在进行项目的过程中,我们往往会遇到各种各样的自定义颜色和字体,下面提供一种修改系统自带的TabBarItem的字体和颜色的方法,希望能帮到大家:

[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], UITextAttributeTextColor,
nil] forState:UIControlStateNormal];
UIColor *titleHighlightedColor = [UIColor greenColor];
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
titleHighlightedColor, UITextAttributeTextColor,
nil] forState:UIControlStateSelected];

上面是正常的,下面是选中的!

BarButtonItem的title的字体大小和颜色:

[button1 setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:14],NSForegroundColorAttributeName:[UIColor blueColor]} forState:UIControlStateNormal];
[button1 setTitle:@"排单币转账记录"];
[button1 setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:]} forState:UIControlStateNormal];
self.navigationItem.rightBarButtonItem = button1;

这样也可以修改大小!

UIBarButtonItem的添加返回背景图片和点击方法:

UIBarButtonItem *button = [[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"backBarButton"] style:(UIBarButtonItemStyleDone) target:self action:@selector(backAction)];
self.navigationItem.leftBarButtonItem = button;

以上只是修改系统的,可能有些方法我们遇不到用的机会!如果是自定义的话,就不用这么麻烦了!
