I recently upgraded my primary development system to Lion and
I'm encountering a phenomenon with a lot of different
applications (not just my own) where the app will hang for 20
seconds or more when it's first launched or a document it opened.
sample shows this on the main thread:

Ah, I missed the disclosure triangle. Unfortunately, unchecking that file
didn't seem to stop the converter from checking it. I needed to do a Clean
first.
Just 11 issues to go
Thanks!

Hi,
Step A:
In your delegate for AVCaptureVideoDataOutput, you can use the method
- (void)captureOutput:(AVCaptureOutput *)captureOutput
didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer
fromConnection:(AVCaptureConnection *)connection
to grab CMSampleBufferRef representing each frame. Y

Hi,
this might be totally trivial, but all suggestions I found in the docu and on
the web failed. I don't want my detail view to show any kind of back button. So
from the documentation I came up with the following possibilities:
1. set leftItemsSupplementBackButton to NO
2. set leftBarButtonIte
Thanks, this works.

This sounds like Lion auto saving. Are you on Lion? If so, do you return YES

You're trying to parse a Canadian-format string, but initializing the formatter

The property declaration makes available calls [self textField] and [self
