BBNSButton.h

@interface BBNSButton : NSButton

Set the callback block to be called when the mouse enters the button.

- (void)setInCallback:(BBNSButtonCallback)block;

Set the callback block to be called when the mouse exits the button.

- (void)setOutCallback:(BBNSButtonCallback)block;

Set both the enter* and **exit callback blocks.

- (void)setInCallback:(BBNSButtonCallback)inBlock andOutCallback:(BBNSButtonCallback)outBlock;

BBlock.h

@interface BBlock : NSObject

For when you need a weak reference of an object, example: BBlockWeakObject(obj) wobj = obj;

For when you need a weak reference to self, example: BBlockWeakSelf wself = self;

Execute the block on the main thread

+ (void)dispatchOnMainThread:(void (^)())block;

Exectute the block on a background thread but in a synchronous queue

+ (void)dispatchOnSynchronousQueue:(void (^)())block;

Exectute the block on a background thread but in a synchronous queue,

This queue should only be used for writing files to disk.

+ (void)dispatchOnSynchronousFileQueue:(void (^)())block;
+ (void)dispatchOnDefaultPriorityConcurrentQueue:(void (^)())block;
+ (void)dispatchOnLowPriorityConcurrentQueue:(void (^)())block;
+ (void)dispatchOnHighPriorityConcurrentQueue:(void (^)())block;

NSApplication+BBlock.h

@interface NSApplication (BBlock)

- (void)beginSheet:(NSWindow*)sheet modalForWindow:(NSWindow*)modalWindow completionHandler:(void (^)(NSInteger returnCode))handler;

NSArray+BBlock.h

@interface NSArray(BBlock)

Enumerate each object in the array.

- (void)enumerateEachObjectUsingBlock:(void(^)(id obj))block;

Apply the block to each object in the array and return an array of resulting objects

- (NSArray *)arrayWithObjectsMappedWithBlock:(id(^)(id obj))block;

NSButton+BBlock.h

@interface NSButton(BBlock)

WARNING: This category is still in early development. Currently the order of calling these methods is important:

  1. setImage
  2. setAlternateBackgroundImage
  3. setBackgroundImage

Tries to mimic UIButton by exposing a method to set the background image. The image set with setImage is composited on-top of the background image.

- (void)setBackgroundImage:(NSImage *)backgroundImage;

Tries to mimic UIButton by exposing a method to set the alternate background image. The image set with setAlternateImage is composited on-top of the alternate background image. If no alternateImage is set image will be used instead.

- (void)setAlternateBackgroundImage:(NSImage *)alternateBackgroundImage;

NSDictionary+BBlock.h

@interface NSDictionary(BBlock)

Enumerate each key and object in the dictioanry.

- (void)enumerateEachKeyAndObjectUsingBlock:(void(^)(id key, id obj))block;
- (void)enumerateEachSortedKeyAndObjectUsingBlock:(void(^)(id key, id obj, NSUInteger idx))block;

NSImage+BBlock.h

@interface NSImage(BBlock)

Returns a NSImage rendered with the drawing code in the block. This method does not cache the image object.

+ (NSImage *)imageForSize:(NSSize)size withDrawingBlock:(void(^)())drawingBlock;

Returns a cached NSImage rendered with the drawing code in the block. The NSImage is cached in an NSCache with the identifier provided.

+ (NSImage *)imageWithIdentifier:(NSString *)identifier forSize:(NSSize)size andDrawingBlock:(void(^)())drawingBlock;

NSObject+BBlock.h

@interface NSObject(BBlock)

- (NSString *)addObserverForKeyPath:(NSString *)keyPath options:(NSKeyValueObservingOptions)options block:(NSObjectBBlock)block;
- (void)removeObserverForToken:(NSString *)identifier;

NSTimer+BBlock.h

@interface NSTimer(BBlock)

+ (id)timerWithTimeInterval:(NSTimeInterval)timeInterval andBlock:(void (^)())block;
+ (id)timerRepeats:(BOOL)repeats withTimeInterval:(NSTimeInterval)timeInterval andBlock:(void (^)())block;
+ (id)scheduledTimerWithTimeInterval:(NSTimeInterval)timeInterval andBlock:(void (^)())block;
+ (id)scheduledTimerRepeats:(BOOL)repeats withTimeInterval:(NSTimeInterval)timeInterval andBlock:(void (^)())block;

NSURL+BBlock.h

@interface NSURL(BBlock)

Access a security scoped bookmark for sandboxed mac apps.

This method starts the access, runs the block, then stops the access.

-(void)accessSecurityScopedResourceWithBlock:(void (^)())block;

SKProductsRequest+BBlock.h

@interface SKProductsRequest(BBlock)

Request a StoreKit response for a set of product identifiers

+ (id)requestWithProductIdentifiers:(NSSet *)productIdentifiers andBlock:(SKProductsRequestBBlock)block;
- (id)initWithProductIdentifiers:(NSSet *)productIdentifiers andBlock:(SKProductsRequestBBlock)block;

- (void)addActionForControlEvents:(UIControlEvents)events withBlock:(BBlockUIButtonBlock)block;

UIGestureRecognizer+BBlock.h

@interface UISwipeGestureRecognizer(BBlock)

- (id)initWithDirection:(UISwipeGestureRecognizerDirection)direction andBlock:(UIGestureRecognizerBBlock)block;
+ (id)gestureWithDirection:(UISwipeGestureRecognizerDirection)direction andBlock:(UIGestureRecognizerBBlock)block;

@interface UIGestureRecognizer(BBlock)

- (id)initWithBlock:(UIGestureRecognizerBBlock)block;
+ (id)gestureWithBlock:(UIGestureRecognizerBBlock)block;

UIImage+BBlock.h

@interface UIImage(BBlock)

Returns a UIImage rendered with the drawing code in the block. This method does not cache the image object.

+ (UIImage *)imageForSize:(CGSize)size withDrawingBlock:(void(^)())drawingBlock;
+ (UIImage *)imageForSize:(CGSize)size opaque:(BOOL)opaque withDrawingBlock:(void(^)())drawingBlock;

Returns a cached UIImage rendered with the drawing code in the block. The UIImage is cached in an NSCache with the identifier provided.
