1.js脚本（添加到ARCamera上）
#pragma strict function Start () {} function Update () {} function ScreenImage(){ Application.CaptureScreenshot("Screenshot.png"); }
2.添加button
UIButton *button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [button1 setFrame:CGRectMake(0, 0, 30, 30)]; [button1 addTarget:self action:@selector(ScreenImage) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:button1];
3.响应函数
-(void)ScreenImage{ ///调取脚本函数 UnitySendMessage("ARCamera","ScreenImage",""); //保存到相册 NSFileManager *fileManager = [NSFileManager defaultManager]; NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *filePath2 = [documentsDirectory stringByAppendingPathComponent:@"Screenshot.png"]; UIImage *image = [UIImage imageWithContentsOfFile:filePath2]; UIImageWriteToSavedPhotosAlbum(image,nil, nil, nil);//保存 }
