You must be worried . The path changes after

6 months 3 days One o'clock in the morning, Apple held the annual Global developer conference in San Francisco, USA . Published by the highlights of IOS 8 can roughly be summed up into these:1, the information can be added to voice picture text, similar;2.Open third-party input method to support intelligent input prediction;3 , the top of the notification bar d

The Android platform is still better than the top ten features of iOS 8 (1) BKJIA may be surrounded by a bunch of friends who are still waiting to buy the brand new iPhone 6 or 6 Plus devices, but they are standing in front of the Apple store in the heat of the sun and the storm, we stayed in our comfortable room and customized our Android devices as needed. Th

This series of tutorials is guided by iOS8 and the latest swift, and all the examples in the video are debugged in the latest Xcode. Theoretically, all examples can be successfully run on the Iphone/ipad simulator. Note, however, that some demos, such as GPS, gesture recognition, and so on, are recommended for testing on real devices. This roadmap provides a video course that is the most in-depth, full-web. Through the study of the road map, students

Book Description “About a year ago, noticing that Apple had not updated Objective-C much over the past few years, I got intimations that they were working on a new language or framework for iOS development, and even suggested it to my friends at work. They laughed and said, “Then you will have to write your book from scratch.” They were right; this edition is almost a whole new book”Excerpt From: Vandad Na

Convention). If you go deep into the source and find that this property actually returns a Nsmutablearray, and then skips the API to use it directly, it will break the Convention, which is not a problem for the Class designer.Another problem is if you use this property inside a class. It is generally recommended that you also use property access within the class, rather than directly accessing the underlying instance variable (note: This may differ from the effective objective-c, however, accor

The default language for iOS 8 is changed. [Problem] The test group found that when the APP is on iOS 8 or a later system device and the language is set to a small language that we do not support, the APP did not use the default English, but chose the last language. [Analysis] After research, we found that the "pre

parsing operations (especially complex parsing) are performed asynchronously with pre-execution, and the parse results are cached. Can pre-load the required network resources (pictures, etc.), Sdwebimageprefetcher. There is performance implications to using instead of the property tableView:heightForRowAtIndexPath: rowHeight . Every time a table view is displayed, it calls on the tableView:heightForRowAtIndexPath: delegate for each of its rows, which can result in a Significa

How to use Swift to implement Touch ID verification in iOS 8? IOS8 opens many APIs, including HomeKit and HealthKit. Here we want to talk about Touch ID verification for one of them. In the past, apps were used to protect users' private content. Only passwords can be set and entered. The iPhone can only use Touch ID to easily unlock its own apps. It's really urgent. Now we can also be cool. When you open a
