Oto podejście wziąłbym do Zrób to.
@property (nonatomic, strong) NSIndexPath *selectedIndexPath;
Ustaw właściwość typu NSIndexPath na kontrolerze, aby zapisać wybraną ścieżkę indeksu.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
self.selectedIndexPath = indexPath;
[tableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation: UITableViewRowAnimationNone];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if ([indexPath compare:self.selectedIndexPath] == NSOrderedSame) {
// Create your custom cell here and return it.
}
else {
// Should create a normal cell and return it.
}
}
Dokładnie. Zauważ też, że prawdopodobnie chcesz odznaczyć. Oto pełny kod w Swift. Użyj selectedIndexPath w cellForRowAtIndexPath stosownie do potrzeb.
// Wybranie TableViewController import UIKit
klasy SelectingTableViewController: UITableViewController
{ wewnętrzny selectedIndexPath var: NSIndexPath? = zero
override func viewDidLoad()
{
super.viewDidLoad()
tableView.estimatedRowHeight = 68.0
tableView.rowHeight = UITableViewAutomaticDimension
self.clearsSelectionOnViewWillAppear = false;
}
override func tableView
(tableView:UITableView, didSelectRowAtIndexPath indexPath:NSIndexPath)
{
print("did select....")
// in fact, was this very row selected,
// and the user is clicking to deselect it...
// if you don't want "click a selected row to deselect"
// then on't include this clause.
if selectedIndexPath == indexPath
{
print("(user clicked on selected to deselect)")
selectedIndexPath = nil
tableView.reloadRowsAtIndexPaths(
[indexPath],
withRowAnimation:UITableViewRowAnimation.None)
tableView.deselectRowAtIndexPath(indexPath, animated:false)
return
}
// in fact, was some other row selected??
// user is changing to this row? if so, also deselect that row
if selectedIndexPath != nil
{
let pleaseRedrawMe = selectedIndexPath!
// (note that it will be drawn un-selected
// since we're chaging the 'selectedIndexPath' global)
selectedIndexPath = indexPath
tableView.reloadRowsAtIndexPaths(
[pleaseRedrawMe, indexPath],
withRowAnimation:UITableViewRowAnimation.None)
return;
}
// no previous selection.
// simply select that new one the user just touched.
// note that you can not use Apple's willDeselectRowAtIndexPath
// functions ... because they are freaky
selectedIndexPath = indexPath
tableView.reloadRowsAtIndexPaths(
[indexPath],
withRowAnimation:UITableViewRowAnimation.None)
}
}
