Iphone：标签文本udates值但不显示在视图中

Question

我m working on a part of code where a label text should change value after getting a new value from a singleton class. Seems simple enough, and after testing the value it actually changes aswell, but its not updated in the view. In the view it stays the same as before. I尝试了 - （void）viewDidLoad和-(void)viewWillAppear:(BOOL)animated中的代码，但结果相同..有什么想法吗？

以下是我的代码：

- (void)viewDidLoad {
//get the new status value
sharedBarCodeValue = [BarcodeValues sharedBarCodeValues];
if([[sharedBarCodeValue storeBarCodeValue] isEqualToString:@"123456"])
{
    [statusText setText:@"This is a new status text"];
}
//for testing, output status text
NSLog(@"status: %@", statusText.text);
[super viewDidLoad];

}

编辑：哦，我应该提一下，我已经实现了一个导航控制器，当从堆栈中弹出2.级视图并返回到根视图时，该值应该会改变。

确保您的statusText插座已正确连接到您的IB对象。
