公共PopDatePickerView实现
使用方法：
- (void) btnClicked:(id)sender {
// 适应ios6和ios7
if (popDatePickerView == nil) {
if (IS_IOS7) {
popDatePickerView = [[PopDatePieckerView alloc] initWithFrame:CGRectMake(0, [[UIScreen mainScreen] applicationFrame].size.height, 320, 206)];
}
else {
popDatePickerView = [[PopDatePieckerView alloc] initWithFrame:CGRectMake(0, [[UIScreen mainScreen] applicationFrame].size.height, 320, 260)];
}
}
popDatePickerView.backgroundColor = [UIColor clearColor];
popDatePickerView.delegate = self;
// 设置时间格式 如果不设置则显示默认
[popDatePickerView setDatePickerMode:UIDatePickerModeDateAndTime];
// 设置时间显示的格式 如果不设置则显示默认
[popDatePickerView setDateFormatter:[NSString stringWithFormat:@"%@", @"yyyy-MM-dd HH:mm"]];
// 设置时间是否中文显示 如果不设置则显示默认
local = [[NSLocale alloc] initWithLocaleIdentifier:@"zh-Hans"];
[popDatePickerView setDateLocal:local];
[self.view addSubview:popDatePickerView];
[self startAnimation];
}
- (void) doneBarButtonItemClicked:(NSString *)strDate {
[self stopAnimation];
}
#pragma mark 简单动画
- (void) startAnimation {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];

if (IS_IOS7) {
popDatePickerView.frame = CGRectMake(0, [[UIScreen mainScreen] applicationFrame].size.height - 206, 320, 206);
}
