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
这是什么平台?ios吗?
ios的话,被点击view重写touchesBegan:withEvent:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event if (touches.count == 1)//单指操作 { UITouch *touch = touches.anyObject; CGPoint touchLocation = [touch locationInView:self.window]; NSLog(@"%@",NSStringFromCGPoint(touchLocation)); }
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:
