armadsen / FunctionPointerFromMethod.m
Created May 19, 2012 18:50
Simple example of getting a function pointer to an Objective-C method and calling it
// To compile and test this from the command line:
//
// $> clang FunctionPointerFromMethod.m -ObjC -framework Foundation -fobjc-arc
// $> ./a.out
#import <Foundation/Foundation.h>
@interface MyClass : NSObject
- (void)someMethodThatTakesOneStringArgument:(NSString *)string;

armadsen / MethodInProtocolsRequiredExample.m
Last active December 10, 2015 04:28
Complete example/test program for quick and dirty function to determine if a method in an Objective-C protocol is required or optional. Example for my answer to this stackoverflow question: http://stackoverflow.com/questions/14043930/how-to-identify-a-protocol-method-is-optional-during-runtime/14044086#14044086
#import <Foundation/Foundation.h>
#import <objc/runtime.h>
@protocol TestProtocol <NSObject>
@required
- (void)methodA;
@optional
- (void)methodB;
@end

Created February 15, 2013 19:52
Quickly thrown together script to build libFLAC as a 64/32-bit universal binary on Mac OS X 10.8.
#!/usr/bin/env bash
# Put this script in the libFLAC source directory, and make sure it's executable (chmod +x BuildLibFlac.sh), then run it (./BuildLibFLAC.sh)
# Note that this was written to be used on 10.8 with Xcode 4.6 and FLAC 1.2.1. It may/will need to be changed for future versions of the OS, tools, and/or FLAC

armadsen / ORSSerialPort+Attributes.m
Last active July 11, 2018 13:44
Example code to get USB device properties for a given instance of ORSSerialPort. Will only work for USB-to-serial adapters, not internal serial ports. Based on https://gist.github.com/rhwood/4124251.

#import <IOKit/usb/USBSpec.h>
#import "ORSSerialPort.h"
@interface ORSSerialPort (Attributes)
@property (nonatomic, readonly) NSDictionary *ioDeviceAttributes;
@property (nonatomic, readonly) NSNumber *vendorID;
@property (nonatomic, readonly) NSNumber *productID;

Created June 21, 2013 17:49
Example of how I would do https://code.stypi.com/clifton/Objective-C/reusable.m if I were going to do it essentially the same way. In response to https://twitter.com/cliftonite/status/348133150880317440
- (void)makeGraphPopup:(NSString *)popupName {
/*
I want to pass a string (popupName) into this method and use it dynamically
for object names just like popupName.to_sym in Ruby.
Below you can see where I've insert {popupName} and how it would append itself
to various object names which are IBOutlets
