检查String是否与另一个字符串部分匹配

标签: ios nsstring nsarray mkmapview uisearchbar

我的地图视图上有一个搜索栏,允许用户搜索名称(注释标题)或地址(注释字幕)。如果用户输入整个标题或副标题,我就可以正常工作,但我正在尝试使用它,因此用户只需输入部分名称或地址。例如,Cates Farm有一个注释。我希望用户能够只输入cates并让它找到注释。我设置的方式不仅仅是找到数组中的最后一个标题,而且运行缓慢。有任何帮助或建议吗?

这是我的代码。如果用户输入整个标题或副标题,我已经注释掉的行就是我工作的地方。

我现在正在尝试实现indexOfObjectPassingTest方法来完成我想要的但我似乎无法弄清楚如何根据我的需要实现它。

以下是更好上下文的所有代码:

你在annTitle中找到了searchText的范围(即位置),它是由ann objet构建的,它是从....什么都没有建立的(你的函数的第1行)。

rangeOfString行移至循环中,以便检查ann

中每个marketLocations内的searchText
