Delegate proxying (`protocol_methodForEach()` is a custom function that does just what its name implies)
@interface DDDelegateProxy : NSProxy
+ (id)proxyForDelegate:(id)delegate conformingToProtocol:(Protocol *)protocol;
@property (weak, readonly) id delegate;
@property (strong, readonly) Protocol *protocol;
/*!
* Set a default return value for a method on the delegate's protocol.
* \param value This must be a block that returns the default value. Bad Things will happen if it's not.

Making sure I get how base-64 encoding works.
int main(int argc, const char * argv[]) {
@autoreleasepool {
NSString *str = @"Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding.";
NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];
char table[] = {
'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P',

A straight-forward way to inject NSViewControllers into the AppKit responder chain
@interface DDControlledView : NSView
@property (weak) IBOutlet NSViewController *viewController;
@end
@implementation DDControlledView
- (void)setNextResponder:(NSResponder *)aResponder {
NSViewController *controller = self.viewController;
