我正在尝试实现一个重写UITextViews InputView的TableView,以向用户提供可搜索的TableView,然后使用选定的值填充UITextField。
我已经搜索了相当多的内容,找到的最接近的解决方案是this,但是我不确定如何将UITableViewController关联到UITextViews InputView?
我看到这些函数在MultiSelectPicker中被调用...
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
override func numberOfSectionsInTableView(tableView: UITableView) -> Int
但是这些不是我可以确定地解释的原因,为什么我在表格视图中看不到任何内容。
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
我已经更改了didSet,所以我知道从主线程调用reloadData还是什么都没有。
var items = [NSObject](){
didSet{
dispatch_async(dispatch_get_main_queue(),{
self.tableView.reloadData()
});
}
}
这可能与我在主viewcontroller中设置inputView的方式有关,但是我对于iOS和Swift还是相当陌生,所以我可能缺少一些基本知识。
@IBOutlet weak var mspEmployee: MultiSelectPicker!
let employeePickerView = MultiSelectPicker()
employeePickerView.items = self.oEmployees
self.mspEmployee = employeePickerView
self.txtEmployee.inputView = self.mspEmployee.view
这真的让我发疯,所以任何帮助都将不胜感激!
最佳答案
您需要子类化UITextField,并将inputView设置为UITableView的视图。这是我最近做过的一些类似事情的实现。
class BaseTextField: UITextField{
//Base textfield so that all custom textfields inherit the disabling of certain uitextfield things
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
//disabling menu, autocorrection and copy paste functionality
autocorrectionType = UITextAutocorrectionType.No
inputAssistantItem.leadingBarButtonGroups = []
inputAssistantItem.trailingBarButtonGroups = []
}
override func canPerformAction(action: Selector, withSender sender: AnyObject?) -> Bool {
NSOperationQueue.mainQueue().addOperationWithBlock { () -> Void in
UIMenuController.sharedMenuController().setMenuVisible(false, animated: false)
}
return false
}
}
class OptionSelectText: BaseTextField{
let picker:OptionPicker //this is the UITableViewController I Use for selecting values
required init?(coder aDecoder: NSCoder) {
picker = OptionPicker()
picker.view.translatesAutoresizingMaskIntoConstraints = false
super.init(coder: aDecoder)
picker.delegate = self
let toolbar = UIToolbar(frame: CGRect(x: 0, y: 0, width: picker.view.frame.width, height: 44))
let doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Plain, target: self, action: #selector(OptionSelectText.pickerViewDoneAction))
let flex = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: self, action: nil)
let clearButton = UIBarButtonItem(title: "Clear", style: UIBarButtonItemStyle.Plain, target:self, action: #selector(OptionSelectText.pickerClearAction))
toolbar.setItems([clearButton, flex, doneButton], animated: false)
toolbar.userInteractionEnabled = true
inputView = picker.view
inputAccessoryView = toolbar
}
}
