    text
    copied!<p>I am using a custom font applied to a CATextLayer. I am using the tutorial and sample code found here. <a href="http://www.freetimestudios.com/2010/09/13/custom-fonts-on-the-ipad-and-ios-4/" rel="noreferrer">http://www.freetimestudios.com/2010/09/13/custom-fonts-on-the-ipad-and-ios-4/</a></p> <p>However, every so often, I get the following error. Nothing in particular seems to trigger it. Can someone shed some light as to what this means? What to check for?</p> <pre><code>CoreText: Invalid 'kern' Subtable In CTFont &lt;name: Intellect, size: 20.000000, matrix: 0x0&gt; CTFontDescriptor &lt;attributes: &lt;CFDictionary 0xac07a80 [0x38295d98]&gt;{type = mutable, count = 1, capacity = 3, pairs = ( 0 : &lt;CFString 0x3833f750 [0x38295d98]&gt;{contents = "NSFontNameAttribute"} = &lt;CFString 0x159af0 [0x38295d98]&gt;{contents = "Intellect"} </code></pre> <p>I load the font using the following code. This code is taken from the project in the link above.</p> <pre><code>- (CTFontRef)newCustomFontWithName:(NSString *)fontName ofType:(NSString *)type attributes:(NSDictionary *)attributes { NSString *fontPath = [[NSBundle mainBundle] pathForResource:fontName ofType:type]; NSData *data = [[NSData alloc] initWithContentsOfFile:fontPath]; CGDataProviderRef fontProvider = CGDataProviderCreateWithCFData((CFDataRef)data); [data release]; CGFontRef cgFont = CGFontCreateWithDataProvider(fontProvider); CGDataProviderRelease(fontProvider); CTFontDescriptorRef fontDescriptor = CTFontDescriptorCreateWithAttributes((CFDictionaryRef)attributes); CTFontRef font = CTFontCreateWithGraphicsFont(cgFont, 0, NULL, fontDescriptor); CFRelease(fontDescriptor); CGFontRelease(cgFont); return font; } </code></pre>
