FTGPropertyMaestro

Synthesize properties for categories

How I do it

• Swizzle getter and setter
• Using associated object

How to use it

• Import FTGPropertyMaestro and you're good to go
• Property with backing instance variable or not of object type are not supported

@property (nonatomic, assign) BOOL categoryBoolProperty;

This property is not supported because it is of type BOOL

@interface FTGClassA : NSObject

@property (nonatomic, strong) NSNumber *strongProperty;

@end

This property is not supported because it is not in category, it will be auto synthesized to have getter, setter and backing instance variable.

• Support custom getter and setter

@property (nonatomic, copy, setter = updateCategoryCopyProperty:) NSString *categoryCopyProperty;

• Set association type depends on your property attribute

@property (nonatomic, strong) NSNumber *categoryStrongProperty;

This will select OBJC_ASSOCIATION_RETAIN_NONATOMIC

• Remember to use @dynamic to suppress warning
• FTGPropertyMaestro will synthesize getter and setter for you, using associated object (Replace implementation if they exist, or add new implementation if they do not exist)

Property Retrieval

NSArray *kClassAProperties = [FTGPropertyMaestro propertiesForClass:[FTGClassA class]];

FTGProperty *wheelNumberProperty = [FTGPropertyMaestro propertyForClass:[FTGCar class]
                                        propertyName:@"wheelNumber"];

Synthesize property for category

FTGClassA+FTGAdditions.h

@interface FTGClassA (FTGAdditions)

@property (nonatomic, assign, getter = fetchCategoryBoolProperty) BOOL categoryBoolProperty;
@property (nonatomic, strong) NSNumber *categoryStrongProperty;
@property (nonatomic, copy, setter = updateCategoryCopyProperty:) NSString *categoryCopyProperty;

@end

FTGClassA+FTGAdditions.m

@implementation FTGClassA (FTGAdditions)

@dynamic categoryBoolProperty;
@dynamic categoryCopyProperty;
@dynamic categoryStrongProperty;

+ (void)load
{
    [FTGPropertyMaestro synthesizeClass:self propertyNames:@[ @"categoryCopyProperty", @"categoryStrongProperty"] ];
}

@end
