我的Git历史看起来像这样:

我想把紫色的提交压成一个.我不希望在我的提交日志中再次看到它们.

我试过做了git rebase -i 1,但即使1是在蓝色分支上(参见图片),我仍然看到我的紫色分支上的每个提交.

如何完全删除紫色分支(来自提交日志)？

我正在尝试从故事板中特定配置UIPageViewController:

TutorialPageViewController.h

#import <UIKit/UIKit.h>
@interface TutorialPageViewController : UIPageViewController <UIPageViewControllerDelegate, UIPageViewControllerDataSource>
@end

TutorialPageViewController.m

#import "TutorialPageViewController.h"

@interface TutorialPageViewController ()
@property (assign, nonatomic) NSInteger index;
@end

@implementation TutorialPageViewController
{
    NSArray *myViewControllers;
}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.delegate = self;
    self.dataSource = self;
    [self didMoveToParentViewController:self];
    UIStoryboard *tutorialStoryboard = [UIStoryboard storyboardWithName:@"TutorialStoryboard" bundle:[NSBundle mainBundle]];

我想要Facebook app native dialog login(https://developers.facebook.com/docs/technical-guides/iossdk/login/#fbnative).

在控制台中,单击FBLoginView时收到以下消息:

FBSDKLog: Cannot use the Facebook app or Safari to authorize, fb**** is not registered as a URL Scheme

但我完全按照这里做的那样:将Facebook SDK更新为3.5后无法打开活动会话

我正在使用Django REST Framework 2.0.

这是我的模型类:

class Mission(models.Model):
    assigned_to = models.ForeignKey('auth.User',
                                    related_name='missions_assigned',
                                    blank = True)

这是我的观点类:

class MissionList(generics.ListCreateAPIView):
    model = Mission
    serialize_class = MissionSerializer

1. 多部分表单在浏览器中呈现,assigned_to字段为空.

2. 发布原始JSON时,我收到以下错误消息:

Cannot assign None: "Mission.assigned_to" does not allow null values.

这是我的示例代码:

package newslab.video.server;

import android.app.Activity;
import android.hardware.Camera;
import android.os.Bundle;
import android.util.Log;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class VideoServer extends Activity implements SurfaceHolder.Callback {
    TextView testView;

    Camera camera;
    SurfaceView surfaceView;
    SurfaceHolder surfaceHolder;

    private final String tag = "VideoServer";

    Button start, stop;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        start = (Button)findViewById(R.id.btn_start);
        start.setOnClickListener(new Button.OnClickListener() {
            public void onClick(View arg0) {
                start_camera();
            }

我想在jpeg照片中添加经度和纬度等GPS数据.通过标签卡(NFC)捕获照片在logcat中可以显示正确的值,但这些值不能写入jpg照片文件!

下面是我的代码:它用于获取保存的jpg文件并调用下面的方法该方法用于将EXIF GPS参数添加到jpg中经度和纬度等GPS参数已经在另一个活动中使用.

我在Firefox中使用EXIF Viewer来查看结果.

有人可以用字符 - 法语区域设置来解释sort命令的行为吗？

$ file file.txt
file.txt: UTF-8 Unicode text, with CRLF line terminators

$ wc -l file.txt
4 file.txt

$ cat file.txt
cœz
coez
coe
cœ

$ sort file.txt
coe
cœ
cœz
coez

$ sort -d file.txt
cœ
coe
coez
cœz

$ env | grep -P "(LC|FR)"
LANG=fr_FR.UTF-8

"œ"小于或大于"oe"的事实在常规排序的情况下似乎是随机的,而在字典sort(sort -d)的情况下,该字符被简单地忽略.

我想这与整理有关,但我想在这里有一些见解.
