Question

我正在使用名为TWRCharts的iOS图表软件，我正在尝试在同一个视图控制器中添加多个图表。我使用Interface Builder添加了UIViews，并使用我的.h文件中的outlet连接它们。当我尝试显示一个图表时，我的主图表显示正常。但是当我尝试添加更多图表时，它们不会出现。我试图颠倒图表绘制的顺序，在这种情况下，会出现一个较小的图表，但没有别的。当我尝试将多个子视图添加到各自的视图时，不会显示任何内容。这是我的.h和.m文件。

·H

#import <UIKit/UIKit.h>
#import "TWRChart.h"

@interface OverviewViewController : UIViewController

- (IBAction)didTapButton:(id)sender;

@property (strong, nonatomic) IBOutlet UIView *mainCircularChartUIView;
@property (strong, nonatomic) TWRChartView *mainCircularChart;

@property (strong, nonatomic) IBOutlet UIView *tapTestCircularChartUIView;
@property (strong, nonatomic) TWRChartView *tapTestCircularChart;

@property (strong, nonatomic) IBOutlet UIView *cogTestCircularChartUIView;
@property (strong, nonatomic) TWRChartView *cogTestCircularChart;

@property (strong, nonatomic) IBOutlet UIView *voiceTestCircularChartUIView;
@property (strong, nonatomic) TWRChartView *voiceTestCircularChart;

@property (strong, nonatomic) IBOutlet UIView *mentalHealthTestControllerUIView;
@property (strong, nonatomic) TWRChartView *mentalHealthTestController;

Answer 1

您可以通过两种方式实施

使用滚动视图

如果您在使用滚动视图时遇到问题

您可以通过使用UITableView中的自定义单元格来实现它。

Answer 2

您是否添加了UIScrollView作为VC的主要子视图？如果没有滚动视图，您的内容将无法滚动

将多个子视图添加到UIView
