MAC COCOA call command 调用终端控制台程序

STEP 1

先写一个C++ DOS程序

STEP2

使用NSTask来运行，然后用NSPipe和
NSData来接受运行的结果字符串。

先写一个函数：

/*******************************

 Function : NSTask Class + Terminal(=Windows Command) of MAC OS X

 Description :

 $ ./test_was_call_command_app -sum 2 8 5

 *******************************/

NSString* test_sum(int a,int b,int c)

{

    NSString *path  =  @"/Users/test_was_call_command_app/debug/test_was_call_command_app";

    NSTask *task            = [[NSTask alloc] init];

    task.launchPath = path;

    NSMutableArray *arguments = [[NSMutableArray alloc] init];

    [arguments addObject:@"-sum"];

    NSString *var;

    var =[ NSString stringWithFormat:@"%i",a ];

    [arguments addObject:var];

    var =[ NSString stringWithFormat:@"%i",b];

    [arguments addObject:var];

    var =[ NSString stringWithFormat:@"%i",c ];

    [arguments addObject:var];

    task.arguments  = arguments;

//启动前，添加输出设置＋＋＋

    NSPipe *pipe;

    pipe = [NSPipe pipe];

    [task setStandardOutput: pipe];

    NSFileHandle *file;

    file = [pipe fileHandleForReading];

// ---

    [task launch];

    [task waitUntilExit];

    //运行结束后，得到运行的结果字符串++++++

    NSData *data;

    data = [file readDataToEndOfFile];

    NSString *result_str;

    result_str = [[NSString alloc] initWithData: data

                                   encoding: NSUTF8StringEncoding];

    //---------------------------------

    return result_str;

}

然后在MAIN函数里面调用

int main(int argc,
const char * argv[])

{

@autoreleasepool

{

NSString *rs=test_sum(7,2,20);

int rs_int= [rs intValue];

NSString *show =[NSString
stringWithFormat:@"sum : %i",rs_int ];

CFShow(show);

｝

｝

STEP3

測试。成功！

补充：

// [下面两行能够在MAC APP中点击button打开一个网页] +++

NSURL *web_url = [NSURL
URLWithString:@"http://www.hao123.com/"];

[[NSWorkspace
sharedWorkspace] openURL:web_url];//TEST OK!

// [下面两行能够在MAC APP中点击button打开一个网页] ---

// Launch Apple Mail [test OK!]

[[NSWorkspace
sharedWorkspace]
openURL:[NSURL
URLWithString:@"mailto://info@iphonedevelopertips.com"]];

或者：

- (IBAction)OnClick_BT_OpenURLBySearch:(id)sender

{

//打开网页的另外一种方法，传递一个var [begin] +++

NSString* searchQuery =
@"apple";

// Be careful to always URL encode things like spaces and other symbols that aren't URL friendly

searchQuery =  [searchQuery stringByAddingPercentEscapesUsingEncoding:
NSUTF8StringEncoding];

// Now create the URL string ...

NSString* urlString = [NSString
stringWithFormat:@"http://www.baidu.com/s?wd=%@", searchQuery];

// An the final magic ... openURL!

[[NSWorkspace
sharedWorkspace] openURL:[NSURL
URLWithString:urlString]];

//打开网页的另外一种方法。传递一个var [begin] ---
