代码:

import UIKit

import Cartography

class TimelineViewController: UITableViewController {

//class TimelineViewController: UIViewController, UITableViewDelegate, UITableViewDataSource{

//    var tableView:UITableView

    var memoItemList:[MemoItem]

    init(){

        self.memoItemList = [MemoItem]()

        super.init(nibName: nil, bundle: nil)

//        self.tableView = UITableView()

//

//        gLog.debug("self.tableView=\(self.tableView)")

    }

   

    required init?(coder aDecoder: NSCoder) {

        fatalError("init(coder:) has not been implemented")

    }

   

    override func viewDidLoad() {

        super.viewDidLoad()

       

        if let tabBarController = self.tabBarController {

            TabBarHeight = tabBarController.tabBar.frame.height //49

        }

        self.tableView.delegate = self

        self.tableView.dataSource = self

        self.tableView.backgroundColor = UIColor.whiteColor()

        self.tableView.separatorStyle = .None

        self.tableView.registerClass(TimelineTableViewCell.self, forCellReuseIdentifier: TimelineTableViewCellId)

//        self.tableView.estimatedRowHeight = TimelineTableViewCellEstimatedRowHeight

        self.view.addSubview(self.tableView)

        constrain(tableView){ tableView in

            //statusBarFrame=(0.0, 0.0, 320.0, 20.0)

            tableView.top == tableView.superview!.top + UIApplication.sharedApplication().statusBarFrame.height

            tableView.bottom == tableView.superview!.bottom – TabBarHeight

            tableView.left == tableView.superview!.left

            tableView.right == tableView.superview!.right

        }

       

        initDemoData()

    }

self.view.addSubview(self.tableView)

self.view.addSubview

之前的:

调试信息是:

(lldb) po self.tableView

<UITableView: 0x7f80dc01b800; frame = (0 20; 375 647); clipsToBounds = YES; autoresize = W+H; gestureRecognizers = <NSArray: 0x7f80da4499f0>; layer = <CALayer: 0x7f80da400080>; contentOffset: {0, 0}; contentSize: {0, 0}>

(lldb) po self.tableView.subviews

▿ 1 elements

  – [0] : <UITableViewWrapperView: 0x7f80da430010; frame = (0 0; 375 647); gestureRecognizers = <NSArray: 0x7f80da42e540>; layer = <CALayer: 0x7f80da430340>; contentOffset: {0, 0}; contentSize: {375, 647}>

(lldb) po self.tableView.subviews[0]

(lldb) po self.tableView.subviews[0].subviews

0 elements

(lldb) po self.tableView.superview

nil

搜:

UITableViewController tableview Can’t add self as subview

然后再去看看现在的frame,是已经有值了:

(lldb) po self.tableView.frame

▿ CGRect

  ▿ origin : CGPoint

    – x : 0.0

    – y : 20.0

  ▿ size : CGSize

    – width : 375.0

    – height : 647.0

(lldb) po UIScreen.mainScreen().bounds

▿ CGRect

  ▿ origin : CGPoint

    – x : 0.0

    – y : 0.0

  ▿ size : CGSize

    – width : 375.0

    – height : 667.0 { … }

所以:

直接去设置对应的frame,好像就可以了?

(lldb) po self.parentViewController

▿ Optional<UIViewController>

  ▿ Some : <QorosSales.MainTabViewController: 0x7f80da61df40>

(lldb) po self.parentViewController?.view

▿ Optional<UIView>

  – Some : <UILayoutContainerView: 0x7f80da4107c0; frame = (0 0; 375 667); autoresize = W+H; layer = <CALayer: 0x7f80da410250>>

(lldb) po self

<QorosSales.TimelineViewController: 0x7f80da44cd40>

(lldb) po self.tableView

<UITableView: 0x7f80dc01b800; frame = (0 20; 375 647); clipsToBounds = YES; autoresize = W+H; gestureRecognizers = <NSArray: 0x7f80da4499f0>; layer = <CALayer: 0x7f80da400080>; contentOffset: {0, 0}; contentSize: {0, 0}>

(lldb) po self.view

<UITableView: 0x7f80dc01b800; frame = (0 20; 375 647); clipsToBounds = YES; autoresize = W+H; gestureRecognizers = <NSArray: 0x7f80da4499f0>; layer = <CALayer: 0x7f80da400080>; contentOffset: {0, 0}; contentSize: {0, 0}>

结果去修正了顶部和底部的高度:

    override func viewDidLoad() {

        super.viewDidLoad()

       

        if let tabBarController = self.tabBarController {

            TabBarHeight = tabBarController.tabBar.frame.height //49

            gLog.debug("TabBarHeight=\(TabBarHeight)")

        }

//        self.tableView.delegate = self

//        self.tableView.dataSource = self

        //self.tableView.backgroundColor = UIColor.whiteColor()

        self.tableView.backgroundColor = UIColor.greenColor()

        self.tableView.separatorStyle = .None

        self.tableView.registerClass(TimelineTableViewCell.self, forCellReuseIdentifier: TimelineTableViewCellId)

//        self.tableView.estimatedRowHeight = TimelineTableViewCellEstimatedRowHeight

//        self.view.addSubview(self.tableView)

//        constrain(tableView){ tableView in

//            //statusBarFrame=(0.0, 0.0, 320.0, 20.0)

//            tableView.top == tableView.superview!.top + UIApplication.sharedApplication().statusBarFrame.height

//            tableView.bottom == tableView.superview!.bottom – TabBarHeight

//            tableView.left == tableView.superview!.left

//            tableView.right == tableView.superview!.right

//        }

       

        gLog.debug("self.view.frame=\(self.view.frame)") //self.view.frame=(0.0, 20.0, 375.0, 647.0)

        self.view.frame = UIEdgeInsetsInsetRect(self.view.frame, UIEdgeInsetsMake(UIApplication.sharedApplication().statusBarFrame.height, 0, TabBarHeight, 0))

        gLog.debug("self.view.frame=\(self.view.frame)")

        //self.view.frame=(0.0, 20.0, 375.0, 598.0)

        //(0.0, 40.0, 375.0, 578.0)

       

        initDemoData()

    }

但是view还是顶部置顶显示了:

觉得很是奇怪:

顶部都设置了40了。

搜:

UITableViewController tableview frame

iphone – How to resize UITableView in UITableViewController with section header – Stack Overflow

如何更改uitableviewcontroller默认tableview的frame啊 | iOS开发 – CocoaChina CocoaChina_让移动开发更简单

结果去:

        constrain(self.view, self.parentViewController!.view){ selfView, parentView in

            //statusBarFrame=(0.0, 0.0, 320.0, 20.0)

            selfView.top == parentView.top + UIApplication.sharedApplication().statusBarFrame.height

            selfView.bottom == parentView.bottom – TabBarHeight

            selfView.left == parentView.left

            selfView.right == parentView.right

        }

也还是出错:

fatalError("No common superview found between \(from.view) and \(to.view)")

ios – Change frame of UITableView of UITableViewController inside UINavigationController – Stack Overflow

iphone – Is an UITableView resizable? Can I assign a different frame? – Stack Overflow

[总结]

此处的iOS自带的UITableViewController,自带的tableView:

@available(iOS 2.0, *)

public class UITableViewController : UIViewController, UITableViewDelegate, UITableViewDataSource {

    public init(style: UITableViewStyle)

    public init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?)

    public init?(coder aDecoder: NSCoder)

    public var tableView: UITableView!

    @available(iOS 3.2, *)

    public var clearsSelectionOnViewWillAppear: Bool // defaults to YES. If YES, any selection is cleared in viewWillAppear:

    @available(iOS 6.0, *)

    public var refreshControl: UIRefreshControl?

}

内部是:

self.view == self.tableView

所以此处如果执行:

self.view.addSubview(self.tableView)

等价于自己添加自己,所以报错:

Can’t add self as subview

解决办法是:

UITableViewController中不能执行:

self.view.addSubview(self.tableView)

-》但是此处就没法去添加对应的约束去控制tableView的高度了。。。

-》而默认的UITableViewController的tableview的顶部,就和状态栏重叠了。。

-》所以:说是,对于UITableViewController

是没有比较好办法去调整tableView的frame的

-》只能自己去实现UIViewController,加上UITableViewDataSource and UITableViewDelegate

-》这和之前自己的用法一样,即没法用UITableViewController了啊。。

-》iOS系统自己实现的UITableViewController,连tableView的frame都不能设置,也太烂了吧。。。

-》算了,懒得理了,还是自己用UIViewController,加上UITableViewDataSource and UITableViewDelegate吧。
