ios - 如何扩展单个特定部分？
<p><p>我使用了名为“ExpandableTableView”的第三方可扩展表格 View ，当我想在我的 View 中使用自定义按钮扩展特定的单个部分时。我的代码片段是:</p>
<pre><code>UIView *view=Gesture.view;
isFirsTime=NO;
//NSLog(@"%ld",(long)view.tag);
for (int h=0; h<dicAll.count; h++)
{
NSString *strRegisterId=[[valueForKey:@"projectdefectid"]objectAtIndex:h];
NSString *strBtnTag=;
if ()
{
btnIndex=h;
// NSLog(@"%ld",(long)btnIndex);
isTappedMarker=YES;
}
}
NSMutableArray *indexPaths=[init];
];
NSLog(@"%@",arrDefectImages);
NSLog(@"numberOfRowsInSection: %ld",(long));
;
;
;
</code></pre>
<p>btnIndex 是我要扩展的节号。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我通过使用这个实现了类似的目标:</p>
<pre><code>func didTapOnHeader(tapGesture: UITapGestureRecognizer) {
let view = tapGesture.view as! ViewHeader
// collapse if already expended.
if view.tag == self.dataBinder.selectedSection {
//collaps the section
self.dataBinder.selectedSection = nil
self.tableView.reloadSections(NSIndexSet(index:view.tag), withRowAnimation: UITableViewRowAnimation.Automatic)
}else {
// collapse last selected section, at a time one section should be selected.
self.dataBinder.selectedSection = nil
self.tableView.reloadData()
//expand plan details
self.dataBinder.selectedSection = view.tag
self.tableView.reloadSections(NSIndexSet(index:view.tag), withRowAnimation: UITableViewRowAnimation.Automatic)
}
}
func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let view = ViewHeader.instanceFromNib()
view.tag = section
let gesture = UITapGestureRecognizer(target: self, action: #selector(ViewController.didTapOnHeader(_:)))
view.addGestureRecognizer(gesture)
//### Assignment ###
view.planDescriptionLabel.text = plan.planDescription
return view
}
</code></pre>
<p>这将关闭以前选择的部分，并且每次只展开一个部分。 </p></p>
