Recognize click or gesture event on disabled UIButton - ios

Question

My button is disabled but I want to show a message box when user clicks on it. How can I do it? Also I would like to mention that UIbutton is added on UITableview, and I tried the code below, but it always goes to else in DisableClick() function.
In cellForRowAtIndexPath:
button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:CGRectMake(180, 6, 30, 30)];
[button setTag:4000];
[button addTarget:self action:#selector(click:event:) forControlEvents:UIControlEventTouchDown];
UITapGestureRecognizer* gesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(DisableClick:)];
[self.view addGestureRecognizer:gesture];
[gesture release];
[cell.contentView addSubview:button];
In DisableClick()
- (void)DisableClick:(UIButton*)sender {
UITapGestureRecognizer *recognizer = (UITapGestureRecognizer *)sender;
CGPoint pt = [recognizer locationOfTouch:0 inView:market];
if (CGRectContainsPoint(market.bounds, pt)) {
NSLog(#"Disabled button tapped");
}
else
{
NSLog(#"go out"); // it's always go to here
}
}

Answer 1

Rather than desabling the button keep it enable. Change the image of button like disable image. Put a flag variable when button is tapped use this flag variable to run the code of enabled button and disabled button
BOOL btnFlg;//initialize it true or false on cellForRowAtIndex... method
- (void)DisableClick:(UIButton*)sender
{
if(btnFlg)
{
btnFlag=NO;
NSLog("button disabled");
}
else
{
btnFlag=YES;
NSLog("button enabled");
}
}

Why you are initialize a tap gesure for this button. You set the selector in ur addTarget
Maintain a btn boolean for the button status . Change the status whenever you want to disable or enable.
BOOL btnEnabled;
button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:CGRectMake(180, 6, 30, 30)];
[button setTag:4000];
[button addTarget:self action:#selector(DisableClick:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:button];
Make the target function as
- (void)DisableClick:(UIButton*)sender {
//set the function that you needed when the user tap on this button here.
if(btnEnabled) {
// here invoke the functions you needed when the button enabled
} else {
UIAlertView *msg = [[UIAlertView alloc]initWithTitle:#"Alert" message:#"Your button is disabled" delegate:self cancelButtonTitle:#"OK" otherButtonTitles: nil];
[msg show];
}
}

You will need to subclass UIButton and implement
touchesBegan:withEvent: and touchesEnded:withEvent: methods for your purpose.
