UIImagePickerController

标签： ios iphone ios5 ios6 ios7

【解决方案1】：

首先，创建一个 UIImagePickerController

在您的类中，您需要实现 UIImagePickerControllerDelegate 协议并将其连接到选取器上的委托属性。一旦用户选择了某些内容，您应该能够从 didFinishPickingMediaWithInfo 中获取所选媒体的位置。

//检查不在模拟器中的iOS设备

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    // this is the file system url of the media
    NSURL* videoUrl = [info objectForKey:UIImagePickerControllerMediaURL];

    // TODO: read in data at videoUrl and write upload it to your server
}

【讨论】：

imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate = 自我； imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie,nil];这个委托方法没有调用然后我创建 UIImagepicker 的方式如下
你在 .h 文件中声明你的委托
使用这个委托
我在单击照片后在图像中使用了两个代表它 vl 调用此方法 - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 选择视频后它不会调用我面临的问题的方法
@user3092286 如果您声明了委托和分配。然后，当您从图库中选择任何项目时，必须调用它。调试你的代码，看看到底是什么问题。

【解决方案2】：

使用此功能可能会有所帮助

-(void)selectVideoButtonClicked:(id)sender{
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.delegate = self;
    imagePicker.sourceType =    UIImagePickerControllerSourceTypePhotoLibrary;
    imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie,      nil];
    [self presentViewController:imagePicker animated:YES completion:nil];
 }

并委托“UIImagePickerControllerDelegate”并导入框架并使用委托函数从库中选择视频

MobileCoreServices.framework 首先导入到项目中，然后导入到文件 CoreServices/CoreServices.h

- (void) imagePickerController: (UIImagePickerController *) picker didFinishPickingMediaWithInfo: (NSDictionary *) info {
    NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
    // Handle a movie capture
    if (CFStringCompare ((CFStringRef) mediaType, kUTTypeMovie, 0)
        == kCFCompareEqualTo) {
        NSString *moviePath = [[info objectForKey:  UIImagePickerControllerMediaURL] path];
        NSLog(@" Video Path %@",moviePath);
        NSString *fileName = [[NSString alloc]init];

        //If you wants get File Name Then you can use this
        if ([moviePath rangeOfString:@"//"].location != NSNotFound) {
            NSString *separatorString = @"//";
           NSArray *disSplit = [moviePath componentsSeparatedByString:separatorString];
            fileName = disSplit[1] ;
            // [self videoUploadingDirect:moviePath];
        }

        if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (moviePath)) {
            UISaveVideoAtPathToSavedPhotosAlbum (moviePath, nil, nil, nil);
            }
    }
    [self dismissViewControllerAnimated:YES completion:nil];

}

谢谢:)
