IOS 开发，调用系统功能打电话，发短信，群发短信，打开网址，发邮件等自带功能

Sian

1、调用 自带mail
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://[email protected]"]];

2、调用 电话phone
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://8008808888"]];

3、调用 SMS
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://800888"]];

4、调用自带 浏览器 safari
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.hzlzh.com"]];

调用phone可以传递号码，调用SMS 只能设定号码，不能初始化SMS内容。

若需要传递内容或群发可以做如下操作：
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

1. - (void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSArray *)recipients
2. {
3.    
4.     MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
5.    
6.     if([MFMessageComposeViewController canSendText]){
7.         
8.         controller.body = bodyOfMessage;
9.         
10.         controller.recipients = recipients;
11.         
12.         controller.messageComposeDelegate = self;
13.         
14.         [self presentViewController:controller animated:YES completion:nil];
15.         
16.     }   
17.    
18. }

复制代码

// 处理发送完的响应结果

1. - (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
2. {
3.   [self dismissModalViewControllerAnimated:YES];
5.   if (result == MessageComposeResultCancelled)
6.     NSLog(@"Message cancelled")
7.   else if (result == MessageComposeResultSent)
8.     NSLog(@"Message sent")  
9.   else
10.     NSLog(@"Message failed")  
11. }

复制代码

发送邮件的为：
导入#import <MessageUI/MFMailComposeViewController.h>
实现代理：MFMailComposeViewControllerDelegate

//发送邮件

1. -(void)sendMail:(NSString *)subject content:(NSString *)content{
3.     MFMailComposeViewController *controller = [[[MFMailComposeViewController alloc] init] autorelease];
5.     if([MFMailComposeViewController canSendMail])
7.     {
9.         [controller setSubject:subject];
11.         [controller setMessageBody:content isHTML:NO];
13.         controller.mailComposeDelegate = self;
15.         [self presentModalViewController:controller animated:YES  completion:nil];
17.     }   
18. }

复制代码

//邮件完成处理

1. -(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{
3.     [self dismissModalViewControllerAnimated:YES completion:nil];
5.     if (result == MessageComposeResultCancelled)
6.         NSLog(@"Message cancelled");
7.     else if (result == MessageComposeResultSent)
8.         NSLog(@"Message sent");
9.     else
10.         NSLog(@"Message failed");  
12. }

默认发送短信的界面为英文的，解决办法为：
在.xib 中的Localization添加一组chinese就ok了
