1.打電話

   // iOS10以后調用會有延遲 處理如下
    
    CTTelephonyNetworkInfo *networkInfo = [[CTTelephonyNetworkInfo alloc] init];
    CTCarrier *carrier = [networkInfo subscriberCellularProvider];

    if (carrier.isoCountryCode) {
        NSString *urlStr = [NSString stringWithFormat:@"tel:%@",self.staffModel.phone];
        if ([UIDevice currentDevice].systemVersion.floatValue > 10.0) {
            dispatch_async(dispatch_get_global_queue(0, 0), ^{
                [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlStr] options:@{} completionHandler:^(BOOL success) {
                    sender.enabled = YES;
                }];
            });
        }else {
            dispatch_async(dispatch_get_global_queue(0, 0), ^{
                [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlStr]];
                sender.enabled = YES;
            });
        }
    } else {
        [MBProgressHUD bwm_showTitle:@"該手機未安裝SIM卡" toView:self.view hideAfter:MBHiddenTime];
        sender.enabled = YES;
    }

2.發(fā)短信

#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>

- (IBAction)clickSmsBtn:(id)sender {
    if( [MFMessageComposeViewController canSendText] ){
        MFMessageComposeViewController * controller = [[MFMessageComposeViewController alloc]init];;
        controller.recipients = [NSArray arrayWithObject:self.myText.text];
        controller.body = @"測試發(fā)短信";
        controller.messageComposeDelegate = self;
        [self presentViewController:controller animated:YES completion:nil];
    }else{
        NSLog(@"設備不具備短信功能");
    }
}
/*短信發(fā)送完成后返回app*/
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{
    [controller dismissViewControllerAnimated:YES completion:nil];
    if (result ==  MessageComposeResultSent) {
        NSLog(@"發(fā)送成功");
    }
}

3.發(fā)郵件

#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>

- (IBAction)clickEmailBtn:(id)sender {
    
    if ([MFMailComposeViewController canSendMail]) {
        
        MFMailComposeViewController* controller = [[MFMailComposeViewController alloc] init];
        controller.mailComposeDelegate = self;
        [controller setToRecipients:[NSArray arrayWithObjects:self.myText.text, nil]];
        [controller setSubject:@"郵件測試"];
        [controller setMessageBody:@"Hello " isHTML:NO];
        [self presentViewController:controller animated:YES completion:nil];
    }else{
        NSLog(@"設備不具備發(fā)送郵件功能");
    }
    
}
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
    if (result == MFMailComposeResultSent) {
        NSLog(@"郵件發(fā)送成功");
    }
    [self dismissViewControllerAnimated:YES completion:nil];
}

4.跳轉到應用商店

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms-apps://itunes.apple.com/cn/app/zsdl/id796332505?mt=8"]];
