Question

我正在运行Xcode 6.1.1。我使用以下方法设置了新的测试目标：文件＆gt;新＆gt;目标

使用空模板运行测试工作正常。我导入了一个标题ServerController，并尝试创建一个实例：

#import <UIKit/UIKit.h>
#import <XCTest/XCTest.h>
#import "ServerController.h"

@interface Tixie_Tests : XCTestCase

@end

@implementation Tixie_Tests

- (void)setUp {
    [super setUp];
    // Put setup code here. This method is called before the invocation of each test method in the class.
    ServerController * s = [[ServerController alloc] init];
}

- (void)tearDown {
    // Put teardown code here. This method is called after the invocation of each test method in the class.
    [super tearDown];
}

- (void)testExample {
    // This is an example of a functional test case.
    XCTAssert(YES, @"Pass");
}

- (void)testPerformanceExample {
    // This is an example of a performance test case.
    [self measureBlock:^{
        // Put the code you want to measure the time of here.
    }];
}

@end

现在运行测试给了我这个：

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_ServerController", referenced from:
      objc-class-ref in <omitted>.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

对于在应用程序中查找类的链接器错误...在应用程序目标中将“默认隐藏的符号”构建设置设置为“NO”。这使您的所有应用程序类自动可用于您的测试目标... 所以，这意味着：

Project Navigator＆gt;选择你的项目

目标＆gt;选择您的应用程序（不是测试）

构建设置＆gt;搜索“默认隐藏的符号”

“默认隐藏的符号”＆gt;将其从“是”更改为“否”
