Question

我的应用程序有一个顶部有导航控制器的视图控制器。导航栏标题为“忘记密码”。这个标题在iOS 5和6中没有任何换行符显示。但是当我在iOS 7中运行相同的应用程序时，导航栏标题在末尾显示为点 - “Forgot Passw ...”纠正此缺陷的唯一方法是减少导航栏标题的大小。

有人能告诉我该怎么办？ iOS 7中是否有专门用于此目的的API。是否可以单独减少此视图控制器的导航栏标题的字体大小？欢迎大家提出意见。提前致谢。

Answer 1

UILabel *nav_titlelbl=[[UILabel alloc]initWithFrame:CGRectMake(0, 0, self.navigationItem.titleView.frame.size.width,40)];
nav_titlelbl.text=@"Tests";

nav_titlelbl.textAlignment=NSTextAlignmentCenter;

UIFont *lblfont=[UIFont fontWithName:@"FontinSansCR-Bold" size:20];
[nav_titlelbl setFont:lblfont];
self.navigationItem.titleView=nav_titlelbl;

我在项目中使用了以下代码，并为我工作：

/* ios 7 Change */
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7)
    {
        //self.edgesForExtendedLayout = UIRectEdgeNone;
        //self.automaticallyAdjustsScrollViewInsets = NO;
        [[UINavigationBar appearance] setBarTintColor:UIColorFromRGB(0x4B678B)];
        NSShadow *shadow = [[NSShadow alloc] init];
        shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];
        shadow.shadowOffset = CGSizeMake(0, 1);
        [[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
                                                               [UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], NSForegroundColorAttributeName,
                                                               shadow, NSShadowAttributeName,
                                                               [UIFont fontWithName:@"Helvetica Neue" size:21.0], NSFontAttributeName, nil]];
        // self.navigationController.navigationBar.barTintColor = [UIColor blueColor];
        //[self.navigationController.navigationBar setBarStyle:UIBarStyleBlackTranslucent];
        [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];

    }

以下是我在自己的项目中使用的代码（iOS 7）

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {       

    // set the title text property, color, font, size and so on
    NSShadow *shadow = [[NSShadow alloc] init];
    shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];
    shadow.shadowOffset = CGSizeMake(0, 1);
    [[UINavigationBar appearance] setTitleTextAttributes:
           [NSDictionary dictionaryWithObjectsAndKeys:
           [UIColor WhiteColor],NSForegroundColorAttributeName,
           shadow, NSShadowAttributeName,
           [UIFont fontWithName:@"your font" size:21.0], NSFontAttributeName, nil]];

    return YES;
}

Answer 4

从iOS7开始，我总是这样做：

[[UINavigationBar appearance] setTitleTextAttributes:
    [NSDictionary dictionaryWithObjectsAndKeys:
        [UIFont fontWithName:@"Helvetica-Bold" size:SIZE_YOU_LIKE],NSFontAttributeName,
        nil]];

关键字UITextAttributeFont已经从iOS7中沮丧，你应该替换为 NSFontAttributeName。

只需设置SIZE_YOU_LIKE您喜欢的值〜
