應用程序崩潰與exc_bad_access代碼

Question

讓我來介紹我的應用程序的功能，我使用推送通知&地址簿和CoreTelephony框架。

我在我的應用程序中做的是，當我得到推送通知時，我將有效載荷中的數字保存在一個Appdelegate變量（Incoming_NO）中，如果沒有這樣的號碼聯繫，我會創建新的聯繫人並保存。 當我收到電話時，同樣的聯繫人姓名出現在我之前添加的，稍後我允許用戶編輯聯繫人，如果他想保存聯繫人或刪除，當他編輯聯繫人，並且以後當我收到與相同數量的我收到EXC_BAD_ACCESS到（Incoming_NO）我已經啓用了殭屍和我在同一個地方得到了斷點錯誤推送通知..

誰能幫我有什麼問題。

Received notification: { 
     aps =  { 
      alert = "Please help me-+918884718240"; 
      sound = "beep.caf"; 
     }; 
    } 

代碼：

NSString* alertValue = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"]; 

NSRange range=[alertValue rangeOfString:@":"]; 
    NSString *param,*msg; 
    NSRange range1=[alertValue rangeOfString:@":"]; 
    if (range1.location != NSNotFound) 
    { 
     param = [alertValue substringFromIndex:range1.location + range1.length]; 

     msg=[alertValue substringToIndex:range.location + range.length-1]; 
    } 
    else 
    { 
     range1=[alertValue rangeOfString:@"-"]; 
     if (range1.location != NSNotFound) 
     { 
      param = [alertValue substringFromIndex:range1.location + range1.length]; 

      msg=[alertValue substringToIndex:range1.location + range1.length-1]; 
     } 


    } 
if(range.length!=0) 
    { 
     parts= [NSMutableArray arrayWithArray:[alertValue componentsSeparatedByString:@":"]]; 

    }else 
    { 
     parts = [NSMutableArray arrayWithArray:[alertValue componentsSeparatedByString:@"-"]]; 
    } 

incoming_Number =[parts objectAtIndex:1];   

這個變量（incoming_Number）我得到的錯誤，當我保存聯繫人後收到推送通知。

我試圖改變incoming_Number類型爲NSString和NSMutableString，仍然是相同的錯誤，我猜是什麼發生是我指的是發佈的對象。但在調試器中，我可以看到它具有價值。

添加聯繫人代碼：

- (void)setContacts:(UIImage *) imgdata :(NSString *)incoming_number {

ABRecordRef loopingPerson=NULL; 
_Bool vizzical_present=false;

// ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(nil, nil); 

__block BOOL accessGranted = NO; 
if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6 
    dispatch_semaphore_t sema = dispatch_semaphore_create(0); 
    ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) { 
     accessGranted = granted; 
     dispatch_semaphore_signal(sema); 
    }); 
    dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER); 
    //dispatch_release(sema); 
} 
else { // we're on iOS 5 or older 
    accessGranted = YES; 
} 

if (accessGranted) { 
    //  int count = (int) ABAddressBookGetPersonCount(addressBook); 


    allContacts = (__bridge_transfer NSArray 
          *)ABAddressBookCopyArrayOfAllPeople(addressBook);

        } 

        CFRelease(newPerson); 
        CFRelease(addressBook); 

        CFRelease(phoneNumberMultiValue); 

      } 
     } 

    } 

} 
} 

在這裏，我做什麼，我檢查人是否存在與否，如果不是我檢查了默認聯繫人「VizziCal」如果當時我那不存在將新聯繫人創建爲「VizziCal」。

Answer 1

首先做所有這些東西獲取Incoming No，嘗試爲此自定義有效載荷。

很簡單。

看看Push Notification Programming Guide

你可以嘗試：

{ "alert": "Please help me", "phone": "9999999999" } 

注意：這將在服務器端創建。
