Unable to get values from NSDictionary is ios

My NSDictionary output with NSLog shows:

{
    "filename" : "mytest100.txt",
    "filedesc" : "File Description here",
    "data" : [

    ]
 }

But when I do: NSString *filename = [dict objectForKey:@"filename"]; it crashes on this line.

What am I doing wrong? This seems trivial.

Try this:

NSDictionary *d = [NSDictionary dictionaryWithObject:@"foo" forKey:@"bar"];
NSLog(@"%@", d);

output is:

{
    bar = foo;
}

Notice that there are no quotes logged in the key or value? Unless your key and value is of the form @"\"foo\"", my guess is that you don't really have a dictionary there.

I'd put my money on a string representing JSON. The crash is because objectForKey: is an unrecognized selector on a string.

From the error message you're getting, the dict variable does not hold an NSDictionary, but rather and NSString.

Track back up your code looking for where you assign the dict variable and you'll surely see it's being set to something that's not a dictionary.
