Cocoa Is My Girlfriend

Announcing PhotoGrab for iPad! I wrote this little utility app that allows you to browse your iPhoto library shares across your wifi network and download and save either a hi-res version of your photos or a version resized especially for display on iPad. It features multi-download as well as a slideshow mode. Just share your photos from within your iPhoto preferences sharing tab and you will be able to access your photos across the network from your iPad.

I wrote the app because I don’t sync my iPad with the computer where we store all of our photos, but from time to time I like to grab a photo from the iPhoto library without having to sync.

I just submitted a new point release that fixes a few crashers and other bugs to the App Store, but go ahead and take a look at this one and let me know what you think.

Free Promo Codes!

Just for the readers of this site! If you’re interested in the app, send an email to promocodes at cimgf dot com with the subject line PhotoGrab Promo Codes. I will send an email containing a promo code to the first 50 I receive (since the Apple only issues 50 of them per version). Be patient with me as I will be responding manually as I receive the messages. It will be first come, first served. Otherwise, check it out in the App Store. Promo codes are only valid in the US App Store.

Update on Promo Codes

I have received a lot of email requests for promo codes and will be sending them to the first 50 by the end of the day today (06/23/2010). If you do not receive a code by the end of the day, you were not in the first batch. When the next release hits the App Store, I will have another 50 at my disposal and will send those to the next group. Thanks for your interest.

In your iPhone/iPad apps you often need to know how many times your user tapped in a view. This can be challenging because, though the user may have tapped twice, you will receive the event and it will look like they tapped once as well as twice. If the user triple-tapped, you will get the event for one tap, two taps, and three taps. It can get a little frustrating, but the trick is timing. You simply have to wait a period of time to see if another tap comes. If it does, you cancel the action spawned by the first tap. If it doesn’t you allow the action to run. There’s a few little nuances to getting it to work, but it can be done. Here is how. Read more

The default implementation of the UISplitViewController based template in Xcode does not provide a navigation controller stack in the detail view. Instead it is just a regular old view with a navigation bar at the top. I suppose there are cases when you might want such an implementation, however, i think you would more commonly want there to be a navigation stack for cases when you wan to push new view controllers for your users to see. In this post i intend to demonstrate how to convert the default template to something more useable. Read more

An interesting question came up on Stackoverflow today so I decided to expound upon it in a short blog post.

A situation that I believe we are going to be seeing more and more often is one where application developers are writing multiple “versions” of their applications to be used on the desktop, their iPhone and now the iPad.

Because of that situation, it is becoming even more important that we write as much portable code as possible. Fortunately, our model can be completely portable between the two platforms.

I had to post a link to this one as well as Fraser does such a great job explaining why the iPad is so compelling . From Fraser’s post:

The tech industry will be in paroxysms of future shock for some time to come. Many will cling to their January-26th notions of what it takes to get “real work” done; cling to the idea that the computer-based part of it is the “real work.”

It’s not. The Real Work is not formatting the margins, installing the printer driver, uploading the document, finishing the PowerPoint slides, running the software update or reinstalling the OS.

The Real Work is teaching the child, healing the patient, selling the house, logging the road defects, fixing the car at the roadside, capturing the table’s order, designing the house and organizing the party.

Exactly! The iPad is genius and it will revolutionize not just books, magazines, etc., but it will revolutionize computing as we know it. I don’t know about you, but I’ve got the new SDK fired up and ready to start rocking some apps and it is a very exciting new platform!
