【macOS-两种方式打开文件(调用Shell脚本|macOS-两种方式打开文件(调用Shell脚本 or Core Service)】方式一. 调用自建Shell脚本指定APP打开文件

- (IBAction)useShell:(id)sender { //[self invokingShellScriptAtPath:@"/Users/victor/Desktop/ShellStudy/OpenFile.sh" ]; NSArray *paths = [NSArray arrayWithObjects:@"/Users/victor/Pictures/ad.txt", @"/Users/victor/Pictures/asdfasd.txt",nil]; NSString *appPath = @"/Applications/Google Chrome.app"; NSMutableDictionary *dic = [NSMutableDictionary dictionaryWithCapacity:0]; [dic setValue:paths forKey:kOpenFileWithFilePathArray]; [dic setValue:appPath forKey:kOpenFileWithApplictionPath]; [self excuteShellWithParams:dic shellScriptPath:@"/Users/victor/Desktop/ShellStudy/OpenFile.sh"]; }-(id)excuteShellWithParams:(NSDictionary*)dic shellScriptPath:(NSString*)shellScriptPath { NSString *applicationPath = [dic valueForKey:kOpenFileWithApplictionPath]; NSArray *filePaths = [dic valueForKey:kOpenFileWithFilePathArray]; NSTask *task = [[NSTask alloc] init]; task.launchPath = @"/bin/sh"; NSMutableArray *arguments = [NSMutableArray arrayWithCapacity:0]; [arguments addObject:shellScriptPath]; if (applicationPath && applicationPath.length > 0) { [arguments addObject:@"-a"]; [arguments addObject:applicationPath]; } if (filePaths && filePaths.count > 0) { for (NSString *path in filePaths) { [arguments addObject: path]; } }task.arguments = [NSArray arrayWithArray:arguments]; task.currentDirectoryPath = [[NSBundlemainBundle] resourcePath]; NSPipe *outputPipe = [NSPipe pipe]; [task setStandardOutput:outputPipe]; [task setStandardError:outputPipe]; NSFileHandle *readHandle = [outputPipe fileHandleForReading]; [task launch]; [task waitUntilExit]; NSData *outputData = [readHandle readDataToEndOfFile]; NSString *outputString = [[NSString alloc] initWithData:outputData encoding:NSUTF8StringEncoding]; NSLog(@"Victor-Debug : \n%@",outputString); return outputString; }

NSTask 调用执行shell脚本提示没有权限 Operation not permitted ，是因为沙盒机制

macOS-Cocoa开发之沙盒机制及访问Sandbox之外的文件

shell脚本：
OpenFile.sh

#!/bin/shprintHelpDoc() { printf "Usage: ./OpenFile.sh [-a ] [filenames] [--args arguments]\n" printf "Help: Open opens files from a shell.\n\tBy default, opens each file using the default application for that file. \n\tIf the file is in the form of a URL, the file will be opened as a URL.\n" printf "Options:\n" printf "\t-aOpens with the specified application.\n\n\n" }#params count paramCount=$# printf "paramCount=$paramCount\n"#是否包含第1个参数 if [ -z "$1" ]; then printf "Please enter the valid arguments\n" #printHelpDoc exit 1 eliftest $1 = "-a" then if [ -z "$2" ]; then printf "Please enter the valid arguments\n" exit 1 fi fifor (( i = 1; i <= paramCount; i++ )); do #statements params[i-1]="${!i}" echo ${params[i-1]} donefirstArg="${params[0]}" secondArg="${params[1]}" index=0 if test $firstArg = "-a" ; then let index=2 fiif [ $index -eq $paramCount ]; then printf "open $firstArg $secondArg\n" open "$firstArg" "$secondArg" else for (( i = index; i < paramCount; i++ )); do #statements arg="${params[i]}" if test $firstArg = "-a" ; then printf "$i open $firstArg $secondArg $arg\n" open "$firstArg" "$secondArg" "$arg" else open "$arg" fi done fi

方式二: Core Service

//applyToAll 将改程序设置为该文件类型的默认打开程序 + (void)openItems:(NSArray *)itemsFullPaths withApplicationPath:(NSString *)applicationPath open:(BOOL)openWith applyToAll:(BOOL)applyToAll {if (!applicationPath) { NSURL* defaultAppURL = nil; [OpenFileWithApplication applicationsSetForItems: itemsFullPaths defaultURL: &defaultAppURL]; applicationPath = [defaultAppURL path]; }if (!applicationPath)// no application found. Thus do nothing { return; }NSMutableArray* itemsArray = [NSMutableArray arrayWithCapacity:0]; LSLaunchURLSpec launchSpec = {0}; launchSpec.appURL = (__bridge CFURLRef)[NSURL fileURLWithPath: applicationPath isDirectory:YES]; launchSpec.itemURLs = (__bridge CFArrayRef)itemsArray; launchSpec.launchFlags = kLSLaunchDefaults; for(NSString* fullPath in itemsFullPaths) { NSURL* itemURL = [NSURL fileURLWithPath: fullPath]; [itemsArray addObject:itemURL]; if (applyToAll) { NSBundle* appBundle = [NSBundle bundleWithPath: applicationPath]; NSString* contentType = nil; NSError* err = nil; [itemURL getResourceValue:&contentType forKey:NSURLTypeIdentifierKey error:&err]; if (nil == err) { OSStatus status = LSSetDefaultRoleHandlerForContentType ((__bridge CFStringRef)contentType,kLSRolesAll,(__bridge CFStringRef)[appBundle bundleIdentifier]); if ( noErr != status) { NSLog(@"LSSetDefaultRoleHandlerForContentType ERROR: %d", status); }} } }OSStatus status = noErr; if (openWith && [itemsArray count]) { status = LSOpenFromURLSpec(&launchSpec,NULL); if ( noErr != status) { NSLog(@"LSOpenFromURLSpec ERROR: %d", status); } }//assert(status==noErr); }
