I've got a zombie appearing in the weirdest place in my program. Here is the
relevant part of the code, using generic names for the methods:
-(void)setUp;
-(void)start;
-(void)changeWords:(NSTimer*)theTimer;
-(NSArray *)wordsInPhrase:(NSString *)thePhrase;
@property (nonatomic, assign) int numWords;
@property (nonatomic, assign) NSUInt wordChangeInterval;
@property (nonatomic, copy) NSString *phrase;
@property (nonatomic, copy) NSArray *words;
@property (nonatomic, copy) NSTimer *wordChangeTimer;
…
- (id)init
{
self = [super init];
if (self) {
phrase = [[NSString stringWithString:@"This is the phrase to display"]
retain];
wordChangeInterval = 0.2;
}
return self;
}
-(void)setUp
{
words = [[self wordsFromPhrase:phrase]] retain];
[self start];
}
-(NSArray *)wordsInPhrase:(NSString *)thePhrase
{
NSArray *wordArray;
[wordArray arrayByAddingObjectsFromArray:[phrase
componentsSeparatedByString:@" "]];
numWords = [wordArray count];
return wordArray;
}
- (void) start
{
currentWordIndex = 0;
wordChangeTimer = [[NSTimer
scheduledTimerWithTimeInterval:wordChangeInterval
target:self
selector:@selector(changeWords:)
userInfo:nil
repeats:YES] retain];
}
- (void)changeWords:(NSTimer*)theTimer
{
currentWordIndex += 1;
if (currentWordIndex > numWords)
currentWordIndex = 0;
messageLayer.string = [self.words objectAtIndex:currentWordIndex];
}
Now, the strangeness: words exists and is OK in setUpDisplay and startDisplay
in that it contains the right words from the phrase. But in changeWords:,
somehow words is nil. I'm at a loss to figure out how words could be released
between start and changeWords:. I'd appreciate some help.
Thanks.
