Let's start with the function of the footstep: Change the name of the. png image in the Mac Ducuments directory. Preparation: 1. Learn about making a script executable file ". sh" File 2. Learn about the use of the Nsfilemanager class under the OC language 3. Understanding Terminal compilation OC's. m file
Next is the method of production: 1. Create an OC Command line Tool Project
Write the features you need in the project: renaming the picture file:#import<Foundation/Foundation.h>
intMain (intargc,ConstChar* argv[]) {
@autoreleasepool {
Nsfilemanager*filemanager = [NsfilemanagerDefaultmanager];
//get the app hereDocumentsList of files and folders in the folder
Nsarray*documentpaths =Nssearchpathfordirectoriesindomains(nsdocumentdirectory,Nsuserdomainmask,YES);
NSString*documentdir = [DocumentpathsObjectatindex:0];
Nserror*error =Nil;
Nsarray*filelist = [[NsarrayAlloc]Init];
//filelistis an array containing the file name and folder name of all the files under the folder
FileList = [FileManagerContentsofdirectoryatpath:d OcumentdirError:&error];
// The following code can list all the subfolder names in a given folder
Nsmutablearray*filearray = [[NsmutablearrayAlloc]Init];
//obtained in the above procedurefileListfolder names are listed in
for (NSString*fileinchfileList) {
NSString*path = [Documentdirstringbyappendingpathcomponent: file];
if([PathHassuffix:@ ". png"]) {
[FilearrayAddObject:p Ath];
}
}
NSLog(@ "Every Thing in the dir:%@", fileList);
NSLog(@ "All folders:%@", Filearray);
for (inti =0; I < Filearray.Count; i++) {
NSString*filepath = Filearray[i];
NSString*topath = [NSStringstringWithFormat:@ "%@/tree%d.png", documentdir,i+1];
[FileManagerCopyitematpath: FilePathTopath: TopathError:Nil];
}
}
return0;}
2. The next step is to compile the. m file under TerminalOpen the terminal CD to the. m file directory Run command: gcc-framework foundation-o myscript main.m you'll get a myscript executable file.
3. Make executable script file. sh file
To open the Terminal input command:CD Documentsmkdir MyScriptVim changeimgname.shEnter edit mode, input I for editingedit content as:#!/bin/bash./myscript
then press Control+c to exit Edit status input: Wq keep exitingcommand input: chmod +x./changeimgname.shcomplete the critical step and continue looking down:4. Copy the MyScript executable file created by step 2 to the ~/documents/MyScript directory, which is the sibling of the changeimgname.sh file
5. Start experimenting:The CD -to-changeimgname.sh directory is: ~/documents/MyScript (in fact, it is now in this directory) Enter the command.changeimgname.sh
How is not the reaction, no response on the right, now is a step forward to the ~/documents directory of a few. png format pictures, then you can find the ~/documents directory under a few different names of the pictures, really effective oh, come on try it
Make a simple script with OC under MAC
