然后，我导出一个xcode工程（版本：unity4.2.1、xcode5）。。。
如图：
这是unity导出来的xcode工程的目录结构。
接下来：
第一步：选择UnityAppController.mm这个文件打开。
并在int OpenEAGL_UnityCallback(UIWindow** window, int* screenWidth, int* screenHeight, int* openglesVersion)
这个方法里面的
return true;之前加入
//创建一个全屏幕的window
CGRect rect=CGRectMake(0, 0, *screenWidth, *screenHeight);
*window=[[UIWindow alloc] initWithFrame:rect];
[*window makeKeyAndVisible];
GLView * view=[[GLView alloc] initWithFrame:rect];
[*window addSubview:view];
[view release];
MyViewController *myView=[[MyViewController alloc] init];
[*window addSubview:myView.view];
[myView release];
其中：MyViewController是导出工程后，手动新建的类，目的是，在这个ViewController种控制u3d模型的旋转、移动等动作。
第二步：创建MyViewController并添加按钮，启动u3d
- (void)viewDidLoad {
[super viewDidLoad];
//创建label视图
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];
//设置显示内容
label.text = @"雨松MOMO的程序世界";
//设置背景颜色
label.backgroundColor = [UIColor blueColor];
//设置文字颜色
label.textColor = [UIColor whiteColor];
//设置显示位置居中
label.textAlignment = UITextAlignmentCenter;
//设置字体大小
label.font = [UIFont fontWithName:[[UIFont familyNames] objectAtIndex:10] size:20];
//创建按钮
UIButton *button0 = [UIButton buttonWithType:1];
//设置按钮范围
button0.frame = CGRectMake(0, 40, 100, 30);
//设置按钮显示内容
[button0 setTitle:@"矩形左旋转" forState:UIControlStateNormal];
//设置按钮改变后 绑定响应方法
[button0 addTarget:self action:@selector(LeftButtonPressed) forControlEvents:UIControlEventTouchUpInside];
//创建按钮
UIButton *button1 = [UIButton buttonWithType:1];
//设置按钮范围
button1.frame = CGRectMake(0, 100, 100, 30);
//设置按钮显示内容
[button1 setTitle:@"矩形右旋转" forState:UIControlStateNormal];
//设置按钮改变后 绑定响应方法
[button1 addTarget:self action:@selector(RightButtonPressed) forControlEvents:UIControlEventTouchUpInside];
//创建按钮
UIButton *button2 = [UIButton buttonWithType:1];
//设置按钮范围
button2.frame = CGRectMake(0, 160, 100, 30);
//设置按钮显示内容
[button2 setTitle:@"矩形上旋转" forState:UIControlStateNormal];
//设置按钮改变后 绑定响应方法
[button2 addTarget:self action:@selector(UpButtonPressed) forControlEvents:UIControlEventTouchUpInside];
//创建按钮
UIButton *button3 = [UIButton buttonWithType:1];
//设置按钮范围
button3.frame = CGRectMake(0, 220, 100, 30);
//设置按钮显示内容
[button3 setTitle:@"矩形下旋转" forState:UIControlStateNormal];
//设置按钮改变后 绑定响应方法
[button3 addTarget:self action:@selector(DownButtonPressed) forControlEvents:UIControlEventTouchUpInside];
//向view添加
[self.view addSubview:label];
[self.view addSubview:button0];
[self.view addSubview:button1];
[self.view addSubview:button2];
[self.view addSubview:button3];
}
//向左按钮
-(void)LeftButtonPressed{
UnitySendMessage("Cube","MoveLeft","");
}
//向右按钮
-(void)RightButtonPressed{
UnitySendMessage("Cube","MoveRight","");
}
//向上按钮
-(void)UpButtonPressed{
UnitySendMessage("Cube","MoveUp","");
}
//向下按钮
-(void)DownButtonPressed{
UnitySendMessage("Cube","MoveDown","");
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc. that aren't in use.
}
- (void)viewDidUnload {
[super viewDidUnload];
}
- (void)dealloc {
[super dealloc];
}
第三步：修改Bundle Identifier，进行真机测试
到此，代码部分全部搞定。接下来是真机，等待运行...
艰难的运行中，大约两分钟...
u3d的开机画面出来了，刷一下，进入到了你添加的界面，里面有几个按钮，分别是控制模型旋转的。
此时，看上去一切都很顺路，轻轻的，点一下，其中一个按钮。。。。问题出了。。崩溃。。。
悲剧的崩溃。。。
控制台输出了一大堆错误。
错误如下：
