I created a UISwitch using this code...

UISwitch *switch = [[UISwitch alloc]initWithFrame:CGRectMake(110, 230, 60, 60)];
[window addSubview:switchView];
[switchView release];

The created button will be....

enter image description here

The default properties are,

  1. It contains "ON" & "OFF" states
  2. The OFF button is white & the ON button is in blue color

I want to create a customized switch, so that the background color & text in the switch should be changed. Is it possible? Please explain in detail.

Thanks in Advance,

Rajkanth

You can not modify UISwitch control unless and until you write your own control,

But best way so far, you can used UISegmentControl and handle event on it to switch the on.png and off.png images.

UISegmentedControl* switchView=[[UISegmentedControl alloc] initWithItems:[[[NSMutableArray alloc] initWithObjects:@"On",@"Off",nil] autorelease]];
    [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];

    self.navigationItem.titleView=switchView;

and write checkOnOffState method code like this-

-(IBAction)checkOnOffState:(id)sender{

    UISegmentedControl* tempSeg=(UISegmentedControl *)sender;
    if(tempSeg.selectedSegmentIndex==0){
        [tempSeg setImage:[UIImage imageNamed:@"onSelected.png"] forSegmentAtIndex:0];
        [tempSeg setImage:[UIImage imageNamed:@"off.png"] forSegmentAtIndex:1];
    }
    else{
        [tempSeg setImage:[UIImage imageNamed:@"on.png"] forSegmentAtIndex:0];
        [tempSeg setImage:[UIImage imageNamed:@"offSelected.png"] forSegmentAtIndex:1];
    }   
}
