Question

我看到iOS floating button over table view关于如何创建浮动按钮。这是我创建按钮的方式。问题是按钮将滚动表格视图。

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self 
           action:@selector(aMethod:)
 forControlEvents:UIControlEventTouchDown];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[view addSubview:button];

我该如何解决？

我建议你使用https://github.com/gizmoboy7/VCFloatingActionButton这个链接....希望它能为你效用

Answer 1

将视图控制器指定为表视图的委托，并覆盖scrollViewDidScroll:

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    if ([scrollView isEqual:self.tableView]) {
        self.floatingButton.transform = CGAffineTransformMakeTranslation(0, scrollView.contentOffset.y);     
    }
}

Answer 2

试试这个：

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    CGPoint origin = [scrollView contentOffset];
    [scrollView setContentOffset:CGPointMake(0.0, origin.y)];

    if ([scrollView.panGestureRecognizer translationInView:scrollView].y > 0)
    {
        NSLog(@"Now TableView Scrolling UP");
        // Your Custom Code
    } 
    else 
    {
        NSLog(@"Now TableView Scrolling Down");
        // Your Custom Code
    }
}
