所以我正在使用该框架进行DropDown：https://github.com/AssistoLab/DropDown
我正在尝试将DropDown放在我的UITextField上，但是不知何故它不允许我这样做。它只显示在左上角，一直到右侧。我试图这样设置：
func setupDropDown() {
dropDown.anchorView = view
dropDown.direction = .bottom
dropDown.frame = CGRect(x: screenRect.size.width/2 - 30, y: 70, width: screenRect.size.width/2 + 10, height: 30)
dropDown.dataSource = myArray
dropDown.selectionAction = { [weak self] (index, item) in
self!.exerciseNameTextField.text = "\(item)"
}
dropDown.cancelAction = { [unowned self] in
self.dropDown.deselectRow(self.dropDown.indexForSelectedRow!)
}
}
无论我将dropDown.frame = CGRect(...)更改为什么，它都不会更改任何内容。有什么想法吗？
编辑：
当我尝试他们的演示时，它会附加在UITextField上，但不会结束：
func setupChooseArticleDropDown() {
dropDown.anchorView = exerciseNameTextField
// Will set a custom with instead of anchor view width
// dropDown.width = 100
// By default, the dropdown will have its origin on the top left corner of its anchor view
// So it will come over the anchor view and hide it completely
// If you want to have the dropdown underneath your anchor view, you can do this:
dropDown.bottomOffset = CGPoint(x: 0, y: exerciseNameTextField.bounds.height)
// You can also use localizationKeysDataSource instead. Check the docs.
dropDown.dataSource = [
"iPhone SE | Black | 64G",
"Samsung S7",
"Huawei P8 Lite Smartphone 4G",
"Asus Zenfone Max 4G",
"Apple Watwh | Sport Edition"
]
// Action triggered on selection
dropDown.selectionAction = { [weak self] (index, item) in
//self?.exerciseNameTextField.setTitle(item, for: .normal)
self!.exerciseNameTextField.text = item
}
dropDown.multiSelectionAction = { [weak self] (indices, items) in
print("Muti selection action called with: \(items)")
if items.isEmpty {
//self?.exerciseNameTextField.setTitle("", for: .normal)
self!.exerciseNameTextField.text = ""
}
}
}
