titleTextAttributes iOS 7中的UIAppearance字体 [英] titleTextAttributes UIAppearance font in iOS 7

问题描述

我正在使用UIAppearance将字体应用于UINavigationBar和UIBarButtonItem，我遇到了问题。我运行了这段代码：

I am using UIAppearance to apply fonts to UINavigationBar and UIBarButtonItem and I am having problems. I ran this code:

[[UIBarButtonItem appearanceWhenContainedIn:[UIToolbar class], nil] 
setTitleTextAttributes:
@{NSFontAttributeName : [UIFont fontWithName:@"My_Font" size:17.0]} 
forState:UIControlStateNormal];

NSLog(@"%@", [[UIBarButtonItem appearanceWhenContainedIn:
[UIToolbar class], nil] titleTextAttributesForState:UIControlStateNormal]);

并且iOS 7上的日志结果是：

and the result of that log on iOS 7 is:

(null)

结果如何iOS 6是：

Where the result in iOS 6 is:

{
    NSFont = "<UICFFont: 0x1d897a80> font-family: \"My_Font\"; font-weight: normal; font-style: normal; font-size: 17px";
}

我在iOS 7文档中找不到任何表明这一点的内容应该不行，有其他人有这个问题吗？

I can't find anything in the iOS 7 docs that would indicate that this shouldn't work, has anyone else had this problem?

Edit 1

我实际上已经使用 [UINavigationBar外观] 问题是我将点大小设置为0才能拥有字体设置为默认的navbar / barButtonItem大小，如 NSString UIKit Additions Reference 但这显然不再适用于iOS 7.相反，将磅值设置为0将返回系统字体。

I actually have gotten this to work with [UINavigationBar appearance] the problem was that I was setting the point size to 0 in order to have the font be set to the default navbar/barButtonItem size as described in the NSString UIKit Additions Reference but this apparently no longer works in iOS 7. Instead, setting the point size to 0 will return the system font.

我仍然无法将 titleTextAttributes 设置为

[UIBarButtonItem appearanceWhenContaintedIn ：[UIToolbar class]，nil]]

推荐答案

NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:[UIFont 
    fontWithName:@"YOURFONT" size:14], NSFontAttributeName, 
    [UIColor whiteColor], NSForegroundColorAttributeName, nil];

[[UINavigationBar appearance] setTitleTextAttributes:attributes];

关键是使用NSFontAttributeName等等。我假设他们正在转向使用NS品种进行64位兼容。上面的代码适用于我的iOS7设备。

The key is to use NSFontAttributeName and so forth. I assume they are moving over to using the NS variety for 64-bit compatibility. The above code worked on my iOS7 device.
