更改uinavigationcontroller上后退按钮的字体 [英] change font of back button on uinavigationcontroller

问题描述

  [[UIBarButtonItem外观] 
我试图改变我的后退按钮上的文本的字体颜色UINavigationControllerBar ] setTitleColor：[UIColor redColor] forState：UIControlStateNormal]; 
  

给我这个错误：[_UIBarItemAppearance setTitleColor：forState：]：无法识别的选择器发送到实例0x69aeb70' / p>

有什么帮助吗？谢谢！

解决方案

使用这个，而不是在iOS 5中可用的默认功能

  UIBarButtonItem * backbutton = [[UIBarButtonItem alloc] initWithTitle：@backstyle：UIBarButtonItemStyleBordered target：nil action：nil]; 
 
 [backbutton setTitleTextAttributes：[NSDictionary dictionaryWithObjectsAndKeys：
 [UIColor blackColor]，UITextAttributeTextColor，[UIFont fontWithName：TEXTFONT size：16.0f]，UITextAttributeFont，
 nil] forState：UIControlStateNormal] ; 
  

I'm trying to change the font color of the text on my back button in my UINavigationControllerBar

    [[UIBarButtonItem appearance] setTitleColor:[UIColor redColor] forState:UIControlStateNormal];

gives me this error: [_UIBarItemAppearance setTitleColor:forState:]: unrecognized selector sent to instance 0x69aeb70'

Any help? Thanks!

解决方案

Use this instead, default function available in ios 5

UIBarButtonItem *backbutton =  [[UIBarButtonItem alloc] initWithTitle:@"back" style:UIBarButtonItemStyleBordered target:nil action:nil];    

    [backbutton setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                   [UIColor blackColor],UITextAttributeTextColor,[UIFont fontWithName:TEXTFONT size:16.0f],UITextAttributeFont,
                                                   nil] forState:UIControlStateNormal];
