UiCollectionview允許單個選擇特定單元格

Question

在集合視圖中我選擇了一個單元格，但它被選中了多個單元格。

- (UICollectionViewCell *)collectionView:(UICollectionView  *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{ 
CustomCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath]; 
    cell.Selectitems.tag=indexPath.row; 
[cell.Selectitems addTarget:self action:@selector(selectitem:) forControlEvents:UIControlEventTouchUpInside]; 
} 
-(void)selectitem :(UIButton *)sender{ 
if ([sender isSelected]) { 
    [sender setSelected: NO]; 
    cell.check = YES; 
    [cell.Selectitems setBackgroundImage:[UIImage imageNamed:@"product-uncheck.png"] forState:UIControlStateNormal]; 
}else{ 
     [sender setSelected: YES]; 
     cell.check = YES; 
     [cell.Selectitems setBackgroundImage:[UIImage imageNamed:@"product-check.png"] forState:UIControlStateNormal]; 
} 
}

Answer 2

當你點擊你是不是在第一小區改變圖像的第二單元。

所以一定要確保，如果你點擊任何細胞改變形象product-check.png和以前的細胞圖像作爲product-uncheck.png

Answer 3

做這樣當按鈕被按下

-(void)selectitem :(UIButton *)sender{ 

//Get Index path from Button Tag 
    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:sender.tag inSection:0]; 

// get Cell instance and than do whatever you want with Cell items 
CustomCell *cell = *cell = [self.collectionView cellForItemAtIndexPath:indexPath]; 

if ([cell.Selectitems isSelected]) { 
    [cell.Selectitems setSelected: NO]; 
    cell.check = YES; 
    [cell.Selectitems setBackgroundImage:[UIImage imageNamed:@"product-uncheck.png"] forState:UIControlStateNormal]; 
}else{ 
     [cell.Selectitems setSelected: YES]; 
     cell.check = YES; 
     [cell.Selectitems setBackgroundImage:[UIImage imageNamed:@"product-check.png"] forState:UIControlStateNormal]; 
} 
} 

我希望這將解決您的問題。
