How to access or call an action in to a function - iphone

Question

I have the right navigation bar button action,I have set an action for it like the following:
-(IBAction)save:(id)sender
{
//Code for saving entered data
UITextField *fieldOne = [self.fields objectAtIndex:0];
UITextField *fieldTwo = [self.fields objectAtIndex:1];
UITextField *fieldThree = [self.fields objectAtIndex:2];
sqlite3_stmt *statement;
const char *dbpath = [databasePath UTF8String];
if (sqlite3_open(dbpath, &remindersDB) == SQLITE_OK && textField.text != nil)
{
NSString *insertSQL = [NSString stringWithFormat:#"INSERT INTO reminders(name, event, date) VALUES (\"%#\", \"%#\", \"%#\")", fieldOne.text, fieldTwo.text,fieldThree.text];
const char *insert_stmt = [insertSQL UTF8String];
sqlite3_prepare_v2(remindersDB, insert_stmt, -1, &statement, NULL);
NSLog(#"%#",fieldOne.text);
NSLog(#"%#",fieldTwo.text);
NSLog(#"%#",fieldThree.text);
if (sqlite3_step(statement) == SQLITE_DONE)
{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"\n Reminder Saved." message:nil delegate:nil cancelButtonTitle:nil otherButtonTitles:nil];
[alert show];
[alert dismissWithClickedButtonIndex:0 animated:YES];
[alert release];
}
else
{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Alert" message:#"Reminder not saved" delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
[alert release];
}
rowID = sqlite3_last_insert_rowid(remindersDB);
NSLog(#"last inserted rowId = %d",rowID);
sqlite3_finalize(statement);
sqlite3_close(remindersDB);
}
//Alert for not entering any data
if ([textField.text length] == 0)
{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Fill Data" message:#"Please fill name,event and date of reminder" delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[alert show];
[alert release];
}
++self.numberOfSaves;
NSLog(#"Number of saves = %d",numberOfSaves);
[self.tableView reloadData];
}
Now I want to check how many times the button is clicked,I have an idea in mind that to create a function and used the condition
-(int)numberOfSaves
{
int saves = 0;
if(self.navigationItem.rightBarButtonItem.enabled==YES)
{
saves++;
}
return saves;
}
It's not working......
Is there anyway to check such condition,If so how can I achieve it,I am newbie to objective-c,please help me out...
Thanks all in advance :)

You cannot return from a void method.
You'd want to change -(void)numberOfSaves to -(int)numberOfSaves, if that were the right way to go about things, but I don't think this is what you want.
In your header file (.h) you'll want to declare an instance variable for the class:
#property (nonatomic, strong) NSInteger numberOfSaves;
In your implementation file (.m) make sure to synthesize it:
#synthesize numberOfSaves = _numberOfSaves;
Replace your IBAction method:
- (IBAction)save:(id)sender
{
++self.numberOfSaves;
}
And just throw away the -(void)numberOfSaves method all together. This should accomplish what I think you're trying to do. You can figure out how many saves you have committed now with self.numberOfSaves
