我正在使用 SWRevealViewController 构建侧边栏菜单。从菜单（UITableView）中选择一个元素时，我有这种方法来选择正确的控制器。segue 标识符/名称在情节提要中配置。
- (void) prepareForSegue: (UIStoryboardSegue *) segue sender: (id) sender
{
NSLog(@"Tapped");
// Set the title of navigation bar by using the menu items
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
UINavigationController *destViewController = (UINavigationController*)segue.destinationViewController;
destViewController.title = [[_menuItems objectAtIndex:indexPath.row] capitalizedString];
// Set the photo if it navigates to the PhotoView
if ([segue.identifier isEqualToString:@"showToday"]) {
[segue destinationViewController];
}
if ([segue.identifier isEqualToString:@"showCountries"]) {
[segue destinationViewController];
}
if ( [segue isKindOfClass: [SWRevealViewControllerSegue class]] ) {
SWRevealViewControllerSegue *swSegue = (SWRevealViewControllerSegue*) segue;
swSegue.performBlock = ^(SWRevealViewControllerSegue* rvc_segue, UIViewController* svc, UIViewController* dvc) {
UINavigationController* navController = (UINavigationController*)self.revealViewController.frontViewController;
[navController setViewControllers: @[dvc] animated: NO ];
[self.revealViewController setFrontViewPosition: FrontViewPositionLeft animated: YES];
};
}
}
但是从侧边栏菜单中选择项目时没有任何反应。可能是什么问题？感谢您的帮助。
