Usage

Add the dependency to your?Podfile:

用 Podfile 添加依賴(lài)關(guān)系

platform :bios pod 'TWRPickerSlider’, ‘~> 1.0’ ...

Run?pod install?to install the dependencies.

運(yùn)行 pod install 來(lái)安裝依賴(lài)

Next, import the header file wherever you want to use the picker:

下一步，導(dǎo)入頭文件

#import "TWRSliderStackedView.h" #import "TWRPickerSlider.h"

You should first initialize your?TWRPickerSlider?as such:

你需要用以下的方式來(lái)初始化對(duì)象：

TWRPickerSlider *slider1 = [[TWRPickerSlider alloc] init];

…and assign some objects for the picker:

然后，你可以給 picker 賦值幾個(gè)對(duì)象：

slider1.pickerObjects = @[obj1, obj2, obj3];

Objects passed to the picker can be of any type, provided they conform to the?TWRPickerSliderDatasource?protocol. Said protocol only requires the user to implement the following method, which returns the string that the picker will display for the object:

對(duì)象可以是任意類(lèi)型，你只需要給TWRPickerSliderDatasource提供字符串?dāng)?shù)據(jù)即可：

- (NSString *)twr_pickerTitle;

Then set the picker delegate to be your view controller and implement theTWRPickerSliderDelegate?protocol:

然后設(shè)置代理到你的控制器中，并實(shí)現(xiàn)協(xié)議：

// Set Delegate slider1.delegate = self; // TWRPickerSliderDelegate - (void)objectSelected:(id<TWRPickerSliderDatasource>)selectedObject sender:(TWRPickerSlider *)sender{ NSLog(@"Selected object: %@", [selectedObject twr_pickerTitle]); }

Finally add you?TWRPickerSlider?instance to your view. It will automatically position itself at the bottom of the view and animate / slide when pressed.

最后添加?TWRPickerSlider 到你的view上，它會(huì)自動(dòng)的將它自己添加到底端

Stacking pickers

Alternatively, if you have or want to display more than one picker at a time, you can instantiate a?TWRSliderStackedView?object and assign it an array of?TWRPickerSlider.

另外，如果你想在同一時(shí)間顯示超過(guò)一個(gè)的picker，你可以初始化TWRSliderStackedView對(duì)象，然后在它的數(shù)組對(duì)象中賦值TWRPickerSlider對(duì)象。

TWRSliderStackedView *stack = [[TWRSliderStackedView alloc] init]; stack.sliders = @[slider1, slider2, slider3]; [self.view addSubview:stack];

Again, the stacked view will position itself at the bottom of the current view. If you’re working inside a tab bar controller, or if you don’t want the stacked view to stick at the bottom of the view controller, you can use one of the following two methods:

這個(gè)?stacked view將會(huì)把它自己安置在當(dāng)前view的底部，如果你是在Tab bar控制器中作業(yè)，或者說(shuō)你不想讓stacked view在這個(gè)控制器的底端，你可以用下面的方法來(lái)設(shè)置：

- (instancetype)initWithBottomPadding:(NSUInteger)padding; - (instancetype)initWithTabBar;

See the demo project for more details.
