iOS file path-related methods

File path-related methods in nspathutilities, mainly the operation path

A path was obtained

NSString *documents = [Nssearchpathfordirectoriesindomains (nsdocumentdirectory, Nsuserdomainmask, YES) objectAtIndex : 0]; Get the document path <pre name= "code" class= "OBJC" >//---~~~/application/43a22272-f08c-4078-93a9-caf451bf9814/ Documents  //~~~ is omitted

Nsarray *components = [documents pathcomponents]; The elements of each node of the path <pre name= "code" class= "OBJC" >          "/",     Users,     admin,     Library,     Developer,     Coresimulator,     Devices,     "87ab942e-1a11-479c-8010-1f5c36646658",     data,     Containers,     data,     application,     "43a22272-f08c-4078-93a9-caf451bf9814",     Documents

NSString *lastpathcomponent = [documents lastpathcomponent]; The last path node element    //---Documents

NSString *stringbydeletinglastpathcomponent = [documents stringbydeletinglastpathcomponent];//Delete last path node element    // ---~~~/application/3b14dae5-8890-42e1-8dc1-664bb35b6333

NSString *stringbyappendingpathcomponent = [Documents stringbyappendingpathcomponent:@ "New.txt"]; Add a path element    //---~~~/application/20fed3fc-859a-4c56-945a-ffeeb17a93a2/documents/new.txt

NSString *pathextension = [stringByAppendingPathComponent pathextension];  Suffix of file    //---TXT

NSString *stringbydeletingpathextension = [stringByAppendingPathComponent stringbydeletingpathextension]; Remove suffix name    //---~~~/application/20fed3fc-859a-4c56-945a-ffeeb17a93a2/documents/new

NSString *stringbyappendingpathextension = [stringbydeletingpathextension stringbyappendingpathextension:@ "TXT"]; Add suffix name    //---~~~/application/20fed3fc-859a-4c56-945a-ffeeb17a93a2/documents/new.txt

NSString *stringbyabbreviatingwithtildeinpath = [documents Stringbyabbreviatingwithtildeinpath];  To the relative path, the front is omitted with the wave number    //---~/documents

NSString *stringbyexpandingtildeinpath = [Stringbyabbreviatingwithtildeinpath Stringbyexpandingtildeinpath]; Change the relative path to an absolute path

Nsarray *stringsbyappendingpaths = [Documents stringsbyappendingpaths:@[@ "a", @ "B", @ "C.txt"];  Batch join multiple paths, get an array of paths    //---~~~/application/16474b22-b287-4f7c-9931-e7454b83822e/documents/a    //---~~~/ application/16474b22-b287-4f7c-9931-e7454b83822e/documents/b    //---~~~/application/ 16474b22-b287-4f7c-9931-e7454b83822e/documents/c.txt
