iphone - 无法更改 TextView 中的文本

Question

我无法在 UITextView 中设置新文本。我已经在界面生成器中将 IBOutlet 链接到 textView。这是我的代码

- (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;
     /**/
}

感谢您的帮助:)

Answer 1

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

我认为这就是问题所在。如果 textDescription 是 IBOutlet，则无需分配它。只需删除此分配即可。
