ObjectiveThere is a requirement in the recent project to share entity content directly from third-party apps to our app using the content sharing features available on iOS devices from the iOS system. The general principle is this, first for our iOS app registration can open document types (file type), and then in third-party apps, if they use the sharing features provided by iOS, then you will see our app, click to share. and the specific ideas about the design and implementation of the require

The HP uniqid () function can be used to generate a unique identifier that is not duplicated, based on the current timestamp at the microsecond level. In the case of high concurrency or long intervals (such as looping code), there is a large amount of duplicate data. Even if the second parameter is used, it repeats, and the best scenario is to combine the MD5 function to generate a unique ID. PHP uniqid () generates a method that does not duplicate un

Solution: To add a using namespace STD; statement after the macro definition. Explain: The so-called namespace refers to the various visible ranges of identifiers.
