Lists all fonts installed on iOS. Helpful to get the correct name when using custom fonts in an app 
func printFonts() {
    println("--- Installed fonts ---")
    let families = sorted(UIFont.familyNames() as! [String]) { $0 < $1 }

    for family in families {
        println("family: \(family)")

zachwaugh / ZWDictionaryOfVariableBindings.m
Last active July 29, 2016 12:39
Experiment to figure out how NSDictionaryOfVariableBindings works, and try to make a more flexible version. This version strips underscores and supports self.* variables, but I'm sure there is a better way to do it.
#import <Foundation/Foundation.h>
// Experimental improvement to NSDictionaryOfVariableBindings where keys are simplified to remove underscores and "self." prefixes
// so you can use the simple version within the VFL string
//
// Example:
//
// [NSLayoutConstraint constraintsWithVisualFormat:@"|-[_foo]-[self.bar]-[baz]" options:0 metrics:nil views:NSDictionaryOfVariableBindings(_foo, self.bar, baz)];
// -> this doesn't work, gives an error about "self."
