This is project in development. Its aim is to create drop-in replacement for NSKeyedArchiver and NSKeyedUnarchiver that produce archives in JSON format. These archives will preserve classes, cyclic references, conditional references and will use native JSON types as much as possible to produce pretty and compact results.
Actual result after encoding several keyed root objects:
var archiver = [JSONArchiver new];
archiver.shouldPrettyPrint = YES;
[archiver encodeObject:@"Lorem ipsum" forKey:@"title"];
[archiver encodeObject:nil forKey:@"subtitle"];
[archiver encodeInteger:2017 forKey:@"year"];
[archiver encodeBool:YES forKey:@"isWorking"];
[archiver encodeObject:URL forKey:@"website"];
NSLog(archiver.JSONString); // Result is below.{
"title" : "Lorem ipsum",
"subtitle" : null,
"year" : 2017,
"isWorking" : true,
"website" : {
"#url" : "https:\/\/developer.apple.com"
}
}More complex example with multiple objects and cyclic references:
// Standard object implementing NSCoding.
@implementation Person
- (void)encodeWithCoder:(NSCoder *)encoder {
[encoder encodeObject:self.name forKey:@"name"];
[encoder encodeInteger:self.age forKey:@"age"];
[encoder encodeObject:self.partner forKey:@"partner"];
[encoder encodeObject:self.children forKey:@"children"];
}
@end// Archive single root object.
[archiver encodeRootObject:@[person1, person2]];[
{
"#class" : "NSArray",
"#objects" : [
{ "#ref" : 1 },
{ "#ref" : 2 }
]
},
{
"#class" : "Person",
"age" : 45,
"name" : "Mom",
"partner" : { "#ref" : 2 },
"children" : { "#ref" : 3 }
},
{
"#class" : "Person",
"age" : 48,
"name" : "Dad",
"partner" : { "#ref" : 1 },
"children" : { "#ref" : 3 }
},
{
"#class" : "NSArray",
"#objects" : [
{ "#ref" : 4 },
{ "#ref" : 5 }
]
},
{
"#class" : "Person",
"age" : 8,
"name" : "Alex",
"partner" : null,
"children" : null
},
{
"#class" : "Person",
"age" : 4,
"name" : "Chris",
"partner" : null,
"children" : null
}
]Unarchiver is not yet implemented 😜
