IOS 7新特性--UIDatePicker

UIDatePicker在方法上的之前的没有区别，显著的区别就是在显示上。IOS 7的效果还是不错的，主要是没有边框显示。两者结合下就好了。

代码：

UIDatePicker * datePicker=[[UIDatePickeralloc]initWithFrame:CGRectMake(0,40,320,320)];

    NSDateFormatter *dateFormat = [[NSDateFormatteralloc]init];

    [dateFormat setDateFormat:@"yyyy-MM-dd"];

    NSDate *todayDate = [NSDatedate];

    [datePicker setDate:datePicker.date];

    [datePicker setMaximumDate:todayDate];

    [dateFormat release];

    datePicker.datePickerMode=UIDatePickerModeDate;

    [self.viewaddSubview:datePicker];

    //[datePicker addTarget:self action:@selector(pickDidChange:) forControlEvents:UIControlEventValueChanged];

    [datePicker release];
