ios - 如何更改 UISegmentedControl 上文本的字体大小？

Question

以下是初始化我的 UISegmentedControl 的代码。

- (void)initializeToolButtons
{
    NSArray *buttonTitles = [NSArray arrayWithObjects:@"ANNEXET", @"HOVET", @"GLOBEN", "ALL", nil];

    toolbuttons = [[UISegmentedControl alloc] initWithItems:buttonTitles];
    toolbuttons.segmentedControlStyle = UISegmentedControlStyleBar;
    toolbuttons.tintColor = [UIColor darkGrayColor];
    toolbuttons.backgroundColor = [UIColor blackColor];     
    toolbuttons.frame = CGRectMake(0, 0, 320, 30);

    [toolbuttons addTarget:self action:@selector(toolButtonsAction) forControlEvents:UIControlEventValueChanged];

    [self.view addSubview:toolbuttons];
}

如何减小 UISegmentedControl 上每个项目的字体大小？

注意: toolButtons 已在全局声明。

非常简单:

UIFont *Boldfont = [UIFont boldSystemFontOfSize:16.0f];
    NSDictionary *attributes = [NSDictionary dictionaryWithObject:Boldfont forKey:UITextAttributeFont];
    [segment setTitleTextAttributes:attributes forState:UIControlStateNormal];
