString stringWithFormat:@"%@", indexPath]];
// 如果取出的唯一标示符不存在,则初始化唯一标示符,并将其存入字典中,对应唯一标示符注册Cell
if (identifier == nil) {
identifier = [NSString stringWithFormat:@"%@%@", DayCell, [NSString stringWithFormat:@"%@", indexPath]];
[_cellDic setValue:identifier forKey:[NSString stringWithFormat:@"%@", indexPath]];
// 注册Cell
[self.collectionView registerClass:[CalendarCollectionViewCell class] forCellWithReuseIdentifier:identifier];
}
CalendarCollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
// 此处可以对Cell做你想做的操作了...
return cell;
}
