UIActivityViewController系统原生分享UI

初始化
1，activityItems要分享的数据内容

2，applicationActivities要分享的类型
//自定义 customActivity继承于UIActivity,创建自定义的Activity加在数组Activities中。

• (instancetype)initWithActivityItems:(NSArray *)activityItems applicationActivities:(nullable NSArray<__kindof UIActivity *> *)applicationActivities
  NSString *textToShare = @"欢迎关注我！";
  UIImage *imageToShare = [UIImage imageNamed:@"1.png"];
  NSURL *urlToShare = [NSURL URLWithString:@"https://github.com"];
  NSArray *activityItems = @[urlToShare,textToShare,imageToShare];

UIActivity * applicationActivities = [[UIActivity alloc] init];
[custom prepareWithActivityItems:activityItems];
NSArray *activities = @[applicationActivities];

UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:activities];

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