几个系统Activity 类型的API

1.系统自带分享(UIActivityViewController)

//分享的标题
NSString *textToShare = @"分享的标题。";
//分享的图片
UIImage *imageToShare = [UIImage imageNamed:@"312.jpg"];
//分享的url
NSURL *urlToShare = [NSURL URLWithString:@"http://www.baidu.com"];
//在这里呢 如果想分享图片 就把图片添加进去 文字什么的同上
NSArray *activityItems = @[textToShare,imageToShare, urlToShare];
UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];
//不出现在活动项目
activityVC.excludedActivityTypes = @[UIActivityTypePrint, UIActivityTypeCopyToPasteboard,UIActivityTypeAssignToContact,UIActivityTypeSaveToCameraRoll];
[self presentViewController:activityVC animated:YES completion:nil];
// 分享之后的回调
activityVC.completionWithItemsHandler = ^(UIActivityType _Nullable activityType, BOOL completed, NSArray * _Nullable returnedItems, NSError * _Nullable activityError) {
if (completed) {
NSLog(@"completed");
//分享 成功
} else {
NSLog(@"cancled");
//分享 取消
}
};

2.复制链接功能

UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
pasteboard.string = @"需要复制的内容";
pasteboard.image = image;
pasteboard.url = url;

3.用safari打开网址

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://github.com/wslcmk"]];

4.保存图片到相册

UIImage *image = [UIImage imageNamed:@"wang"];
// 存储图片到"相机胶卷"
UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
// 成功保存图片到相册中, 必须调用此方法, 否则会报参数越界错误

• (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{
  }

5.发送短信

MFMessageComposeViewController *messageComposeViewController = [[MFMessageComposeViewController alloc] init];
messageComposeViewController.recipients = @[@"18682499853"];//收信人
messageComposeViewController.messageComposeDelegate = self;
messageComposeViewController.body = @"你好，我是且行且珍惜_iOS，请多指教！";
messageComposeViewController.subject = @"且行且珍惜_iOS";

6.发送邮件

MFMailComposeViewController *mailComposeViewController = [[MFMailComposeViewController alloc] init];
[mailComposeViewController setToRecipients:@[@"mattt@nshipster•com"]];
[mailComposeViewController setSubject:@"WSL"];
[mailComposeViewController setMessageBody:@"Lorem ipsum dolor sit amet"
isHTML:NO];
if([MFMailComposeViewController canSendMail]){
[self presentViewController:mailComposeViewController animated:YES completion:nil];
};

7.添加书签

NSURL *URL = [NSURL URLWithString:@"https://github.com/wslcmk"];
BOOL result = [[SSReadingList defaultReadingList] addReadingListItemWithURL:URL
title:@"WSL"
previewText:@"且行且珍惜_iOS"
error:nil];
if (result) {
NSLog(@"添加书签成功");
}
