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: PickerViewTypeData];
// 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);
}];
