[iOS]选择开始时间和结束时间
demo:https://download.****.net/download/u012881779/10930215
使用了PGDatePicker进行时间选择
使用了JGProgressHUD进行文本提示
这里的情况是分段选择时间，若单次选择开始和结束时间也可以用类似方式限制结束时间的选择。
原型设计了这种：
实现比较简单，放上code就好了。
#import "GASelectTimeViewController.h"
#import "PGDatePicker.h"
#import "JGProgressHUD.h"
@interface GASelectTimeViewController () <PGDatePickerDelegate>
@property (weak, nonatomic) IBOutlet UITextField *startYMDText; // 开始时间：年月日
@property (weak, nonatomic) IBOutlet UITextField *startHMSText; // 开始时间：时分秒
@property (weak, nonatomic) IBOutlet UITextField *endYMDText; // 结束时间：年月日
@property (weak, nonatomic) IBOutlet UITextField *endHMSText; // 结束时间：时分秒
@property (weak, nonatomic) IBOutlet UIButton *saveBut; // 保存按钮
@property (strong, nonatomic) PGDatePicker *datePicker;

@end示意图：
选择结束时间的“年与日”。因为设置了minimumDate，故可选择的“结束时间年月日”会大于“开始时间的年月日”。
选择结束时间的“时分秒”。因为设置了minimumDate，若“结束时间的年月日”选择和“开始时间的年月日”一致，则选择“时分秒”时只能选择大于“开始时间的时分秒”的时间。
