Hi,
I think the question was asked and answered but I cannot see a clearance
what is the right way to write init in the cases the arguments are nil or
wrong?
Returning a nil or raising an exception?
- (id) initWithURL: (NSURL *) url {
if ((self = [super init])) {
if (!url) {
// ?
}
if (![

If the argument values are literally wrong

The general rule is:
1. If it is considered a programming error, raise an exception (or assert -- it
is the same)
2. If it is normal code flow, then don't log or do anything strange.
However, in general, it is troublesome to have init's return nil.

No, there is an aler
Hi,
If it's a real error, this is what I do:
- (id) initWithURL: (NSURL *) url
{
self = [super init];
if (self == nil)
return nil;
if (url == nil)
{
[self release];
return nil;
}
return self;
}
or in this case, you could just do this:
- (id) initWithUR

Just to be sure what you mean: What is a real error? Simply an error
which is not a programmer's (or programming?) error?

A runtime error, one that could occur in a valid program. What this means
exactly is up to the designer of the API.

Hi all,
My Mac app currently has 3 versions of my xcdatamodel. I have explicit
.xcmappingmodels for 1->3 and 2->3 (they pre-date lightweight migration).
I now need to create version 4. Let's assume it's a trivial change from 3.
Thus, I hope to do 3->4 with lightweight migration. In fact, cu
This should "just work", of course that depends on the project. Please file a
bug and attach the project you're seeing this with.

This is odd. I have an app that downloads locations from a web service, and
creates NSManagedObejct (subclass: Location) for them. It's been working fine
on simulator and device. Suddenly, I get a consistent EXC_BAD_ACCESS on device
and simulator every time I create a new location (existing loca
Good people,
How do I go about fielding a mouseDown event in an NSTextField?

Small bit if knowledge to share. The stroke of the border is drawn centred over
the line of the border. So your described 4pt line would intrude 2pts into the
bounded area. I'm know if that will help any with understanding the
left-shifting you have observed.

For what purpose? NSTextField generally works without you having to do anything
special. If you have some unusual requirement, you'll need to tell us what it
