Prevent simultaneous click on Imageviews - ios

Question

I have 3 image views and I would like to prevent simultaneous taps on image views. how can I do that? Can anyone help me??
for (int i=0; i <= [_images1 count]-1; i++){
CGFloat xOrigin = i * self.view.frame.size.width/3;
wordsImage = [[UIImageView alloc] init];
[wordsImage setFrame:CGRectMake(xOrigin+20, self.view.frame.size.height/3,self.view.frame.size.width/3.5 , self.view.frame.size.height/5)];
[wordsImage setImage:[UIImage imageNamed: [_images1 objectAtIndex:i]]];
[self.view addSubview:wordsImage];
[wordsImage setTag:i];
wordsImage.userInteractionEnabled = YES;
tapGesture1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tapGesture:index_image:)];
tapGesture1.numberOfTapsRequired = 1;
[tapGesture1 setDelegate:self];
[wordsImage addGestureRecognizer:tapGesture1];
}

Answer 1

Use this method to restrict the sequence of click your same imageview. I hope this will help you.
int previousTag,curentTag,flag;
-(void)tapGesture:(id)sender{
UIGestureRecognizer *recognizer = (UIGestureRecognizer*)sender;
UIImageView *imageView = (UIImageView *)recognizer.view;
if(flag == 0){
previousTag = imageView.tag;
curentTag = 520; // unequal value you will enter here
flag = 1;
}
else {
curentTag = imageView.tag;
}
if(previousTag != curentTag)
{
[imageView setImage:[UIImage imageNamed:#"anyImage.png"]];
previousTag = curentTag;
}
}

If you want to prevents simultaneous click on Imageviews, you can set exclusiveTouch by YES.
/* exclusiveTouch
A Boolean value that indicates whether the receiver handles touch events exclusively.
Setting this property to YES causes the receiver to block the delivery of touch events to other views in the same window. The default value of this property is NO.
*/
for (int i=0; i <= [_images1 count]-1; i++){
CGFloat xOrigin = i * self.view.frame.size.width/3;
wordsImage = [[UIImageView alloc] init];
[wordsImage setFrame:CGRectMake(xOrigin+20, self.view.frame.size.height/3,self.view.frame.size.width/3.5 , self.view.frame.size.height/5)];
[wordsImage setImage:[UIImage imageNamed: [_images1 objectAtIndex:i]]];
[self.view addSubview:wordsImage];
[wordsImage setTag:i];
wordsImage.userInteractionEnabled = YES;
wordsImage.exclusiveTouch = YES;//Set this property
tapGesture1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tapGesture:index_image:)];
tapGesture1.numberOfTapsRequired = 1;
[tapGesture1 setDelegate:self];
[wordsImage addGestureRecognizer:tapGesture1];
}
I hope this would be helpful

W hen you tap the image view set one Bool variable to true and manage that variable.
