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

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

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

    //调用打开网址
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.baidu.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。

发短信邮件需要的框架

导入头文件#import <MessageUI/MessageUI.h>

协议：<MFMailComposeViewControllerDelegate,MFMessageComposeViewControllerDelegate>

//点击按钮后，触发这个方法
-(void)sendEMail

    //设置主题

    // 添加发送者
    NSArray *toRecipients = [NSArray arrayWithObject: @"[email protected]"];
    
    [mailPicker setToRecipients: toRecipients];
    
    // 添加图片
    UIImage *addPic = [UIImage imageNamed: @"ios.jpg"];
    NSData *imageData = UIImagePNGRepresentation(addPic);            // png
