Question

当我在iphone 5s iOS 7.1或7.1.1上运行程序时，我收到此错误代码，它在iOS模拟器上运行正常。

libobjc.A.dylib`objc_msgSend:
0x1903a01c0:  cmp    x0, #0
0x1903a01c4:  b.le   0x1903a0230               ; objc_msgSend + 112
0x1903a01c8:  ldr    x13, [x0, 0]
0x1903a01cc:  and    x9, x13, #0x1fffffff8
0x1903a01d0:  ldp    x10, x11, [x9, #16] // this line gives an error
0x1903a01d4:  and    w12, w1, w11
0x1903a01d8:  add    x12, x10, x12, lsl #4

错误是：线程10：EXC_BAD_ACCESS（代码= 1，地址= 0x1a15cbeb8）

这是返回错误但仅在离线时返回的代码。我使用coredata来保存值。

 if([[purchased objectAtIndex:locator]boolValue])
        {
            NSAttributedString *theAttributedString;
            theAttributedString = [[NSAttributedString alloc] initWithString:cellLabel.text
                                                                  attributes:@{NSStrikethroughStyleAttributeName:
                                                                                   [NSNumber numberWithInteger:NSUnderlineStyleSingle]}];
            cellLabel.attributedText = theAttributedString;
            [cellLabel setTextColor:[UIColor colorWithRed:163/255.0f green:135/255.0f blue:138/255.0f alpha:1.0f]];
            [cellLabel1 setTextColor:[UIColor colorWithRed:189/255.0f green:167/255.0f blue:169/255.0f alpha:1.0f]];
            imgView.image = [UIImage imageNamed: @"checkbox-checked.png"];

        }
        else
        {
            [cellLabel setTextColor:[UIColor colorWithRed:60/255.0f green:0/255.0f blue:0/255.0f alpha:1.0f]];
            [cellLabel1 setTextColor:[UIColor colorWithRed:80/255.0f green:37/255.0f blue:37/255.0f alpha:1.0f]];
            imgView.image = [UIImage imageNamed: @"checkbox.png"];
        }

我发现了程序崩溃的原因。这是一个小家伙。

cellLabel.attributedText = theAttributedString;

为什么它可以在线运行，但是当你离线时我就超出了它。任何人都可以解释一下吗？

这是我启用僵尸时的结果。

[NSStringDrawingTextStorage textContainerForAttributedString:containerSize:lineFragmentPadding:]: message sent to deallocated instance 0x170303690
