1创建UIActivityViewController 有连个数组类型的参数一个填写分享内容的详细信息，另一个现在不需要关注。

UIActivityViewController *activityView = [[UIActivityViewController alloc] initWithActivityItems:@[@"这里是标题", [UIImage imageNamed:@"Oauth"], [NSURL URLWithString:@"http://www.google.com"]] applicationActivities:activity];

2，添加不需要展示的ActivityTypes

activityView.excludedActivityTypes = @[UIActivityTypeAssignToContact, UIActivityTypeCopyToPasteboard, UIActivityTypePrint];

3，展示

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

二

//分享的标题

NSString *textToShare = @"带你看世界。";

//分享的图片

UIImage *imageToShare = [UIImage imageNamed:@"图片名称"];

//分享的url

NSURL *urlToShare = [NSURL URLWithString:@"www.baidu.com"];

//在这里呢 如果想分享图片 就把图片添加进去  文字什么的通上

NSArray *activityItems = @[textToShare,imageToShare, urlToShare];

UIActivityViewController *activityView = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];

// activityView.excludedActivityTypes = @[UIActivityTypeAirDrop];

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