}
- (void)onDidBecomeActiveNotification:(NSNotification*)notification

通知测试用例

    -(void)setup{
        [super setUp];

    mClassObj = [[ClassA alloc]init];

    }

-(void)teaddown{

mClassObj = nil;
    [super tearDown];


}
 -(void)testUIApplicationDidFinishLaunchingNotification {

        [[NSNotificationCenter defaultCenter]postNotificationName:UIApplicationDidFinishLaunchingNotification object:nil];    
        }

期待这会奏效！

但是测试用例失败了

-[__NSCFString onDidFinishLaunchingNotification:]: unrecognized selector sent to instance

我正在尝试涵盖上述通知方法的测试用例，但它给了我错误，说无法识别的选择器已发送到实例！

任何人都建议我涵盖通知方法的测试用例

除了我认为setUp和tearDown（注意大写）的意外拼写错误之外，这段代码没有任何问题。我放了一个断点onDidFinishLaunchingNotification:，它被测试触发了。

问题是，一个常量 NSString 是如何潜入其中的？
