如何在ios上观察coreplot中的触摸事件？

发布于 2024-11-02 05:36:01 字数 196 浏览 3 评论 0原文

我将此代码添加到我的 graphViewController 中：

-(BOOL)pointingDeviceDownEvent:(id)event atPoint:(CGPoint)interactionPoint {
    NSLog(@"Touched.");
}

但它不会在触摸时触发。我做错了什么？

原文

I added this code to my graphViewController:

-(BOOL)pointingDeviceDownEvent:(id)event atPoint:(CGPoint)interactionPoint {
    NSLog(@"Touched.");
}

but it is not firing on touch. What am I doing wrong?

我正在使用 CPPlotSpaceDelegate 协议来接收 ios 上的触摸。

设置 defaultPlotSpace 的委托后，当收到触摸时，您将调用以下方法

-(BOOL)plotSpace:(CPPlotSpace *)space shouldHandlePointingDeviceUpEvent:(id)event atPoint:(CGPoint)point;

-(BOOL)plotSpace:(CPPlotSpace *)space shouldHandlePointingDeviceCancelledEvent:(id)event;

-(BOOL)plotSpace:(CPPlotSpace *)space shouldHandlePointingDeviceDownEvent:(id)event atPoint:(CGPoint)point;

-(BOOL)plotSpace:(CPPlotSpace *)space shouldHandlePointingDeviceDraggedEvent:(id)event atPoint:(CGPoint)point;

i'm using the CPPlotSpaceDelegate protocol to receive touches on ios.

after setting the delegate for your defaultPlotSpace you'll get called on the following methods when touches are received

-(BOOL)plotSpace:(CPPlotSpace *)space shouldHandlePointingDeviceUpEvent:(id)event atPoint:(CGPoint)point;

-(BOOL)plotSpace:(CPPlotSpace *)space shouldHandlePointingDeviceCancelledEvent:(id)event;

-(BOOL)plotSpace:(CPPlotSpace *)space shouldHandlePointingDeviceDownEvent:(id)event atPoint:(CGPoint)point;

-(BOOL)plotSpace:(CPPlotSpace *)space shouldHandlePointingDeviceDraggedEvent:(id)event atPoint:(CGPoint)point;
