iPhone SDK：设置UISearchDisplayController的表视图的大小 [英] iPhone SDK: Setting the size of UISearchDisplayController's table view

问题描述

我的应用程序的表格视图没有占据整个屏幕的高度，因为我在底部允许横幅为50px。

My app's table view does not occupy the full screen height, as I've allowed 50px at the bottom for a banner.

当我开始输入搜索内容时bar，搜索结果表视图更大;它填充搜索栏和标签栏之间的所有可用屏幕空间。这意味着最后一个搜索结果被横幅遮挡。

When I begin typing in the search bar, the search results table view is larger; it fills all available screen space between the search bar and the tab bar. This means that the very last search result is obscured by the banner.

如何指定UISearchDisplayController使用的表视图的大小？我可以看到没有边界或框架属性。

How do I specify the size of the table view used by UISearchDisplayController? There's no bounds or frame property that I can see.

编辑添加屏幕截图：

这是在IB中设置表格视图的方式。它比合成标签栏短50px。

This is how the table view is set up in IB. It ends 50px short of the synthesized tab bar.

这是内容正常显示的方式。我已经滚到了最底层。

This is how content displays normally. I've scrolled to the very bottom here. alt text http://iphone.lightwood.net/StackOverflow/gstableviewatbottom.png

这是搜索时显示的方式。我再次滚动到最底层。如果我停用横幅广告，我会看到搜索显示表向右展开到标签栏。

This is how it displays when searching. Again, I've scrolled to the very bottom. If I disable the banner ad, I can see that the search display table spreads right down to the tab bar.

推荐答案

解决这个问题的关键是找出何时更改表格视图的几何形状。调用：

The key to solving this one was finding out when to change the geometry of the table view. Calling:

[self.searchDisplayController.searchResultsTableView setFrame:someframe];

是徒劳的。答案是这个委托方法：

after creating the UISearchDisplayController was futile. The answer was this delegate method:

-(void)searchDisplayController:(UISearchDisplayController *)controller didShowSearchResultsTableView:(UITableView *)tableView {
    tableView.frame = someframe;
}

注意，我也试过 -searchDisplayController：didLoadSearchResultsTableView 但在那里没有任何好处。你必须等到显示它才能调整大小。

Note, I had also tried -searchDisplayController:didLoadSearchResultsTableView but it did no good in there. You have to wait until it's displayed to resize it.

另请注意，如果你只是指定 tableView.frame = otherTableView.frame ，搜索结果表与其对应的搜索栏重叠，因此无法清除或取消搜索！

Also note that if you simply assign tableView.frame = otherTableView.frame, the search results table overlaps its corresponding search bar, so it is impossible to clear or cancel the search!

我的最终代码如下所示：

My final code looked like this:

-(void)searchDisplayController:(UISearchDisplayController *)controller didShowSearchResultsTableView:(UITableView *)tableView {

    CGRect f = self.masterTableView.frame;  // The tableView the search replaces
    CGRect s = self.searchDisplayController.searchBar.frame;
    CGRect newFrame = CGRectMake(f.origin.x,
                                 f.origin.y + s.size.height,
                                 f.size.width,
                                 f.size.height - s.size.height);

    tableView.frame = newFrame;
}
