问题描述

我想要在我的 NavigationBar 中使用这样的 UIBarButton 项，并且

I want a UIBarButton Item like this in my NavigationBar and

像这样的普通 UIButton

Normal UIButton like this

我已经尝试过使用这些链接问题1 问题 2 问题 3 但没有得到输出.

I already tried using these links Question 1 Question 2 Question 3 but didn't got the output.

我需要将那个 FontAwesome 图标附加到按钮标题文本中.

My need is to append that FontAwesome icon with the button title text.

有人可以帮忙吗?

我的代码是:

NSString *icon = [NSString fontAwesomeIconStringForIconIdentifier:@"fa-folder-open"];

NSString *locationString = [NSString stringWithFormat:@"%@ %@", icon, @"Change"];

NSMutableAttributedString *astring = [[NSMutableAttributedString alloc] initWithString:locationString];

[astring addAttribute:NSFontAttributeName
                value:[UIFont iconicFontOfSize:20]
                range:NSMakeRange(0,1)]; // The first character

changeFolderButton.titleLabel.attributedText = astring;

推荐答案

如果FontAwesome图标的code是"&#xf007"，则设置text为@"U0000f007" 改成标题.

If code of FontAwesome Icon is "&#xf007", then set text to @"U0000f007" into Title.

UIButton 使用以下代码:-

myBtn.titleLabel.font =[UIFont fontWithName:@"FontAwesome" size:20.0];
[myBtn setTitle:@"U0000f007" forState:UIControlStateNormal]];

UIBarButton 使用以下代码:-

[self.barButton setTitleTextAttributes:@{
              NSFontAttributeName: [UIFont fontWithName:@"FontAwesome" size:24.0],
              NSForegroundColorAttributeName: self.view.tintColor
                                     } forState:UIControlStateNormal]; 
[self.barButton setTitle:@"U0000f007"]];

如果您想在字符串中附加图标，请使用以下代码:-

If you want to append your string with icon then use following code:-

NSString * myString = @"U0000f007 Change";
NSMutableAttributedString *astring = [[NSMutableAttributedString alloc] initWithString:myString];
[astring addAttribute:NSFontAttributeName
                value:[UIFont fontWithName:@"FontAwesome" size:22.0]
                range:NSMakeRange(0,1)]; //If Icon is on starting position
[myBtn setAttributedTitle:astring forState:UIControlStateNormal];

希望，这就是您要找的.任何问题都可以回复我.:)
