store value in three dimensional NSMutableArrary

[losingSkillz]

Hi all:
I am just clearifying my previous post. I have 5 different mutable arrays that I am using to store my information that I use as rgb numbers. I also have 3 sliders (red, green, blue). I then update all of the ui controls with the new colour. The problem that I have is I do not know how to store/get values from the different arrays. Lastly, I also need to be able to save and load the arrays by using NSUserDefaults.

Thank you all for any advice or suggestions

can u provide any sample code because i am not familiar with nsdictionary? thank you very much.

[gunther]

for set

advertiset = [[[NSMutableDictionary alloc]init]autorelease];
		[advertiset setObject:currentAdvertise.ciudad forKey:@"ciudad"];

where current.Advertise.ciudad is for example a nsstring

for get

lblciudad.text = [advertiset objectForKey:@"ciudad"];

thanks for reply. but doesn't that require a seperate class? also, want to be able to store the rgb colours in the array. thank you again.

you can make the dictionary in a separatte class..for example Mydic and in MyDic you make the NSdictionary for set and get the rgb..

But i think what if you call this for others views you can make a plist and set and get this values more easy. and the advantage is what you can use the same data in all views..

Only need what make a class for sharing the code read a write plist and import to the view controller.

thanks for all the help. but i still have some other questions.
1:is there anyway to set the colour of the font of a button programmatically using [UIColour colourWithRed:redValue green:greenValue blue:blueValue];?
i know you can do this with a label but does it work for buttons too?

2:for the NSMutableDictionary, is it possible to have more than one object for one key? for example can you use something like this?:

[dictLabelFont setObject:[NSString stringWithFormat:@"%d", intRedColour] forKey:@"red"];
[dictLabelFont setObject:[NSString stringWithFormat:@"%d", intGreenColour] forKey:@"green"];
[dictLabelFont setObject:[NSString stringWithFormat:@"%d", intGreenColour] forKey:@"blue"];

actually for the second question i meant to say can you can store more than one object/key in a NSMutalbeDictionary right?
thanks for all of your help :-)

UIButton setTitleColor:forState:

yes, you can store any number of objects/keys in a NSMutableDictionary.

btw, if you want to store float values in a dictionary, you might consider using NSNumber numberWithFloat: instead of converting to/from strings all the time.
