hello,
I spent all day getting some AR app done and used the CLLocationManager's
heading and the CMMotionManager a lot. then in the evening the compass freaked
out, not only in my app, also the built in Compass.app, which would be
sometimes correct, but most of the time between 20 an 180° degre

Hello,
I load an utf-8 textfile from a server with
[NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&err]
and non ascii characters are still not right, e.g. "ü" becomes "ÃŒ". is that a
problem on my end or on the server side?
thanks and regards,

Hello,
If you are still learning I would recommend NSImage, it's the easiest to use.
If you need many images and high framerates I would recommend to use OpenGL.
CGImage, CIImage are rarely used for special purposes.. I wouldn't bother with
them at the beginning.

Hello again,
why is it that when I set the content mode of an UIImageView to
UIViewContentModeBottomLeft I cant change it's size anymore?
this is what I do:
self.imageView.image = theImage;
self.imageView.contentMode = UIViewContentModeBottomLeft;
self.imageView.frame =

Hello,
In my project (iPad) I use a UITableViewCell subclass. The problem is, that the
built in textLabel doesn't show the text.
Here is some test code:
-(void)setText:(NSString*)text {
CGRect r;
r.origin.x = 30;
r.origin.y = 5;
r.size.width = self.bounds.size.wid
Whoops, sorry, I forgot it again, this refers to the iPhone/iPad and iOS
versions >= 3.2 which do not sem to support the basic MPMoviePlayerController
anymore.

Hello,
I need to update an older app which is based only on a window and a view. Up to
now it shows a movie using the MPMoviePlayerController. Now I have to use the
MPMoviePlayerViewController. Unfortunately since there is no view controller I
can't just call presentMoviePlayerViewControllerAni

every few times I want to step through my code with Xcode's debugger it

Hello,
I'm writing an app on iPad that lets the user navigate through a >700 page pdf.
When he's on some page I preload the next and previous pages as UIImage (using
CGContextDrawPDFPage()) so navigation is faster. Everything is fine at first,
but after a few tens of pages the memory gets full

Hello,
When I download an image and want to keep it for further reference, I assume I
have to store it in the documents directory and not in the app bundle, because
otherwise I would invalidate the signature and the app wont run anymore. Is
this correct?

Hello,
How can I find out if my first view is up and running? When viewDidAppear is
called on my fist UIViewController I'm still looking only at the Default.png.
What I do first in my app is:
1. wait for viewDidAppear to be called
2. show some wait-indicator
3. load some data from the net
4. hid
Whoopsie! Thanks a lot!

Hello,
this is the weirdest thing i saw in a while.
I load an image with
[NSImage imageNamed:@"someName.png"];
the image is has a size of (159, 256)
Every other time I start the app in the debugger the loaded image reports a
size of (23, 36.4812) and contains only garbage of some old image I
