Objective-c-2动画不能一起工作

我正在尝试创建一个动画,当我从表格视图中单击一个单元格时:

1)我创建了这个单元格的克隆并将其发送到我的视图顶部; 2)将我的tableview发送到左侧

但我不能让他们一起工作。使用下面的代码,我将单元格的动画放到顶部但我的tableview保持原样(不向左移动):

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    //cloning UITableViewCell view for later work
    NSData *tempArchiveView = [NSKeyedArchiver archivedDataWithRootObject:[tableView cellForRowAtIndexPath:indexPath]];
    UIView *headerView = [NSKeyedUnarchiver unarchiveObjectWithData:tempArchiveView];

    headerView.frame = CGRectMake(0,
                                  headerView.frame.origin.y,
                                  headerView.frame.size.width,
                                  headerView.frame.size.height);
    //adding to the main view
    [self.view insertSubview:headerView aboveSubview:self.newsTableView];

    [UIView animateWithDuration:0.5 animations:^{
        //move my tableview to the left
        self.newsTableView.center = CGPointMake(-300, tableView.center.y);

        //send my header to the top starting from 
        headerView.frame = CGRectMake(0, 0, headerView.frame.size.width, headerView.frame.size.height);
    }];

}

我意识到当我删除这一行时:

[self.view insertSubview:headerView aboveSubview:self.newsTableView];

表格视图按我的要求向左移动,但我不再有单元格动画

问候!

答案 0 :(得分:0)

我明白了:

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

    //clone tableview cell for later work
    NSData *tempArchiveView = [NSKeyedArchiver archivedDataWithRootObject:[tableView cellForRowAtIndexPath:indexPath]];

    self.headerView = [NSKeyedUnarchiver unarchiveObjectWithData:tempArchiveView];

    //save te frame in relation to tableview's supervir
    CGRect cellPositionOnWindow = [tableView rectForRowAtIndexPath:indexPath];
    CGRect rectInSuperview = [tableView convertRect:cellPositionOnWindow toView:[tableView superview]];

    apply this frame to the clone
    self.headerView.frame = rectInSuperview;
    [self.view addSubview:self.headerView];


    [UIView animateWithDuration:0.5 animations:^{
        //I decided to move the bounds instead of the frame
        self.view.bounds = CGRectMake(320, 
                                      self.view.frame.origin.y, 
                                      tableView.frame.size.width,
                                      tableView.frame.size.height);

        self.headerView.frame = CGRectMake(320,
                                           0,
                                           self.headerView.frame.size.width,
                                           self.headerView.frame.size.height);
    }];
}

它工作得很好,我可以做到包括另一个横向视图的效果。
