UIDatePicker 在我打印时显示错误的日期

Question

我用 UIDatePicker（时间模式）创建了一个小项目，并将其连接到值更改方法。在该方法中，我将一个 NSLog 与选定的时间一起使用。当我更改 UIDatePicker 的值时，卡纸在我的打印中出现错误的值控制台

例如：当我选择 9:19 AM 我的控制台打印 2015-04-27 03:49:10 +0000

为什么显示不同的值？

我的代码

#import "ViewController.h"

@interface ViewController ()

@property (strong, nonatomic) IBOutlet UIDatePicker *picker;
- (IBAction)pic:(id)sender;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}



   //Value changed method 
    - (IBAction)pic:(id)sender {
        NSLog(@"%@",self.picker.date);
    }
    @end

Answer 1

用这个来记录

[self.picker.date descriptionWithLocale:[NSLocale currentLocale]]

由于时区原因导致日志不对，NSDate在显示日期时会自动调整时间偏移
