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];
}然后看輸出：

這是什么平臺？ios嗎？
ios的話，被點擊view重寫touchesBegan:withEvent:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event if (touches.count == 1)//單指操作
{ UITouch *touch = touches.anyObject; CGPoint touchLocation = [touch locationInView:self.window]; NSLog(@"%@",NSStringFromCGPoint(touchLocation));
}舉報
