XCTAssertEqualObjects 和 NSManagedObjects

Question

我不确定为什么 XCTAssertEqualObjects 说这些对象不相等：

[PlayerService_Test testMapping] : ((player) equal to (mappingTest.destinationObject)) failed: ("<PlayerVO: 0x8ec13e0> (entity: PlayerVO; id: 0x8ec1440 <x-coredata:///PlayerVO/t4741C1FA-8A84-4A41-9F2E-9476B1900CFD2> ; data: {
    activities =     (
    );
    dob = "1986-08-15 23:00:00 +0000";
    firstName = Ahmed;
    fullName = nil;
    lastName = Ahmed;
    middleName = Ahmed;
    sex = m;
})") is not equal to ("<PlayerVO: 0x8f09660> (entity: PlayerVO; id: 0x8f57490 <x-coredata:///PlayerVO/t4741C1FA-8A84-4A41-9F2E-9476B1900CFD3> ; data: {
    activities =     (
    );
    dob = "1986-08-15 23:00:00 +0000";
    firstName = Ahmed;
    fullName = nil;
    lastName = Ahmed;
    middleName = Ahmed;
    sex = m;
})")

可能是因为activities 字段？是否有另一种方法可以在不迭代和比较其属性的情况下松散地比较两个对象？

所以这行得通，但它很讨厌：

XCTAssertEqualObjects([player valueForKey:@"firstName"], [mappingTest.destinationObject valueForKey:@"firstName"]);
XCTAssertEqualObjects([player valueForKey:@"middleName"], [mappingTest.destinationObject valueForKey:@"middleName"]);
XCTAssertEqualObjects([player valueForKey:@"lastName"], [mappingTest.destinationObject valueForKey:@"lastName"]);
XCTAssertEqualObjects([player valueForKey:@"dob"], [mappingTest.destinationObject valueForKey:@"dob"]);
XCTAssertEqualObjects([player valueForKey:@"sex"], [mappingTest.destinationObject valueForKey:@"sex"]);
