I am trying to create a toggle button for each cell in my table. When pressed, it will change the image and when pressed again it will change the image again -- Toggle.
In the UIButton
class I don't see a selected
state.
I'm looking for a way to create a toggle button with UIButton so that I can change the state on each click.
This is how I'm doing it in rubymotion
right now using rmq
@fav_button.on(:touch) do |sender|
puts "pressed fav button for id: " + data[:id] + " and name: " + data[:name]
#how do I change the state here?
end
You can create toggle button easily, you just need to set respective images for respective states, after that, you can use the selected
property to toggle between these images.
I made a pure objective-c code to show how you can do that, but you can set the images anyway in Storyboards ou Xibs too, check out:
// First, set the images for normal state and selected state
[button setImage:normalImage forState:UIControlStateNormal];
[button setImage:selectedImage forState:UIControlStateSelected];
// Don't forget to add an action handler to toggle the selected property
[button addTarget:self action:@selector(buttonTouch:withEvent:) forControlEvents:UIControlEventTouchUpInside];
// Now, in your button action handler, you can do something like this:
- (void)buttonTouch:(UIButton *)aButton withEvent:(UIEvent *)event
{
aButton.selected = !aButton.selected;
}
I hope this can help you.
