# iOS-Extensions
A library of useful extensions. Contains a lot of boiler plate code for iOS projects.
## Categories
`UIDevice+isIPAD{.h,.m}`
`UILabel+Font{.h,.m}`
`UIScreen+Frame{.h,.m}`
`UIView+Frame{.h,.m}`
`UIView+Xib{.h,.m}`
`UIViewController+Xib{.h,.m}`
`NSManagedObject+Map{.h,.m}`
`NSManagedObject+Extension{.h,.m}`
`NSString+KeyPath{.h,.m}`
#### UIDevice+isIPAD
This extension makes it easy to check if device is an iPad
```objc
[UIDevice MG_isIPAD];
```
#### UILabel+Font
This extension makes it easy to set/get font and fontSize
```objc
@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.
```objc
+ (CGRect) MG_screenRect;
```
#### UIView+Frame
This extension makes it easy to set/get attributes to/from a UIView.
```objc
@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:
```objc
CGRect frame = self.view.frame;
frame.origin.x = 50.0f;
self.view.frame = frame;
```
When you can do this:
```objc
self.view.x = 50.0f;
```
#### UIView+Xib
This extension makes it easy to init UIViews from Xibs.
```objc
- (id) MG_initWithNib;
```
#### UIViewController+Xib
Like *UIView+Xib*, This extension *also* makes it easy to init UIViewControllers from Xibs.
```objc
- (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.
```objc
//Example of a json response (Taken from foursquare)
/*
{
"id":"42377700f964a52024201fe3",
"name":"Brooklyn Heights Promenade",
"contact":{
},
"location":{
"address":"Columbia Heights",
"crossStreet":"btwn Remsen & Orange",
"lat":40.69829137715981,
"lng":-73.99663209915161,

}
*/
+ (instancetype) venueWithJSON:(NSArray*)json context:(NSManagedObjectContext*)context {
NSDictionary *map = @{
@"id" : kVenuePrimaryKey,
@"name": @"name",
@"canonicalUrl": @"canonicalUrl",
@"verified": @"verified",
@"location.address": @"address",
@"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:
```objc
+ (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.
```objc
- (BOOL) MG_isKeyPath;
```
