Often when you're searching the web for some particular bit of information, your search pulls up a long page of text. But you then have no idea where on that page to find the information you're looking for. The next step is to search within the page. The way to do that on iOS devices is simple, but not obvious.
In previous posts I have touched on inheritance in Swift. In this post, I'm going to be diving deeper and giving you a fuller picture of how inheritance works in Swift, and how you can use it to create apps that are easy to extend when you need to add new functionality. Along the way, you will also learn about the important concept of polymorphism and learn how to use Xcode's new playgrounds!
One of the useful features of email is being able to see exactly when an email was sent. However, unlike Mail, the default view in Messages doesn't show the time when messages in a thread were sent. Messages are time-stamped just as emails are—you simply need to know how to view the time stamp.
One of the great new features in iOS 8 is the ability to send an audio message. Sometimes it's simply a lot more convenient to make a quick recording than it is to type a message. Why not simply call the person? Because convention requires that we then engage in conversation. An audio message is more efficient. And the party you're sending it to can listen at his or her convenience rather than having to answer the phone.
One of the great features of our mobile devices is the ease with which we can share photos and videos. You can use your iPhone or iPad to send multiple photos via email or messaging. Note that there's a limit of five photos via email, but not via messaging.
You may have had the experience of working on a draft of an email but then needing to look at a different email in your inbox. But the draft obscured the screen and couldn't be quickly be pushed aside and then returned to. Fortunately, Mail in iOS 8 has remedied this situation. You can swipe away a draft, access your other email, and then quickly bring it back into view to continue working on it. This is typically referred to as "minimizing" the email draft.
One of the useful new features of iOS 8 is the ability to view the desktop version of a website in Safari rather than the mobile version — saving me a lot of frustration. For years I’ve had a personalized Yahoo page that's well organized into three columns: 1) stocks, sports, weather, 2) top news, science news, Doonesbury, and 3) Apple news sites. So it was really disorienting when I would go to my Yahoo page on my iPad and all the news feeds would be in two columns with the order all jumbled up. The first time I used this new iOS 8 feature to request the desktop site, my response was: hallelujah!
If you have read Apple's documentation on Generics and were left wondering how you could use this technology in your own projects, this post is for you! You will learn how to take full advantage of generics in your every-day code as well as how to avoid the constant type-casting that usually results from creating generalized code.
Mail in iOS 8 has a lot of helpful features that make it easier for you to deal with the onslaught of email messages. In addition to the new swipe gestures covered in a previous tip, iOS 8 also offers a quick way to mark all email messages as read. If you've glanced down the list of messages in your Inbox and determined there's nothing needing your attention, this is a quick way to deal with them.
If you're like me, you spend a lot of time each day dealing with email. The new swiping gestures available for marking and flagging email messages in iOS 8 can save you some of that time. An earlier tip by Sarah Kingsbury explained how to swipe left to quickly delete messages. But you can also use swiping gestures to mark emails as read or unread or to flag them for followup, as well as every other function, such as forwarding or moving to another folder.
Have you always wanted to build an iOS app, but lacked the knowledge and skills? Have you ever signed up for an online course on creating iOS apps, only to feel frustrated because the content was out of date or not comprehensive enough? Are you dying to learn more about Swift and programming for the Apple Watch? It's a story we hear all the time at iPhone Life. And that's why we decided to partner with iPhone app expert, former Apple employee, and adjunct professor at RIT Paul Solt to make his iOS development courses available to iPhone Life readers at a big discount.
iOS 8 finally brought the ability to customize the iPhone and iPad interface by allowing you to add widgets to the Today screen in Notification Center. In an earlier post, I explained the simple steps for doing this. You simply swipe down from the top of the display to view the Notification Center and tap on the Edit button at the very bottom. This reveals widgets that are associated with apps that you already have installed on your device. You simply tap on the green button to add a widget.
Vidget (free) is different. Instead of being an app such as ESPN Sport Center with an associated widget, its sole function is to let you easily add a bunch of widgets to your Today screen, with about 20 different widgets currently available.
While each new version of iOS introduces plenty of new features, sometimes Apple just changes the way things are done, often without any explanation. One such example is Private Browsing. Previously, there was a Privacy button at the bottom of Safari, when viewing an index of favorites. With iOS 8, that's gone.
If you like to use the camera on your iPhone or iPad, one of the features you'll appreciate in iOS 8 is the ability to recover deleted photos. When you delete a photo, it remains available in the Recently Deleted album on your device for 30 days. If you decide that in fact you want to save a photo you deleted, you can easily recover it.
If you're concerned about battery life, you'll want to check out the new feature in iOS 8 that lets you see what apps are using your battery the most. This usage can simply result from your using an app a lot, but other times apps have background processes that drain the battery or the app isn't working properly. This feature gives you a clearer picture of what's going on.
I constantly use tabs in Safari. When I'm viewing a page and see a link I want to read — but without closing the page I'm currently on — I tap and hold the link to open it in a new tab. I sometimes have as many as a half dozen tabs open. And nothing is more frustrating than inadvertently closing a tab when it's something I haven't yet read. Fortunately, if that happens to you, there's a simple way to re-open recently closed tabs.
Access Control is one of the late-breaking features added to the Swift language. It allows you to specify the parts of your code you want to make public, and the parts you want to hide. It's an important tool in creating easy-to-use, and easy-to-understand interfaces.
You've probably had the experience of listening to the radio and wondering the name of the song that's playing—maybe it's new to you and you're wondering who the artist is, or maybe it's familiar but you can't remember the name. Now with iOS 8, Siri can help. In the past, you could ask Siri to identify music playing on your device, but with iOS 8 you can ask Siri to identify any ambient music. And, conveniently, Siri also makes it easy to purchase the song or album.
Can Apple read your mind? With iOS 8, it looks like it! Apple has caught up with Android and other platforms that offer a form of predictive Text called QuickType. This means, when composing text, your iOS device will suggest words that it thinks you want to use. While AutoCorrect guessed at a word, based on the letters you type, QuickType predicts what word you might type next based on the context of your message or document.
Among the many new features of iOS 8 is grayscale mode. Why would you want your display to appear gray rather than in colors? There are two main reasons. First, for those who are color blind, items such as menus may be hard to distinguish if they rely on color to stand out from a background. Grayscale can make the display more readable for them. And second, if your battery is running low and you know that it will be a while before you'll have the opportunity to charge it, grayscale can extend battery life.
