- (NSArray<UITableViewRowAction *> *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath{
...
}
iOS11如果仍然用以上方法处理侧滑删除功能,但是会发现侧滑无限拉伸,然后自动调用删除方法
iOS11新增了方法
- (UISwipeActionsConfiguration *)tableView:(UITableView *)tableView trailingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath API_AVAILABLE(ios(11.0)){
if (@available(iOS 11.0, *)) {
NSString *title = @"置顶";
if (indexPath.section == 0) {
title = @"取消置顶";
} else {
title = @"置顶";
}
UIContextualAction *topAction = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleNormal title:title handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {
...
// 这句很重要,退出编辑模式,隐藏左滑菜单
[tableView setEditing:NO animated:YES];
completionHandler(true);
}];
UIContextualAction *deleteAction = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleDestructive title:@"删除" handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {
// 这句很重要,退出编辑模式,隐藏左滑菜单
[tableView setEditing:NO animated:YES];
completionHandler(true);
}];
UISwipeActionsConfiguration *actions = [UISwipeActionsConfiguration configurationWithActions:@[deleteAction,topAction]];
// 禁止侧滑无线拉伸
actions.performsFirstActionWithFullSwipe = NO;
return actions;
}else{
return nil;
}
}
iOS11之前,并不会发生侧滑无线拉伸
