將記錄的視頻保存到文檔文件夾中

Question

我試圖在錄製文件後將文件夾中的影片保存到文件夾中。

這是我的代碼：

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



    NSString *moviePath = [[info objectForKey:UIImagePickerControllerMediaURL] path]; 
    [self dismissViewControllerAnimated:YES completion:nil]; 
    NSLog(@"path from image picker: %@", moviePath); 

    NSFileManager* fileManager = [NSFileManager defaultManager]; 
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES); 
    NSString* documentsDir = [paths objectAtIndex:0]; 

    NSLog(@"%@",documentsDir); 

    [fileManager moveItemAtPath:moviePath toPath:documentsDir error:nil]; 

    NSArray *files = [fileManager contentsOfDirectoryAtPath:documentsDir 
                error:nil]; 

    for (id object in files) { 
     NSLog(@"%@",object); 
    } 
} 

正如你可能猜到了，這是行不通的。

第一個日誌說：從圖片選擇路徑：/private/var/mobile/Applications/6630FBD3-1212-4ED0-BC3B-0C23AEEFB267/tmp/capture-T0x1e575330.tmp.SQQ2C5/capturedvideo.MOV

秒記錄說：/ var/mobile/Applications/6630FBD3-1212-4ED0-BC3B-0C23AEEFB267/Documents

任何人都知道爲什麼它不工作？

嘗試此代碼，當您保存某些內容時，該文件應具有該文件的文件名和擴展名。在您的代碼中，目標保存路徑就是文檔目錄。那是錯的。使用[documentsDir stringByAppendingPathComponent：filename.extension]會給你正確的目的地filePath，[moviePath lastPathComponent]返回所選文件的文件名+擴展名。

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

    NSString *moviePath = [[info objectForKey:UIImagePickerControllerMediaURL] path]; 
    [self dismissViewControllerAnimated:YES completion:nil]; 
    NSLog(@"path from image picker: %@", moviePath); 

    NSFileManager* fileManager = [NSFileManager defaultManager]; 
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES); 
    NSString* documentsDir = [paths objectAtIndex:0]; 
    NSString *savePath = [documentsDir stringByAppendingPathComponent:[moviePath lastPathComponent]]; 

    NSLog(@"%@",savePath); 

    [fileManager moveItemAtPath:moviePath toPath:savePath error:nil]; 

    NSArray *files = [fileManager contentsOfDirectoryAtPath:documentsDir 
                 error:nil]; 

    for (id object in files) { 
     NSLog(@"%@",object); 
    } 
}
