I needed an application that could create a PDF out of a webpage. I found a few apps on the AppStore, but none of them met my needs. I figured it would be a fun project and created WebPDF.
It’s a simple application that creates PDF’s out of webpages. The app saves the PDF, lets you view it and export it. It’s optimized for all iPhones (including the iPhone 6 and iPhone 6+) and the iPad.

I previous wrote about how much I liked the Serfas Thunderbolt USB Taillight. Well now I have even more reason to like it. A couple of weeks ago, a plastic piece inside the USB connector broke off. This is the same plastic piece you see on all female mini USB connectors. I think this is bad design on USB’s part, not Serfas. I assume it broke because of the almost daily plugging in to be recharged.
I was about to order a new one, but decided to check out their warranty page: Serfas Warranty I emailed their warranty email address about my problem and got a response within 30 minutes. They said to mail it in and they would fix or replace it.
I mailed it in and about a week later I got a package at my door with a brand new Taillight. This is an awesome product from a company who stands behind their product. I highly recommend it. You can buy the Serfas Thunderbolt on Amazon I’ve already bought one for my kids.
Comments closedPrior to Xcode 6, all new projects contained a prefix header. In Xcode 6 a prefix header is no longer included in the default project. Instead of using a prefix header you should put your imports in the files that need them. But in the case that you need one, you can still add one.
From the menu, select File > New > File…
Choose iOS > Other > PCH File
In the Build Settings, each for “prefix” to narrow down your choices. Under “Apple LLVM 6.0 – Language” find “Prefix Header”. Add “$(SRCROOT)/PrefixHeader.pch”. Make sure the path is correct. When you close the dialog, it shows the expanded path.

After updating to Xcode 6, I thought Apple removed the ability to create a category when creating a new file. I was wrong. They just moved it.
To create a category in Xcode 6, choose File > New > File
Then select iOS > Source > Objective-C File
Choose File Type: Category. Then enter you File name and the class you want to create a category for.

Comments closedHere’s how to get at the main storyboard from inside your view controller.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:
[[NSBundle mainBundle].infoDictionary objectForKey:@"UIMainStoryboardFile"]
bundle:[NSBundle mainBundle]];
Most of the time you can just use self.storyboard. But if you are in a view controller that was not created by a storyboard, then self.storyboard will be nil.
Comments closedI’ve gotten this message “Unable to determine simulator device to boot.” a few times when trying to run my app in the iOS Simulator. 
Each time it took me awhile to remember what it meant.
I’ve been working on updating an app to iOS8 and using Xcode 6. Occasionally I need to run the current version and I start up Xcode 5. When trying to run the app in the simulator I see this error.
The reason for the error is because the Xcode 6 simulator is already running and it doesn’t know which one to use. 
The solution is simple. Just quit both simulators and try again run again.

As an iOS developer, here are a few things I’d like to see at WWDC 2014
- Siri Extensibility – I’d like to see Apple open up Siri to third party apps. For example if I have RunKeeper on my iPhone, I’d like to be able to tell Siri “Start my run”, “End my run”.
- Blocks added to older API’s – A lot of older API’s are using delegates instead of completion blocks. For example: UIAlertView
- UIActivityViewController enhancements – Every time I’ve used UIActivityViewController, I’ve had to extend it to do what I wanted. It shouldn’t be that hard to share an email where you can specific the recipient, subject, attachment, body, etc..
- Inter App Communication – I’d like to see something more like Intents on Android.
- AppleTV SDK – I’d love to be able to write apps for the AppleTV
- Filesystem – Mac OS X and iOS are due for a new filesystem. ZFS was rumored for awhile but fell through.
- Multi User iOS – It would be nice if iOS support multiple users, so a family could share an iPad.
I’ve had this error a few times, so I figured I’d document the solution for the next time it occurred.
When doing a build in Xcode, I got the following error:
ld: library not found for -lPods
My project is setup to use cocoapods.
First make sure you are using MyProject.xcworkspace and not MyProject.xcodeproj
For me this was the case. But I realized that I just created a new configuration for “Ad Hoc” builds. To fix the problem I had to install the Podfile again with the command:
pod install
After running pod infall, open the project: MyProject.xcworkspace, clean your project and build. The error should go away.
