HKHelperKit fixes some annoyances when developing Objective-C applications. Mostly it just adds some methods to SDK classes to make them easier and less verbose to use.

1. Clone this repository into a HKHelperKit subfolder within your project.
2. Drag the HKHelperKit folder into XCode.
3. Now simply use #include "HKHelperKit.h" anywhere that you want to use HKHelperKit methods.

HKHelperKit enhances the following classes in the following ways:

• [NSString stringFromResource:@"MyFile.html"]; loads an app resource from teh main bundle with teh provided file name into an autoreleased string.
• Simple search methods
  • [@"foobar" conatinsString:@"oob"];
  • [@"foobar" startsWithString:@"foo"];
  • [@"foobar" endsWithString:@"bar"];
• [someString isPresent]; method that is shorthand for: string != nil && ![string isEqualToString:@""];.
• [@"foobar" compareCaseInsensitive:@"FooBAR"];
• NSData conversion
  • [NSString stingWithData:someNSDataObject];
  • [NSString stingWithData:someNSDataObject encoding:NSASCIIStringEncoding];
  • [@"foobar" data]
• [@"foo/space here" stringByEscapingURL] => @"foo%2Fspace%20here"
• [@"foo/space here" stringByPercentEscapingCharacters:@" "] => @"foo/space%20here"

• [UIAlertView showSimpleAlertWithTitle:@"A Title" message:@"A Message!"]; Shows an alert with an OK button
• [UIAlertView showSimpleAlertWithTitle:@"A Title" message:@"A Message!" buttonTitle:@"Not OK"]; Shows an alert with a single custom button title

• Convenience Initializers
  • [UIBarButtonItem itemWithSystemType:UIBarButtonSystemItemAdd];
  • [UIBarButtonItem itemWithSystemType:UIBarButtonSystemItemAdd target:object action:@selector(someSelector)];
  • [UIBarButtonItem itemWithTitle:@"foobar" target:object action:@selector(someSelector)];
  • [UIBarButtonItem itemWithImage:someUIImage target:object action:@selector(someSelector)];
  • [UIBarButtonItem flexibleSpace];
  • [UIBarButtonItem fixedSpace:123];

• Added NSCoding support to UIImage
• [someImage imageByResizing:CGSizeMake(123, 456)];

• navigationController.backViewController read only property that works just like topViewController except it return the controller immediately preceding the top one (or nil).

• Convenience Initializers
  • [UIViewController controller];
  • [UIViewController controllerWithNib]; This loads the nib with the same name as the view controller class. [MyController controllerWithNib] is the same as [[[MyController alloc] initWithNibName:@"MyController" bundle:nil] autorelease]
  • [UIViewController controllerWithNibName:@"SomeNibName"];
  • [UIViewController controllerWithNibName:@"SomeNibName" bundle:someBundle];
  • [[UIViewController alloc] initWithNibName:@"SomeNibName"];
  • [[UIViewController alloc] initWithNib]; instance level initializer that works as described in the controllerWithNib class method.
