objective C语言 OCUnit在创建UITextView时崩溃

Question

单元测试目前正在处理一桶一桶的任务。我试图在我的banneradviewcontroller类上运行测试，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到达的方法:

-(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，则测试运行良好。(是的，如果你想知道，测试台与UIKit链接)。

哦，测试类是这样的

#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，并通过一些相关的线程跟踪，我(有点令人惊讶)设法解决了这个问题。问题源于这样一个事实，即在创建项目时没有设置测试目标。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连接起来。

我必须将以下两个标志添加到测试目标的构建设置中，测试现在运行良好:

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