Welcome to the list and the platform, JD. The purpose of the cell reuse queue
is so that we don't have to keep creating new cell objects as we scroll a
table. We take advantage of the fact that as new cells are appearing, old cells
are disappearing. Rather than throw the old cells away and creat

Agreed; I've added such "value accessors" with no trouble.

Hi there!
I am planning to implement a component similar to the iphone's photo album.. I
guess that using uviews will make the component to have a bad performace , I
mean scrolling slow and all of the stuff ... so which way should I take? Is
CALayer better than UIViews in terms of performance?

During the recent text orientation/position thread a couple of things caught my
attention: (1) the text system seemed designed to have a flipped view (origin
in the upper left), and (2) the iOS version of an NSView, the UIView, also has
an origin in the upper left.

You didn't call -shouldChangeTextInRange:replacementString: first, or
call -didChangeText when you were done.

Hi all,
I've got an intermittent crash which occurs when adding an NSString to an
NSTextView in my app's main window. I very rarely experience the crash myself,
but a relatively high number of users have reported it to me.
It finally happened to me while running the app from Xcode tonight, so
Lorenzo:
By deleting "setDateStyle", the following provided the result I believe you
hoped for:
NSDate *now = [[NSDate alloc] init];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"EEE_MMM_dd_"];
NSString *filenameDate = [dateFormatter
Thanks everyone! I've learned a lot. I also found working in a flipped view
easier for just getting a grasp of things like the NSRect returned by
-usedRectForTextContainer:.
Just for fun, I played with an NSView that is flipped, *except* just before the
call to -drawGlyphsForGlyphRange:atPoint

Well, being the OCD type :-) I really wanted to make this work to prove I

The first thing I ran into was I had a property called "lineSpacing". I

Again, if you have previously paired the device, I think you can get some form
of notification, especially if your app is already running.
But if the device was never paired, the user would have to explicitly pair them
first. It's a security issue.
I don't know even that another device running

Hi,
mm.. ok. So that would mean even applying for MFi cannot notify that a new

Hi,
Thanks. So it would be searched by iPhone it self.
I found another confusing article on web.

Once you build a compliant device, you can communicate with it in any way you
want.
But as I said in the last email, you have to first pair it, using the Settings
app, and establish a connection between the iPhone and the hardware device.
Once you have that connection established, then the hand
Hi,
Let's say if we build a Hardware Device that is MFI- complient by getting
Apple approval for hardware. Would that mean our iPhone application can
search for that hardware with External Accessory Framework ? and find it's
name.. ??
Thanks a lot for your info. :)

Nope. The MFi-compliant device must first establish a Bluetooth RFCOMM
connection to the phone (which means it needs to be paired). Then the MFi
authorization happens over that RFCOMM channel, and once that's complete, only
then does the device show up in the External Accessory framework.

Hi,
Actually, I found this link.
http://developer.apple.com/library/ios/#qa/qa2009/qa1657.html
Does it mean that iPhone could search for MFI hardware and get its name
using External Accessory Framework. Could someone confirm on this ?
Thanks,
