Question

I am using the following code to create a custom switch:

UISegmentedControl* switchView=[[UISegmentedControl alloc] 
                                initWithItems:[[NSMutableArray alloc] initWithObjects:@"On",@"Off",nil]];
[switchView setFrame:CGRectMake(20,365,140,28)];
switchView.selectedSegmentIndex=0;
switchView.segmentedControlStyle=UISegmentedControlStyleBar;
[switchView setImage:[UIImage imageNamed:@"onSelected.png"] forSegmentAtIndex:0];
[switchView setImage:[UIImage imageNamed:@"off.png"] forSegmentAtIndex:1];
[switchView addTarget:self action:@selector(checkOnOffState:) forControlEvents:UIControlEventValueChanged];

I would now like to add this control to one of my screens (I believe the correct term is ViewController?). How would I do this in Xcode 4.3?

I looked at a few other posts and was not able to find anything that works. For example, How do I add a custom view to iPhone app's UI? suggested something along the lines of
[[myVC view] addSubview:myView];
and How to customize UISwitch button in iphone? suggested
self.navigationItem.titleView=switchView;
If possible, could you also explain why these approaches did not work? Thanks.

Answer 1

You need to create a class for your switch which is subclass of your UISegmentControl ,
Else you can add this code in your vc directly as well.

Add this code in its initWithFrame method

and then use it in your VC

-(void)viewDidLoad{
  urCustomSwitch  = [urCustomSwitch alloc] initWithFrame:CGRectMake(20,365,140,28)];
  [self.view addSubview:urCustomSwitch];
}

This shall serve your purpose if you are to create custom reusable class.
