创建UITextView时OCUnit崩溃

Question

目前，单元测试正在处理大量的问题。我试图在我的BannerAdViewController-class上运行测试，但当到达以下行时，一切都崩溃了：

UITextView *buyAppTextView  = [[UITextView alloc] initWithFrame:CGRectMake(8, 2, 304, 50)];

控制台输出如下：

-[__NSCFType markupDescription]: unrecognized selector sent to instance 0x1bc2de0

这是它在崩溃发生之前达到的方法：

-(void)setup{   
    _bannerFrame    = [self frameRectForBannerAd];
    _bannerWrapperFrame = [self frameRectForBannerWrapperFrame];

    UITextView *buyAppTextView  = [[UITextView alloc] initWithFrame:CGRectMake(8, 2, 304, 50)];
    [buyAppTextView setText:@"some text"];
    [buyAppTextView setTextColor:[UIColor blackColor]];
    [buyAppTextView setFont:[UIFont systemFontOfSize:10]];
    [buyAppTextView setAutoresizingMask:UIViewContentModeScaleAspectFit];
    [buyAppTextView setUserInteractionEnabled:NO];  

    _placeHolderBanner  = [[UIView alloc] initWithFrame:_bannerFrame];

    [_placeHolderBanner setBackgroundColor:[UIColor whiteColor]];
    [[_placeHolderBanner layer]  setBorderColor:[UIColor blackColor].CGColor];
    [[_placeHolderBanner layer] setBorderWidth:1.0];
    [_placeHolderBanner addSubview: buyAppTextView];

    [[self view] setFrame:_bannerWrapperFrame];
    [[self view] setBackgroundColor:[UIColor clearColor]];
    [[self view] addSubview: _placeHolderBanner];

    _iAdBanner  = [[ADBannerView alloc] initWithFrame:CGRectZero];

    [[self view] addSubview: _iAdBanner];
    _iAdBanner.delegate = self;
    _iAdBanner.hidden = YES;
}

如果我注释掉与buyAppTextView有关的所有内容，测试运行得很好。(是的，如果您想知道的话，测试设备与UIKit链接在一起)。

哦，测试类看起来像这样

#import "NorBannerAdViewTests.h"
#import "NORBannerAdViewController.h"

@implementation NorBannerAdViewTests

NORBannerAdViewController *_adViewController;

- (void)setUp{
    [super setUp];
    _adViewController = [[NORBannerAdViewController alloc] init];
}

- (void)tearDown{
    [super tearDown];
    [_adViewController release];
}

-(void) testThatFrameRectForBannerAdWrapperDoesNotReturnZero{
    CGRect receivedFrame = [_adViewController frameRectForBannerWrapperFrame];
    STAssertFalse((CGRectIsEmpty(receivedFrame)), @"receivedFrame should not be zero");
}

-(void) testThatFrameRectForBannerAdDoesNotReturnZero{
    CGRect receivedFrame = [_adViewController frameRectForBannerAd];    
    STAssertFalse((CGRectIsEmpty(receivedFrame)), @"receivedFrame should not be zero");
}

@end

经过广泛的谷歌搜索，并追踪了一些相关的帖子，我(有点令人惊讶)设法解决了这个问题。问题源于在创建项目时没有设置Test目标。因为它是基于一个Cocos2D模板，所以我必须自己添加它。这样做，我没有将测试目标的构建设置与应用程序挂钩。

我必须将以下两个标志添加到测试目标的构建设置中，现在测试运行良好：

Bundle Loader: $(BUILT_PRODUCTS_DIR)/AppName.app/AppName
Test Host: $(BUNDLE_LOADER)
