iPhone UIButton with UISwitch functionality - iphone

Question

Is there either a way to implement UISwitch with custom graphics for the switch-states?
Or as an alternative the other way round, an UIButton with UISwitch functionality?

Answer 1

UIButton already supports a "switch" functionality.
Just set a different image in Interface Builder for the "Selected State Configuration", and use the selected property of UIButton to toggle its state.

Answer 2

set the image to show on selected state:
[button setImage:[UIImage imageNamed:#"btn_graphics"] forState:UIControlStateSelected];
and then on touch up inside selector, set:
button.selected = YES;
if you want this to cancel another button's selection, set:
otherButton.selected = NO;

Answer 3

To build on what PGB and nurne said above, after you set your states and attach a selector (event method) you would want to put this code in that selector.
- (IBAction)cost:(id)sender
{
//Toggle current state and save
self.buttonTest.selected = !self.buttonTest.selected;
/**
The rest of your method goes here.
*/
}

Answer 4

For programmatically inclined:
-(void) addToggleButton {
CGRect aframe = CGRectMake(0,0,100,100);
UIImage *selectedImage = [UIImage imageNamed:#"selected"];
UIImage *unselectedImage = [UIImage imageNamed:#"unselected"];
self.toggleUIButton = [[UIButton alloc] initWithFrame:aframe];
[self.toggleUIButton setImage:unselectedImage forState:UIControlStateNormal];
[self.toggleUIButton setImage:selectedImage forState:UIControlStateSelected];
[self.toggleUIButton addTarget:self
action:#selector(clickToggle:)
forControlEvents:UIControlEventTouchUpInside];
[self addSubview:self.toggleUIButton];
}
-(void) clickToggle:(id) sender {
BOOL isSelected = [(UIButton *)sender isSelected];
[(UIButton *) sender setSelected:!isSelected];
}
