ios原生分享

什么是 ios 系统的原生分享呢，如下图所示

具体使用系统UIActivityViewController，完整代码如下：

-(void)shareAny:(NSString *)text url:(NSString *)_url imagePath:(NSString *)_imagePath
{NSLog(@"shareAny, text:%@, url:%@, imagePath:%@", text, _url, _imagePath);NSString *textToShare = text;//需要分享的文本内容NSArray *activityItems = @[textToShare];if (_url != nil) {NSURL *urlToShare = [NSURL URLWithString:_url];//需要分享的URLactivityItems = @[textToShare, urlToShare];}if (_imagePath != nil) {UIImage *imageToShare = [UIImage imageWithContentsOfFile:_imagePath];//需要分享的图片activityItems = @[textToShare, imageToShare];}UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];// 禁用分享渠道activityVC.excludedActivityTypes = @[UIActivityTypePrint, UIActivityTypeCopyToPasteboard,UIActivityTypeAssignToContact,UIActivityTypeSaveToCameraRoll];// 分享之后的回调activityVC.completionWithItemsHandler = ^(UIActivityType  _Nullable activityType, BOOL completed, NSArray * _Nullable returnedItems, NSError * _Nullable activityError) {if (completed) {NSLog(@"成功分享,分享平台%@",activityType);}else{NSLog(@"取消分享");};};[self.viewController presentViewController:activityVC animated:true completion:nil];
}

分享到WhatsApp

- (void) whatsappShareText:(NSString*)text {NSLog(@"whatsapp share text %@", text);NSString *url = [NSString stringWithFormat:@"whatsapp://send?text=%@", [text stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLHostAllowedCharacterSet]]];NSURL *whatsappURL = [NSURL URLWithString: url];if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {[[UIApplication sharedApplication] openURL: whatsappURL];} else {// Cannot open whatsappNSLog(@"whatsapp cant't open");}
}

分享到Facebook

- (void) facebookShareUrl:(NSString *)url {NSLog(@"facebook share url %@", url);if(![self checkAPPIsExist:@"fb"]) {NSLog(@"facebook is not exits");return;;}// 首先判断某个平台是否可用（如果未绑定账号则不可用）if (![SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {NSLog(@"facebook is not available");return;}// 创建控制器，并设置ServiceTypeSLComposeViewController *composeVC = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];// 添加要分享的url[composeVC addURL:[NSURL URLWithString:url]];// 弹出分享控制器[self.viewController presentViewController:composeVC animated:YES completion:nil];// 监听用户点击事件composeVC.completionHandler = ^(SLComposeViewControllerResult result){if (result == SLComposeViewControllerResultDone) {NSLog(@"facebook share send");}else if (result == SLComposeViewControllerResultCancelled){NSLog(@"facebook share cancel");}};
}- (void) facebookShareImage:(NSString *)imagePath {NSLog(@"facebook share image %@", imagePath);if(![self checkAPPIsExist:@"fb"]) {NSLog(@"facebook is not exits");return;}// 首先判断某个平台是否可用（如果未绑定账号则不可用）if (![SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {NSLog(@"facebook is not available");return;}// 创建控制器，并设置ServiceTypeSLComposeViewController *composeVC = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];// 添加要分享的图片[composeVC addImage:[UIImage imageWithContentsOfFile:imagePath]];// 弹出分享控制器[self.viewController presentViewController:composeVC animated:YES completion:nil];// 监听用户点击事件composeVC.completionHandler = ^(SLComposeViewControllerResult result){if (result == SLComposeViewControllerResultDone) {NSLog(@"facebook share send");}else if (result == SLComposeViewControllerResultCancelled){NSLog(@"facebook share cancel");}};
}//判断是否安装APP
-(BOOL)checkAPPIsExist:(NSString*)URLScheme{NSURL* url;if ([URLScheme containsString:@"://"]) {url = [NSURL URLWithString:[NSString stringWithFormat:@"%@",URLScheme]];} else {url = [NSURL URLWithString:[NSString stringWithFormat:@"%@://",URLScheme]];}if ([[UIApplication sharedApplication] canOpenURL:url]){return YES;} else {return NO;}
