我已经按照步骤在xcode中添加自定义字体,每天都是swift和 自定义字体,但是我无法以编程方式在app标签中设置该字体.

var labeladd = UILabel(frame: CGRectMake(40, 50, 70, 22))
    //  label.center = CGPointMake(160, 284)
 ///  labeladd.font=UIFont.boldSystemFontOfSize(15)
   labeladd.font = UIFont(name:"Source Sans Pro",size:15)
    labeladd.textColor=UIColor.blackColor()
    labeladd.textAlignment = NSTextAlignment.Center
    labeladd.text = "this is custom fonts"
    myview.addSubview(labeladd)

在尝试为测试目的生成IPA时,我收到一条消息:

"您在会员中心拥有有效的iOS分发证书,但未在本地安装.如果您的签名身份安装在另一台Mac上,您可以在该Mac上导出开发人员个人资料并将其导入此Mac.您可以撤销当前证书和请求一个新的."

为什么会这样？

我正在使用openCV为我的ios应用程序检测实时摄像机中的移动物体,但我不熟悉openCV的使用请帮助我.任何其他方式也欢迎.

- (void)viewDidLoad {
    [super viewDidLoad];

    self.videoCamera.delegate = self;
    self.videoCamera = [[CvVideoCamera alloc] initWithParentView:self.view];

    self.videoCamera.defaultAVCaptureDevicePosition = AVCaptureDevicePositionBack;
    self.videoCamera.defaultAVCaptureSessionPreset = AVCaptureSessionPreset352x288;
    self.videoCamera.defaultAVCaptureVideoOrientation = AVCaptureVideoOrientationPortrait;
    self.videoCamera.defaultFPS = 30;
    self.videoCamera.grayscaleMode = NO;
    [self.videoCamera start];
//    cv::BackgroundSubtractorMOG2 bg;

}
- (void)processImage:(cv::Mat&)image
{
    //process here
    cv::cvtColor(image, img, cv::COLOR_BGRA2RGB);
    int fixedWidth = 270;
    cv::resize(img, img, cv::Size(fixedWidth,(int)((fixedWidth*1.0f)*   (image.rows/(image.cols*1.0f)))),cv::INTER_NEAREST);

    //update the model
   bg_model->operator()(img, fgmask, update_bg_model ? -1 : 0);


    GaussianBlur(fgmask, fgmask, cv::Size(7, 7), 2.5, 2.5);
    threshold(fgmask, fgmask, 10, 255, cv::THRESH_BINARY);

    image = cv::Scalar::all(0);
    img.copyTo(image, fgmask);
}

我是openCV的新手,所以我不知道该怎么办.
