[jQuery Plugins] summernote的 圖片標題與替代文字編輯外掛

預設的summernote是沒有提供image title與alt的編輯ui，
你可以安裝summernote-image-title來達成這個功能。

[Objective-C] iOS 基本技能: 呼叫相機

超常用的iOS呼叫相機基本技能，測試完記錄一下。

使用UIImagePickerController (簡單、快速)

- (void) initCamera{

    

    NSLog(@"initCamera");

    dispatch_async(dispatch_get_main_queue(), ^{

        UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];

        

        //檢查是否支援此Source Type(相機)

        if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {

            NSLog(@"Access Camera Device");

            

            //設定影像來源為相機

            imagePicker.sourceType =  UIImagePickerControllerSourceTypeCamera;

            imagePicker.delegate = self;

            imagePicker.allowsEditing = YES;

            

            //顯示UIImagePickerController

            [self presentViewController:imagePicker animated:YES completion:nil];

        }

        else {

            //提示使用者，目前設備不支援相機

            NSLog(@"No Camera Device");

        }

    });

    

}

//使用者按下確定時

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    //取得剛拍攝的相片(或是由相簿中所選擇的相片)

    UIImage *image=[info objectForKey:UIImagePickerControllerEditedImage];

    

    //設定ImageView的Image物件，例如：

    //yourImageView.image = image;

    

    [picker dismissViewControllerAnimated:YES completion:^{}];

}

//使用者按下取消時

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {

    //一般情況下沒有什麼特別要做的事情

    

    [picker dismissViewControllerAnimated:YES completion:^{}];

}

使用AV Foundation

優點就是彈性比較大，速度快

[Objective-C] 初試一下 youtube live streaming (二) 實作步驟

找到幾篇有關於直播的教學，但都2014了，還是可以參考一下。
以下簡述使用Youtube直播步驟。

完整流程

以下是最後實作完驗證過的流程，這篇也講的很清楚。
http://octuplus.co/Detalles/2084/Cannot-make-transition-of-my-Youtube-broadcast-to-live-using-Youtube-API

So a bit unclear rule is:

1. ensure you have broadcast and livestream created and ready.
   and ensure that broadcast lifecycle status is not COMPLETE, otherwise recreate broadcast ... so ensure that your broadcast lifecycle status is ready
2. bind broadcast to livestream
3. start publishing video to livestream
4. wait for livestream status active
5. transition to testing (yes, you have to do it instead of moving to live)
6. wait for broadcast lifeCycleStatus to become testing
7. transition to live
8. wait for broadcast lifeCycleStatus to become live

You cannot skip testing and cannot transition from complete to testing or ready.

[ubuntu] 搞壞了sudo...must be owned by uid 0 and have the setuid bit set

sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set

XD不小心下錯了chown的指令，然後sudo就爆了。
搞了一小時還是沒弄好機器，
還是重裝VM的存檔-,,-

[Objective-C] AVPlayer 操作筆記

測試一下用Objective-C播放影片的sample

Sample檔放到專案

前面二個項目要打勾

取得應用程式目錄的檔案

//NSBundle resourcePath

    NSString *filePath=[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"SampleVideo_360x240_30mb.mp4"];

//NSBundle URLForResource

 NSURL *sourceMovieURL = [[NSBundle mainBundle]URLForResource:@"SampleVideo_360x240_30mb" withExtension:@"mp4"];
