如何在单击按钮时显示日历并在标签中显示所选日期？ - iOS Objective C

Question

我有一个selectDateLabel和一个selecteDateButton。如何在单击selecteDateButton并在selectDateLabel上显示选定日期时显示日历？

Answer 1

我不认为有内置的日历日期选择器，但常规的UIDatePicker可能适合你。

编辑：或与开放源码库去像PDTSimpleCalendar

Answer 2

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init]; 
[dateFormat setDateFormat:@"cccc, MMM d, hh:mm aa"]; 
NSLog(@"%@",[dateFormat stringFromDate:[NSDate date]]); 

写这段代码在你的按钮操作。

Answer 3

此代码将为您提供完整的图形日期选择器。

按钮点击方法

- (IBAction)btnDel:(id)sender { 
     UIDatePicker* datPick = [[UIDatePicker alloc] init]; 
     datPick.autoresizingMask = UIViewAutoresizingFlexibleWidth; 
     datPick.datePickerMode = UIDatePickerModeDate; 
     [datPick addTarget:self action:@selector(dueDateChanged:) forControlEvents:UIControlEventValueChanged]; 
     CGSize pickerSize = [datPick sizeThatFits:CGSizeZero]; 
     datPick.frame = CGRectMake(0.0, 300, pickerSize.width, 300); 
     [self.view addSubview:datPick]; 
    } 

    -(void) dueDateChanged:(UIDatePicker *)sender { 
     NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init]; 
     [dateFormatter setDateStyle:NSDateFormatterLongStyle]; 
     [dateFormatter setTimeStyle:NSDateFormatterNoStyle]; 
     NSLog(@"Picked the date %@", [dateFormatter stringFromDate:[sender date]]); 
    }
