如何更改UIButton字體iOS6

您好，我與titleLabel屬性有問題。當我想改變它。這些變化並沒有發生。這是我的代碼：如何更改UIButton字體iOS6

UIButton *menuItemButton = [[UIButton alloc] initWithFrame:CGRectMake(x, y, 290.0, 35.0)]; 
[menuItemButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal]; 
[menuItemButton setTitleColor:[UIColor grayColor] forState:UIControlStateHighlighted]; 
       menuItemButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft; 
[menuItemButton setContentEdgeInsets:UIEdgeInsetsMake(0, 11.0, 0, 0)]; 
[menuItemButton setTitle:(NSString *)[itemParams objectForKey:@"Name"] forState:UIControlStateNormal]; 
[menuItemButton setBackgroundImage:menuItemImage forState:UIControlStateNormal]; 
[menuItemButton setTag:idx]; 
[[menuItemButton titleLabel] setFont:[UIFont fontWithName:@"Vardana" size:5]]; 
[menuItemButton addTarget:self action:@selector(menuItemClicked:) forControlEvents:UIControlEventTouchUpInside];

，這是不工作：

[[menuItemButton titleLabel] setFont:[UIFont fontWithName:@"Vardana" size:15]];

我也嘗試：

[menuItemButton.titleLabel setFont:[UIFont fontWithName:@"Vardana" size:15]]; 
menuItemButton.titleLabel.font = [UIFont fontWithName:@"Vardana" size:15];

titleLabel的其它性能也沒有爲前工作。對齊和顏色。

所有thigs我寫viewDidLoad後[super viewDidLoad];
