you can use these 2 methods,

-(void) incrementonebadge{     nsinteger numberofbadges = [uiapplication sharedapplication].applicationiconbadgenumber;     numberofbadges +=1;      [[uiapplication sharedapplication] setapplicationiconbadgenumber:numberofbadges]; }  -(void) decrementonebdge{     nsinteger numberofbadges = [uiapplication sharedapplication].applicationiconbadgenumber;     numberofbadges -=1;      [[uiapplication sharedapplication] setapplicationiconbadgenumber:numberofbadges]; }
