iOS 7 Critical failure: the LastResort font is unavailable

Question

When my app first launches I create a bunch of custom UIFonts (they are correctly added into the .plist). The custom fonts work perfectly until I try to create more than 9 to 10 of them. After the 9 or 10th custom font is created, I get this warning "Critical failure: the LastResort font is unavailable." I only get this warning on my iOS 7 devices and I can't seem to figure out why. This has to be a bug with iOS 7 because every custom font works on my iOS 6 devices, and I'm only using 1 project. Any idea what is causing this warning, and how to fix it?

Answer 1

It happened to me with iOS 7..I removed all the fonts and added carefully one by one to the plist. There was a font that was "bad" for iOS 7 and caused the mess. I hope this help) Of course a bug in Apple's Matrix
