Hi
I'm just trying to write a simple "Hello, world" program that speaks
the string rather than prints it. I made a simple class, SpeakMe, to
hold the 'guts' of the code. Here's the implementation (SpeakMe.m):
#import <AppKit/NSSpeechSynthesizer.h>
#import "SpeakMe.h"
@implementation SpeakMe
-(id) init
{
NSLog(@"init\n");
self = [super init];
if (self)
{
iDidFinishSpeaking = NO;
speak = [[NSSpeechSynthesizer alloc] init];
[speak setDelegate:self];
}
return self;
}
-(void) doSpeak
{
NSLog(@"doSpeak\n");
NSString *text = @"Hello, Objective See";
[speak startSpeakingString:text];
for ( ;1 ; )
{
if (iDidFinishSpeaking = YES)
{
break;
}
}
}
-(void) speechSynthesizer:(NSSpeechSynthesizer *)sender
didFinishSpeaking:(BOOL)finished
{
NSLog(@"speechSynthesizer:didFinishSpeaking\n");
iDidFinishSpeaking = YES;
}
@end
In main.m, I set up a "SpeakMe *" as:
SpeakMe *speaker = [[SpeakMe alloc] init];
as one would expect. The NSLog shows it (the init method) gets called.
This sets up its speechSynthesizer:didFinishSpeaking delegate (I
hope...). I then call [speaker doSpeak]; in the next line. It, too,
fires - and NSLog shows that. But, shouldn't the "deliberate infinite
loop" keep code execution in the doSpeak method until the delegate gets
called to set the 'iDidFinishSpeaking' variable to YES? NSLog shows
that the program exits normally, so - clearly - the loop exited, but my
output never shows that the speechSynthesizer:didFinishSpeaking
delegate got called...
What's going on here?
