iphone - 使用 TapGestureRecognizer 获取坐标 x 和 y

Question

我使用 UITapGestureRecognizer 导出屏幕上手指的 x 和 y 坐标。我能怎么做？

Answer 1

-(void) handleTapGesture:(UIGestureRecognizer *) sender {

    CGPoint tapPoint = [sender locationInView:someView];
    int tapX = (int) tapPoint.x;
    int tapY = (int) tapPoint.y;
    NSLog(@"TAPPED X:%d Y:%d", tapX, tapY);
}

Answer 2

获取接触点的最佳方法之一是来自 CCTouchMoved，如下所示，并全局声明变量，以便您也可以将其用于其他人。

声明“CGPoint *touchLocation;” 在你的头文件中。

-(void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event{
//get locations of touch
touchLocation = [touch  locationInView:[touch view]];
NSLog(@"Touch Points are %f, %f", touchLocation.x, touchLocation.y);

}
