如何修复 componentsSeparatedByCharactersInSet 上的崩溃错误？

Question

我正在制作 IOS 与应用程序相关的地址簿。当我调用下面的函数获取带有“+”符号的 phone 数字时，有时会出现崩溃错误。有人知道这个错误吗？基本上我在 componentsSeparatedByCharactersInSet 函数上遇到错误。

- (NSString* ) clearedPhoneNumber:(NSString* ) dirty_number withPlus:(BOOL)plus {

    if (dirty_number == nil)
        return nil;

    NSString * in_string = plus?@"+0123456789":@"0123456789";

    NSString * phone_str = [[dirty_number componentsSeparatedByCharactersInSet:
                         [[NSCharacterSet characterSetWithCharactersInString:in_string]
                          invertedSet]] 
                        componentsJoinedByString:@""];

    // Get last 10 digits
    NSRange range = NSMakeRange(0, 0);
    if ([phone_str length] > MAX_PHONE_LENGTH) {
        range.location = 0;
        range.length = [phone_str length] - MAX_PHONE_LENGTH;
    }

   return [phone_str stringByReplacingCharactersInRange:range withString:@""];
}

这里还有崩溃报告。

这是调用 clearedPhoneNumber 函数的代码。

- (NSMutableArray *) Get_Phones_By_Person:(ABRecordRef)person localized:(BOOL)isLocalized {

ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);

if (phones == nil)
    return nil;

NSMutableArray * all_phones = [NSMutableArray array];

for(CFIndex j = 0; j < ABMultiValueGetCount(phones); j++) {
    CFStringRef phoneNumberRef = ABMultiValueCopyValueAtIndex(phones, j);
    NSString*  stripped_phone = [self clearedPhoneNumber:(__bridge NSString *)phoneNumberRef withPlus:YES];

    stripped_phone = [self getInternationalPhoneNumber:stripped_phone];
    if (stripped_phone != nil) {
        if (!isLocalized)
            [all_phones addObject:stripped_phone];
        else {
            CFStringRef locLabel = ABMultiValueCopyLabelAtIndex(phones, j);
            NSMutableDictionary * dict;
            if (locLabel != nil) {
                NSString* phoneLabel =(NSString*) CFBridgingRelease(ABAddressBookCopyLocalizedLabel(locLabel));
                dict = [NSMutableDictionary dictionaryWithObjectsAndKeys:(__bridge NSString *)phoneNumberRef, @"number", phoneLabel, @"name", nil];
                CFRelease(locLabel);
            }
            else {
                dict = [NSMutableDictionary dictionaryWithObjectsAndKeys:(__bridge NSString *)phoneNumberRef, @"number", nil];
            }

            [all_phones addObject:dict];
        }
    }

    CFRelease(phoneNumberRef);
}     

CFRelease(phones);

return all_phones;

}

我在两个模块中使用了地址簿。我已经从 linphone 模块中删除了地址簿。所以消失这个崩溃错误。请看下面link.
