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];
