在Xcode 5.0.2(XCTest)中将新的测试目标添加到现有项目中虽然在编译测试目标时成功,但不起作用.

我已经在这里搜索但没有成功.

额外信息:
这是一个iOS应用程序部署目标是7.0它使用两个子项目(静态库)与资源包

这是错误消息:

2014-03-19 11:31:06.509 MyProject[53196:70b] Error loading /Users/rodrigoarantes/Library/Developer/Xcode/DerivedData/IgnitEdu-dcshcxphrysxcqdftuszmgdoweuz/Build/Products/Debug-iphonesimulator/MyProjectTests.xctest/MyProjectTests: dlopen(/Users/rodrigoarantes/Library/Developer/Xcode/DerivedData/IgnitEdu-dcshcxphrysxcqdftuszmgdoweuz/Build/Products/Debug-iphonesimulator/MyProjectTests.xctest/MyProjectTests, 262): no suitable image found.

我该如何解决这个错误？

任何帮助是极大的赞赏.

我有以下场景

@Entity
public class Parent {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Long id;

    @Column(name = "name", nullable = false)
    private String name;

    @OneToMany(fetch=FetchType.LAZY, cascade=CascadeType.ALL, mappedBy = "parent", orphanRemoval = true)
    private Set<Child> children;
   }
@Entity
public class Child {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Long id;

    @ManyToOne(fetch=FetchType.LAZY, optional = false)
    private Parent parent;
}

使用 JPA Criteria 或 JPQL 构建查询时，默认情况下我会在为子项请求连接获取时获得内部连接。

要么使用：

SELECT p from Parent p JOIN p.children

或者

EntityManager em = ...;
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<Parent> query = cb.createQuery(Parent.class);

Root<Parent> root = …

如何监听网络连接的变化？

你知道实现这个的任何实现或模块吗？

我想知道是否存在类似于:

  reachability.on('change' function(){...});
  reachability.on('connect' function(){...});
  reachability.on('disconnect' function(){...});

我用谷歌搜索了它,但却找不到任何关于它的信息.

任何帮助表示赞赏.谢谢
