During xcode debugging, you can directly use the Mac desktop file as the storage location for iOS debugging.

For example, we need to store the data in the sandbox and then judge and detect the file.

Nsarray* Paths =
Nssearchpathfordirectoriesindomains(Nsdocumentdirectory,
Nsuserdomainmask,Yes);

Nsstring* Docudir = [paths
Objectatindex: 0];

Nsstring * savedfilename = [docudir stringbyappendingpathcomponent: @ "data"];

// For more convenient use, we can directly use the following string during storageCodeAnd write it to this file. After running the file, you will find that the file is already on the desktop and has been written to Data.

Nsstring* Savedfilename =
@ "/Users/Heqin/desktop/Data";

This method is helpful for debugging.
