A library of useful extensions. Contains a lot of boiler plate code for iOS projects.

UIDevice+isIPAD

This extension makes it easy to check if device is an iPad

[UIDevice MG_isIPAD];

UILabel+Font

This extension makes it easy to set/get font and fontSize

@property (nonatomic) NSString *fontName;
@property (nonatomic) CGFloat fontSize;

UIScreen+Frame

This extension makes it easy to get the correct screen size based on the device’s orientation.

+ (CGRect) MG_screenRect;

UIView+Frame

This extension makes it easy to set/get attributes to/from a UIView.

@property (nonatomic) CGFloat x;
@property (nonatomic) CGFloat y;
@property (nonatomic) CGFloat width;
@property (nonatomic) CGFloat height;
@property (nonatomic, readonly) CGFloat bottom;
@property (nonatomic, readonly) CGFloat right;

@property (nonatomic) CGSize size;

@property (nonatomic) CGFloat centerX;
@property (nonatomic) CGFloat centerY;

So why do this:

CGRect frame = self.view.frame;
frame.origin.x = 50.0f;
self.view.frame = frame;

When you can do this:

self.view.x = 50.0f;

UIView+Xib

This extension makes it easy to init UIViews from Xibs.

- (id) MG_initWithNib;

UIViewController+Xib

Like UIView+Xib, This extension also makes it easy to init UIViewControllers from Xibs.

- (id) MG_initWithNib;

NSManagedObject+Map

This extension makes it easy to parse a JSON Object into Core Data via a NSDictionary mapping.

Use the . separator to suggest key path values. See example below.

//Example of a json response (Taken from foursquare)
/*

+ (instancetype) venueWithJSON:(NSArray*)json context:(NSManagedObjectContext*)context {

    NSDictionary *map = @{
                          @"id" : kVenuePrimaryKey,
                          @"name": @"name",

                          @"location.crossStreet": @"crossStreet",
                          @"location.lat": @"latitude",
                          @"location.lng": @"longitude",
                          @"location.distance": @"distance",
                          @"location.postalCode": @"postalCode",
                          @"location.city": @"city",
                          @"location.state": @"state",
                          @"location.country": @"country",
                          @"location.cc": @"cc",
                          };

    return [self MG_objectWithJSON:json primaryKey:kVenuePrimaryKey map:map context:context];    
}

You can also fetch an object based on its primary key value via:

+ (instancetype) MG_objectWithPrimaryKey:(NSString*)primaryKey primaryValue:(id)primaryValue context:(NSManagedObjectContext*)context

NSString+KeyPath

This extension makes it easy to check whether or not a string is a key path or not. This was really build as a helper method for NSManagedObject+Map extension, but you may find it useful in other situations.

- (BOOL) MG_isKeyPath;
