openURL的使用方法

openURL的使用方法：

view plaincopy to clipboardprint?

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:appString]];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:appString]];

其中系统的appString有：

view plaincopy to clipboardprint?

Map http://maps.google.com/maps?q=Shanghai
Email mailto://myname@google.com

Tel tel://10086

Msg sms://10086

Map http://maps.google.com/maps?q=Shanghai
Email mailto://myname@google.com

Tel tel://10086

Msg sms://10086

除此之外，还可以自己定义URL，方法如下：

打开info.plist，添加一项URL types

展开URL types，再展开Item1，将Item1下的URL identifier修改为URL Scheme

展开URL Scheme，将Item1的内容修改为myapp

其他程序可通过myapp://访问此自定义URL

openURL能帮助你运行Maps，SMS，Browser,Phone甚至其他的应用程序。这是Iphone开发中我经常需要用到的一段代码，它仅仅只有一行而已。
