调整NSCollectionViewItem的视图大小 [英] Resize view of NSCollectionViewItem

问题描述

如何以编程方式设置NSCollectionViewItem的视图大小？

How do I programatically set the size of a view of an NSCollectionViewItem?

我尝试在NSCollectionView子类中这样做：

I tried doing this in an NSCollectionView subclass:

@implementation CustomCollectionView

- (NSCollectionViewItem *)newItemForRepresentedObject:(id)object {

    NSCollectionViewItem *newitem = [[self itemPrototype] copy];
    [newitem setRepresentedObject:object];  
    NSView *itemview = [newitem view];
    [itemView setFrame:NSMakeRect([itemView frame].origin.x, [itemView frame].origin.y,         [itemView frame].size.width, 500)];
    return newitem;
}

@end

但是此代码无效。我尝试将用于NSCollectionViewItem的NSView子类化，并将setFrame：添加到initWithCoder方法中，但这样做时出现EXC BAD ACCESS崩溃。

However this code has no effect. I tried subclassing my NSView that I use for the NSCollectionViewItem, and adding setFrame: to the initWithCoder method, but I get an EXC BAD ACCESS crash when I do that.

推荐答案

您可以从Steven Degutis签出此开源NSCollectionView替代方案，巧合的是，我认为它今天才刚刚发布到GitHub（我今天通过Twitter注意到了）：

You might checkout this open source NSCollectionView alternative from Steven Degutis which, coincidentally I think was just posted to GitHub today (I noticed it today via Twitter):

看起来它允许您放置不同高度的物品。

Looks like it allows you to have items with different heights.
