1.添加代理UIImagePickerControllerDelegate
2.设置点击跳转事件
- (IBAction)picButton:(UIButton *)sender {
NSLog(@"我的相册");
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]){
//a.初始化相册拾取器
UIImagePickerController *controller = [[UIImagePickerController alloc] init];
//b.设置代理
controller.delegate = self;
//c.设置资源：
/**
UIImagePickerControllerSourceTypePhotoLibrary,相册
UIImagePickerControllerSourceTypeCamera,相机
UIImagePickerControllerSourceTypeSavedPhotosAlbum,照片库
*/
controller.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
//d.随便给他一个转场动画
controller.modalTransitionStyle=UIModalTransitionStyleFlipHorizontal;
[self presentViewController:controller animated:YES completion:NULL];
}else{
UIAlertView * alert = [[UIAlertView alloc]initWithTitle:@"提示" message:@"设备不支持访问相册，请在设置->隐私->照片中进行设置！" delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
[alert show];
}
}
3.获取图片
#pragma mark-> imagePickerController delegate
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
//a.获取选择的图片
UIImage *image = info[UIImagePickerControllerOriginalImage];
self.imageView.image = image;
}
