Have you got tried of implementing methods initWithCoder: and encodeWithCoder: by yourself? With DYCoding, you don't need to implement those anymore, the encoding/decoding works dynamically in the runtime.
If a class is subclass from DYCodingObject, it will get the dyanmically encoding/decoding for free.
@interface MyModelObject : DYCodingObject
@property (nonatomic, readonly, copy) NSString *name;
@property (nonatomic, readonly, assign) NSInteger age;
@end
Since objective-c class can only have one super class, if your class can't subclass from DYCodingObject, you can put the macro DY_CLASS_IMPL in your class's implemention section, then your class will get the dyanmically encoding/decoding for free.
@implementation MyModelObject
DY_CLASS_IMPL
...
@end
You can refer the unit tests in DYCodingTests.m for the examples.
There are three ways to use DYCoding in your project:
- Importing the project to your workspace, add the corresponding target to your project as a static library
- Copying all the files into your project
- Using CocoaPods
platform :ios, '7.0'
pod 'DYCoding', '~>1.0'
- iOS
- OS X
- watchOS
- tvOS
This library supports dynamically encode/decode the object which contains the following property types, assertion will throw if it contains an unsupported property type.
- All primitive types.
- Objects which conforms to
NSCodingprotocol. - Some pre-defined structs: CGPoint, CGSize, CGRect, NSRange, UIOffset, UIEdgeInsets.
Although the encoding/decoding happens dynamically, it's performance should be as fast as the precompiled code due to the optimizations we have done. We are not doing the expensive reflection operation (class_copyIvarList) everytime, instead we only do it once per class, then use imp_implementationWithBlock and class_addMethod to add the implementation to the class.
