Answer 1

您不能更改title的字體。請改爲使用您自己的自定義創建UILabel，並將其指定爲navigationItem的titleView。

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

Answer 2

嘗試設置的自定義標籤標題標籤：

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];
