从本地选择视频，或者用UIImagePickerController录制视频
小编也是第一次做视频上传，参考
http://blog.csdn.net/personsky/article/details/52471354实现的
//选择本地视频
- (void)choosevideo
{
UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
ipc.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;//sourcetype有三种分别是camera，photoLibrary和photoAlbum
NSArray *availableMedia = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];//Camera所支持的Media格式都有哪些,共有两个分别是@"public.image",@"public.movie"
ipc.mediaTypes = [NSArray arrayWithObject:availableMedia[1]];//设置媒体类型为public.movie
[self presentViewController:ipc animated:YES completion:nil];
ipc.delegate = self;//设置委托
}
//录制视频
- (void)startvideo
{
UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
ipc.sourceType = UIImagePickerControllerSourceTypeCamera;//sourcetype有三种分别是camera，photoLibrary和photoAlbum
ipc.cameraDevice = UIImagePickerControllerCameraDeviceFront;
NSArray *availableMedia = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];//Camera所支持的Media格式都有哪些,共有两个分别是@"public.image",@"public.movie"
ipc.mediaTypes = [NSArray arrayWithObject:availableMedia[1]];//设置媒体类型为public.movie
[self presentViewController:ipc animated:YES completion:nil];
ipc.videoMaximumDuration = 30.0f;//30秒
ipc.delegate = self;//设置委托
//在录制视频的界面添加点东西
UIView *BgView = [[UIView alloc] init];
BgView.LYW_X = LYWScreenWidth*0.5 - 150*X6Scale;
BgView.LYW_Y = 40*Y6Scale;
BgView.LYW_W = 300*X6Scale;
BgView.LYW_H = 200*Y6Scale;
UILabel *lab = [[UILabel alloc] init];
lab.LYW_X = 0;
lab.LYW_Y = 0;
lab.LYW_W = 300*X6Scale;
lab.LYW_H = 200*Y6Scale;
lab.text = @“http://www.jianshu.com/u/0158007b8d17”;
lab.numberOfLines = 0;
lab.textColor = [UIColor orangeColor];
[BgView addSubview:lab];
ipc.cameraOverlayView = BgView;
}
视频录制完成，保存到相册
//完成视频录制，并压缩后显示大小、时长
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSURL *sourceURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSLog(@"%@",[NSString stringWithFormat:@"%f s", [self getVideoLength:sourceURL]]);
NSLog(@"%@", [NSString stringWithFormat:@"%.2f kb", [self getFileSize:[sourceURL path]]]);
NSURL *newVideoUrl ; //一般.mp4
NSDateFormatter *formater = [[NSDateFormatter alloc] init];//用时间给文件全名，以免重复，在测试的时候其实可以判断文件是否存在若存在，则删除，重新生成文件即可
[formater setDateFormat:@"yyyy-MM-dd-HH:mm:ss"];
newVideoUrl = [NSURL fileURLWithPath:[NSHomeDirectory() stringByAppendingFormat:@"/Documents/output-%@.mp4", [formater stringFromDate:[NSDate date]]]] ;//这个是保存在app自己的沙盒路径里，后面可以选择是否在上传后删除掉。我建议删除掉，免得占空间。
_fileName = [NSString stringWithFormat:@"output-%@.mp4", [formater stringFromDate:[NSDate date]]];
NSURL * url = [info objectForKey:UIImagePickerControllerMediaURL];
NSString * urlStr = [url path];
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(urlStr)) {
//保存视频到相簿，注意也可以使用ALAssetsLibrary来保存
UISaveVideoAtPathToSavedPhotosAlbum(urlStr, self, @selector(video:didFinishSavingWithError:contextInfo:), nil);
}
[picker dismissViewControllerAnimated:YES completion:nil];
[self convertVideoQuailtyWithInputURL:sourceURL outputURL:newVideoUrl completeHandler:nil];
}
#pragma mark - 自定义方法
- (void)video:(NSString *)videoPath didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{
if (error) {
NSLog(@"保存视频过程中发生错误，错误信息:%@",error.localizedDescription);
} else {
NSLog(@"视频保存成功");
_videoUrl = videoPath;
NSURL * url = [NSURL fileURLWithPath:videoPath];
// self.dateTimeLab.text = [LYWRegex getCurrentTimes];
//获取视频第一帧
// [self.showBtn setBackgroundImage:[LYWRegex thumbnailImageForVideo:url atTime:1] forState:UIControlStateNormal];
}
}
压缩视频并上传给服务器 使用AFN
#pragma mark - 压缩视频

outputURL:(NSURL*)outputURL
completeHandler:(void (^)(AVAssetExportSession*))handler

AVAssetExportSession *exportSession = [[AVAssetExportSession alloc] initWithAsset:avAsset presetName:AVAssetExportPresetMediumQuality];
// NSLog(resultPath);
exportSession.outputURL = outputURL;
exportSession.outputFileType = AVFileTypeMPEG4;
exportSession.shouldOptimizeForNetworkUse= YES;
[exportSession exportAsynchronouslyWithCompletionHandler:^(void)

// [self alertUploadVideo:outputURL];
break;

NSLog(@"AVAssetExportSessionStatusFailed");
break;
}
}];
}
-(void)alertUploadVideo:(NSURL*)URL{

Demo把视频上传到服务器的代码注释掉了
