一、手势
(1) Tap、LongPress...
二、手势在视图间的传递
Class SubView:UIView {
}
SubView *subView = [SubView new];
(1)视图上添加手势
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(annoViewAction:)];
[subView addGestureRecognizer:tapGesture];
(2)手势中获取当前视图
SubView *subview = (SubView*)gesture.view;
(3)touchBegan中获取操作视图
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
CGPoint point = [[touches anyObject] locationInView:self.view];
point = [self.subView1.layer convertPoint:point fromLayer:self.view.layer];
if ([self.subView1.layer containsPoint:point]) {
//处理点击到这个view中要执行的事件
return;
}
}
三、获取View所在的Controller
id responder = self.nextResponder;
while (![responder isKindOfClass: [UIViewController class]] && ![responder isKindOfClass: [UIWindow class]])
{
responder = [responder nextResponder];
}
if ([responder isKindOfClass: [UIViewController class]])
{
// responder就是view所在的控制器
// do something
[responder dismissViewControllerAnimated:YES completion:nil];
}
四、转化坐标系统
4.1转换子视图坐标至目标视图的坐标系
- (CGRect)convertRect:(CGRect)rect toView:(nullable UIView *)view;
