How to cache or preload SKLabelNode font?

Question

I\'m making a Sprite Kit app and in my scene I added an SKLabelNode. I noticed a pretty large lag-spike when I load the SKScene. After profiling the app I found it came from

Answer 1

I had the same issue. Add following code to your very first scene, with your font name:

SKLabelNode *preload = [SKLabelNode labelNodeWithFontNamed:@"Avenir"];
preload.text = @"text";

If you don't provide text it won't load font. Note that you don't need to add label as child to your scene.

Answer 2

We had this issue, and it turned out that we were simply not using the "correct" font name. In our case, we were using "Menlo" instead of "Menlo-Regular" when instantiating our SKLabelNode, and it was incurring the several-second penalty. Once we used the correct font name, the delay no longer happened.

(Curiously, the SKLabelNode still found Menlo and used it, so it was not immediately obvious that we had the wrong font name. Presumably, the delay is caused by the system having to figure out the appropriate substitute to use. It does a good job, finding the font we intended to use, but it takes a while to do it, hence the delay.)
