shaps80 / SLBarButtonItem.h
Last active December 18, 2015 14:29
I've often found myself a more convenient way to add a simple barButtonItem to a navigation or tool bar, so I created this nice little subclass.
#import <UIKit/UIKit.h>
@class SLBarButtonItem;
typedef void (^SLBarButtonItemCompletionBlock)(SLBarButtonItem *sender);
@interface SLBarButtonItem : UIBarButtonItem
+(SLBarButtonItem *)barButtonSystemItem:(UIBarButtonSystemItem)systemItem;
+(SLBarButtonItem *)barButtonWithTitle:(NSString *)title style:(UIBarButtonItemStyle)style;

Custom macros to provide better handling of encoding and decoding values. See my blog post for more detailed information: http://shaps.me/to-encode-or-to-decode

shaps80 / Logging.h
Last active January 3, 2016 21:39
Provides better logging with pretty formatting custom timestamp formatting. Fully customisable, and easy drop in replacement to start tidying up existing logs. No additional or frameworks required! Simply replace all NSLog occurrences with SPXLog and watch the logs get prettier! ;)
#import <Foundation/Foundation.h>
#ifdef __SPXLOGGING
#define __SPXLOGGING
/**
* Custom C function for getting the current date/time.
* This function provides custom formatting and is much faster than using
* NSDate and NSDateFormatter, which a lot of log messages are sent.
* Also this way there's little additional memory overhead during logging.

shaps80 / InitWithException.m
Created January 22, 2014 16:47
ProTip: Better way to raise an exception when -init is called on a class that implements a designated initialiser. Turn on -Wstrict-selector-match to get compiler warnings when this selector doesn't exist. Some IDEs (like AppCode) will even refactor this for you should you change the selector ;) The best thing about this is if its inside a stati…
- (instancetype)init
{
SEL selector = @selector(initWithName:);
[NSException raise:NSGenericException format:@"Please use %@", NSStringFromSelector(selector)];
return nil;
}
- (instancetype)initWithName:(NSString *)name
{
self = [super init];
