iphone Programming Glossary: encodewithcoderiPhone - Why does the documentation say UIImageView is NSCoding compliant? http://stackoverflow.com/questions/1072700/iphone-why-does-the-documentation-say-uiimageview-is-nscoding-compliant documentation say UIImageView is NSCoding compliant Ideally an NSCoding compliant class will work as expected using encodeWithCoder and initWithCoder at least I thought so till recently without the developer having to bother about what goes on inside the.. classes. But every time I try and encode a UIImageView object I get an error that UIImage does not recognize encodeWithCoder method. Now the UIImageView internally uses a UIImage object. But shouldn't the encoding have taken care of that itself.. compliance specified in the documentation to just let the user know that they can implement the initWithCoder and encodeWithCoder methods Can someone please clarify this for me I am thoroughly confused iphone uiimageview nscoding share improve this..
Can I encode a subclass of NSManagedObject? http://stackoverflow.com/questions/1371749/can-i-encode-a-subclass-of-nsmanagedobject it over the line then unarchive the object and I'm done. Of course I would need to implement the initWithCoder and encodeWithCoder methods in my custom object as well. I'm not sure if this can be done with an NSManagedObject class which is managed by..
Make a Custom Class Serializable in Objective-c/iPhone? http://stackoverflow.com/questions/2182115/make-a-custom-class-serializable-in-objective-c-iphone share improve this question You'll want to implement the NSCoding protocol . Implement initWithCoder and encodeWithCoder and your custom class will work with NSKeyedArchiver and NSKeyedUnarchiver. Your initWithCoder should look like this id.. decodeObjectForKey @ aString retain anotherString aDecoder decodeObjectForKey @ anotherString retain return self and encodeWithCoder void encodeWithCoder NSCoder encoder add super encodeWithCoder encoder if the superclass implements NSCoding encoder encodeObject.. @ aString retain anotherString aDecoder decodeObjectForKey @ anotherString retain return self and encodeWithCoder void encodeWithCoder NSCoder encoder add super encodeWithCoder encoder if the superclass implements NSCoding encoder encodeObject aString forKey..
