Hello everybody,
I'm having a difficult time trying to figure out why cocoa gives me a warning when trying to implement a delegate method in my class.
I'm writing the SpeakLine application from Aaron Hillegass' book in which the user enters a line of text and there's 2 buttons: "Stop" and "Speak".
When the user presses Speak, the speak button should go not enabled and Stop go enable, and when the SpeechSynthesizer finishes the opposite should happen.
Anyway, I set the delegate as self in the init method, like so:
-(id) init {
[super init];
speechSynth = [[NSSpeechSynthesizer alloc] initWithVoice:nil];
[speechSynth setDelegate:self];
return self;
}
and implement the method didFinishSpeaking like this:
-(void) speechSynthesizer:(NSSpeechSynthesizer *)sender didFinishSpeaking:(BOOL)complete {
NSLog(@"Complete = %d", complete);
[startButton setEnabled:YES];
[stopButton setEnabled:NO];
}
I get the warning: "Class 'AppController' does not implement the 'SpeechSynthesizerDelegate' protocol" at the line [speechSynth setDelegate:self];
Is there anything obviously wrong with what I'm doing? I followed the book exactly and still get this warning.
Thanks in advance.
Martin.
