iOS实现APP调用打电话,发短信,发邮件,打开Safari

打电话:

- (IBAction)phone:(id)sender {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://123456789"]];
}

打开Safari:

- (IBAction)Safari:(id)sender {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://www.google.com.hk"]];
}

发短信:
发短信需要导入#import <MessageUI/MFMessageComposeViewController.h>头文件,并遵守MFMessageComposeViewControllerDelegate代理,实现如下步骤,

- (IBAction)msg:(id)sender {
// [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://123456789"]];
    MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];

if([MFMessageComposeViewController canSendText])

    {

        controller.body = @"hhhhHhhhhhhhhhhhhhhh";//信息内容

        controller.recipients = @[@"123456789"];//接收者,是一个数组,可以发送给多人

        controller.messageComposeDelegate = self;


        [self presentViewController:controller animated:YES completion:nil];
    }

}

发送短信完成的代理方法:

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {
    [self dismissViewControllerAnimated:YES completion:nil];

if (result == MessageComposeResultCancelled)
NSLog(@"Message cancelled");
else if (result == MessageComposeResultSent)
NSLog(@"Message sent");
else
NSLog(@"Message failed");

}

发邮件:
发邮件需要导入#import <MessageUI/MFMailComposeViewController.h>头文件,并遵守MFMailComposeViewControllerDelegate代理,实现如下步骤,

- (IBAction)mail:(id)sender {
    MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init];

if([MFMailComposeViewController canSendMail])

    {

        [controller setSubject:@"send email!!!"];//邮件主题

        [controller setToRecipients:@[@"[e-mail]"]];//收件人

        [controller setCcRecipients:@[@"[e-mail]"]];//抄送

        [controller setMessageBody:@"hello world!" isHTML:NO];

        controller.mailComposeDelegate = self;

        [self presentViewController:controller animated:YES completion:nil];

    }
}

发送邮件完成的代理方法:

- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {

    [self dismissViewControllerAnimated:YES completion:nil];

if (result == MessageComposeResultCancelled)
NSLog(@"Message cancelled");
else if (result == MessageComposeResultSent)
NSLog(@"Message sent");
else
NSLog(@"Message failed");

}
