系统自带的，就是来做个记录。重点是自带对视频简单的裁剪操作，很实用
不多说直接.m 文件中的代码吧
#import "ViewController.h" @interface ViewController ()<UIImagePickerControllerDelegate,UINavigationControllerDelegate> @property (strong, nonatomic) UIImagePickerController *imagePickerController; @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor whiteColor]; UIButton* pickVideoBtn = [UIButton buttonWithType:UIButtonTypeCustom]; [pickVideoBtn setFrame:CGRectMake(0, 0, 100, 50)]; [pickVideoBtn setCenter:CGPointMake(self.view.frame.size.width/2, 100)]; [pickVideoBtn setTitle:@"选择视频" forState:UIControlStateNormal]; [pickVideoBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; [pickVideoBtn addTarget:self action:@selector(PickVideo) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:pickVideoBtn]; } //视频 -(void)PickVideo
