標題UIButton截斷

Question

我已經設置了一個UIButton作爲我的導航欄的titleView。但是，無論按鈕的寬度如何，標題似乎都會被截斷。爲什麼？

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?
