無法更改textview中的文本

Question

我有問題，無法在UITextView中設置新文本。我已經在界面生成器中將IBOutlet連接到textView。這裏是我的代碼

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    self.title = @"Detail"; 
    [self setupTextView]; 

} 

- (void) setupTextView 
{ 
    self.textDescription = [[[UITextView alloc] init] autorelease]; 
    NSString *foo = @"blah blah blah"; 
    textDescription.text = foo; //I try this and it didn't work 
    //here didn't work too. 
    //textDescription.text = [textDescription.text stringByAppendingString:foo]; 

    /*Here is something for dynamic textview*/ 
    CGRect frame; 
    frame = textDescription.frame; 
    frame.size.height = [textDescription contentSize].height; 
    textDescription.frame = frame; 
    /**/ 
} 

感謝您阿努幫助:)

self.textDescription = [[[UITextView alloc] init] autorelease]; 

我想這就是問題所在。如果textDescription是IBOutlet，則不需要分配它。只要刪除這個分配。
