SPDatePickerView效果图
基于上篇写的自定义UIAlertView，今天写了一个自定义的UIDatePicker，有弹出动画效果，利用block回调监听按钮，用法很简单。代码注释也都写了，有什么问题，留言给我。
直接上代码
用法如下：
SPDatePickerView *datePickerView = [[SPDatePickerView alloc]initWithTitle:@"选择出生日期" datePickerMode:UIDatePickerModeDate selectedDate:nil minimumDate:nil maximumDate:nil cancleBlock:^{
DDLog(@"取消");
}doneBlock:^(NSDate *date){
DDLog(@"确定 %@",date);
}];
[datePickerView show];
