How to avoid cover the tableview header view ?

This issue is to solve your requirement, and I'm thinking code refactoring, so is there any suggestion about how to make EmptyKit better. Thanks!

使用sectionsToIgnore虽然能够显示空样式，但是不能滚动了

In the most recent version of EmptyKit, the empty view does not remove when reloading tableview with function tableView.reloadData(). Also forcing the update by tableView.ept.reloadData() still keeps the empty view. When the viewController is viewed again, this is solved.

This also happens in the demo project. Running on simulator and iOS 10. (Version 10.0 (SimulatorApp-726.7

)

Hi,

my problem is, that the tableview does not show the empty view.
In the UI debugger i got the following information:

"height and vertical position are ambiguous for UIView"

This info is for the UIView of the EmptyKit.EmptyView.

In a another TableView everything works as expected.

显示状态时候使用MJ下拉刷新造成当前视图向上偏移大约40像素

When UICollectionView has it's own non-zero contentInset, the vertical centre of the empty view is moving right according to left edge indent

When adding a tableheaderview, the empty view is not aligned correctly, the image is overlapping the tableheaderview. Is this an issue or should this be adjusted using offset?

To reproduce in the example project:

override func viewDidLoad() { super.viewDidLoad() tableView.tableFooterView = UIView() tableView.tableHeaderView = UIView.init(frame: CGRect.init(x: 0, y: 0, width: 300, height: 150)) tableView.tableHeaderView?.backgroundColor = UIColor.black setupEmpty() }

tableView设置了无数据图片后，第一次加载时，会闪一下、也就是reloadData后显示数据之前，先加载无数据页面。

[LayoutConstraints] Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(
"<NSLayoutConstraint:0x600000284060 UIView:0x7fab1b4063a0.centerY == EmptyKit.EmptyView:0x7fab1b40a520.centerY - 44 (active)>",
"<NSLayoutConstraint:0x600000283c00 V:|-(0)-[UIView:0x7fab1b4063a0] (active, names: '|':EmptyKit.EmptyView:0x7fab1b40a520 )>",
"<NSLayoutConstraint:0x600000284380 V:[UIView:0x7fab1b4063a0]-(0)-| (active, names: '|':EmptyKit.EmptyView:0x7fab1b40a520 )>"
)

Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x600000284060 UIView:0x7fab1b4063a0.centerY == EmptyKit.EmptyView:0x7fab1b40a520.centerY - 44 (active)>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

How to customise the button? For example, add cornerRadius.

我用 pod 下的最新版本里 ,没有 prepareButtonForEmpty 这个方法, 无法自定义 button
