Is it possible to load a font from disk and use it during run-time?
If so, how/where do you store the fonts on the iphone/ipod/ipad for your app to use?
(To be clear, I'm not talking about adding the font as a resource at design-time. I'm asking about a way to allow a user to select a font file during run-time, loading it, and making it available for use.)
You should put them (.ttf, .otf) into your info-plist under UIAppFonts then you can "use" them with setFont: withSize:
You add your font as a resource, add it to your info.plist under Fonts provided by application (UIAppFonts) array, then use it as any embedded one.
Ok, in that case take a look at FontLabel project.
One thing though, looking through it's code - you can only get CGFontRef and with kind of voodoo work with it, no conversion between CGFontRef and UIFont really exists. See this question

I was wondering that how to load a TTF font from a absolute file path, not relative, which is usually done with
[UIFont fontWithName:#"xyz"];
In cocos2d we can do it by using CCLabelBMFont that takes file as parameter, but when use CCLabelTTF it takes the name of font, not the file name.
Is there any workaround to load an external font not embedded with the application but downloaded from some resource as per need ?
Yes, you can do this.
Just copy the font to your project and add this reference in your info.plist. Then you can reference the font name just like any other system font.
if I did well understand your question, maybe this post Can I embed a custom font in an iPhone application? will give you an answer.
So I'm able to use custom fonts by adding them to my Xcode project and info.plist like so:
http://iosdevelopertips.com/user-interface/load-and-access-custom-fonts.html
However, I tried adding another in the same way, but that UIFont doesn't seem to work for some reason. The UILabel just shows the default font setting. Is there a particular reason why one .ttf would work and another wouldn't?
As EmilioPelaez commented, font family names can sometimes be different from the file names. Using the NSLog technique NSLog(#"Fonts: %#", [UIFont familyNames]); can help to find out what the family name of added fonts is.
In my application i need to display arabic text with different custom fonts. I follow the scenario adding ttf files to info.plist.
As per above scenario i am successfully getting display text in different font style for ENGLISH text only. I am doing same thing for arabic font styles but here i am not getting. Why is going like that?
Please any one can help me
Thanks in Advance.
#Kareem , I took hint from Stackoverflow itself to load the fonts but could not get it working in first go. May be following steps can help you .
Add the font files to your project.
Make their entries in info.plist file
such as
you can now implement some method that loads your font somewhere in
application delegate
like
-(UIFont*) CustomFontWithSize:(float)size{
UIFont* customFont = [UIFont fontWithName:#"FX_Masa" size:size];
if(customFont == nil)
customFont = [UIFont systemFontOfSize:size];
return customFont;
}
If you notice then the name I have passes here is "FX_MASA" and not FX_MasaRegular , this was the point where I was wrong. The name that we need to use while fetching the font is the INSTALL NAME (Double click on the font to install the font on system and the name that appears in Font Book is the install name).
Hope this helps your problem as well. In case you come across any good method, please update here.
There is a nice UILabel extension in GitHub called "Font Label": https://github.com/zynga/FontLabel
This allows to load any TTF file and then draw ZLabel objects (ZLabel is an extension of UILabel) with this custom font. It is based on CoreGraphics and I tested with many custom fonts and proved to work correctly. I don't know of course the effect with arabic fonts, but it's worth a try and a feedback from you (to us and also the github project admins) is welcome.
Just wondering what is the best way to display a barcode given a string on the iPhone. I have looked over stackoverflow and google and a few people have different ways each requiring a decent amount of work (I think) and also slightly old so I wanted to get it right first time.
One way I've read is using a custom font that you can now use in iOS4, using this font Someone else has written a class to import custom fonts, though this apparently isn't needed for iPads.
I have also found a Library but not much further details on it.
If using the font is the best way is the font linked above good or are there better ones?
Cheers for any help.
Well I went ahead and checked it out anyway. Fonts work extremely well and are very easy to implement. Basically copy this barcode font into your project. Then in your App info.plist type this in:
<key>UIAppFonts</key>
<array>
<string>3OF9_NEW.TTF</string>
</array>
For the above linked font.
Then in where you want to place the barcode just use a UILabel and then for the font use :
label.font = [UIFont fontWithName:#"3 of 9 Barcode" size:40];
Note that the font name is not 30F9_NEW.TTF. If you are using another barcode font or other font in general just open the ttf file in font book and it will say the name up the top of the window. Also you need to have a * at the beginning and end of the string you are using. If you navigated here looking at how to implement a custom font you can do it the same way, just not the font name isn't the file name.
I have a subclass of a UILabel that overloads initWithCoder and I was wondering if anyone has any documentation on how the coder is encoded so that I might be able to get information that comes from IB myself.
Thanks.
EDIT
Reason for doing this: I would like the font name given in the xib file. Apple's implementation of initWithCoder disregards the font name given in the file if it's a custom font and when you go to access the label's font, it returns the system font. Therefore I'd like to catch the font name before the original initWithCoder ignores it.
Looking through the documentation, there does not appear to be a way to retrieve all the keys used in an NSKeyedArchiver. One way "around" this is to archive your custom UILabel to an NSData object, write the data object out to a file, and then pop it open in a text editor and see if you can find some of the keys that way.
What information do you need from the UILabel that you can't access through its normal accessors?
If you look at the nib file compiled from the xib file for the interface you wanna decode, you'll be able to make out some of the keys you can use. It's kind of hard to find stuff, but it's better than nothing.
