UIButton上的標題被截斷

Question

我已經將UIButton設置為導航欄的titleView。 但是，無論按鈕有多寬，標題似乎都被截斷了。 為什么？

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setTitle:[[NSDate date] stringWithNSDateFormatterMediumStyle] forState:UIControlStateNormal];
[button setFrame:CGRectMake(0, 0, 150, 40)];
self.navigationItem.titleView = button;

Answer 1

 [button setFrame:CGRectMake(0, 0, 250, 40)];  // are you sure your button is wide enough?
