» Settings.bundle checking error...really annoying |
|

Hey guys,
I have a settings.bundle that has a Multi Value Specifier that is working properly, I get the setting's value and all but when checking for the string's value it messes up.
For example, if I load the setting's value and display it in an Alert View, it shows the correct value. However, if I check for the setting's value in an if statement, it doesn't work. Here's some example code
Code:
NSString *selectedCarType = [[NSUserDefaults standardUserDefaults] stringForKey:@"default_car"];
/* This displays the correct value and everything ! */
UIAlertView *alert = [[UIAlertView alloc] initWithTitle: @"Setting Value"
message: selectedCarType
delegate:self ... [Read More]

or
2) A list of tunes on the device and then plays those tunes within the app
Anyone knows if these are possible?

» String to Integer |
|
Jul 04, 2009 - 2:36 AM - by Gimples
|
I want to be able to add one number to another. One of my numbers is an integer, the other is a string in an editable text field. The only problem I have little knowledge of Xcode and do not know the function to turn a string into an integer. Also, when I build my app, I get an error that says "warning implicit declaration of function degreesToRadians", I have no idea why it is giving me this error. Here is my code:
Code:
drawingPoint1 = CGPointMake(drawingPoint.x+cos(degreesToRadians(angle1))*100,drawingPoint.y+sin(degreesToRadians(angle1))*100);
Thanks

» Replicating the cool iPod landscape transition on the iPhone? |
|
Jul 04, 2009 - 1:17 AM - by MGunetileke
|
Hey y'all...
I've been wondering whether it is possible to replicate the awesome transition animations the iPhone has on its iPod app (when you turn the phone on landscape ). This is the one which shows the album cover art and has a smooth view arrangement that allows you to flip through the songs in a really cool way.
Implementing this (or anything similar) from scratch seems like a massive task.. Any idea if there is perhaps a library / sample code which shows how this kind of animation system built up?
Just to clarify, I am familiar with the normal flip animations and CG Animation types.. just wondering how we can setup something of this nature..
Thanks!!
