數學應用程序崩潰

Question

我正在製作一個簡單的數學應用程序，Xcode表示它的構建正確，但該應用程序無法在模擬器或我的設備上打開。這是一個基於winow的應用程序，但是我手動添加了一個UITabBarController。

這是我AreaViewController.h說什麼

#import <UIKit/UIKit.h> 


@interface AreaViewController : UIViewController { 
    <snipped ivars> 
} 

@property (retain, nonatomic) UITextField *add11; 
@property (retain, nonatomic) UITextField *add12; 
@property (retain, nonatomic) UITextField *add13; 
@property (retain, nonatomic) UITextField *add21; 
@property (retain, nonatomic) UITextField *add22; 
@property (retain, nonatomic) UITextField *add23; 
@property (retain, nonatomic) UITextField *add31; 
@property (retain, nonatomic) UITextField *add32; 
@property (retain, nonatomic) UITextField *add33; 
@property (retain, nonatomic) UILabel *add1Result; 
@property (retain, nonatomic) UILabel *add2Result; 
@property (retain, nonatomic) UILabel *add3Result; 

-(IBAction)calculate:(id)sender; 
-(IBAction)hideKeyboard:(id)sender; 

@end 

我AreaViewController.m

#import "AreaViewController.h" 


@implementation AreaViewController 

@synthesize add11, add12, add13; 
@synthesize add21, add22, add23; 
@synthesize add31, add32, add33; 
@synthesize add1Result, add2Result, add3Result; 

-(IBAction)calculate:(id)sender { 
float floatAdd1Result=[add11.text floatValue]+[add12.text floatValue]+[add13.text floatValue]; 
float floatAdd2Result=[add21.text floatValue]+[add22.text floatValue]+[add23.text floatValue]; 
float floatAdd3Result=[add31.text floatValue]+[add32.text floatValue]+[add33.text floatValue]; 

add1Result.text=[NSString stringWithFormat:@"%1.2f",floatAdd1Result]; 
add2Result.text=[NSString stringWithFormat:@"%1.2f",floatAdd2Result]; 
add3Result.text=[NSString stringWithFormat:@"%1.2f",floatAdd3Result]; 
} 

-(IBAction)hideKeyboard:(id)sender { 
[add11 resignFirstResponder]; 
[add12 resignFirstResponder]; 
[add13 resignFirstResponder]; 
[add21 resignFirstResponder]; 
[add22 resignFirstResponder]; 
[add23 resignFirstResponder]; 
[add31 resignFirstResponder]; 
[add32 resignFirstResponder]; 
[add33 resignFirstResponder]; 
}  

- (void)dealloc { 
[add11 release]; 
[add12 release]; 
[add13 release]; 
[add21 release]; 
[add22 release]; 
[add23 release]; 
[add31 release]; 
[add32 release]; 
[add33 release]; 
[add1Result release]; 
[add2Result release]; 
[add2Result release]; 
[super dealloc]; 
} 


@end

編輯戴維DELO ng：

我儘可能地減少了代碼。我刪除了實例變量聲明，並且留下了@property聲明，摺疊了@synthesize行，簡化了代碼，剝離了死亡方法，剪掉了長時間重複的東西等。我還刪除了代碼下載鏈接，因爲它只鏈接到壓縮的副本.xcodeproj文件（但沒有源文件）。

Answer 1

事實上，你在動態加載器中死去似乎意味着你的二進制文件沒有正確構建。當我開始發生奇怪的錯誤時，我發現最好清理整個項目並重新構建一切。要清理，只需轉到Build菜單並選擇「清理所有目標」。一旦完成，請嘗試再次建立並運行。

Answer 2

有時，這有助於我：

1. 重新啓動設備
2. 重新啓動的Xcode
3. 乾淨所有的構建和乾淨的Xcode緩存
4. 刪除所有斷點......我看到的Xcode變得瘋狂，從項目中刪除所有斷點後再次正常。有時Xcode會丟失彈珠，你必須幫助它。
5. 作爲一個激進的措施右鍵單擊xcodeproj文件，選擇Show Package Contents並刪除該包內除pbxproj文件外的所有內容。然後重新打開該項目。

做＃5讓你的項目的備份...以防萬一之前。

編輯：

你可以有你的磁盤或Xcode的一個問題。使用磁盤實用程序並驗證/修復磁盤上的權限，刪除然後重新安裝新版本的Xcode/SDk。看看是否有效。

Answer 3

嘗試：

1. 拔掉電話
2. 從手機中刪除應用程序（使用的牽着你的手指放在圖標上，直到「X」的標準方法出現）
3. 一旦刪除，插頭回到並重新打造
4. 再次在設備上的應用程序崩潰，但大跌後這段時間，再次拔出並直接從手機
