disabling multitouch not working ios - ios

Question

I have a view controller(VC) having 3 buttons(country , state , city). On click of these buttons , i am presenting another VC(using popover segue) , which is a search table to search country (or states or city). Now if user clicks two buttons , then both the view controller are presented at the same time. I want only one to be presented.How to do this?
Tried self.view.multipleTouchEnabled = NO; but not working.
code of the searchVC:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
UIImage *bgApplication = [UIImage imageNamed:#"bg-app-568h.jpg"];
self.view.backgroundColor = [UIColor colorWithPatternImage:bgApplication];
self.searchItems = [self loadData];
self.filteredSearchItems = [NSMutableArray arrayWithCapacity:[self.searchItems count]];
for (UIView *view in self.SearchBarBase.subviews){
if ([view isKindOfClass: [UITextField class]]) {
UITextField *tf = (UITextField *)view;
tf.delegate = self;
break;
}
}
}
- (NSArray *)loadData
{
MatchDayDataController * sharedController = [MatchDayDataController sharedDataController];
NSArray *data = [sharedController fetchStates];
//NSLog(#"states: %#", data);
return data;
}
Code of the presenter VC:
-(void) viewWillAppear:(BOOL)animated
{
keyboardIsShown = NO;
MatchDayDataController *sharedController = [MatchDayDataController sharedDataController];
// Load match venue data
self.locationField.text = sharedController.matchVenue;
//Load home team related data
NSString *stateText = [sharedController.homeStateName stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
if ([stateText length] == 0 )
{
self.selectHomeAssoc.enabled = NO;
self.selectHomeClub.enabled = NO;
}
NSString *homeAssocText = [sharedController.homeAssociationName stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
if ([homeAssocText length] == 0 )
{
self.selectHomeAssoc.enabled = YES;
self.selectHomeClub.enabled = NO;
}
NSString *homeClubText = [self.homeClub.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
if ([homeClubText length] == 0 )
{
self.selectHomeClub.enabled = YES;
}
self.stateTextFieldHome.text = sharedController.homeStateName;
self.homeAssociation.text = sharedController.homeAssociationName;
self.homeClub.text = sharedController.homeClubName;;
self.homeTeam.text = sharedController.homeTeamName;

self.stateTextFieldAway.text = sharedController.awayStateName;
self.awayAssociation.text = sharedController.awayAssocationName;
self.awayClub.text = sharedController.awayClubName;
self.awayTeam.text = sharedController.awayTeamName;

dateTimeString = [dateTimeString stringByAppendingString:self.timeField.text];
//NSLog(#"DateTimeString : %#", dateTimeString);
NSDate *matchDateTime = [dateFormatter dateFromString:dateTimeString];
sharedController.inspectionDate = matchDateTime;
//Save Home team related data
sharedController.homeTeamName = self.homeTeam.text;
// Save away team related data
sharedController.awayTeamName = self.awayTeam.text;
[sharedController saveData];
// hide the keyboard when we come back after leaving the cursor on text field.
// I have called resignFirstResponder on homeTeam Text field. You can use any of text field to hide.
[self.homeTeam resignFirstResponder];
[self.awayTeam resignFirstResponder];

Any ideas ?
Thanks,

Answer 1

You can create static bool variable busy, and at first line of each button action method check out state of this variable. If busy equal to NO, then set her to YES and at last line of action method or somewhere else set her to NO. If busy equal to YES do return from action method. So, until first called method didn't finish no other methods will be running.
#implementation yourController
-(void)changeCountry
{
if (!busy)
{
busy = YES;
// do what you need
} else return;
}
-(void)changeState
{
if (!busy)
{
busy = YES;
// do what you need
} else return;
}
#end
You should implement singleton, which return a static instance with BOOL value for using him in difference viewControllers (1 mainC + 3 popOverC) and set busy to NO when you finish edition.

try self.view.exclusiveTouch = YES;
