ios - 如何在 UIScrollView 中添加多个 UIView
<p><p>我有一个绘制饼图的 UIView，我想以编程方式在 UIScrollView 中放置 3 个或 4 个图表。我该怎么做？</p>
<p>我的h文件是这样的</p>
<pre><code>@class PieChart;
@interface ViewController : UIViewController {
}
@property (weak, nonatomic) IBOutlet UIScrollView *scrollView;
</code></pre>
<p>和m文件</p>
<pre><code>- (void)viewDidLoad
{
;
];
;
scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite;
scrollView.clipsToBounds = YES;
scrollView.scrollEnabled = YES;
scrollView.pagingEnabled = YES;
PieChart *chart = [initWithFrame:CGRectZero];
;
;
}
</code></pre></p>

<p><p>如果需要给 View 添加 subview ，需要使用<code></code>。这是常见的做法。
