dynamic initialize any objective C class with property

Question

Can we initalize dynamically any Modal class. rather than creating any NSObject class with property values as likes string inside that class.

default we do code as like: in .h file

@interface MyUser : NSObject
@property (nonatomic, strong) NSString *username,*bio,*website;
@end

in .m file

@implementation InstaUser
@synthesize bio;
@end

To use that we do:

MyUser *sendUser = [[MyUser alloc]init];
sendUser.username = @"JHON";
sendUser.bio = @"abcdcskdfhksfjhfkjsdf";

I Don't want to create so many this type of modal class rather then this just any dynamic method to initalize class property and use it by inline code.

I have edited the question can any one have idea about this ? thanks in adv — Esha, Jun 25 '14 at 09:42
Hi Shreeji u mean to say that you want to set all the properties of a class at one shot, i mean using one method ? — iamyogish, Jun 25 '14 at 09:46
sounds like `NSMutableDictionary` with strong typed value accessors or CoreData model classes. give some code of what you want — Bryan Chen, Jun 25 '14 at 09:47
@iamyogish . yes at one shot. Not a single method but at-least from the single class at the time of using the instance. — Esha, Jun 25 '14 at 09:49

I think you meant a flexible model object with dynamically declared properties something like this:

MyModel *user = [[MyModel alloc] init];
user.name = @"name";

MyModel *something = [[MyModel alloc] init];
something.dynamicProperty = @"blahblah";

If so, you cannot. Use NSMutableDictionary instead, or consider to generate model classes from a simple config file by some scripts.

You can use run time feature of objective c class. Create a single model class and add property to it dynamically at run time: For more reference :

How can I add properties to an object at runtime?

Thanks, using this I can add any number of property to my dynamic class: class_addProperty([SomeClass class], "name", attrs, 3); – Esha Jun 25 '14 at 10:16
