controller中view的代码如下
#pragma mark - 重载系统的hitTest方法
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
ViewController *currentVC = (ViewController *)self.nextResponder;
currentVC.printPoint = point;
if ([self.topView pointInside:point withEvent:event]) {
self.scrollView.scrollEnabled = NO;
if (self.scrollView.contentOffset.x < kScreen_Width *0.5) {
return self.firstTableView;
} else {
return self.secondTableView;
}
} else {
self.scrollView.scrollEnabled = YES;
return [super hitTest:point withEvent:event];
}
}
#pragma mark - 添加手势的相应方法
- (void)tapGestureAction:(UITapGestureRecognizer *)gesture
{
CGPoint point = [gesture locationInView:self.topView];
if (CGRectContainsPoint(self.topView.leftBtnFrame, point)) {
if (self.scrollView.contentOffset.x > 0.5 * kScreen_Width) {
[self.scrollView setContentOffset:CGPointMake(0, 0) animated:NO];
self.topView.selectedItemIndex = 0;
}
} else if (CGRectContainsPoint(self.topView.rightBtnFrame, point)) {
if (self.scrollView.contentOffset.x < 0.5 * kScreen_Width) {
[self.scrollView setContentOffset:CGPointMake(kScreen_Width, 0) animated:NO];
self.topView.selectedItemIndex = 1;
}
}
}
#pragma mark - firstTableView的代理方法scrollViewDidScroll
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
CGFloat placeHolderHeight = self.topView.height - self.topView.itemHeight;
CGFloat offsetY = scrollView.contentOffset.y;
if (offsetY >= 0 && offsetY <= placeHolderHeight) {
self.topView.y = -offsetY;
}
else if (offsetY > placeHolderHeight) {
self.topView.y = - placeHolderHeight;
}
else if (offsetY <0) {
self.topView.y = - offsetY;
}
}
#pragma mark - secondTableView的代理方法scrollViewDidScroll
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
CGFloat placeHolderHeight = self.topView.height - self.topView.itemHeight;
CGFloat offsetY = scrollView.contentOffset.y;
if (offsetY >= 0 && offsetY <= placeHolderHeight) {
self.topView.y = -offsetY;
} else if (offsetY > placeHolderHeight) {
self.topView.y = - placeHolderHeight;
} else if (offsetY <0) {
self.topView.y = - offsetY;
}
}
