“以编程方式”;闪烁;UITableViewCell将背景色设置为白色

“以编程方式”;闪烁;UITableViewCell将背景色设置为白色,uitableview,ios7,uigesturerecognizer,Uitableview,Ios7,Uigesturerecognizer,我在我的UICollectionView中设置了ui长按手势识别器,它调用 - (void)longPress:(UILongPressGestureRecognizer *)gesture { if (gesture.state == UIGestureRecognizerStateBegan) { CGPoint point = [gesture locationInView:self.collectionView]; NSIndexPath *ind

我在我的
UICollectionView
中设置了
ui长按手势识别器
,它调用

- (void)longPress:(UILongPressGestureRecognizer *)gesture {
    if (gesture.state == UIGestureRecognizerStateBegan) {
        CGPoint point = [gesture locationInView:self.collectionView];
        NSIndexPath *indexPath = [self.collectionView indexPathForItemAtPoint:point];
        if (indexPath) {
            self.manager.currentLongPressIndex = indexPath.row;
            [self showPopover];
        }
    }
}
方法中显示的
uipover
具有
UITableView
。我的目标是“闪存”(选择然后取消选择
UITableViewCell
)并滚动显示它。我就是这样做的:

- (void)viewDidLoad {
    [super viewDidLoad];
    // get the current index path
    NSIndexPath *path = [NSIndexPath indexPathForRow:self.manager.currentLongPressIndex inSection:0];
    // set flag
    self.cellIsFlashing = YES;
    // select cell
    [self.tableView selectRowAtIndexPath:path animated:YES scrollPosition:UITableViewScrollPositionMiddle];
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    if (self.cellIsFlashing == NO) {
        [self.viewController.collectionView scrollToItemAtIndexPath:indexPath atScrollPosition:UICollectionViewScrollPositionTop animated:YES];
    } else {
        self.cellIsFlashing = NO;
    }
    [self.tableView deselectRowAtIndexPath:indexPath animated:YES];
}
这是可行的,但选定单元格的背景色变为白色,闪光效果看起来不太好,看起来根本没有设置动画


尝试延迟取消选择过程:

-(void)deselectRow:(NSIndexPath *)indexPath {
    [self.tableView deselectRowAtIndexPath:indexPath animated:YES];
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    ... // your code here

    // call the deselect method with 0.3 second delay
    [self performSelector:@selector(deselectRow:) withObject:indexPath afterDelay:0.3f];
}

不确定这是否可行,但值得一试。

通过将单元格选择代码从
viewDidLoad
更改为
ViewDidDisplay:animated:
