CocoaPods导入三方库

end

导入RecordUI---Demo下载

视频录制库

.pch文件导入#import "JHRecord.h"

看一下.h头文件详情

控制器加载录制View和上传View

@property (strong, nonatomic) JHRecordView                *recordView;
@property (strong, nonatomic) JHUploadView                *uploadView;

__strong typeof(self) weakSelf = self;//避循环引用
[self.view addSubview:weakSelf.uploadView];
[self.view addSubview:weakSelf.recordView];

/**
 *  录制View
 */
-(JHRecordView*)recordView{
    if (!_recordView) {
        _recordView = [[JHRecordView alloc]initWithFrame:CGRectMake(0, 20, WIDTH, HEIGHT-20)];
        [_recordView.recordViewSubject subscribeNext:^(NSDictionary *dict) {
            NSString *btnType = [dict objectForKey:@"btnType"];
            if ([btnType isEqualToString:@"相册"])     {
                self.picker.mediaTypes = @[@"public.movie"];//@[(NSString *)kUTTypeMovie];// 仅视频
                self.picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
                [self presentViewController:self.picker animated:YES completion:nil];
            }
            else if ([btnType isEqualToString:@"上传"]){
                [ViewUtil rollAnimation:self.view];
                
                self.uploadView.coverImage = self.recordView.recordEngine.originVideoCover;
                
                [self.view bringSubviewToFront:self.uploadView];
            }
        }];
    }
    return _recordView;
}

/**
 *  上传View
 */
-(JHUploadView*)uploadView{
    if (!_uploadView) {
        _uploadView = [[JHUploadView alloc]initWithFrame:CGRectMake(0, 20, WIDTH, HEIGHT-20)];
        [_uploadView.uploadViewSubject subscribeNext:^(NSDictionary *dict) {
            NSString *btnType = [dict objectForKey:@"btnType"];
            if ([btnType isEqualToString:@"相册"])     {
                self.picker.mediaTypes = @[@"public.image"];// 仅图片
                self.picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
                NSArray *types = [UIImagePickerController availableMediaTypesForSourceType:self.picker.sourceType];
                NSLog(@"所有的文件类型:%@",types);
                [self presentViewController:self.picker animated:YES completion:nil];
            }
            else if ([btnType isEqualToString:@"上传"]){
                //[TipUtil tipSuccess:@"主人，往哪里传呀？"   DismissAfter:0.6];
            }
            else if ([btnType isEqualToString:@"取消"]){
                [ViewUtil rollAnimation:self.view];
                
                [self.view bringSubviewToFront:self.recordView];
            }
        }];
    }
    return _uploadView;
}

录制选视频，上传选封面，两个功能在控制器合二为一

1、导入相册系统库

#import <MobileCoreServices/MobileCoreServices.h>

2、声明协议

<UIImagePickerControllerDelegate,UINavigationControllerDelegate>

3、懒加载UIImagePickerController

// 相册控制器
@property (strong, nonatomic) UIImagePickerController     *picker;
/**
 *  本地相册视频库
 */
- (UIImagePickerController *)picker {
    if (_picker == nil) {
        _picker = [[UIImagePickerController alloc] init];
        _picker.delegate = self;
        _picker.allowsEditing = NO;
        
        
        
        [[self rac_signalForSelector:@selector(imagePickerControllerDidCancel:)] subscribeNext:^(id x) {
            [self.picker dismissViewControllerAnimated:YES completion:nil];
        }];
        
        [[self rac_signalForSelector:@selector(imagePickerController:didFinishPickingMediaWithInfo:)] subscribeNext:^(RACTuple *tuple) {
            NSDictionary *infoDict = tuple.second;
            NSLog(@"选择的结果:%@",infoDict);
            NSString *mediaType = [infoDict objectForKey: UIImagePickerControllerMediaType];
            if ([mediaType isEqualToString:@"public.movie"]) {
                // 视频
                NSURL *videoUrl=(NSURL*)[infoDict objectForKey:UIImagePickerControllerMediaURL];
                NSString *moviePath = [videoUrl path];
                [[NSFileManager defaultManager] copyItemAtPath:moviePath toPath:[self.recordView.recordEngine uploadPath] error:nil];
                [self.recordView.recordEngine movieToImageHandler:^(UIImage *movieImage) {
                    NSLog(@"封面:\n%@",movieImage);
                }];
                [self.recordView startVideoPlayer:[NSURL fileURLWithPath:self.recordView.recordEngine.videoPath]];
            }
            else if ([mediaType isEqualToString:@"public.image"]) {
                // 封面
                UIImage *selectedImage = [infoDict objectForKey:UIImagePickerControllerOriginalImage];
                if (selectedImage) self.uploadView.coverImage = selectedImage;
            }
            [_picker dismissViewControllerAnimated:YES completion:nil];
        }];
    }
    return _picker;
}

4、中文模式

中文简体

5、导入CocoaPods如果报错，Build Settings搜索weak设置Weak References·····为YES

允许引用计数
