Hi,
I'm trying to run a command from my app using NSTask.
Here is the part od the code:
[code]
- (void) DPbitSetReset: (id)sender
{
NSSound *DPbitReset = [NSSound soundNamed: @"DPbitReset.wav"];
NSSound *DPbitSet = [NSSound soundNamed: @"DPbitSet.wav"];
NSTask *DPSetBit0 = [[NSTask alloc] init];
[DPSetBit0 setLaunchPath: @"/usr/local/bin/DPSetBit0"];
// Whether the button state is 1 or 0?
if ([sender state] == 1)
{
// Play the bit set sound
[DPbitSet play];
// Which bit to set on Data Port?
switch ([sender tag])
{
case 110: // DPb0sr
[DPSetBit0 launch];
[DPSetBit0 release];
[StatLine setStringValue: @"Write logical 1 to the data port bit
0."];
break;
case 111: // DPb1sr
[StatLine setStringValue: @"Write logical 1 to the data port bit
1."];
break;
[/code]
I can compile my app but when I run it and use this part of my app, that
is when click on the button which has sender tag: 110, the statement
[DPSetBit0 launch]; has no effect. Why?
If I run from the commandline the command '/usr/local/bin/DPSetBit0' it works.
