Nsfilemanager Calculate File/Folder size

In some software, the user will generally show the memory of the current app, while the user can according to their own needs to clear the cached content. In general, the folder is not the size of this property, so you need to traverse the contents of the folder to calculate the size of the folder, the following with Nsfilemanger to achieve this function.

Learn that the file/folder path is a nsstring string type, so you can add a taxonomy to a string if it is a file/folder implementation that calculates its size. The classification is named FileSize.

This allows for the calculation of file/folder size

For example, calculate the size of the caches file

1 nsstring *caches =[[Nssearchpathfordirectoriesindomains (Nscachesdirectory, Nsuserdomainmask, YES) Lastobject]; 2 Integer cachessize = [caches fileSize];

This will give you the size of the caches folder.

If the input string is not a file/folder, get 0.
