本文介绍了一个自定义的iOS日期选择器视图组件，该组件使用UIKit框架实现，包括日期选择器、顶部工具栏及按钮等元素。通过设置最大最小日期限制与委托方法，可以轻松集成到应用中。

//日期弹窗视图
@interface WalletDateActionView : WalletActionView{
NSDate *actionDate;
NSDate *actionMaxDate;
NSDate *actionMinDate;
id <WalletDateActionViewDelegate> delegate;
@private
UIToolbar *_topBar;
UIActionSheet *_action;
UIDatePicker *_picker;
}
//选中日期
@property (nonatomic, retain) NSDate *actionDate;
//最大日期
@property (nonatomic, retain) NSDate *actionMaxDate;
//最小日期
@property (nonatomic, retain) NSDate *actionMinDate;
//Delegate
@property (nonatomic, assign) id <WalletDateActionViewDelegate> delegate;
//弹出视图
- (void)showInView:(UIViewController *)aViewController;//modify by mgqx
//撤销视图
- (void)dismiss;
@end

@protocol WalletDateActionViewDelegate <NSObject>
@optional
//确定提交日期
- (void)dateAction:(WalletDateActionView *)dateAction submitWithDate:(NSDate *)date;

@end
