我想在我的 iPhone 应用程序中执行 IBAction 后向特定的 ViewController 显示(或关闭) View 。我试过了
[self.parentViewController.parentViewController dismissModalViewControllerAnimated:YES];
然而，一旦执行了操作，这似乎没有任何作用。
更多信息:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];
if (selectedCell.tag == 1)
{
UIActionSheet *actionSheet = [[UIActionSheet alloc]
initWithTitle:@"Are you sure you want to delete this project?"
delegate:self cancelButtonTitle:@"No" destructiveButtonTitle:@"Yes, I’m Sure" otherButtonTitles:nil];
[actionSheet showInView:self.view];
}
}
- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex
{
if (buttonIndex != [actionSheet cancelButtonIndex])
{
[self.tableView beginUpdates]; // Avoid NSInternalInconsistencyException
// Delete the project object that was swiped
Project *projectToDelete = self.project;
NSLog(@"Deleting (%@)", projectToDelete.name);
[self.managedObjectContext deleteObject:projectToDelete];
[self.managedObjectContext save:nil];
}
}
我希望当前 View 在用户按下操作表上的"is"按钮时消失。
最佳答案
// Assume we are inside a UIViewController (or a subclass)
DestinationController *destinationController = [[DestinationController alloc] init];
[self presentModalViewController:destinationController animated:YES];
...
// Assume we are now in destination controller
// Dismiss
[self dismissModalViewControllerAnimated:YES];
