在相应的代码中写入：
1、调用 电话phone
[[UIApplication sharedApplication]
openURL:[NSURL URLWithString:@"tel://4008008288"]];
2、调用自带 浏览器 safari
[[UIApplication sharedApplication] openURL:[NSURL
URLWithString:@"http://www.abt.com"]];
3、调用 自带mail
[[UIApplication sharedApplication] openURL:[NSURL
URLWithString:@"mailto://[email protected]"]];
4、调用 SMS
[[UIApplication sharedApplication] openURL:[NSURL
URLWithString:@"sms://800888"]];
5，跳转到系统设置相关界面
[[UIApplication
sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=WIFI"]];
其中，发短信，发Email的功能只能填写要发送的地址或号码，无法初始化发送内容，如果想实现内容的话，还需要更复杂一些，实现其各自的委托方法。
若需要传递内容可以做如下操作：
加入：MessageUI.framework
#import <MessageUI/MFMessageComposeViewController.h>
实现代理：MFMessageComposeViewControllerDelegate
调用sendSMS函数
//内容，收件人列表
- (void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSArray *)recipients
{
MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
if([MFMessageComposeViewController canSendText])
{
controller.body = bodyOfMessage;
controller.recipients = recipients;
controller.messageComposeDelegate = self;
[self presentModalViewController:controller animated:YES];
}
}
// 处理发送完的响应结果
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
[self dismissModalViewControllerAnimated:YES];
if (result == MessageComposeResultCancelled)
NSLog(@"Message cancelled")
elseif (result == MessageComposeResultSent)
NSLog(@"Message sent")
else
NSLog(@"Message failed")
}
发送邮件的为：
导入#import <MessageUI/MFMailComposeViewController.h>
实现代理：MFMailComposeViewControllerDelegate
//发送邮件
-(void)sendMail:(NSString *)subject content:(NSString *)content{
MFMailComposeViewController *controller = [[[MFMailComposeViewController alloc] init] autorelease]; if([MFMailComposeViewController canSendMail])
{
[controller setSubject:subject];
[controller setMessageBody:content isHTML:NO];
controller.mailComposeDelegate = self;
[self presentModalViewController:controller animated:YES];
}
}
//邮件完成处理
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{
[self dismissModalViewControllerAnimated:YES];
if (result == MessageComposeResultCancelled)
NSLog(@"Message cancelled");
elseif (result == MessageComposeResultSent)
NSLog(@"Message sent");
else NSLog(@"Message failed");
}
默认发送短信的界面为英文的，解决办法为：在.xib 中的Localization添加一組chinese
