calling pushViewController from a inside a custom UITableViewCell class

Question

I have a custom UITableViewCell which is part of a navigation controller. The cell has a button and when that button is pressed I want to push a view onto my navigation controller.

I can do this pretty easily by using a selector in my cellForRowAtIndexPath method.

[cell.fooButton addTarget:self action:@selector(pushBarViewController:) forControlEvents:UIControlEventTouchUpInside];

And then inside of the pushBarViewController method I can perform the push operation

[self.navigationController pushViewController:barViewController animated:YES];

This works pretty well, but now I need to pass in some information contained in my custom UITableViewCell into my barViewController. My action:@selector will not allow me to pass in any arguments so I can't use this method.

I've created an action on the button press inside the custom UITableViewCell but I can't push the view from in here as there is no navigation controller.

Can anyone help?

Answer 1

How about this:

-(void)pushBarViewController{
    YourBarViewController *barViewController = [[YourBarViewController alloc] init];
    barViewController.myString = @"this string will be passed to the new view";
    [self.navigationController pushViewController:barViewController animated:YES];
    [barViewController release];
}

and in the header file YourBarViewController.h, define

NSString *myString;

with

@property(nonatomic, retain) NSString *myString;

and synthesize this in the implementation file.

Answer 2

Create some instance variables in the BarViewController class and set them before you push the controller.

Answer 3

Follow the example already given.

Answer 4

I managed to figure it out. I kept this:

[cell.fooButton addTarget:self action:@selector(pushBarViewController:) forControlEvents:UIControlEventTouchUpInside];

And then in the pushBarViewController I did this:

UIButton* button = (UIButton *)sender;
CustomCell *cell = (CustomCell *)[button superview];
NSUInteger row = [customTableView indexPathForCell:cell].row;
Foo *foo = [fooArray objectAtIndex:row];

Now that I have access to foo I can alloc my barViewController and set

barViewController.foo = foo

And then do the usual push.

[self.navigationController pushViewController:barViewController animated:YES];
