之前实现了一个tableview，和传统的写法一样，最底部是父视图的底部（去除tab高度）
//3. Today Todo TableView
initTaskItem()
self.todoTableView.delegate = self
self.todoTableView.dataSource = self
self.todoTableView.tableFooterView = UIView()
//self.todoTableView.backgroundColor = UIColor.whiteColor()
self.todoTableView.backgroundColor = UIColor.clearColor()
// self.todoTableView.estimatedRowHeight = UITableViewAutomaticDimension
self.todoTableView.registerClass(TaskTableViewCell.self, forCellReuseIdentifier: TaskTableViewCellId)
self.view.addSubview(self.todoTableView)
constrain(todoTableView, newView) {todoTableView, newView in
todoTableView.top == newView.bottom + 10
todoTableView.left == todoTableView.superview!.left
todoTableView.right == todoTableView.superview!.right
//todoTableView.height == HomeNewHeight
todoTableView.bottom == todoTableView.superview!.bottom – TabBarHeight
// todoTableView.bottom == todoTableView.superview!.bottom
}
而初始化了数据initTaskItem后，有了3个row
－》此时，tableview的可视区域，也就是可滚动区域，就只有3行高了：
而即使增加多行，能够滚动的高度，也只有3行高度：
－》此处希望实现，列表的可滚动区域，高度，是随着列表内容的高度去同步增加的
－》这样就不用在有限的高度内滚动列表了
－》而是整个页面的无限高度下，去滚动列表了。
swift tableview add scroll height
infinite scrolling uitableview swift
swift expand uitableview content height
ios – Expand label/cell size based on text size in UITableView Swift – Stack Overflow
ios – Resizing UITableView to fit content – Stack Overflow
去用了：
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
let todoFrameHeight = self.todoTableView.frame.height
let todoContentHeight = self.todoTableView.contentSize.height
gLog.verbose("todoFrameHeight=\(todoFrameHeight), todoContentHeight=\(todoContentHeight)")
//todoFrameHeight=215.0, todoContentHeight=252.5
if todoContentHeight > todoFrameHeight {
let newContentHeight = todoContentHeight – todoFrameHeight
let oldHomeFrame = self.view.frame
let newHomeFrame = CGRectMake(oldHomeFrame.origin.x, oldHomeFrame.origin.y, oldHomeFrame.width, oldHomeFrame.height + newContentHeight)
gLog.verbose("newContentHeight=\(newContentHeight), oldHomeFrame=\(oldHomeFrame), newHomeFrame=\(newHomeFrame)")
//newContentHeight=37.5, oldHomeFrame=(0.0, 0.0, 320.0, 504.0), newHomeFrame=(0.0, 0.0, 320.0, 541.5)
self.view.frame = newHomeFrame
}
}
没用。
swift tableview scroll with parent view
swift – IOS : Make entire view scrollable, not only subview – Stack Overflow
去调整父视图的contentsize
结果self.view没有contentsize
swift self view no contentSize
ios – Swift ScrollView – contentSize can’t take a variable Int – Stack Overflow
ios – Cannot set contentSize of an UIScrollView created via loadView – Stack Overflow
ios – Setting contentSize of UIScrollView that is a child view – Stack Overflow
->
好像是,默认的继承了UIViewController的self.view是普通的UIView：
public class UIViewController : UIResponder, NSCoding, UIAppearanceContainer, UITraitEnvironment, UIContentContainer, UIFocusEnvironment {
public var view: UIView! // The getter first invokes [self loadView] if the view hasn’t been set yet. Subclasses must call super if they override the setter or getter.
@available(iOS 2.0, *)
public class UIView : UIResponder, NSCoding, UIAppearance, UIAppearanceContainer, UIDynamicItem, UITraitEnvironment, UICoordinateSpace, UIFocusEnvironment {
public class func layerClass() -> AnyClass // default is [CALayer class]. Used when creating the underlying layer for the view.
public init(frame: CGRect)
public init?(coder aDecoder: NSCoder)
public var userInteractionEnabled: Bool // default is YES. if set to NO, user events (touch, keys) are ignored and removed from the event queue.
public var tag: Int // default is 0
public var layer: CALayer { get } // returns view’s layer. Will always return a non-nil value. view is layer’s delegate
@available(iOS 9.0, *)
public func canBecomeFocused() -> Bool // NO by default
@available(iOS 9.0, *)
public var focused: Bool { get }
@available(iOS 9.0, *)
public class func userInterfaceLayoutDirectionForSemanticContentAttribute(attribute: UISemanticContentAttribute) -> UIUserInterfaceLayoutDirection
@available(iOS 9.0, *)
public var semanticContentAttribute: UISemanticContentAttribute
}
不支持scrollView中的contentSize：
public class UIScrollView : UIView, NSCoding {
public var contentOffset: CGPoint // default CGPointZero
public var contentSize: CGSize // default CGSizeZero
所以：
看来是要去新建一个scrollView
把当前视图的内容，都放到scrollView中
然后才可以根据子视图tableview的contentsize去更新父scroll视图的contentsize
才可以实现，整个页面的滚动。。
但是又出现：
［未解决］swift中tableview添加到scrollView后无法正常显示
【总结】
然后最后用：
把原先和tableview平级的view，都一股脑的，放到tableview的header view中，即可实现类似的效果了：
滚动tableview话，是整个页面一起滚动的
