iOS开发之--调用打电话，发邮件，发短信的系统功能的代码

1、调用 自带mail

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://admin@hzlzh.com"]];

2、调用 电话phone

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://8008808888"]];

NSMutableString *str=[[NSMutableString alloc] initWithFormat:@"tel:%@",self.experienceDetailModel.phone];
UIWebView *callWebview = [[UIWebView alloc] init];
[callWebview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:str]]];
[self.view addSubview:callWebview];

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"]];

发送短信

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")
    }
    else if(result == MessageComposeResultSent)
    {
        NSLog(@"Message sent")
    }
    else
    {
        NSLog(@"Message failed")
    }
                
}

发送邮件

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");
    }
    else if(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就ok了！
