[wtg934614282]

- (void)aaChartView:(AAChartView *)aaChartView moveOverEventWithMessage:(AAMoveOverEventMessageModel *)message { ... ... }

点击第一次走了，第二次走不了点击相同的数据

[wtg934614282]

这样再点击第一的的时候 不走代理方法，发现网络的web的代理方言也不走

[wtg934614282]

#pragma mark - WKScriptMessageHandler
- (void)userContentController:(WKUserContentController *)userContentController
      didReceiveScriptMessage:(WKScriptMessage *)message {
}

这个方法在第二次点击相同的祝状不走

大佬，有没有方法重置选中状态

[AAChartModel]

AAChartView 的 这个 delegate 方法

/// The delegate method of getting move over event message model
/// @param aaChartView The instance object of chart view
/// @param message User finger move over event message model
- (void)aaChartView:(AAChartView *)aaChartView moveOverEventWithMessage:(AAMoveOverEventMessageModel *)message;

或者说这个 block 方法

/// Chart view getting move over event message model
/// @param handler event handler
- (void)moveOverEventHandler:(AAMoveOverEventBlock)handler;

实际上是获取的手指✋🏻或鼠标🖱的滑动方法, 所以重复点击相同的位置, 无法获得交互事件回调.

[AAChartModel]

所以为 AAChartView 新增了专门获取用户点击事件的方法:

• block 方法(方法 1):

/// Chart view getting click event message model
/// @param handler event handler
- (void)clickEventHandler:(AAClickEventBlock)handler;

• delegate 方法(方法 2):

/// The delegate method of getting click event message model
/// @param aaChartView The instance object of chart view
/// @param message User finger click event message model
- (void)aaChartView:(AAChartView *)aaChartView clickEventWithMessage:(AAClickEventMessageModel *)message;

推荐使用 block 方式来获取点击事件回调.

[AAChartModel]

    [_aaChartView clickEventHandler:^(AAChartView *aaChartView,
                                      AAClickEventMessageModel *message) {
            NSDictionary *messageDic = @{
                @"category":message.category,
                @"index":@(message.index),
                @"name":message.name,
                @"offset":message.offset,
                @"x":message.x,
                @"y":message.y
            };
            
            NSString *str1 = [NSString stringWithFormat:@"🖱🖱🖱🖱 clicked point series element name: %@\n",
                              message.name];
            NSString *str2 = [NSString stringWithFormat:@"user finger clicked!!!,get the click event BLOCK message: %@",
                              messageDic];
            NSLog(@"%@%@",str1, str2);
    }];

如上即可获取用户的点击交互事件回调. 回调信息在控制台打印效果大致如下:

2022-05-22 14:00:46.759099+0800 AAChartKitDemo[38107:1314821] 🖱🖱🖱🖱 clicked point series element name: 2018
user finger clicked!!!,get the click event BLOCK message: {
    category = Go;
    index = 5;
    name = 2018;
    offset =     {
        plotX = "271.79166666667";
        plotY = "73.06109613656781";
    };
    x = 5;
    y = 22;
}

demo 中已新增此示例. 下载运行查看即可.
