Question

我们的iPad应用程序用户中有一小部分但很大比例因我们无法在我们的模拟器或任何设备上复制的错误而崩溃。不确定这是否有所不同，但我们已经与一些用户讨论了这个问题并且他们都在使用iPad 4。

关于如何修复它而不能复制它的任何想法？

这是日志：

以下是initWithFrame：

的实施

- (id)initWithFrame:(CGRect)frame

{

    self = [super initWithFrame:frame];

    if (self) {



        self.synthesizer = [[AVSpeechSynthesizer alloc] init];

        self.synthesizer.delegate = self;

        speechPaused = NO;

        self.button = [UIButton buttonWithType:UIButtonTypeCustom];
        self.button.frame = CGRectMake(0, 0, 64, 64);
        self.button.backgroundColor = [UIColor clearColor];
        self.button.hidden = YES;
        [self.button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal ];
        [self.button addTarget:self action:@selector(playPauseButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
        [self.button setBackgroundImage:[UIImage imageNamed:@"voiceClipIcon"] forState:UIControlStateNormal];

        [self addSubview:self.button];


        NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

        NSString *hasAudio = [prefs objectForKey:@"hasAudio"];


        if([hasAudio isEqualToString:@"1"]  && IS_IOS7==YES)

        {

            self.button.hidden = NO;

        }

    }

    return self;

}

编辑：以下是发生崩溃的地方：

EDSSpeechButton.m line 29
-[EDSSpeechButton initWithFrame:]

第29行：self.button.frame = CGRectMake(0, 0, 64, 64);

更新：与更多用户交谈后，似乎崩溃与第4代iPad隔离。

适用于iOS应用的EXC_BAD_ACCESS KERN_INVALID_ADDRESS - 并非所有用户
