IOS在PDF中嵌入字体

Question

我正在绘制一个PDF文件,无法弄清楚如何将字体嵌入PDF本身,任何人都可以帮助我吗？它在设备上显示正常但是一旦通过电子邮件发送或通过AirPrint打印我就会得到后备字体.这是我的代码......

- (void) drawChart{
CGContextRef    currentContext = UIGraphicsGetCurrentContext();
CGContextSetRGBFillColor(currentContext, 0.0, 0.0, 0.0, 1.0);


NSUserDefaults *data = [NSUserDefaults standardUserDefaults];
NSString *pChart1 = [data stringForKey:@"pchart1"];


NSString *textToDraw = [NSString stringWithFormat:@"%@",pChart1];

UIFont *font = [UIFont fontWithName:@"MyFont" size:14];

CGSize stringSize = [textToDraw sizeWithFont:font
                           constrainedToSize:CGSizeMake(pageSize.width - 2*kBorderInset-2*kMarginInset, pageSize.height - 2*kBorderInset - 2*kMarginInset) 
                               lineBreakMode:UILineBreakModeWordWrap];

CGRect renderingRect = CGRectMake(kBorderInset + kMarginInset, kBorderInset + kMarginInset + 50.0, pageSize.width - 2*kBorderInset - 2*kMarginInset, stringSize.height);

[textToDraw drawInRect:renderingRect 
              withFont:font
         lineBreakMode:UILineBreakModeWordWrap
             alignment:UITextAlignmentLeft];
}

任何帮助将非常感激!

我不知道为什么,但是,在我参与的应用程序中,我们遇到了这个问题,一旦我们从使用开放式字体转换为真正的字体,它就可以工作了.
