如何在Objective C的导航栏上添加字体真棒

Question

我是 iOS 新手。我在 UINavigation Bar 上添加很棒的字体时遇到了问题。我正在使用像这样的图像代码

  UIImage *listImage2 = [UIImage imageNamed:@"Image1.png"];
    UIButton *listButton2 = [UIButton buttonWithType:UIButtonTypeCustom];
    CGRect listButton2Frame = listButton2.frame;
    listButton2Frame.size = listImage2.size;
    listButton2.frame = listButton2Frame;

    [listButton2 setImage:listImage2 forState:UIControlStateNormal];
    [listButton2 addTarget:self
                    action:@selector(LogoutClick:)
          forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *jobsButton2 =
    [[UIBarButtonItem alloc] initWithCustomView:listButton2];


    UIImage *listImage4 = [UIImage imageNamed:@"Image2.png"];
    UIButton *listButton4 = [UIButton buttonWithType:UIButtonTypeCustom];

    // get the image size and apply it to the button frame
    CGRect listButton4Frame = listButton4.frame;
    listButton4Frame.size = listImage4.size;
    listButton4.frame = listButton4Frame;

    [listButton4 setImage:listImage4 forState:UIControlStateNormal];
    [listButton4 addTarget:self
                    action:@selector(ActualNotificationClick:)
          forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *jobsButton4 =
    [[UIBarButtonItem alloc] initWithCustomView:listButton4];

    UIImage *listImage3 = [UIImage imageNamed:@"Image3.png"];
    UIButton *listButton3 = [UIButton buttonWithType:UIButtonTypeCustom];

    // get the image size and apply it to the button frame
    CGRect listButton3Frame = listButton3.frame;
    listButton3Frame.size = listImage3.size;
    listButton3.frame = listButton3Frame;

    [listButton3 setImage:listImage3 forState:UIControlStateNormal];
    [listButton3 addTarget:self
                    action:@selector(EmployeeClick:)
          forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *jobsButton3 =
    [[UIBarButtonItem alloc] initWithCustomView:listButton3];

    self.navigationItem.rightBarButtonItems= [NSArray arrayWithObjects:jobsButton2,jobsButton4, nil];
    self.navigationItem.leftBarButtonItems=[NSArray arrayWithObjects:jobsButton3, nil];

对于字体真棒我正在使用这样的代码

lab.font = [UIFont fontWithName:@"FontAwesome" size:25];
lab.textColor =  [UIColor whiteColor];
lab.text =  [NSString awesomeIcon:FaCalendarChecko]; 

我需要在 UINavigation Bar 上添加字体 awesome Label 而不是图像。 我使用的图像看起来像这样

我有像这段代码一样添加字体真棒

newjoinlbl.font = [UIFont fontWithName:@"FontAwesome" size:8];
    newjoinlbl.textColor =  [UIColor whiteColor];
    newjoinlbl.text =  [NSString awesomeIcon:FaChild];
    UIButton *listButton2 = [UIButton buttonWithType:UIButtonTypeCustom];

    // get the image size and apply it to the button frame
    CGRect listButton2Frame = listButton2.frame;
    listButton2Frame.size = listImage2.size;
    listButton2.frame = listButton2Frame;

    [listButton2 setTitle:newjoinlbl.text forState:UIControlStateNormal];
    [listButton2 addTarget:self
                    action:@selector(LogoutClick:)
          forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *jobsButton2 =
    [[UIBarButtonItem alloc] initWithCustomView:listButton2];

但它给了我这样的输出

字体真棒在视图中正常工作

我只需要在 UIAvigation Bar 上添加字体真棒标签而不是图像。提前致谢！

试试看，

   UIImage *listImage4 = [UIImage imageNamed:@"Image2.png"];

UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 30, 30)]; // desired frame

[label setFont: [UIFont fontWithName:@"FontAwesome" size:25]]; //desired fornt


UIButton *listButton4 = [UIButton buttonWithType:UIButtonTypeCustom];

// get the image size and apply it to the button frame
CGRect listButton4Frame = listButton4.frame;
listButton4Frame.size = listImage4.size;
listButton4.frame = listButton4Frame;

[listButton4 setTitle:label.text forState:UIControlStateNormal];
//  [listButton4 setImage:listImage4 forState:UIControlStateNormal];
[listButton4 addTarget:self
                action:@selector(ActualNotificationClick:)
      forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *jobsButton4 =
[[UIBarButtonItem alloc] initWithCustomView:listButton4];

更新：

尝试设置attributed string点赞，

 UIImage *listImage4 = [UIImage imageNamed:@"Image2.png"];


UIButton *listButton4 = [UIButton buttonWithType:UIButtonTypeCustom];

// get the image size and apply it to the button frame
CGRect listButton4Frame = listButton4.frame;
listButton4Frame.size = listImage4.size;
listButton4.frame = listButton4Frame;

UIFont *font = [UIFont fontWithName:@"FontAwesome" size:25.0];
NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObject:font
                                                            forKey:NSFontAttributeName];
NSAttributedString *attributedStr = [[NSAttributedString alloc] initWithString:@"yourTitleString" attributes:attrsDictionary];





[listButton4 setAttributedTitle:attributedStr forState:UIControlStateNormal];


[listButton4 addTarget:self
                action:@selector(ActualNotificationClick:)
      forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *jobsButton4 =
[[UIBarButtonItem alloc] initWithCustomView:listButton4];

更新 2

  UIFont *font = [UIFont fontWithName:@"FontAwesome" size:25.0];
UIColor *color = [UIColor whiteColor];

NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObject:font
                                                            forKey:NSFontAttributeName];
[NSDictionary dictionaryWithObjectsAndKeys:font,NSFontAttributeName,color,NSForegroundColorAttributeName, nil];

NSAttributedString *attributedStr = [[NSAttributedString alloc] initWithString:@"yourTitleString" attributes:attrsDictionary];
