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)
文章只是个人笔记,不作指导,错误敬请指正【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
demo:https://gitee.com/personal_development_project/OpenThirdAppDemo.git
- (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);
}
