NSString *url = @"www.apple.com" [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
打开另一个app还是可以通过openURL来实现。但是要分两种情况。第一种是启动内置的应用,一般的电话,浏览器,短信和
邮件可以直接调用并添加参数,譬如
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://10086"]]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://[email protected]"]]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://10086"]];
Step1. 右键,选择“Add Row”
Step2. Key值选择“URL types”
Step3. 打开“Item 0″,然后为该key增加一个URL identifier。可以是任何值,但建议用“反域名”(例如 “com.fcplayer.testHello”)。
Step4. 在“Item 0”下再加一行。
Step5. 选择“URL Schemes” 作为Key。
Step6. 输入你的URL协议名 (例如“testHello://” 应写做“testHello”)。如果有必要,你可以在这里加入多个协议。
其实在打开的时候只需要URL Schemes即可,URL identifier是可选项。如果需要传送参数,可以在URL Schemes://添加你的参数,格式和网页开发的传递参数差不多。(又或者URL Schemes://URL identifier@添加的参数)关键是要和接收参数方定义好处理的方式。然后在需要打开的地方添加代码:
NSString *url = @"URL Schemes的路径" [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
