NSTask executed only once
- by Eimantas
I'm having trouble executing different NSTask's. Same launchPath, different arguments. I have a class who's instances administer own NSTask objects and depending on arguments those instances were initialized with - dependent NSTask object is being created. I have two initializers:
// Method for finished task
- (void)taskFinished:(NSNotification *)aNotification {
[myTask release];
myTask = nil;
[self createTask];
}
// Designated initializer
- (id) init {
self = [super init];
if (self != nil) {
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(taskFinished:)
name:NSTaskDidTerminateNotification
object:nil];
[self createTask];
}
return self;
}
// Convenience initializer
- (id)initWithCommand:(NSString *)subCommand {
self = [self init];
if (self)
{
[self setCommand:subCommand];
}
return self;
}
And here 's the createTask method:
- (void)createTask {
// myTask is a property defined as NSTask*
myTask = [[NSTask alloc] init];
[myTask setLaunchPath:@"/usr/bin/executable"];
}
Say I have 3 buttons. Each one creates different class instance with different NSTask objects. But problem is that only first one gets executed. The second ones does not even triger "click" event (via target-action). I think it could be cause of launchPath I'm trying to use, 'cause simple /bin/ls works fine. The same command in terminal has 0 return value (i.e. all is fine). Any guides or gotchas are much appreciated.
