POWhere do I create global variables for an iOS app?
text
Body
copied!<p>Here is my code:</p> <p>I want to be able to create a global NSMutableArray that can store Budget* objects that can then be written to a .pList file... I'm only learning what pLists are, and I am a bit hazy about how to implement them...</p> <p>Where am I going wrong here?</p> <pre><code>- (IBAction)btnCreateBudget:(id)sender { Budget *budget = [[Budget alloc] init]; budget.name = self.txtFldBudgetName.text; budget.amount = [self.txtFldBudgetAmount.text intValue]; // Write the data to the pList NSMutableArray *anArray = [[NSMutableArray alloc] init]; // I want this to be a global variable for the entire app. Where do I put this? [anArray addObject:budget]; [anArray writeToFile:[self dataFilePath] atomically:YES]; /* As you can see, below is where I test the code. Unfortunately, every time I run this, I get only 1 element in the array. I'm assuming that this is because everytime the button is pressed, I create a brand new NSMutableArray *anArray. I want that to be global for the entire app. */ int i = 0; for (Budget * b in anArray) { i++; } NSLog(@"There are %d items in anArray",i); } -(NSString *) dataFilePath { NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentDirectory = [path objectAtIndex:0]; return [documentDirectory stringByAppendingPathComponent:@"BudgetData.plist"]; } </code></pre> <p>edit: I'd like to add that I am creating the anArray array so that it can be accessible by other views. I understand that this can be done with NSNotification? or Should I do this the appDelegate classes? The end goal is to have the anArray object populate a UITableView that is in a separate View.</p>
