1.新增framework：MobileCoreServices

2.頭：#import <MobileCoreServices/MobileCoreServices.h>

大致程式碼：

 

UIImagePickerController *imagePicker=[[UIImagePickerController alloc]init];;//例項並初始化；
    imagePicker.delegate=self;//影象選擇器委託設定為
    //選取本地movie

        imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        imagePicker.mediaTypes =  [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
        [self presentViewController:imagePicker animated:YES completion:nil];

    
    //選取本地圖片
        imagePicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
        imagePicker.mediaTypes=[[NSArray alloc] initWithObjects: (NSString *) kUTTypeImage, nil];
         [[UIApplication sharedApplication] setStatusBarHidden:YES];//隱藏狀態列；
        [self presentViewController:imagePicker animated:YES completion:nil];


    //相機
        if ([UIImagePickerController isSourceTypeAvailable:   UIImagePickerControllerSourceTypeCamera]){         

             imagePicker.sourceType=UIImagePickerControllerSourceTypeCamera;
             imagePicker.mediaTypes=[[NSArray alloc] initWithObjects: (NSString *) kUTTypeImage, nil];
             // [[UIApplication sharedApplication] setStatusBarHidden:YES];//隱藏狀態列；
             [self presentViewController:imagePicker animated:YES completion:nil];
        }else{
            NSLog(@"照相機不可用");
        }
       
   //錄影機
        if ([UIImagePickerController isSourceTypeAvailable:   UIImagePickerControllerSourceTypeCamera]){                

            imagePicker.sourceType=UIImagePickerControllerSourceTypeCamera;
            imagePicker.mediaTypes=[[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
             [[UIApplication sharedApplication] setStatusBarHidden:YES];//隱藏狀態列；
            [self presentViewController:imagePicker animated:YES completion:nil];
        }else{
            NSLog(@"照相機不可用");
        }
