iPhone Memory Error - when using Build & Debug, How to debug?
- by LonH99
I'm a newbie and need some help with an iPhone App running on the Simulator. The app works fine running with Build & Run or Build & Run - breakpoints off, but blows when running with Build & Debug - Breakpoints on. Any help or thoughts would be greatly appreciated. Lon
Specifics: No breakpoints set, never gets to any visible simulator results, seems to blow during initialization phase before it can generate any output. Source of app is the DrinkMixer example, in the "Head First iPhone development" book (example built up to page 280) by Dan & Tracey Pilone.
Blows With this Error Message:
Attaching to process 970.
Pending breakpoint 1 - "*0x01c1b001" resolved
Program received signal: “EXC_BAD_ACCESS”.
No memory available to program now: unsafe to call malloc
Data Formatters temporarily unavailable, will re-try after a 'continue'. (Not safe to call dlopen at this time.)

The code, including line #41 (noted below) is as follows. And thanks for the formatting help and comment:
import "RootViewController.h"
import "DrinkDetailViewController.h";
import "DrinkConstants.h"
import "AddDrinkViewController.h"
@implementation RootViewController
@synthesize drinks, addButtonItem;
- (void)viewDidLoad {
[super viewDidLoad];
// add PATH for PLIST
NSString *path = [[NSBundle mainBundle] pathForResource:
@"DrinkDirections" ofType:@"plist"];
NSMutableArray *tmpArray = [[NSMutableArray alloc] initWithContentsOfFile:path];
self.drinks = tmpArray;
[tmpArray release];
// Next is Line #41 - I removed earlier empty lines & Comments
self.navigationItem.rightBarButtonItem = self.addButtonItem;
}
- (IBAction) addButtonPressed: (id) sender {
NSLog(@"Add button pressed!");
