During iOS development, the asihttprequest library is the most commonly used network library, which is powerful and easy to use. However, there are several minor issues when using this library. I have been searching and researching on the Internet for a long time. It is now recorded here.Question 1: One problem is that

I have previously written an article "using the SoundTouch library in IOS to achieve sound changes ". Finally, many of my friends posted on their blog that the code can run on the simulator and cannot run on a real machine. They have been busy some time ago, 2013 the rankings of good-looking American TV series do not have time to go through the code and check it out. Today, I checked the root cause of the p

The solution to the linker command failed with exit code 1 (use-V to see Invocation) error is to find the target --> buildIn phases --> compile sources, all. M files in the third library are added to it, and the compilation is successful; Cause: when using these third-party class library files, we drag them directly to the project, and xcode does not automatically reference them during compilation. Therefo
