ios 6 and ios 7 處理 不能輸入未來時間的問題

step1

新增一個日期選擇器

MyPickerView *datePickerView;

step2

datePickerView = [MyPickerView getDatePickerViewWithBarForController:self title:@"select time" ];

datePickerView.datePickerView.datePickerMode = UIDatePickerModeDateAndTime;

datePickerView.datePickerView.maximumDate = [NSDate date];

[datePickerView.datePickerView addTarget:self action:@selector(dateChanged:) forControlEvents:UIControlEventValueChanged];

設定最大日期不能超過今天

step3

因為ios6 在秒上沒有處理得很好

再加上dateChanged的方法來處理

-(void)dateChanged:(UIDatePicker*)sender

{

    if([sender.date compare:sender.minimumDate] == NSOrderedSame)

    {

        NSDate* oneSecondAfterPickersDate = [sender.date dateByAddingTimeInterval:1] ;

        [sender setDate:oneSecondAfterPickersDate animated:YES];

    }

}
