ios_bind_fix.js

if (!Function.prototype.bind) {
	Function.prototype.bind = function(context) {
		var original_function = this;
		var curry_arguments = Array.prototype.slice.call(arguments, 1);
		return function() {
			var total_arguments = curry_arguments.concat(Array.prototype.slice.call(arguments, 0));
			return original_function.apply(context, total_arguments);
		};
