Hi i want to develop a simple apps for comic books. first page will have categories and respective pages will have comics. each page will have text and images.
As with all books, i would want page flipping without any navigation buttons. I am new to Iphone programming. How can i develop this simple apps quickly? Thanks for your help.
Just imagine I read it twice. While I am not as accomplished on this subject, I match with your closings because they make sense. Gives Thanks and goodluck to you.

Hi Piotrek!
For sure one day I will find some free time to finish them, but it’s really difficult for a guy with so many things on his head – talking about me right know.
As you mentioned, everything about tables tutorial is finished, but since 3.0 some things changed, like not cell.text, but cell.textLabel.text and so on.
Regards
Chris

hi, i wrote an app in the same complicated way.
could you please give an example how to alloc several sounds once?
bell_left_Sound = [[SoundEffect alloc] initWithContentsOfFile:[mainBundle pathForResource:@"bell_left" ofType:@"caf"]];
bell_right_Sound = [[SoundEffect alloc] initWithContentsOfFile:[mainBundle pathForResource:@"bell_right" ofType:@"caf"]];
- (IBAction)bell_left: (id)sender {
SoundEffect *currentSoundEffect= bell_left_Sound;
[currentSoundEffect play];
}
- (IBAction)bell_right: (id)sender {
SoundEffect *currentSoundEffect= bell_right_Sound;
[currentSoundEffect play];
}
thanx 4 help
All sounds you have to create calling alloc method for every single one sound.
My hat to you. What a great site with some of the best tutorials and tips.
Really great site, which content helps me a lot.
Have you already thought of posting code examples which would cover graphic (or animation) and/or networking issues?

Hi James!
When I make my tutorials I don’t rewrite the documentation, but I try to share with you my opinions, best examples of using some classes or tricks. That means, I need to use on my own “the part of SDK” in the project, before I start talking about it. I develop, so I gain knowledge and experience that is required to talk about something and not to be called a noob, lame (no offence, I’m talking about me).
I’ve never need any graphics to be drawn using quartz 2d or using 3d in openSth. If you need, visit the sites linked in “For developers” category on the right.
Ok, I see!
Nethertheless I’m still looking forward to new code examples from you covering other issues.
In the meantime your “For developers” links helped me a lot.
Thanks!
That was exactly what im looking for. Really great site with a good tutorial.
Continue pls with it!

Sure, I will, soon I will publish sth bigger about UITextField. if you have ideas, send them to me. Regards, Chris.
Chris,
you’ve built yourself a great site. I’ve spend several hours here today and I’ll most likely come back.
Igor
Thanks
have a nice day
