iOS7移植32位到64位崩溃-iOS7porting32bitto64bitCrash

Why does this code crash in 64 bit? - It works fine 32 bit.

为什么这个代码在64位崩溃？ - 它工作正常32位。

It's loading a nib for a UIView

它正在为UIView加载一个笔尖

- (id) awakeAfterUsingCoder:(NSCoder*)aDecoder {

    BOOL theThingThatGotLoadedWasJustAPlaceholder = ([[self subviews] count] == 0);

    if (theThingThatGotLoadedWasJustAPlaceholder) {

        ALTimelineView* theRealThing = [[self class] loadFromNib];

        // pass properties through
        theRealThing.frame = self.frame;
        theRealThing.autoresizingMask = self.autoresizingMask;
        theRealThing.alpha = self.alpha;
        theRealThing.hidden = self.hidden;

        [theRealThing internalInit];

        // convince ARC that we're legit
        CFRelease((__bridge const void*)self);
        CFRetain((__bridge const void*)theRealThing);

        return theRealThing;
    }
    return self;
}

loadFromNib

loadFromNib

+ (id) loadFromNib {

    NSString* nibName = NSStringFromClass([self class]);
    NSArray* elements = [[NSBundle mainBundle] loadNibNamed:nibName owner:nil options:nil];

    for (NSObject* anObject in elements) {
        if ([anObject isKindOfClass:[self class]]) {
            return anObject;
        }
    }
    return nil;
}

The error I'm getting is EXC_BAD_ACCESS (code=EXC_I386_GPFLT)

我得到的错误是EXC_BAD_ACCESS（代码= EXC_I386_GPFLT）
