我在我的应用程序中使用 PSTCollectionView。在我将 PSTCollectionViewController 的子类添加到 UINavigationController 链之前，一切都运行良好。当我点击导航控制器的后退按钮时，应用程序崩溃EXC_BAD_ACCESS (code=1, address=0xc0000010)

PS：我使用ARC。感谢帮助。

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，但它确实有效。
