objective-c - AMShellWrapper 向正在运行的任务发送数据

Question

我正在将AMShellWrapper转换为我自己的应用程序，该应用程序运行具有用户输入的 SH 文件。因此，我需要将数据发送到正在运行的任务。

有任何想法吗？

您需要一种类似于 PseudoTTY.app的不同方法！

@interface PtyView (PtyPrivate)

@implementation PtyView (PtyPrivate)

-(int)count: (NSString *) str {
   static int counter = 0;
   if (   
     ([str rangeOfString:@"Charlie>"].location != NSNotFound ) || \
     ([str rangeOfString:@"[Charlie] user>"].location != NSNotFound )

  {
     counter++;
  }
  return counter;

-(void)startTask

   NSString * cmd = @"/path/to/charliebot/server.sh";

-(void) didRead: (NSNotification *)noty

   NSData * data = [[noty userInfo] objectForKey:NSFileHandleNotificationDataItem];

   if ([data length] == 0)
      return; // end of file

   NSString * str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

   int printvar = [self count: str];

   if   (printvar < 1 )
   {
      [self insertText: @"."];
      [str release];
      [[noty object] readInBackgroundAndNotify];
