ios - tinderSwipeCards 数组人口
<p><p>我正在使用 <a href="https://github.com/cwRichardKim/TinderSimpleSwipeCards" rel="noreferrer noopener nofollow">https://github.com/cwRichardKim/TinderSimpleSwipeCards</a> .我在 viewController 中创建了一个数组，其中数据来自 JSON。我希望只有该数量的卡片将创建为我的 JSON 数组中的数据。请帮助我，我从过去 3 天开始这样做，但尚未成功。</p>
<p>这是我的 ViewController 中的数组</p>
<pre><code>;
//;
NSLog(@"%@",_arrAllCards);
//_draggableVC.allCards = _arrAllCards;
//;
if ( >0) {
DraggableViewBackground *draggableBackground = [initWithFrame:self.invitationViewContainer.frame];
draggableBackground.exampleCardLabels = ;
draggableBackground.alpha = 0; //opti
;
;
}
</code></pre>
<p>而 DraggableViewBackground 是 cwRichardKim 提供的 View 类</p>
<pre><code> - (id)initWithFrame:(CGRect)frame

<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>你能像这样改变你的 -(void)loadCards 方法吗-</p>
<pre><code>-(void)loadCards :(NSArray*) array {
exampleCardLabels = array;
//put here your existing code.
//...
}
</code></pre>
<p>还在 DraggableViewBackground.h 文件中添加 <code>-(void)loadCards :(NSArray*) array;</code></p>
<p>并注释 <code>;</code> 来自 <code>- (id)initWithFrame:(CGRect)frame</code> 方法</p>
<p>然后像这样改变这个方法-</p>
<pre><code>if ( >0) {
DraggableViewBackground *draggableBackground = [initWithFrame:self.invitationViewContainer.frame];
;
draggableBackground.alpha = 0; //opti
;
//;
}
</code></pre></p>
