问题描述

我正在构建一个iOS应用程序。我正在使用故事板来构建屏幕，我已经创建了一个包含名称，日期，分钟和最大值等字段的表单。

I am building an iOS app.I am using storyboards to build the screens and i have made a form which contain some fields like Name,Date,min and max.

我遇到的问题是无法在按钮点击时实现日期选择器，当用户选择日期，日期选择器隐藏时，想要在标签中显示所选日期。

I am facing an problem that is not able to implement date picker on button click and when user select the date,date picker hide,want to display selected date in a label.

我用谷歌搜索但找不到一个好的教程或库。
我想在选择器中只显示日期和日期。

I googled but could not find a good tutorial or library. I want to show only days and date in picker.

推荐答案

-(IBAction)datePickerBtnAction:(id)sender
{
    datePicker =[[UIDatePicker alloc]initWithFrame:CGRectMake(0, 0,10, 50)];
    datePicker.datePickerMode=UIDatePickerModeDate;
    datePicker.hidden=NO;
    datePicker.date=[NSDate date];
    [datePicker addTarget:self action:@selector(LabelTitle:) forControlEvents:UIControlEventValueChanged];
    [self.view addSubview:datePicker];
    rightBtn=[[UIBarButtonItem alloc]initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(save:)];
    self.navigationItem.rightBarButtonItem=rightBtn;       
}

-(void)LabelTitle:(id)sender
{
    NSDateFormatter *dateFormat=[[NSDateFormatter alloc]init];
    dateFormat.dateStyle=NSDateFormatterMediumStyle;
    [dateFormat setDateFormat:@"MM/dd/yyyy"];
    NSString *str=[NSString stringWithFormat:@"%@",[dateFormat  stringFromDate:datePicker.date]];
    //assign text to label
    label.text=str; 
}

-(void)save:(id)sender
{
    self.navigationItem.rightBarButtonItem=nil;
    [datePicker removeFromSuperview];       
}
