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
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:
2012-10-16 17:53:11.513 Demo[3991:c07] {105, 143}
2012-10-16 17:53:12.627 Demo[3991:c07] {136, 310}
2012-10-16 17:53:14.519 Demo[3991:c07] {277, 313}
2012-10-16 17:53:16.718 Demo[3991:c07] {292, 312}
2012-10-16 17:53:17.344 Demo[3991:c07] {217, 198}
2012-10-16 17:53:17.776 Demo[3991:c07] {152, 155}
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));
}
正文完
