在网上下载的一个时间选择器，挺简洁好用的，所以进行了改造，加了分类小标题和秒的选择还有代理，希望能帮的上对时间精确度有特殊要求的同胞，直接拷代码上了

在controller中的调用，添加代理<DatePickViewDelegate>
// 实现代理方法
- (void)didClickFinishBtn:(NSArray *)array {
// 点击确定按钮返回时间，数组，六个元素，年月日时分秒
}
// 初始化
- (DatePickerView *)dateView {
if (!_dateView) {
_dateView = [[DatePickerView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 200)];
_dateView.delagate = self;
_dateView.backgroundColor = [UIColor whiteColor];
}
return _dateView;
}
使用
_textField.inputView = self.dateView;
