Question

I would bet this is a very basic question, but i don’t get it!

I load some REST Data and put it in Objects in a NSMutableArray.

1. Load REST-Data
2. Parsing the Rest-Data to Objects
3. Add the Objects to a NSMutable Array

now i need to access some properties of the objects stored in the mutable array and i get Xcode errors, stating that there is no property with the given name in object of type “id”.

Could somebody give me a quick hint? I thought i could use the Objects and their properties within the NSMutable Array directly.

Thanks for your help!

You probably need to cast the objects in your mutable array, and not use the dot notation. As in

[anArray objectAtIndex:i].yourProperty; // will give you an error
[(YourClass*)[anArray objectAtIndex:i] yourProperty]; // should work
