iOS开发笔记--iOS 跳转到系统的设置界面【适用iOS7.1、8.3、9.1】

在项目中，我们经常会碰到使用位置的需求。当用户设置app不允许使用位置的时候，最好的用户体验就是直接调转到系统的位置设置界面，进行设置。

本人已经测试，在5c/6 iOS8.3系统、6 iOS9.1系统和 5s iOS7.1系统中可以正常跳转

1.跳转到自己的项目中

在需要调转的按钮动作中添加如下的代码，就会跳转到设置中自己的app的设置界面，这里会有通知和位置权限的设置

<code class="hljs ruby has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-constant" style="box-sizing: border-box;">NSURL</span> * url = [<span class="hljs-constant" style="box-sizing: border-box;">NSURLURLWithString</span><span class="hljs-symbol" style="color: rgb(0, 102, 102); box-sizing: border-box;">:UIApplicationOpenSettingsURLString</span>]；
<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">if</span>([[<span class="hljs-constant" style="box-sizing: border-box;">UIApplicationsharedApplication</span>] <span class="hljs-symbol" style="color: rgb(0, 102, 102); box-sizing: border-box;">canOpenURL:</span>url]) {
<span class="hljs-constant" style="box-sizing: border-box;">NSURL</span>*url =[<span class="hljs-constant" style="box-sizing: border-box;">NSURLURLWithString</span><span class="hljs-symbol" style="color: rgb(0, 102, 102); box-sizing: border-box;">:UIApplicationOpenSettingsURLString</span>]; [[<span class="hljs-constant" style="box-sizing: border-box;">UIApplicationsharedApplication</span>] <span class="hljs-symbol" style="color: rgb(0, 102, 102); box-sizing: border-box;">openURL:</span>url];
}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li></ul>

**测试注意
新项目测试，需要请求一下位置权限或者通知权限，才可以跳进自己的app设置里面，如果没有任何权限请求，就只能跳到系统的设置界面**

2.跳转到系统设置的其他界面

在点击跳转的按钮动作中添加如下代码

<code class="hljs lua has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=WIFI"]]</span>;</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

在项目中的info中添加 URL types
添加 URL Schemes 为 prefs的url
这里写图片描述
这样点击就可以跳转到wifi设置界面
（测试手机 5c 8.3系统 5s 7.1系统）

3.跳转到其他的界面的字段

<code class="hljs mathematica has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">About — prefs:root=<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">General</span>&path=About
