Unity调IOS相册

相对来讲，IOS 的实现比Android要简单得多，可是重点是IOS很差测试，要macOS，要相应版本的xcode，建议你们不要搞虚拟机了，我搞了两天，头发一把一把的拖，最后直接放弃

找公司的IOS配合或者看谁有mac的借来用用都比虚拟机强，话很少说，言归正传

Unity调用IOS 的相册只须要在Unity的Plugins-IOS文件夹里放两个文本文件，而后改后缀，一个改为.h  一个改为.m   名字同样不要紧，咱后缀不同，一个是C++  一个OC

 

 

 

.h是头文件 至关于引入 接口 直接复制一下代码

1 #import<QuartzCore/CADisplayLink.h>
2 @interface IOSCameraController : UIViewController<UIImagePickerControllerDelegate,UINavigationControllerDelegate,UIPopoverPresentationControllerDelegate>
3 @end

.m是实现文件，功能在这写

 1 #import "IOSCameraController.h"
 2 
 3 @implementation IOSCameraController  4 -(void)OpenCamera:(UIImagePickerControllerSourceType)type{  5     //建立UIImagePickerController实例
 6     UIImagePickerController *picker;  7     picker= [[UIImagePickerController alloc]init];  8     //设置代理
 9     picker.delegate = self;  10     //是否容许编辑 (默认为NO)
 11     picker.allowsEditing = YES;  12     //设置照片的来源
 13     picker.sourceType = type;  14     //展现选取照片控制器
 15     if (picker.sourceType == UIImagePickerControllerSourceTypePhotoLibrary &&[[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {  16         picker.modalPresentationStyle = UIModalPresentationPopover;  17         UIPopoverPresentationController *popover = picker.popoverPresentationController;  18         //picker.preferredContentSize = [UIScreen mainScreen].bounds.size;
 19         popover.delegate = self;  20         popover.sourceRect = CGRectMake(0, 0, 0, 0);  21         popover.sourceView = self.view;  22         popover.permittedArrowDirections = UIPopoverArrowDirectionAny;  23  [self presentViewController:picker animated:YES completion:nil];  24     } else {  25         [self presentViewController:picker animated:YES completion:^{}];  26  }  27    
 28 }  29 -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{  30     [picker dismissViewControllerAnimated:YES completion:^{}];  31     UIImage *image = [info objectForKey:@"UIImagePickerControllerEditedImage"];  32     if (image == nil) {  33         image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];  34  }  35     //图片旋转
 36     if (image.imageOrientation != UIImageOrientationUp) {  37     //图片旋转

IOS就是这么简单粗暴

而后测试脚本，重点看怎么调用

 1 using System.Collections;  2 using System.Collections.Generic;  3 using UnityEngine;  4 using UnityEngine.UI;  5 using System.IO;  6 using System.Runtime.InteropServices;  7 using UnityEngine.SceneManagement;  8 
 9 public class TestWWWTex : MonoBehaviour { 10 
11     [SerializeField] private Button _openCamera; //打开相机按钮
12     [SerializeField] private Button _openAlbum; //打开相册按钮
13     [SerializeField] private RawImage _image; //用于显示的图片 14     //引入在oc中定义的那两个方法
15     [DllImport("__Internal")] 16     private static extern void IOS_OpenCamera(); 17     [DllImport("__Internal")] 18     private static extern void IOS_OpenAlbum(); 19 
20     void Awake() 21  { 22         //为两个button添加点击事件
23  _openCamera.onClick.AddListener(IOS_OpenCamera); 24  _openAlbum.onClick.AddListener(IOS_OpenAlbum); 25  } 26 
27     //ios回调unity的函数
28     void Message(string filenName) 29  { 30         31         
32         string filePath = Application.persistentDataPath + "/" + filenName; 33         34        
35  TestFileFunc(filePath); 36  } 37 
38     void TestFileFunc(string path) 39  { 40         FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read); 41         fileStream.Seek(0, SeekOrigin.Begin); 42         byte[] bye = new byte[fileStream.Length]; 43         fileStream.Read(bye, 0, bye.Length); 44  fileStream.Close(); 45 
46         Texture2D texture2D = new Texture2D(240, 144); 47  texture2D.LoadImage(bye); 48 
49         _image.texture = texture2D; 50 
51  } 52 }

这里说一下，www加载会找不到照片，http加载，xcode会报错，看不懂报了什么错，好像是没给权限，xcode建议用https，我就懒得搞了，直接用文件流加载吧

接下来就是打xcode工程 在xcode里找到info.plist文件，加一个相册权限，以后就能真机测试了
