    [tempText release];
}

-(void)checkReadyToProcess

    if (count >= 2) {
        [self processGlyph:firstGlyph withGlyph:secondGlyph];

-(void)dispatchText:(NSString *) theText
{
    answerText.text = theText;

是的。这里是:

NSString *tempText = [[NSString alloc] init];//leaked
tempText = [NSString stringWithFormat:@"%i",answer];//creates new autoreleased object
...
[tempText release]; //causes an eventual crash

您正在分配一个<代码>NSString,将变量替换成一个自动发布NSString,然后将自动发布NSString。这将使记忆泄露(从原来的<代码>NSString)和失控。

相反,只是:

NSString *tempText = [NSString stringWithFormat:@"%i",answer];

你们不必予以释放。
