iPhone 메모리 오류 - 빌드 및 디버그를 사용할 때 디버그하는 방법?

Question

저는 초보자이며 시뮬레이터에서 실행되는 iPhone 응용 프로그램에 대한 도움이 필요합니다. 응용 프로그램은 잘 작동합니다. 빌드 & 실행 또는 빌드 & 실행 중단 점은 꺼져 있지만 빌드 & 디버그 - 중단 점 켜짐으로 실행하면 불면합니다. 어떤 도움이나 생각이라도 대단히 감사하겠습니다. Lon

세부 사항 : 중단 점 설정 안 함, 보이는 시뮬레이터 결과에 도달하지 않음, 출력을 생성하기 전에 초기화 단계에서 불어 오는 것처럼 보임. 앱 출처는 Danoney & Tracey Pilone의 "Head First iPhone 개발"책 (280 페이지에 작성된 예제)의 DrinkMixer 예제입니다. 이 에러 메시지

불면 다음과 같이

Attaching to process 970.

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.)

Object Allocations shows (Highest at top = CFString):

(아래에서 언급) 라인 # 41를 포함하는 코드이다. 그리고 형식의 도움과 의견에 대한 감사 :

#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!");

당신은 악기와 NSZombie 감지를 사용하여 시도 적이 : http://www.markj.net/iphone-memory-debug-nszombie/
