Alerts form the backbone of many user interactions. While there have been changes to alerts over the years, very little has changed about their appearance or our ability to customise that appearance leading to many tear-filled designer outbursts 😱. Here, we look at how to ease that pain.

Being British, queuing is essential to me. I take every opportunity I can get to queue. However, UIAlertController doesn't care about queuing 😞. Here, we look at how to introduce UIAlertController to the joys of queuing and ensure that each alert gets its chance to shine.

In the fairytale 🧚 version of UICollectionView, a cell has a simple view inside it. In the nightmarish reality, a cell sometimes needs to host a UIViewController. Here, we look at how to stuff a UIViewController instance inside a UICollectionViewCell, avoiding various gotchas.

Modals are often used as one-way gates, e.g., preventing a user returning to the registration screens after registering. However, this misuse of modals leads to bugs when the user inevitably jumps the gate. Here, we look at how to build proper one-way gates by tweaking the navigation stack.

Hollywood loves ghost-typing animation 👻, but it is surprisingly tricky to get right. Here, we look at how to create the perfect ghost-typing animation that will wow your users.

The other day I was developing a dictionary view controller that consisted of a UITableView and an NSArray (approx. 4000 elements) holding the data to be shown. As the elements were of varying lengths I had implemented the delegate method: - (CGFloat)tableView:(UITableView *)tableViewheightForRowA

I ran across the scenario where I wanted to disable the paste functionality on some textfield in my application. I've did this many times before and quickly added the following method to my viewcontroller: -(BOOL)canPerformAction:(SEL)action withSender:(id)sender { if ([UIMenuController s

I found it surprisingly tricky to track down how to hide the tabbar on certain view controllers without ending up with a white area where the tabbar would have been. What you need to do is set the tabbar hidden property on the UIViewController you are about to push rather than on the UITabbarControl

I ran into this problem were I could not get a bundle image to appear in a UIWebView. It turns out that in order to enable this functionality you need to tell the webview where to look for these images, in the below example we tell it to use the main bundle: NSString *bundlePath = [[NSBundle mainB

A common scenario in iOS development is to create a textfield that will only allow a certain number of characters to be entered. We can implement this constraint by: - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { BO

When I wanted to add a Done/Next key to the keyboard I found it surprisingly hard to find out how this was possible. After much research I stumbled upon the solutions that you go through the textfield to set the button. Done - (void)textFieldDidBeginEditing:(UITextField *)textField { text

Recently I was asked to add a pale (off-white) color as the background color of a navigation bar, which I thought would just be a case of updating the tintColor property . However when I did this instead of getting the gradient effect that we were after all I ended up with was a solid off-white colo

Working in a team, I often find myself trying to avoid using Interface Builder (IB) as much as possible. This is because trying to resolve the inevitable conflicts that arise when two developers change the same xib can be soul-destroying ⚰️. A sea of seemingly unrelated xml changes awaits anyone who

I use the below category when working with dynamic content. It has useful methods for setting up a UILabel frame based upon its content and restrictions that you place on it. .h @interface UILabel(Size) /* @method Adjusts UILabel's frame to begin at defined x and y position and have a dynam
