iOS Font loading problem

Helle every one !

I have added din.otf font in my iOS pro开发者_开发问答ject. Then in my plist I have :

Now when I want to use it I juste have to write this line :

lalel.font = [UIFont fontWithName:@"din" size:12.f];

Am I right ? It doen't work at all ... Thanks !

Try to list all fonts that are available on your device after importing by adding this piece of code :

// List all fonts on iPhone
  NSArray *familyNames = [[NSArray alloc] initWithArray:[UIFont familyNames]];
  NSArray *fontNames;
  NSInteger indFamily, indFont;
  for (indFamily=0; indFamily<[familyNames count]; ++indFamily)
  {
      NSLog(@"Family name: %@", [familyNames objectAtIndex:indFamily]);
      fontNames = [[NSArray alloc] initWithArray:
          [UIFont fontNamesForFamilyName:
          [familyNames objectAtIndex:indFamily]]];
      for (indFont=0; indFont<[fontNames count]; ++indFont)
      {
          NSLog(@"    Font name: %@", [fontNames objectAtIndex:indFont]);
      }
      [fontNames release];
  }
  [familyNames release];

And try to search for your font name.

I've found a way to load font at runtime which does not involve to add it on the .plist file.

+ (void)loadFontAtPath:(NSString*)path
{
    NSData *data = [[NSFileManager defaultManager] contentsAtPath:path];
    if(data == nil)
    {
#ifdef DEBUG
        NSLog(@"Failed to load font. Data at path is null path = %@", path);
#endif //ifdef Debug
        return;
    }
    CFErrorRef error;
    CGDataProviderRef provider = CGDataProviderCreateWithCFData((CFDataRef)data);
    CGFontRef font = CGFontCreateWithDataProvider(provider);
    if(!CTFontManagerRegisterGraphicsFont(font, &error)){
#ifdef DEBUG
        CFStringRef errorDescription = CFErrorCopyDescription(error);
        NSLog(@"Failed to load font: %@", errorDescription);
        CFRelease(errorDescription);
        return;
#endif //ifdef Debug
    }
    CFStringRef fontName = CGFontCopyFullName(font);
    NSLog(@"Loaded: %@", fontName);
    [[self sharedInstance] addFont:font withName:(NSString *)fontName];

    CFRelease(fontName);
    CFRelease(font);
    CFRelease(provider);
}

+ (void) unloadFont:(NSString*) fontName
{
    CFErrorRef error;
    CGFontRef fontref = [[self sharedInstance] getFontWithName:fontName];
    if(fontref)
    {
        CTFontManagerUnregisterGraphicsFont(fontref, &error);
        [[self sharedInstance] removeFontWithName:(NSString *)fontName];
    }
    else
    {
        NSLog(@"WARNING: Font cannot be unloaded: %@", fontName);
    }
}

And you can just use the name that NSLog(@"Loaded: %@", fontName); output.
