ios - 在 ios 7 中如何增加 UINavigationbar 的大小

Question

使用 Storyboard创建导航栏。现在在 iOS 7 中，我面临着增加导航栏高度的挑战。

UINavigationBar *navBar = [[self navigationController] navigationBar];

[navBar setFrame:CGRectMake(0, 100, 1024, 200)];

Answer 1

UIFont *font = [UIFont fontWithName:@"fontName" size:YourFloatSize];
CGSize titleSize = [title sizeWithFont:font];
UILabel *titleLable = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, titleSize.width, titleSize.height)];
titleLable.text = title;
titleLable.textAlignment = NSTextAlignmentCenter;
titleLable.backgroundColor = [UIColor clearColor];
titleLable.textColor = [UIColor anyColorYouWant];

titleLable.font = font;
self.navigationItem.titleView = titleLable;
