A few days ago, Stanford Engineering College launched a free online iOS Application Development Course (CS193P), which focuses on iOS 5 Application Development and is divided into 11 parts, each part consists of a video and a slide. This course is provided through "iCloud, video stream push, and wireless synchronization. To learn this course, you need to know ab

The IPA file is normally output from Xcode's organizer, but we do not have a certificate so the output generates an error. We can only do this with a little trick.

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 can fully grasp the iOS8 development process,
