PickerView的封装

平时我在使用PickerView的时候，比较麻烦，要配置各种设置，本文就是主要介绍了如何封装了一个比较齐全的PickerView，其中可以直接用DatePickerView的四个基本类型以及一个自定义类型：
PickerViewTypeDate_Time,
PickerViewTypeDate_Date,
PickerViewTypeDate_DateAndTime,
PickerViewTypeDate_Timer,
PickerViewTypeData,
使用的时候，也是很方便的！

开源代码 - Github

使用的时候的代码

 PickerView * picker = [PickerView showPickerViewInView:view withType:button.tag];//    PickerView * picker = [PickerView showPickerViewInkeyWindowTopWithType:button.tag];//    PickerView * picker = [PickerView showPickerViewInVCTop:self withType:button.tag];    picker.dataSources = @[@[@"aaa",@"aab"],@[@"baa",@"bab"],@[@"caa",@"cab",@"cac"]];    // 获取选中的信息    [picker setSelectBlock:^(NSObject *data, BOOL isSureBtn) {        NSLog(@"%@ -- %d",data,isSureBtn);    }];
