我有tableViewCell,并且它具有uibutton。我设置了这样的约束:
make.left.equalTo(contentView.snp.left).offset(16)
make.right.equalTo(contentView.snp.right).offset(-16)
make.bottom.equalTo(contentView.snp.bottom).offset(-46)
make.top.equalTo(contentView.snp.top).offset(24)
make.height.equalTo(64)
它的确显示为正确的高度,并将顶部和底部的偏移设置正确,但是在控制台中打印错误登录:
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.
(
"<SnapKit.LayoutConstraint:0x6000002a34e0@RoundedButtonCell.swift#49 POS2.MSButton:0x7faf22c674b0.bottom == UITableViewCellContentView:0x7faf22c672c0.bottom - 46.0>",
"<SnapKit.LayoutConstraint:0x6000000b8600@RoundedButtonCell.swift#50 POS2.MSButton:0x7faf22c674b0.top == UITableViewCellContentView:0x7faf22c672c0.top + 24.0>",
"<SnapKit.LayoutConstraint:0x6000002a3de0@RoundedButtonCell.swift#51 POS2.MSButton:0x7faf22c674b0.height == 64.0>",
"<NSLayoutConstraint:0x604000484420 'UIView-Encapsulated-Layout-Height' UITableViewCellContentView:0x7faf22c672c0.height == 134 (active)>"
)
Will attempt to recover by breaking constraint
<SnapKit.LayoutConstraint:0x6000002a3de0@RoundedButtonCell.swift#51 POS2.MSButton:0x7faf22c674b0.height == 64.0>
我想以某种方式"不喜欢",我以恒定设置Uibutton的高度,并设置了顶部和底部偏移。如何解决?
ps。我的控制器是uitaiteViewController,我像这样配置TableView:
private func setupTable() {
tableView.estimatedRowHeight = 40
tableView.rowHeight = UITableViewAutomaticDimension
tableView.separatorInset = .zero
tableView.separatorColor = .clear
tableView.keyboardDismissMode = .onDrag
tableView.tableFooterView = nil
tableView.tableHeaderView = nil
tableView.delegate = self
tableView.dataSource = self
tableView.register(RadioButtonCell.self, forCellReuseIdentifier: MSTableViewCellType.radioButtonCell.rawValue)
tableView.register(InputViewCell.self, forCellReuseIdentifier: MSTableViewCellType.inputViewCell.rawValue)
tableView.register(CommentViewCell.self, forCellReuseIdentifier: MSTableViewCellType.commentViewCell.rawValue)
tableView.register(RoundedButtonCell.self, forCellReuseIdentifier: MSTableViewCellType.roundedButtonViewCell.rawValue)
}
setupTable
在viewDidLoad
在CellForrow中:
case .roundedButton:
let cell = tableView.dequeueReusableCell(withIdentifier: MSTableViewCellType.roundedButtonViewCell.rawValue, for: indexPath) as! RoundedButtonCell
guard let model = fieldModel as? TextContainViewModel else { return UITableViewCell()}
cell.setup(title: model.title)
cell.contentView.layoutMargins = UIEdgeInsets(top: 24, left: 16, bottom: 46, right: 16)
cell.layoutIfNeeded()
return cell
}
我没有覆盖高度forrowatIndExpath。
问题是您已经明确设置了单元格高度。您不能明确规定行高度,也不能提供一组完整的优先级垂直约束。做一个或另一个。要么明确大小,要么提供不完整的约束,要么提供完整的约束,并将行自动告诉大小。
