IOS 开发，调用打电话，发短信，打开网址

来源：互联网发布：娱乐圈的水有多深知乎编辑：程序博客网时间：2024/04/28 04:49

1、调用自带mail

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

2、调用电话phone
// 方法1，将返回系统通话
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://8008808888"]];

// 方法2，将返回APP
第一种是用UIWebView加载电话，这种是合法的，可以上App Store的。

代码如下：

    // assuming you have an ivar to store a weak reference to a UIWebView:
    // UIWebView *phoneCallWebView;
    - (void) dialPhoneNumber:(NSString *)aPhoneNumber
    {
        NSURL *phoneURL = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@",aPhoneNumber]];
        if ( !phoneCallWebView ) {
            phoneCallWebView = [[UIWebView alloc] initWithFrame:CGRectZero];
        }
        [phoneCallWebView loadRequest:[NSURLRequest requestWithURL:phoneURL]];
    }
    - (void) dealloc
    {
        // cleanup
        [phoneCallWebView release], phoneCallWebView = nil;
       [super dealloc];
    }

第二种是私有方法，不能上App Store的。

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"telprompt://10086"]];

看到了吗，其实就是改tel为telprompt.

这样，当电话结束手就可以返回到自己的应用程序。是不是很爽呢？

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"]];

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")
}

发送邮件的为：

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");

}
