准备

首先要引进例如以下三个framework：

MessageUI.framework

Social.framework

Accounts.framework

并在实现这几个方法的地方引入下面几个头文件

#import <MessageUI/MFMailComposeViewController.h>

#import <Social/Social.h>

#import <Accounts/Accounts.h>

Twitter及Facebook

当中urlStr为我分享的url字符串，你能够传你想分享的内容

//Twitter 、Facebook

- (void)shareUrl:(NSString *)urlStr ViaSLFrameWork:(NSString *)slType

{

    //only support fecebook and twitter

    if ([slType isEqualToString:SLServiceTypeFacebook] || [slType isEqualToString:SLServiceTypeTwitter])

    {

        if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])

        {

            SLComposeViewController *socialComposer = [SLComposeViewController composeViewControllerForServiceType:slType];

            [socialComposer addURL:[NSURL URLWithString:urlStr]];

            [socialComposer setCompletionHandler:^(SLComposeViewControllerResult result)

            {

                NSString *outStr = [NSString new];

                switch (result) {

                    case SLComposeViewControllerResultCancelled:

                        outStr = @"分享失败。";

                        break;

                    case SLComposeViewControllerResultDone:

                        outStr = @"分享失败！

";

                        break;

                    default:

                        break;

                }

                UIAlertView *myalertView = [[UIAlertView alloc]initWithTitle:nil

                                                                     message:outStr

                                                                    delegate:nil

                                                           cancelButtonTitle:@"Ok"

                                                           otherButtonTitles:nil];

                [myalertView show];

            }];

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

        }

    }

}

复制内容到剪切板

//URL复制

- (void)pasteUrl:(NSString *)url

{

    //复制文字

    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

    [pasteboard setString:url];

    //复制图片

    /*

    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

    [pasteboard setData:UIImageJPEGRepresentation([UIImage imageNamed:@"account_icon_friend.png"] , 1.0) forPasteboardType:@"public.jpeg"];*/

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"内容已拷贝到剪切板" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];

    [alert show];

}

LINE

当中urlStr为我要分享的内容。分享的为Text

//LINE

- (void)shareWithLine:(NSString *)urlStr

{

    //分享文字

    NSString *contentType = @"text";

    NSString *urlString = [NSString

                           stringWithFormat:@"line://msg/%@/%@",

                           contentType, [urlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    /******分享图片

    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

    [pasteboard setData:UIImageJPEGRepresentation([UIImage imageNamed:@"account_icon_friend.png"] , 1.0) forPasteboardType:@"public.jpeg"];

    NSString *contentType = @"image";

    NSString *urlString = [NSString

                           stringWithFormat:@"line://msg/%@/%@",

                           contentType, pasteboard.name]; //从剪切板中获取图片，文字亦能够如此

     */

    NSURL *url = [NSURL URLWithString:urlString];

    LorwyLog(@"%@",url);

    if ([[UIApplication sharedApplication] canOpenURL:url]) {

        [[UIApplication sharedApplication] openURL:url];

    }

    else{

        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@"无效的url" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];

        [alert show];

    }

}

MAIL

urlStr邮件内容，kMailAddress为目的邮件地址

PS:self须要实现MFMailComposeViewControllerDelegate协议才会发送邮件后调用以下第二个方法

//MAIL

- (void)shareUrlMail:(NSString *)urlStr

{

    if ([MFMailComposeViewController canSendMail])

    {

        MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];

        [mailViewController setSubject:kMailAddress];

        [mailViewController setMessageBody:urlStr isHTML:NO];

        mailViewController.mailComposeDelegate = self;

        mailViewController.navigationBar.tintColor = [UIColor blackColor];

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

    }

}

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

{

    [self dismissViewControllerAnimated:YES completion:nil];

}
