Let's say you want to find the index in the array of the object you just created. If you use indexOfObject:[NSNumber numberWithInt:7] that wouldn't work, right?

Re: Integer as key in NSMutableDictionary
Thanks all for the replies. I clearly understand now that I should use NSNumber instead of NSInteger. However, another question came up: when I use the removeObjectForKey, how can I make a reference to a specific key? Let's say I want to remove key that was initialized with [NSNumber numberWithInt:1]. If I call removeObjectForKey:[NSNumber numberWithInt:1], that method won't work because a new NSNumber pointer is being created, correct?The only solution I could find is to use enumeration and go through each key and gets its integer value.

Integer as key in NSMutableDictionary
Hi,
Assume that:
NSMutableDictionary *result = [[NSMutableDictionary alloc]
initWithCapacity:10];
NSInteger ID;
And I add objects to the dictionary:
[result setObject:[NSArray arrayWithObjects: {... objects ...}
nil]
forKey:ID];
I am getting warnings when adding integers in the array and assigning
the integer ID as a key. The code does work though, but I am guessing
there is a better way to accomplish what I want. I know that these
methods are expecting pointers as parameters and I am passing a
scalar. So, what's the best way to approach that?
Thank you

Loading a view controller from a tab bar controller
Hello there, Another noob question that I couldn't find a solution yet. In my mainwindow xib file, I have a tab bar controller which has two different view controllers. However, when I create those view controllers, how can I set the view property to a view controller instead of just a view? IB doesn't let me to drag the view property of the File Owner to a view controller. Instead, it only lets me to drag it to a UIView. But that doesn't accomplish what I want - which is to load a ViewController. Any ideas? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Two view controllers in one set of files (Noob question)
Thanks for the replies. I looked around the net and found some tutorials on how to create multiple views in a single nib file. I was just confused on how to do that. But you are right, it's better to have unique classes files for each views.

Windows vs View
Hi there, This is my first message here and I am already starting with a very newbie question. I have a broad understanding what a view is - a button, a label, etc... are views, right? But when I look at some sample codes from Apple, the application doesn't have a "main" window.. instead, it has a view and a view controller. So, what's the difference between a window and a view? Can an application have no window but multiple views? Thanks, Weydson ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
