I keep forgetting how to do this… don’t ask me why, it’s not that difficult! So here’s how we define one: – (void)methodName:(NSString *)parameterOne methodNameContinues:(NSString *)parameterTwo; Add more parameters as you please. In theory, the method name is split across these multiple descriptive parts before each parameter is defined. However in reality I find it […]
On the iOS simulator we have the luxury of peeking inside our virtual devices with the Finder. We can do this by heading over to the Finder, holding down Option and clicking Go. This will bring up the Library, in which you can navigate to Application Support / iPhone Simulator / 7.0 / Applications / […]
If you’re displaying images from the main iOS bundle, things are fairly straightforward: self.imageView.image = [UIImage imageNamed:@”Amy.png”]; But if you have an NSURL to your image then it’s not as easy. It took me some digging to find out that you have to convert the URL into NSData first, and then display the data: NSData […]
You can do this either by using paths or NSURLs. Apple recommends using NSURLs, so here’s how it works. In this example we’re copying a file called “Amy.png” which exists in the app’s main bundle. // file URL in our bundle NSURL *fileFromBundle = [[NSBundle mainBundle]URLForResource:@”Amy” withExtension:@”png”]; // Destination URL NSURL *destinationURL = [[self applicationDocumentsDirectory]URLByAppendingPathComponent:@”Amy.png”]; […]
Sometimes it can be useful to split your Core Data Store File across multiple files. For example, one file could live on the local file system, while the other could live in iCloud. We can do this by telling the Xcode Model Editor to add more than one Configuration, each of which can be allocated […]
I’ve been recently using Tumblr more to post sketches from all kinds of devices, and naturally I wanted to embed them in some of my websites’ sidebars.
I found the extremely helpful Tumblr Widget plugin by Gabriel Roth for this: install, drag in the widget add Tumblr URL. Done!
I wanted my images to be in a size that the widget didn’t offer, so I did some tweaking – perhaps it’ll help if you’re in a similar situation.
Sometimes things don’t work out with replication. When I first started experimenting with it I thought this was a “setup and forget about it” kind of job.
Experience has shown though that you have to regularly triple check and see if things may have broken (despite a good and once working setup).
Let’s take a look at what you can do when your Slave isn’t replicating anymore. If you want to know more about how to setup replication, have a look at my previous article in which I explain how this works.
This is a step-by-step guide on how to replicate an existing MySQL server. The server is live and contains data and needs a constant backup companion.
Many tutorials focus on how to setup replication when no data is present on the system. That’s an ideal solution if you’re building a new setup, but in case you’ve got a server that already has data present then here’s how to accomplish the this:
I’ve done this several times and always forgot to take some notes – until today. Without further ado, let’s replicate MySQL.
