Question

I’m currently working with someone else code, so i have a question is there a way to quickly tell what objects i have in NSArray.

In code i have for example:

Someclassobj.arr

And i know there is an array as a property in Someclassobj and of course i can see the definition of it, but still dont know what objects are inside. Could be NSString, NSDictionary,ObjectDefinedByUSer… How to quicly tell?

There is a method to check classes? If i execute:

id someUnknownObj = [Someclassobj.arr objectAtIndex:0];

How to check it? (i know isKindOfClass isMemberOfClass methods, but its doesn’t work for me).

Of course there is doesn’t have to be code method, could be something like option+click.

Answer 1

Will do the trick:

NSLog(@"%@",yourArray);

If you want to avoid this kind of stuff:

1) Put a breakpoint as soon as the NSArray has the objects.

2) Go to the Console on Xcode and do:

po yourArray

A great article about using the console in Xcode here.
