In this podcast I will show you how to use the MORE and NEXTPAGE features in WordPress. These are built-in tags that will make your posts look their best: MORE can break your post off on the front page, so instead of the entire post being displayed you can choose where WordPress inserts a “read … Read more
We can do this two ways: // version 1: [self.searchBar becomeFirstResponder]; // version 2: [self.searchDisplayController setActive:YES animated:YES]; The benefit of version 2 is that if we perform it “in vision”, we can use the animated option and make it look all swish. Version 2 of course also has a reverse with which we can deactivate […]
We can use substringWithRange for this, which requires us to define a range: NSString *something = @”123456789″; NSRange myRange = NSMakeRange(2, 3); something = [something substringWithRange:myRange]; // something is now 345 You create a range by specifying where the substring should start (the first character is 0, like in an array), then specify how many […]
We can use the substringToIndex method for this, using the length of our original string minus 1: NSString *something = @”12345″; something = [something substringToIndex:(something.length – 1)]; // something is now 1234
With typedef you can specify custom variable types. Instead of having a variable such as int, you could create your own – such as yourInt: // create a typedef of int typedef int yourInt; yourInt yourValue = 57; NSLog(@”Your value is %i”, yourValue); Now you have your own variable type called youInt which behaves just […]
An Enumeration (enum) allows you to create a collection of custom values. These can be more meaningful than simply using numbers. Imagine you want to track drink sizes, such as small, medium and large. You can remember to just use the numbers 1, 2 and 3 for each size – but Enumeration makes it easier […]
On occasion we need to create an NSIndexPath manually, with components we specify (such as a row or a section). There’s a method for that: indexPath:forItem:inSection. Here’s how you create an indexPath for row 0, section 0: NSIndexPath *indexPath = [[NSIndexPath alloc]init]; indexPath = [NSIndexPath indexPathForItem:0 inSection:0]; The method takes two integers. You can even […]
Imagine you had an NSDate object and want to add days several to it. We can use NSDate method dateByAddingComponents for this, which takes – as you may have guessed – NSDateComponents as parameters. In this example, let’s assume we want to know what date it is 5 days from today: int daysToAdd = 5; […]
