Using Auto Layout in a UITableviewCell

Question

I am trying to use automatic sizing UITableViewin swift using snapKit! The corresponding flags set to UITableVieware as follows:

self.rowHeight = UITableViewAutomaticDimension
self.estimatedRowHeight = 70.0

I have a UITextField defined in my customUITableviewCell class, for example:

var uidTextField: UITextField = UITextField()

and the initial setup of the text field in my custom one UITableViewCelllooks like this:

self.contentView.addSubview(uidTextField)
uidTextField.attributedPlaceholder = NSAttributedString(string: "Woo Hoo", attributes: [NSForegroundColorAttributeName:UIColor.lightGrayColor()])
uidTextField.textAlignment = NSTextAlignment.Left
uidTextField.font = UIFont.systemFontOfSize(19)
uidTextField.returnKeyType = UIReturnKeyType.Done
uidTextField.autocorrectionType = UITextAutocorrectionType.No
uidTextField.delegate = self
uidTextField.addTarget(self, action: "uidFieldChanged", forControlEvents: UIControlEvents.EditingChanged)
uidTextField.snp_makeConstraints { make in 
    make.left.equalTo(self.contentView).offset(10)
    make.right.equalTo(self.contentView)
    make.top.equalTo(self.contentView).offset(10)
    make.bottom.equalTo(self.contentView).offset(10)
}

when I run the code that it disables and gives me an error in the console that reads:

Warning only once: a case has been discovered where the restrictions ambiguously suggest a zero height to represent the contents of a table cell. We are considering unintentional collapse and using standard height instead.

- autoLayout UIControls UITableView?

Answer 1

SnapKit ( ) , . offset(10) bottom, , 10pt .

, :

uidTextField.snp_makeConstraints { make in 
    make.left.equalTo(self.contentView).offset(10)
    make.right.equalTo(self.contentView)
    make.top.equalTo(self.contentView).offset(10)
    make.bottom.equalTo(self.contentView).offset(-10)
}

, :

uidTextField.snp_makeConstraints { make in 
    make.edges.equalTo(contentView).inset(UIEdgeInsetsMake(10, 10, 10, 0))
}

inset(), .

, SnapKit . , .

EDIT. , ( tableView 3 , UITextField):

ViewController:

import UIKit
import SnapKit

class ViewController: UIViewController {
    let tableView = UITableView()

    override func viewDidLoad() {
        super.viewDidLoad()

        view.addSubview(tableView)
        tableView.dataSource = self
        tableView.rowHeight = UITableViewAutomaticDimension
        tableView.estimatedRowHeight = 70
        tableView.registerClass(CustomTableViewCell.self, forCellReuseIdentifier: "CustomCell")

        tableView.snp_makeConstraints { (make) -> Void in
            make.edges.equalTo(view)
        }
    }
}

extension ViewController: UITableViewDataSource {
    func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1
    }

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 3
    }

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("CustomCell", forIndexPath: indexPath)
        return cell
    }
}

CustomTableViewCell

import UIKit

class CustomTableViewCell: UITableViewCell {
    let textField = UITextField()

    override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)

        textField.attributedPlaceholder = NSAttributedString(string: "Woo Hoo", attributes: [NSForegroundColorAttributeName:UIColor.lightGrayColor()])
        textField.textAlignment = NSTextAlignment.Left
        textField.font = UIFont.systemFontOfSize(19)
        textField.returnKeyType = UIReturnKeyType.Done
        textField.autocorrectionType = UITextAutocorrectionType.No
        contentView.addSubview(textField)

        textField.snp_makeConstraints { (make) -> Void in
            make.edges.equalTo(contentView).inset(UIEdgeInsetsMake(10, 10, 10, 0))
        }
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}
