代码：

    propValue = newValues[@“AAA”];
    if (propValue && propValue != self.isAAA) {
      [self setValue:propValue forKey:@"isAAA”];
    }

    propValue = newValues[@“BBB”];
    if (propValue && propValue != self.isBBB) {
      [self setValue:propValue forKey:@"isBBB”];
    }

//LIne 444
    propValue = newValues[@“CCC”];
    if (propValue && (self.CCC== nil || [[NSNumber numberWithUnsignedLongLong: strtoull([propValue UTF8String], nil, 10)] isEqualToNumber:self.CCC] == NO)) {
      self.CCC= [NSNumber numberWithUnsignedLongLong: strtoull([propValue UTF8String], nil, 10)];
    }

    propValue = newValues[@“DDD”];
    NSAssert(propValue == nil || propValue == [NSNull null] || [propValue isKindOfClass:[NSString class]], @"propValue is of wrong type");
    if (propValue && ![propValue isEqualToString:self.DDD]) {
      self.DDD = propValue;
    }

发生崩溃时输入数据。注意输入数据中缺少键DDD（第444行）。

{ A1 = 1143749791; A2 = Available; A3 = "Yudi Hartanto \U5ed6 \U53ef \U767c"; A4 = DEFRSVX; A5 = 0; A6 = 1; AAA = 0; BBB = 0; A7 = 192; A8 = ""; A9 = 1522125793; pins = ( 55a86fc1 ); A10 = 100011430136; A11 = 0; A12 = 0; A13 = Default; A14 = "pim://user/id/1"; A15 = equator; }

对我来说，这种崩溃似乎不是由于缺少键或意外的对象键造成的，因为它的SIGSEGV以及每个语句都受到保护。 Google搜索将其映射到任何其他对称问题，但没有运气。崩溃的可能原因是什么？

在NSDIctionary中设置值时，SIGSEGV CRASH
