准备
首先要引进如下三个framework：
MessageUI.framework
Social.framework
Accounts.framework
并在实现这几个方法的地方引入以下几个头文件
#import <MessageUI/MFMailComposeViewController.h>
#import <Social/Social.h>
#import <Accounts/Accounts.h>
Twitter及Facebook
其中urlStr为我分享的url字符串，你可以传你想分享的内容
//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:@"内容已复制到剪切板" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[alert show];
}
LINE
其中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，文字亦可以如此
*/
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];
}
}
urlStr邮件内容，kMailAddress为目的邮件地址
PS:self需要实现MFMailComposeViewControllerDelegate协议才会发送邮件后调用下面第二个方法
//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];
}
