viewcontroller 新建一个scrollview 鼠标点击scrollview 获取鼠标点击scrollview上的坐标,坐标是相对scrollview的坐标

解决方案

MyScrollView.h

@interface MyScrollView : UIScrollView@end

MyScrollView.m

@implementation MyScrollView- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {    UITouch *touch = touches.anyObject;    CGPoint touchLocation = [touch locationInView:self.window];    NSLog(@"%@",NSStringFromCGPoint(touchLocation));}

MyViewController.m

#import MyScrollView.h- (void)viewDidLoad {    MyScrollView *v = [[MyScrollView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 300.0f, 300.0f)];    v.backgroundColor = [UIColor grayColor];    [self.view addSubview:v];}

然后看输出:
