Sphereo构建在Xcode4上失败

我正在尝试为“

Sphero

”创建IOS应用程序，我想测试

HelloWorld

示例，但是在创建新项目后，我单击了build，但它失败了，我遇到了4个问题：

1） 使用af未声明的标识符“

viewDidLoad

”：

 -(void)viewDidLoad {

2） 消息发送表达式开头缺少

“[”

这在下面的代码行中，xcode希望在第二个“选择器”前面加上[in]

3） 错误的接收器类型

'SEL'

（与上述同一行）

4） 预期对外申报：

最后一个花括号出现错误

-(void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
-(void)viewDidLoad {
    [super viewDidLoad];

    /*Register for application lifecycle notifications so we known when to connect and disconnect from the robot*/
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appDidBecomeActive:) name:UIApplicationDidBecomeActiveNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appWillResignActive:) name:UIApplicationWillResignActiveNotification object:nil];

    /*Only start the blinking loop when the view loads*/
    robotOnline = NO;

    calibrateHandler = [[RUICalibrateGestureHandler alloc] initWithView:self.view];
}

}

---

用这个替换你的代码

-(void)viewDidLoad {
    [super viewDidLoad];

    /*Register for application lifecycle notifications so we known when to connect and disconnect from the robot*/
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appDidBecomeActive:) name:UIApplicationDidBecomeActiveNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appWillResignActive:) name:UIApplicationWillResignActiveNotification object:nil];

    /*Only start the blinking loop when the view loads*/
    robotOnline = NO;

    calibrateHandler = [[RUICalibrateGestureHandler alloc] initWithView:self.view];
}

试试这个

-(void)viewDidLoad {
    [super viewDidLoad];

    /*Register for application lifecycle notifications so we known when to connect and disconnect from the robot*/
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appDidBecomeActive:) name:UIApplicationDidBecomeActiveNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appWillResignActive:) name:UIApplicationWillResignActiveNotification object:nil];

    /*Only start the blinking loop when the view loads*/
    robotOnline = NO;

    calibrateHandler = [[RUICalibrateGestureHandler alloc] initWithView:self.view];
}
