iOS disable programatically created buttons until function completion - ios

Question

Hi and thanks in advance for you patience and help :)
Here is what I am doing:
- I create programmatically multiple buttons that call the same function
And what I want to accomplish:
- after a button is pressed, I want the common function to run and all the buttons to be disabled so that the function won't be called again during execution of the firs call. after the first call is ended I want to reenable the buttons.
Here is how I create the buttons:
#interface ViewController ()
{
UIButton *button;
}
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
int tagForTheButton = 0;
int yPossition = 0;
int xPossition = 0;
for (int numberOfTheColomn = 0; numberOfTheColomn < 6; numberOfTheColomn++) {
button = [UIButton buttonWithType:UIButtonTypeCustom];
button.adjustsImageWhenHighlighted = NO;
button.frame = CGRectMake(xPossition, yPossition, 64, 64);
button.tag = tagForTheButton;
[button setTitle:title forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
[self.scroll addSubview:button];
yPossition=yPossition+100;
tagForTheButton++;
}
}
-(void)buttonPressed:(id)sender{
//This is my attempt to disable the buttons
//previous mistake used 2578
for (int numberForIncrease; numberForIncrease<6; numberForIncrease++) {
if (button.tag == numberForIncrease) {
UIButton *btn = (UIButton*)[self.scroll viewWithTag:numberForIncrease];
btn.enabled=NO;
[btn setUserInteractionEnabled:NO];
}
}
}

Answer 1

You must be disabling it incorrectly. The docs for UIButton.enabled state:
If the enabled state is NO, the control ignores touch events and
subclasses may draw differently.
Check that DisableButton is being called by adding an NSLog() call, & do away with the DisableButton method altogether:
dispatch_sync(dispatch_get_main_queue(), ^{
self.view.userInteractionEnabled = NO;
_btn_sync_outlet.enabled = NO;
_btn_sync_outlet.userInteractionEnabled = NO;
});
This might helps you :)

I don't understand why you need to loop from 0 to 2577 for disabling a button which you already have an iVar pointing to..?
why don't you just switch off userInteraction to your entire view (or if that is not possible to a containerView which holds all the buttons)?
[self.view setUserInteractionEnabled: NO ];
or, failing that why not just haver an iVar there?
{
BOOL _ignoreButtons;
}
-(void)buttonPressed:(id)sender{
if (!_ignoreButtons){
_ignoreButtons = YES;
//do your time consuming job, possibly on bg thread
//on completion..
_ignoreButtons = NO;
}
}
