ChineseSubdivisionsPicker

ChineseSubdivisionsPicker is a simple Chinese Subdivisions picker inherited from UIPickerView and written in Swift.

You can let user pick province, city and district data from it.

Campatible from iOS7 to iOS9.

Usage

let myPicker = ChineseSubdivisionsPicker() 
//You can also use Interface Builder to create a ChineseSubdivisionsPicker
myPicker.pickerType = .District
myPicker.pickerDelegate = self

Basics

pickerType: ChineseSubdivisionsPicker.ChineseSubdivisionsPickerType

Available picker types are .Province .City and .District Picker type is .District in default.

pickerDelegate: ChineseSubdivisionsPickerDelegate

You should implement subdivisionsPickerDidUpdate() in your pickerDelegate (a UIViewController in usual) to receive callback when picker value is changed.

Note: Delegate method will be called when you set province, city and district value.

province, city, district: String?

You can fetch & set province, city and district name.

Note that you must set these value in logic order (aka. From province to city then to district), and the value you set MUST match exactly with which in ChineseSubdivisions.plist. Value setting MUST perform on main thread.

Note

Changing dataSource or delegate of ChineseSubdivisionsPicker will not work. You should change pickerDelegate instead for receiving callback.

中国行政区划选择器

中国行政区划选择器继承自 UIPickerView,使用 swift 实现。

用户可以选择省、市或区。你可以定制选择器的最小选择粒度。

支持iOS7以上

使用方法

Demo请参考项目主目录下的ChineseSubdivisionsPickerExample.

let myPicker = ChineseSubdivisionsPicker() 
//You can also use Interface Builder to create a ChineseSubdivisionsPicker
myPicker.pickerType = .District
myPicker.pickerDelegate = self

主要类型

pickerType: ChineseSubdivisionsPicker.ChineseSubdivisionsPickerType

可选的选择器类型为 .Province(只可选择省份) .City(可选择省市) and .District (可选择省市区),默认的选择器类型是 .District(可选择省市区)。

pickerDelegate: ChineseSubdivisionsPickerDelegate

你需要在你的 pickerDelegate(通常是一个 UIViewController)里实现 subdivisionsPickerDidUpdate() 方法,ChineseSubdivisionsPicker 会在更新选定的省市区时调用这个方法。

注意,你直接设置 province, city 和 district 属性时也会触发这个回调方法。

province, city, district: String?

可通过 province, city, district 属性获取到目前选择的省市区的名字。 此外,你也可以通过将他们设置为ChineseSubdivisions.plist中的省市区名字从而更新选择器的UI。需要注意,设置省市区必须按照逻辑顺序(即先设置省,接着市,最后设置区),且设置这些属性必须在主线程进行。

特别提醒

注意,ChineseSubdivisionsPicker 的 dataSourcedelegate 修改是不会生效的(始终为Picker自己)。如果你想要接受回调,应该修改 pickerDelegate 属性。
