iPhone內存錯誤 - 使用Build＆Debug時，如何調試？

Question

我是一個新手，需要在模擬器上運行的iPhone應用程序的一些幫助。使用Build & Run或Build &運行 - 斷點關閉，但在使用Build &運行時出現調試 - 斷點處於打開狀態。任何幫助或想法將不勝感激。 Lon

細節：沒有設置斷點，永遠不會看到任何可見的模擬器結果，在初始化階段似乎會產生任何輸出。應用程序的源代碼是DrinkMixer的例子，由Dan & Tracey Pilone撰寫的「Head First iPhone development」一書（示例建立在第280頁）。

吹燈與此錯誤消息：

Attaching to process 970.

Object Allocations shows (Highest at top = CFString):

的代碼，其中包括線路＃41（下面說明）如下。而感謝格式幫助和評論：

#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!");
