Objective C Porting

[justmyself]

Wanting to develop for the iPhone I thought it would be good practice to develop it on the Mac first on 10.4 assuming I could cut and past most of the code. I decided to start simple with a high / low game. However I found several things that don't seem to work.


Here is the code that doesn't work.
[instructions setFont:[NSFont fontWithName:@"Times" size:14.0]];
[[NSSound soundNamed:@"click.wav"] play];
[myButton setTitle:@"Play again?"];

Strangely enough this doesn't work
[instructions setStringValue:@"Pick of a number between 1 and 10"];

however, this does
instructions.text=@"Pick a number between 1 and 10";

all the good stuff like setIntValue and setStringValue doesn't work. What's going on? Any help would be appreciated.

Thank you

What class is 'instructions'?

Also, 'instructions.text = ...' is the same as '[instructions setText:...]'.

Instructions is a UILabel.

UILabel won't respond to setStringValue. Class reference from the docs. (https://developer.apple.com/iphone/library/documentation/UIKit/Reference/UILabel_Class/Reference/UILabel.html)

With much searching and experimenting the following does work

[instructions setFont:[UIFont fontWithName:@"Helvetica" size:18.0]];

Still needing help with sound though. argh... something about Audio Queue Services???

Apples docs have always been difficult for me. I learn best with small simple examples. I'm working on it though. I did however find that the iPhone has a very limited set of fonts. Guess my only work around is an array of pictures of text. Crazy.

If all you need to do is *play* sound files then I would recommend using the AVAudioPlayer class from the AVFoundation framework. Audio Queue Services is very powerful, but very awkward to use and overkill if you don't need all that power.
