iOS自定义UIDatepicker日期选择器视图分享

由于项目需要，需要定制一个日期选择器，找了半天没找到合适的就自己写了个demo

自定义uidatepicker日期选择器视图

效果如下：

下面贴上相关代码：

viewcontroller：

<pre name="code" class="objc">- (void)viewdidload {
 [super viewdidload];
 // do any additional setup after loading the view, typically from a nib.
 self.view.backgroundcolor = [uicolor whitecolor];
 
 if (!_picker || _picker == nil) {
  _picker = [[datepicker alloc] initwithframe:cgrectmake(0, 120, 375, 667)];
  _picker.backgroundcolor = [uicolor whitecolor];
  _picker.delegate = self;
  [self.view addsubview:_picker];
  _picker.hidden = yes;
 }
 [self creatcustombutton];
 
}
- (void)creatcustombutton{
 uibutton *button = [uibutton buttonwithtype:uibuttontypecustom];
 button.frame = cgrectmake(120, 20, 100, 40);
 [button settitle:@"日期选择器" forstate:uicontrolstatenormal];
 [button settitlecolor:[uicolor redcolor] forstate:uicontrolstatenormal];
 [button addtarget:self action:@selector(buttonaction:) forcontrolevents:uicontroleventtouchupinside ];
 [self.view addsubview:button];
}
- (void)buttonaction:(uibutton *)sender
{
 if (!_picker || _picker == nil) {
  _picker = [[datepicker alloc] initwithframe:cgrectmake(0, 120, 375, 667)];
  _picker.backgroundcolor = [uicolor whitecolor];
  _picker.delegate = self;
  [self.view addsubview:_picker];
 }else{
  _picker.hidden = no;
 }
 
}
-(void)datepickerdelegateenteractionwithdatapicker:(datepicker *)picker{
 nslog(@"======>%@",picker.date);
 nsstring *datestr = [nsstring stringwithformat:@"%@",picker.date];
 [_picker removefromsuperview];
 _picker = nil;
 [[[uialertview alloc]initwithtitle:@"提示" message:datestr delegate:self cancelbuttontitle:nil otherbuttontitles:@"确定", nil] show];
 
 
}
- (void)didreceivememorywarning {
 [super didreceivememorywarning];
 // dispose of any resources that can be recreated.
}
