系统功能调用

一、调用系统的电话

//调用系统打电话功能
- (void)callPhoneNumber
{
    NSString *allString = [NSString stringWithFormat:@"tel:10086"];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:allString]];
}

二、调用系统的邮件功能

//调用系统邮箱
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://admin@hzlzh.com"]];

三、调用系统的Safari

   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.baidu.com"]];

四、调用系统的短信动能

1、该功能要进行一些相关配置操作

1）添加MessageUI.framework

2）导入头文件

#import <MessageUI/MFMessageComposeViewController.h>

3）遵守协议

<MFMessageComposeViewControllerDelegate>

//调用发短信方法
[self sendSMS:@"101" recipientList:@[@"10010"]];
//内容，收件人列表
- (void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSArray *)recipients
{
    
    MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
    
    if([MFMessageComposeViewController canSendText])
        
    {
        controller.body = bodyOfMessage;
        
        controller.recipients = recipients;
        
        controller.messageComposeDelegate = self;
        
        [self presentViewController:controller animated:YES completion:nil];
    }
    
}

// 处理发送完的响应结果
- (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");
                }

tip：调用系统的这几个功能都需要在真机上测试！
