i want to create a pdf with a clear (transparent) background, but cannot.
The pdf is created, looks ok, but has a white background.
What am I missing?
Here the code:
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
NSRect rect = NSMakeRect(0,0,99,99);

Are you sure? How are you viewing it? In Preview, you get a white background
unless you check "Show Image Background" in the View menu.

Thanks for the pointers. I also just found this sample code from Apple:
,http://developer.apple.com/library/mac/#samplecode/SidebarDemo/>
They don't use CoreData but I may be able to adapt it.

Instead of the the links you would use to the left of the actual documentation,
you now use the breadcrumb links towards the top of the documentation. It took
me a while to get accustomed to it, but in the end you have more room for your
documentation text.

I have a nib based toolbar in a window.
I have set the customise toolbar flag to YES (in IB and programmatically).
I have set the View menu items 'Customise Toolbar...' and 'Hide/Show

This is how I solved it. I my OutlineViewController, I created an array with

And then create the entities for these names:

I am trying to convert a Core Data app which uses garbage collection to ARC.
When I run the refactoring tool, I see issues like:
Semantic Issue: Type of property 'person' does not match type of accessor
'setPerson:'
The relevant declaration code:
@class ABPerson;
@interface XG2Student : NS
Hi,
I am planning to redesign my existing app. I want to use the storyboard for
UI development and it should support the older OS starting from 3.2.
I guess storyboard is Xcode 4.2 feature, it should not be any problem to
support for older OS.
Anyway I want to conform with you before I star
Storyboard is an iOS 5 feature. It will not work on older OS versions.

Despite reading the ARC documentation about 5 times, scanning the devforums and
reading Mike Ash's post about ARC I'm totally failing to find the correct
bridge cast for the following piece of code when converting to ARC.
-(void)addView:(UIView *)view forElement:(id)element

I am converting a project to Arc.
Formerly I had:
CFStringEncoding encoding = ...
CFStringRef axa = CFStringGetNameOfEncoding ( encoding );
NSString *encodingName = (NSString *)axa;
NSDictionary *d = [ [ NSDictionary alloc ] initWithObjectsAndKeys:
encodingName, kEncodingN
Yup. Wish Xcode could convert down somehow when targeting lower because
storyboards are super awesome.
