programmatically created button click to open a tableview or popup - iphone

Question

I have created a button programmatically in a UITableViewCell and I want it to open a new table view or popup when clicked. Please give me some tutorial or hint. Below is my code:
UIButton *button =[UIButton buttonWithType:UIButtonTypeCustom];
button.frame=CGRectMake(0,0,360,25);
[button addTarget:self action:#selector(dropDownClick) forControlEvents:UIControlEventTouchUpInside];
-(IBAction)dropDownClick
{
//Here I know there should be some code but I am not getting what it should be since I am new to iPad/iPhone development
}

Answer 1

If you just want to show a popup when tapping the button, you can use UIAlertVIew
- (IBAction)dropDownClick {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Title of popup"
message:#"Did this popup show?"
delegate:self
cancelButtonTitle:#"Yes"
otherButtonTitles:nil];
[alert addButtonWithTitle:#"No"];
[alert show];
}

Here a sample to do it
//DISEGNO DELLE CELLE
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier;
CellIdentifier = #"CellStorico";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
CGRect tRect1 = CGRectMake(0.0f, 3.0f, 768.0f, 40.0f);
id title1 = [[UIButton alloc] initWithFrame:tRect3];
[title1 addTarget:self action:#selector(ClickCheck:) forControlEvents:UIControlEventTouchUpInside];
[title1 setTag:3];
[cell addSubview:title1];
[title1 release];
}
if ([[[Storico objectAtIndex:[indexPath row]] objectForKey:#"Selezionato"] isEqualToString:#"0"]) {
[(UIButton *) [cell viewWithTag:3] setImage:[UIImage imageNamed:#"NoCheck.png"] forState:UIControlStateNormal];
[(UIButton *) [cell viewWithTag:3] setImage:[UIImage imageNamed:#"NoCheck.png"] forState:UIControlStateHighlighted];
[(UIButton *) [cell viewWithTag:3] setImage:[UIImage imageNamed:#"NoCheck.png"] forState:UIControlStateSelected];
} else {
[(UIButton *) [cell viewWithTag:3] setImage:[UIImage imageNamed:#"Check.png"] forState:UIControlStateNormal];
[(UIButton *) [cell viewWithTag:3] setImage:[UIImage imageNamed:#"Check.png"] forState:UIControlStateHighlighted];
[(UIButton *) [cell viewWithTag:3] setImage:[UIImage imageNamed:#"Check.png"] forState:UIControlStateSelected];
}
return cell;
}
Click Management
-(void)ClickCheck:(id)sender{
//Ex. Load a New View
FrmScadenzeGenerali *SchermataScadenzeGenerali=[[FrmScadenzeGenerali alloc] initWithNibName:#"FrmScadenzeGenerali" bundle:nil];
[[self navigationController] pushViewController:SchermataScadenzeGenerali animated:YES];
[SchermataScadenzeGenerali release];
//Ex. PopUp a View
[self.view insertSubview:[TabTestata view] atIndex:0];
//Show a Message
UIAlertView *Alert = [[UIAlertView alloc] initWithTitle:#"Attenzione!" message:#"Error Text Message To Show!" delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[Alert show];
[Alert release];
}

I assume you are using a UINavigationController with your UITableView.
If so, you can do try this to make it open a new table view:
Make a new class which is a subclass of UITableViewController. Make sure the checkbox named "With XIB for user interface" is checked. Give it a name, i.e. "MyTableViewController".
Open the implementation file (the one ending in .m) of your class where you have your dropDownClick method, and import your new class with #import "MyTableViewController.h". Do this at the top of your class (.m file).
Edit your dropDownClick method to the following lines:
-(IBAction)dropDownClick
{
MyTableViewController *vc = [[MyTableViewController alloc] initWithNibName:#"MyTableViewController"]; // Loads a .xib file called "MyTableViewController.xib"
[self.navigationController pushViewController:vc animated:YES]; // This is where the swapping happens.
[vc release]; // Remember to do this if your app does not use ARC.
}
You could also do this without using a .xib, but then it would be a bit different.
