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.
