Xcode6 simulator path, xcode6 simulator pathAfter the release of Xcode6, there have been many changes and functional changes. I will not repeat them too much here. On WWDC, Apple has already talked about it and there are many articles on the Internet, here we will introduce some small things that are not easy to find, but very important.1. Xcode6 simulator path c

The Android system only accesses the PC by default via IP (10.0.2.2), and the PC does not have direct access to the Android emulator system via IP. To achieve communication between PC and Android simulator system and Android Simulator, it is necessary to use port redirection (redir).Let's talk about the Telnet client installation required for Port redirection:Windows:Install the Telnet client. If it is not

ObjectiveThe small partners who have done the app test on iOS should know that the normal user installs the app from the AppStore, installs the test version of the app, is usually developed to the QR Code Scan code installation,or develop an. IPA installation package file, which is installed through itools. It's not that easy to install app testing on an iOS simulator for a small partner who doesn't have an iphone real-world device.First, start iOS Si

This is a study of C #, WinForm's self-review process, to find the shortcomings of the existence, but also to promote their continued learning.University communication major After graduation, entered a power technology company engaged in software development work, mainly used in Delphi language for power Communication protocol host computer development. Because the host computer needs to communicate with the next computer to test, and in fact there are not so many ready-made devices for you to b

The CRC is calculated using only 8 data bits, starting bit and stop bit, if parity bit also includes parity bit , do not participate in CRC calculation.The CRC is calculated by:1. Load a 16-bit register with a value of 0XFFFF, which is the CRC register.2, the first 8-bit binary data (that is, the first byte of the communication information frame) and the 16-bit CRC register is different or, the result is still stored in the CRC register.3, the CRC register the contents of the right one bit, with

Later in the development of iOS programs, you need to package and distribute the program to everyone for testing. In general, this type of test is a real-machine test, which is correct and necessary. There is just one problem that the IPA package that generates the real machine test requires the relevant certificate.Of course, the vast majority of iOS developers and even some independent developers can easily (fair bet) get these certificates. Therefore, it is necessary to declare the applicable
