I would recommend breaking out the frames of that gif and use animatedImageNamed:duration: – you can name them all the similar name with a number change at the end. For instance: loading-1.png loading-2.png loading-3.png etc. Xcode will recognize you want multiple images and will play those through in order. Look at THIS
TL;DR Your best bets are usually a for-of loop (ES2015+ only; spec | MDN) – simple and async-friendly forEach (ES5+ only; spec | MDN) (or its relatives some and such) – not async-friendly (but see details) a simple old-fashioned for loop – async-friendly (rarely) for-in with safeguards – async-friendly Some quick “don’t”s: Don’t use for-in … Read more

Yes, it was added in version 2.5. The expression syntax is: First condition is evaluated, then exactly one of either a or b is evaluated and returned based on the Boolean value of condition. If condition evaluates to True, then a is evaluated and returned but b is ignored, or else when b is evaluated … Read more
Executive Summary Note that in most cases the remote name is origin. In such a case you’ll have to use the command like so. Delete Local Branch To delete the local branch use one of the following: Note: The -d option is an alias for –delete, which only deletes the branch if it has already … Read more
Dependency Injection is passing dependency to other objects or framework( dependency injector). Dependency injection makes testing easier. The injection can be done through constructor. SomeClass() has its constructor as following: Problem: If myObject involves complex tasks such as disk access or network access, it is hard to do unit test on SomeClass(). Programmers have to … Read more
If you don’t have permission to the file (e.g. you don’t own the file), then it will not force the write. If you do have permission to the file, but it is a read-only file, then you can force-write it. It’s as if you first change the file mode to writable, write your changes, and … Read more
It’s done so that addition doesn’t need to have any special logic for dealing with negative numbers. Check out the article on Wikipedia. Say you have two numbers, 2 and -1. In your “intuitive” way of representing numbers, they would be 0010 and 1001, respectively (I’m sticking to 4 bits for size). In the two’s … Read more

Two’s complement is a clever way of storing integers so that common math problems are very simple to implement. To understand, you have to think of the numbers in binary. It basically says, for zero, use all 0’s. for positive integers, start counting up, with a maximum of 2(number of bits – 1)-1. for negative … Read more
