如何修改ios的导航条上面的文字颜色和大小等

方法一:

利用titleTextAttributes这个属性,它上面可以修改字体的颜色,大小阴影等.如下:

[objc] view
plaincopy

NSDictionary *dict=[NSDictionary dictionaryWithObjects:

[NSArray arrayWithObjects:[UIColor whiteColor],[UIFont boldSystemFontOfSize:17],[UIColor clearColor],nil]

forKeys:

[NSArray arrayWithObjects:UITextAttributeTextColor,UITextAttributeFont,UITextAttributeTextShadowColor,nil]];

self.navigationController.navigationBar.titleTextAttributes=dict;

方法二:
利用self.navigationItem.titleView,使用一个自定义的label来替换这个view,达到自定义导航标题的效果.

[objc] view
plaincopy

UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 180, 20)];

label.text=self.title;

label.backgroundColor=[UIColor clearColor];

label.font=[UIFont boldSystemFontOfSize:17];

label.textAlignment=UITextAlignmentCenter;

label.textColor=[UIColor whiteColor];

//self.title=filename;

self.navigationItem.titleView=label;
