iOS调用系统分享功能

调用下面的方法即可实现系统分享功能

//分享

- (IBAction)RespostClick_Action:(id)sender {

UIImage* image = [UIImage imageNamed:@"icon_share.png"];

NSString *text = @"I found an Awesome application software! InstaDown";

//https://itunes.apple.com/us/app/id1260302654?l=zh&ls=1&mt=8

NSURL *urlToShare = [NSURL URLWithString:[NSString stringWithFormat:@"https://itunes.apple.com/us/app/id%@?l=zh&ls=1&mt=8",[HHLADSManager getValueFromjsondata:@"appid"]]];

NSArray *activityItems = @[text,image,urlToShare];

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

[self presentViewController:avc animated:TRUE completion:nil];

// 选中分享类型

[avc setCompletionWithItemsHandler:^(NSString * __nullable activityType, BOOL completed, NSArray * __nullable returnedItems, NSError * __nullable activityError){

// 显示选中的分享类型

NSLog(@"act type %@",activityType);

if (completed) {

NSLog(@"ok");

}else {

NSLog(@"no ok");

}

}];

UIPopoverPresentationController *popover = avc.popoverPresentationController;

if (popover) {

popover.sourceView = self.view;

popover.sourceRect = self.view.bounds;

popover.permittedArrowDirections = UIPopoverArrowDirectionUp;

}

}
