Answer 1

尝试为标题标签设置自定义标签：

    self.title = @"Cook Great Indian Recipes";
    CGRect frame = CGRectMake(0, 0, [self.title sizeWithFont:[UIFont boldSystemFontOfSize:20.0]].width, 44);
    UILabel *label = [[UILabel alloc] initWithFrame:frame];
    label.backgroundColor = [UIColor clearColor];
    label.font = [UIFont boldSystemFontOfSize:17.0];
    label.textAlignment = UITextAlignmentCenter;
    self.navigationItem.titleView = label;
    label.text = self.title;
    [label release];

Answer 2

您无法更改title的字体。 而是使用您自己的自定义创建UILabel并将其指定为navigationItem的 titleView 。

UILabel *titleLbl = [[UILabel alloc] init];
label.frame = CGRectMake(...
label.font = [UIFont ...
// And the other things
self.navigationItem.titleView = titleLbl;
[titleLbl release];
