Question

我在我的应用中使用PSTCollectionView。一切都完美无缺，直到我将我的PSTCollectionViewController的子类添加到UINavigationController链中。当我点击导航控制器的后退按钮时，应用程序与EXC_BAD_ACCESS (code=1, address=0xc0000010)

崩溃

P.S。：我使用ARC。谢谢你的帮助。

这似乎与ARC有关。我通过更改PSTCollectionView.m来修复它，如下所示：

- (void)setDelegate:(id<PSTCollectionViewDelegate>)delegate {
    if( !delegate )
        return;

    //Rest of the function as normal
}

这对我来说没有多大意义，但它有效。
