İşte çözüm. Bu işlevler Çekirdek Metin lehine kaldırılmıştır. Çok daha gelişmiş ama anlamaya biraz zaman alıyor. Bu örnek "Merhaba Dünya!" Courier yazı tipini kullanarak.
- (void)drawRect:(CGRect)rect
{
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSaveGState(context);
CFStringRef font_name = CFStringCreateWithCString(NULL, "Courier", kCFStringEncodingMacRoman);
CTFontRef font = CTFontCreateWithName(font_name, 36.0, NULL);
CFStringRef keys[] = { kCTFontAttributeName };
CFTypeRef values[] = { font };
CFDictionaryRef font_attributes = CFDictionaryCreate(kCFAllocatorDefault, (const void **)&keys, (const void **)&values, sizeof(keys)/sizeof(keys[0]), &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks);
CFRelease(font_name);
CFRelease(font);
int x = 10;
int y = 10;
const char *text = "Hello World!";
CFStringRef string = CFStringCreateWithCString(NULL, text, kCFStringEncodingMacRoman);
CFAttributedStringRef attr_string = CFAttributedStringCreate(NULL, string, font_attributes);
CTLineRef line = CTLineCreateWithAttributedString(attr_string);
CGContextSetTextPosition(context, x, y);
// Core Text uses a reference coordinate system with the origin on the bottom-left
// flip the coordinate system before drawing or the text will appear upside down
CGContextTranslateCTM(context, 0, self.bounds.size.height);
CGContextScaleCTM(context, 1.0, -1.0);
CTLineDraw(line, context);
CFRelease(line);
CFRelease(string);
CFRelease(attr_string);
CGContextRestoreGState(context);
}
