The implementation of phone texting and other functions in iOS development

<span id="Label3"></p><p><p>In app development, it may involve the functions of making calls, texting, and sending Emails. For example, usually a product "about" page, there will be a Developer's contact, ideally, when the user clicks on the phone number, can automatically help users dial out, it involves the function of the PHONE.</p></p><p><p>In iOS development, there are three ways to Call:</p></p><p><p>(1) jump directly to the dial-up interface, the code is as follows</p></p> <table border="0" cellspacing="0" cellpadding="0"> <tbody> <tr> <td class="gutter">12</td> <td class="code"><code class="objc keyword">NSURL</code><code class="objc plain">*url = [</code><code class="objc keyword">NSURL</code><code class="objc plain">URLWithString:@</code><code class="objc string">"tel://10010"</code><code class="objc plain">];</code><code class="objc spaces"> </code><code class="objc plain">[[UIApplication sharedApplication] openURL:url];</code></td> </tr> </tbody> </table><p><p>Disadvantage: after the call is finished, will not automatically return to the original application, directly stay on the call log Page.</p></p><p><p>(2) before dialing the box to ask, after the call can automatically return to the original Application. The code is as Follows:</p></p> <table border="0" cellspacing="0" cellpadding="0"> <tbody> <tr> <td class="gutter">12</td> <td class="code"><code class="objc keyword">NSURL</code><code class="objc plain">*url = [</code><code class="objc keyword">NSURL</code><code class="objc plain">URLWithString:@</code><code class="objc string">"telprompt://10010"</code><code class="objc plain">];</code><code class="objc plain">[[UIApplication sharedApplication] openURL:url];</code></td> </tr> </tbody> </table><p><p>Cons: private api, So may not pass Apple official Audit. If you are an enterprise application (no online AppStore required), You can use this Method.</p></p><p><p>(3) Create a UIWebView to load the url, after the dial can automatically return to the original Application. The code is as Follows:</p></p> <table border="0" cellspacing="0" cellpadding="0"> <tbody> <tr> <td class="gutter">123</td> <td class="code"><code class="objc plain">UIWebView *webView = [[UIWebView alloc]init];</code><code class="objc keyword">NSURL</code><code class="objc plain">*url = [</code><code class="objc keyword">NSURL</code> <code class="objc plain">URLWithString:@</code><code class="objc string">"tel://10010"</code><code class="objc plain">];</code><code class="objc plain">[webView loadRequest:[</code><code class="objc keyword">NSURLRequest</code><code class="objc plain">requestWithURL:url ]];</code></td> </tr> </tbody> </table><p><p>It is recommended to use the third Method.</p></p><p><p>There are two ways to send text Messages.</p></p><p><p>(1) jump directly to the texting INTERFACE.
