restore UIImageView Image in IBAction - ios

Question

I am adding an image in IBAction, I want to restore the old image back once the button is tapped.
It is not the image in the UIButton, it's the image in the UIImageView
- (IBAction)findMe:(id)sender
{
[self.imageView setImage:[UIImage imageNamed:#"image2"]];
}
I want to restore#"image1". immediate once button is tapped
some thing i need is some thing similar to
button setImage:[UIImage imageNamed:#"clicked.png"] forState:UIControlStateSelected | UIControlStateHighlighted];
but i don't want to change Button Image, but change UIImageView Image when clicked

Answer 1

You can use the following code
[yourButton addTarget:self action:#selector(touch2:) forControlEvents:UIControlEventTouchDown];
[yourButton addTarget:self action:#selector(touch3:) forControlEvents:UIControlEventTouchUpInside];
Now the selectors
-(void)touch2:(UIButton *)send
{
imageView.image= [UIImage imageNamed:#"image1"];
}
-(void)touch3:(UIButton *)send
{
imageView.image= [UIImage imageNamed:#"image2"];
}

Answer 2

Try it out:
- (IBAction)findMe:(id)sender
{
if (self.imageView.image) {
// store your old image here
NSLog(#"%#", self.imageView.image)
}
[self.imageView setImage:[UIImage imageNamed:#"image2"]];
}

Try this first create gesture for UIButton
UILongPressGestureRecognizer *btn_LongPress_gesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:#selector(handleBtnLongPressgesture:)];
[buttonFindMe addGestureRecognizer:btn_LongPress_gesture];
When you press and release the button it calls this method.
-(void)handleBtnLongPressgesture:(UILongPressGestureRecognizer *)recognizer{
//as you hold the button this would fire
if (recognizer.state == UIGestureRecognizerStateBegan) {
//Change your image 1
}
//as you release the button this would fire
if (recognizer.state == UIGestureRecognizerStateEnded) {
//Change your image 2
}
}
