Terminating app due to uncaught exception 'NSInvalidArgumentException'
I have the following problem. I inherited an app and I am trying to modify it. The original functionality lets me add a task with some text notes. I want to add an icon to make it more visually appealing. When I modify the code signature to pass the icon (in reality I am only passing the name of the icon in a NSString) the modules stops working and the app throws the following error, basically an unrecognized selector:
2011-03-19 22:41:17.713 app[82653:207] -[RemindersDataManager addReminder:notes:locations:icon:]: unrecognized selector sent to instance 0xc700bc0

terminate called after throwing an instance of 'NSException'.
These are the original module's signature
AddReminderViewController.h

AddReminderViewController.m

if ([self dataVerification]) {
BOOL result = NO;
// try to add one geo fence or several geo fences

}
// successfully added - close
if (result) {
[self.navigationController popToRootViewControllerAnimated:YES];
}

}
#pragma mark -

// add geo fences to device location
NSArray *locations = [geoDataManager getAllRemindersLocations];
[deviceLocation addMonitoringLocations:locations];
// invoke delegate
[delegateMap didAddMonitoringLocations:locations];
}
- (BOOL)addReminder:(NSString *)title notes:(NSString *)notes
coordinate:(CLLocationCoordinate2D)coordinate address:(NSString *)address
{
if (![self checkReminderExistance:title]) {
return NO;
}
// all verifications are OK, adding reminder
[geoDataManager addReminder:title notes:notes coordinate:coordinate address:address];
[self updateDelegatesWithReminder:title notes:notes];
return YES;
}
- (BOOL)addReminder:(NSString *)title notes:(NSString *)notes location:(LocationEntity *)location {
return [self addReminder:title notes:notes locations:[NSArray arrayWithObject:location]];
}
- (BOOL)addReminder:(NSString *)title notes:(NSString *)notes locations:(NSArray *)locations {
if (![self checkReminderExistance:title]) {
return NO;
}
// all verifications are OK, adding reminder
[geoDataManager addReminder:title notes:notes locations:locations];
[self updateDelegatesWithReminder:title notes:notes];
return YES;
}
and the modified ones:
AddReminderViewController.m
- (IBAction)addReminder {
if ([self dataVerification]) {
BOOL result = NO;
// try to add one geo fence or several geo fences
if (self.address) {
result = [[GeoRemindersManager sharedInstance] addReminder:self.titleField.text notes:self.detailsField.text coordinate:self.coordinate address:self.address icon:(NSString *)iconButton.currentTitle];
}
else if (self.locations) {
result = [[GeoRemindersManager sharedInstance] addReminder:self.titleField.text notes:self.detailsField.text locations:self.locations icon:(NSString *)iconButton.currentTitle];
}
// successfully added - close
if (result) {
[self.navigationController popToRootViewControllerAnimated:YES];
}
}
}
GeoRemindersManager.h
// shared instance
+ (GeoRemindersManager *)sharedInstance;
// workflow
- (void)start;
- (BOOL)addReminder:(NSString *)title notes:(NSString *)notes
coordinate:(CLLocationCoordinate2D)coordinate address:(NSString *)address icon:(NSString *)icon;
- (BOOL)addReminder:(NSString *)title notes:(NSString *)notes location:(LocationEntity *)location icon:(NSString *)icon;
- (BOOL)addReminder:(NSString *)title notes:(NSString *)notes locations:(NSArray *)locations icon:(NSString *)icon;
- (void)changeReminder:(NSString *)title title:(NSString *)newTitle notes:(NSString *)newNotes icon:(NSString *)icon;
- (void)removeReminder:(NSString *)title;
- (ReminderEntity *)getReminderWithTitle:(NSString *)title;
- (NSArray *)getLoctionsWithCoordinate:(CLLocationCoordinate2D)coordinate;
- (void)wakeByLocalNotification:(NSDictionary *)info;
- (void)memoryWarning;
- (CLLocation *)getCurrentLocation;
// extra
- (BOOL)checkReminderExistance:(NSString *)title;
- (void)updateDelegatesWithReminder:(NSString *)title notes:(NSString *)notes icon:(NSString *)icon;
GeoRemindersManager.m
- (BOOL)addReminder:(NSString *)title notes:(NSString *)notes
coordinate:(CLLocationCoordinate2D)coordinate address:(NSString *)address icon:(NSString *)icon
{
if (![self checkReminderExistance:title]) {
return NO;
}
// all verifications are OK, adding reminder
[geoDataManager addReminder:title notes:notes coordinate:coordinate address:address icon:icon];
[self updateDelegatesWithReminder:title notes:notes icon:icon];
return YES;
}
- (BOOL)addReminder:(NSString *)title notes:(NSString *)notes location:(LocationEntity *)location icon:(NSString *)icon{
return [self addReminder:title notes:notes locations:[NSArray arrayWithObject:location icon:icon]];
}
- (BOOL)addReminder:(NSString *)title notes:(NSString *)notes locations:(NSArray *)locations icon:(NSString *)icon {
if (![self checkReminderExistance:title]) {
return NO;
}
// all verifications are OK, adding reminder
[geoDataManager addReminder:title notes:notes locations:locations icon:icon];
[self updateDelegatesWithReminder:title notes:notes];
return YES;
}
So in short, the only thing I added was an additional argument to those function for the icon name as a NSString… Any clues? All help greatly appreciated! Thanks

The error message indicates that the unrecognized selector was called on an object of class RemindersDataManager, probably from the line
[geoDataManager addReminder:title notes:notes locations:locations icon:icon];
You should find the implementation of that class and add your icon parameter to its methods too (or stop passing icon to it if it has no use for the icon).
