So when Mavericks came out, Messages synced across my iOS devices and OS X/MacBook. Then it stopped. I long waited for the day when Yosemite and iOS 8 would come out and fix it all. No dice. I couldn’t even send to other Messages users. With iOS 8 and Yosemite I could now send texts to Read more about Messages Not Syncing in Yosemite OSX MacBookPro – FIX![…]

Using the MKMapCamera, you can set the orientation of a map without messing with transforms on the view or even detecting the user’s heading (though that could be helpful too).

MKMapCamera *mapCamera = [[self.mvMap camera] copy]; [mapCamera setHeading:headingDegrees]; [self.mvMap setCamera:mapCamera animated:YES]; |
If you don’t want the animation, you can just set the new heading on the existing camera:

In some cases, you want to disable ARC in your project just for one or some subset of files.

My Laravel app wasn’t retaining the session from one page to another. The session files were created in app/storage/session, but clearly weren’t used.

Sometimes it’s necessary to change the font on an app and you don’t want to go into Interface Builder and manually change them all. Ug. So you can recursively call a method to change the font on all subviews that respond to the setFont: method.

Sometimes I can’t help but notice how much blue Apple tends to use in their icons. Both OSX and iOS. I wonder if it’s b/c they have a preference for that color for some reason or if it’s more for flow and appearance??? Some other icons are designs (maps) or another color (iTunesConnect) and such, Read more about Apple Loves Blue???[…]
In one project, I needed to present some one-off view controllers so I thought it would be best to put them in their own StoryBoard file and load them in code. I wrote a method that takes the view controller name (set in the Identity Inspector – see image). In this case it is “browserVC” Read more about Loading iOS ViewController in Code from a Storyboard File[…]
Similar to the post about reverse geocoding, the forward geocoded uses CLGeocoder. I wrote a quick static method that takes an address string (e.g., “4700 Louisiana 22 #1, Mandeville, LA 70471”) and a completion handler. All this method does is create the CLGeocoder for you and make the call. It’s mostly just a way to Read more about Forward Geocode in iOS with CLGeocoder[…]
If you’re using CLLocationManager to obtain the user’s location, you can add some code in the delegate method to reverse geocode the user’s location…

I had a unique problem today – if a page opens a new ‘window’ in a UIWebView and then calls window.close to close it, how is that handled in iOS? UPDATE: Swift version added at the bottom.

Apple – iPhone 5s – Tips and Tricks. Many people have been confused by the changes in iOS 7. Apple has published a list of Tips and Tricks. It’s geared towards iPhone 5S so it may not all apply to iOS 7, but there are other pages for: 4s and 5c.
I found my popover’s going to iOS 7 didn’t look so great. I searched around and posts were pointing to subclassing the abstract UIPopoverBackgroundView class. I found GIKPopoverBackgroundView and the demo app for it looked good. It was fairly easy to use – Copy GIKPopoverBackgroundView.h/.m into my project Copy the images from the images folder Read more about UIPopoverBackgroundView[…]
