在iOS開(kāi)發(fā)過(guò)程中，有時(shí)我們想在應(yīng)用內(nèi)實(shí)現(xiàn)打電話、發(fā)短信、打開(kāi)Safari瀏覽器功能，具體常用功能如下：

調(diào)用打電話功能（此種方法會(huì)直接進(jìn)行撥打電話,電話結(jié)束后會(huì)留在電話界面）

if ([[UIApplication sharedApplication] openURL:[NSURL    URLWithString:@"tel://185XXXX0496"]])
{
[[UIApplication sharedApplication] openURL:[NSURL   URLWithString:@"tel://185XXXX0496"]];
}

調(diào)用打電話功能（此種方法會(huì)詢問(wèn)是否撥打電話,電話結(jié)束后會(huì)返回到應(yīng)用界面,但是有上架App Store被拒的案例）

if ([[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"telprompt://185XXXX0496"]])
{
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"telprompt://185XXXX0496"]];
}

調(diào)用打電話功能（此種方法會(huì)詢問(wèn)是否撥打電話,電話結(jié)束后會(huì)返回到應(yīng)用界面,此種方法是加載了一個(gè)UIWebView實(shí)現(xiàn),支持上架App Store）

    UIWebView *webView = [[UIWebView alloc] init];
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"tel://185XXXX0496"]]];
[self.view addSubview:webView];

調(diào)用發(fā)短信功能（此種方法會(huì)直接跳轉(zhuǎn)到給指定號(hào)碼發(fā)送短信,短信結(jié)束后會(huì)留在短信界面）

if ([[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://185XXXX0496"]])
{
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://185XXXX0496"]];
}

調(diào)用Safari瀏覽器功能(在開(kāi)發(fā)中遇到應(yīng)用內(nèi)打開(kāi)網(wǎng)頁(yè)的需求,建議使用UIWebView打開(kāi))

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"http://www.baidu.com/"]])
{
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.baidu.com/"]];
}

iOS跳轉(zhuǎn)到系統(tǒng)設(shè)置

在iOS開(kāi)發(fā)過(guò)程中，有時(shí)我們想在應(yīng)用內(nèi)實(shí)現(xiàn)跳轉(zhuǎn)到系統(tǒng)設(shè)置界面，具體常用功能如下：

注意：想要實(shí)現(xiàn)應(yīng)用內(nèi)跳轉(zhuǎn)到系統(tǒng)設(shè)置界面功能,需要先在Targets-Info-URL Types-URL Schemes中添加prefs

跳轉(zhuǎn)到WIFI設(shè)置

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"prefs:root=WIFI"]])
{
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=WIFI"]];
}

跳轉(zhuǎn)到藍(lán)牙

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"prefs:root=Bluetooth"]])
{
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=Bluetooth"]];
}

跳轉(zhuǎn)到通用

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"prefs:root=General"]])
{
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General"]];
}

跳轉(zhuǎn)到關(guān)于本機(jī)

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"prefs:root=General&path=About"]])
{
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General&path=About"]];
}

跳轉(zhuǎn)到定位服務(wù)

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]])
{
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]];
}

跳轉(zhuǎn)到通知

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"prefs:root=NOTIFICATIONS_ID"]])
{
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=NOTIFICATIONS_ID"]];
}
