MyAnnotation在iphone谷歌地图中查看多行文字 [英] MyAnnotation view multiple lines text in iphone google map

问题描述

MKCoordinateRegion region1; 
    region1.center.latitude = 50.366772;
    region1.center.longitude = 20.010607;
    region1.span.longitudeDelta = 0.01f;
    region1.span.latitudeDelta = 0.01f;     


    MyAnnotation *ann1 = [[MyAnnotation alloc] init];
    ann1.title = @"Text1";
    ann1.subtitle = @"Text2\n, Text3\n, Text4\n";   
    ann1.coordinate = region1.center;
    [mapView addAnnotation:ann1];

我想在谷歌地图中显示字幕的多行文字。如果我给\ n打破该行，它会直接显示谷歌地图中的\ n。如何显示多行？

I want to show the multiple line text for subtitle in google map.If i give the \n to break the line,it display directly the \n in google map.How can i show the multilple lines?

谢谢。

推荐答案

默认样式仅支持标题和副标题。标题和副标题都不能包含换行符。如果没有子类化，则无法执行此操作。

The default style only supports the title and subtitle. Neither title nor subtitle can include line breaks. You cannot do this without subclassing.

要使用自定义视图，请查看Apple的示例代码：

To use a custom view review Apple's sample code:
