这几天写项目的时候,发现,有好多的控制器都有分享.每一次,分享的内容虽然不一样,但是格式大致一样,而且代码繁多,出不多几十行.所以考虑之后,就封装了一下.
写一个类,继承NSObject
+ (instancetype)share;
/**
分享
@param urlStr 分享的网页URL
@param imageUrl 图片URL
@param title 分享标题
@param descr 分享内容的描述
*/
- (void)shareURL:(NSString *)urlStr image:(NSString *)imageUrl shareTitle:(NSString *)title descr:(NSString *)descr;
在.m中实现方法
// 获取
+ (instancetype)share {
return [[self alloc] init];
}
// 实现分享的方法
- (void)shareURL:(NSString *)urlStr image:(NSString *)imageUrl shareTitle:(NSString *)title descr:(NSString *)descr {
self.urlStr = urlStr;
self.imageUrl = imageUrl;
self.title = title;
self.descr = descr;
// 这里面分享的平台是我们公司要求分享到的. 大家可以根据自己的要求改
[UMSocialUIManager setPreDefinePlatforms:@[@(UMSocialPlatformType_QQ),@(UMSocialPlatformType_WechatSession),@(UMSocialPlatformType_Sina),@(UMSocialPlatformType_WechatTimeLine),@(UMSocialPlatformType_Qzone)]];
[[UMSocialShareUIConfig shareInstance] shareCancelControlConfig].isShow = NO;
[[UMSocialShareUIConfig shareInstance] shareTitleViewConfig].isShow = NO;
//显示分享面板
[UMSocialUIManager showShareMenuViewInWindowWithPlatformSelectionBlock:^(UMSocialPlatformType platformType, NSDictionary *userInfo) {
[self shareWebPageToPlatformType:platformType];
}];
}
- (void)shareWebPageToPlatformType:(UMSocialPlatformType)platformType {
LJLog(@"%@",self.urlStr);
NSURL *url = [NSURL URLWithString:self.imageUrl];
UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:url]];
NSData *imageData = UIImageJPEGRepresentation(image, 0.3f);
UIImage* shareImg = [UIImage imageWithData:imageData];
//创建分享消息对象
UMSocialMessageObject *messageObject = [UMSocialMessageObject messageObject];
//创建网页内容对象
UMShareWebpageObject *shareObject = [UMShareWebpageObject shareObjectWithTitle:self.title descr:self.descr thumImage:shareImg];
//设置网页地址
shareObject.webpageUrl = self.urlStr;
//分享消息对象设置分享内容对象
messageObject.shareObject = shareObject;
//调用分享接口
[[UMSocialManager defaultManager] shareToPlatform:platformType messageObject:messageObject currentViewController:[self getCurrentVC] completion:^(id data, NSError *error) {
if (error) {
[YLAlertViewTool showAlertViewWithTitle:@"分享失败" message:nil cancelBtnTitle:@"确定"];
} else {
[YLAlertViewTool showAlertViewWithTitle:@"分享成功" message:nil cancelBtnTitle:@"确定"];
}
}];
}
好多地方都要用到弹框,就自己封装一下了
+ (void)showAlertViewWithTitle:(NSString *)alertTitle message:(NSString *)msg cancelBtnTitle:(NSString *)cancelBtnTitle
{
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:alertTitle message:msg preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *action = [UIAlertAction actionWithTitle:cancelBtnTitle style:UIAlertActionStyleDefault handler:nil];
[alertController addAction:action];
[[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:alertController animated:YES completion:nil];
}
获取当前的控制器.如果你用这个方法的地方比较多,那么直接写一个类封装一下吧.
- (UIViewController *)getCurrentVC {
UIWindow *window = [[UIApplication sharedApplication].windows firstObject];
if (!window) {
return nil;
}
UIView *tempView;
for (UIView *subview in window.subviews) {
if ([[subview.classForCoder description] isEqualToString:@"UILayoutContainerView"]) {
tempView = subview;
break;
}
}
if (!tempView) {
tempView = [window.subviews lastObject];
}
id nextResponder = [tempView nextResponder];
while (![nextResponder isKindOfClass:[UIViewController class]] || [nextResponder isKindOfClass:[UINavigationController class]] || [nextResponder isKindOfClass:[UITabBarController class]]) {
tempView = [tempView.subviews firstObject];
if (!tempView) {
return nil;
}
nextResponder = [tempView nextResponder];
}
return (UIViewController *)nextResponder;
}
这样就搞定了.来测试一下吧
NSString *strUrl = [NSString stringWithFormat:@"m.51tsg.com/51tsg-classify/product-detail.html?goods_id=%@",self.goods_id];
NSString *imageUrl = self.goodsDetail.goods_image_more[0][@"image_url"];
NSString *title = @"买特产，就来51特色购";
NSString *descr = self.goodsDetail.goods_name;
YLShareFunction *shareFunction = [YLShareFunction share];
[shareFunction shareURL:strUrl image:imageUrl shareTitle:title descr:descr];
效果如下
