UINavigationBar标题标签文本 [英] UINavigationBar title label text

问题描述

是否可以缩小标题文字以适应iOS中的 UINavigationBar 。

Is it possible to get the title text to shrink to fit in the UINavigationBar in iOS.

（对于没有自动布局的人像iPhone应用程序。。

(for portrait iPhone app with no autolayout).

我正在动态设置标题栏但有时文本太长而且此刻它只是将其切断省略号。

I'm setting the title bar dynamically but sometimes the text is too long and at the moment it just cuts it off with an ellipsis.

ie 这就是......

i.e. "This is the t..."

我希望它缩小文字。

推荐答案

您可以创建自己的标题视图来制作它。

You can create your own title view to make it.

这样的事情：

- (void)viewDidLoad
{
    [super viewDidLoad];

  //Do any additional setup after loading the view, typically from a nib.
     UILabel *titleLabelView = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 40)]; //<<---- Actually will be auto-resized according to frame of navigation bar;
    [titleLabelView setBackgroundColor:[UIColor clearColor]];
    [titleLabelView setTextAlignment: NSTextAlignmentCenter];
    [titleLabelView setTextColor:[UIColor whiteColor]];
    [titleLabelView setFont:[UIFont systemFontOfSize: 27]]; //<<--- Greatest font size
    [titleLabelView setAdjustsFontSizeToFitWidth:YES]; //<<---- Allow shrink
     // [titleLabelView setAdjustsLetterSpacingToFitWidth:YES];  //<<-- Another option for iOS 6+
    titleLabelView.text = @"This is a Title";

    navigationBar.topItem.titleView = titleLabelView;

    //....
}

希望这个帮助。
