简介

这段时间有很多朋友都问我关于怎么去集成ShareSDK或者友盟社会化分享SDK的问题, 其实我想说, Apple一开始就提供了一个类, 供我们去使用分享了, 在iOS 6之后更加增强了这个类, 使我们不再需要集成第三方的, 而且还支持自定义分享的item.


作者感言

在我写这篇文章的时候, 虽然国内有一堆文章介绍UIActivityViewControllerUIActivity, 但都是零零散散的, 哪怕我翻墙出去看YouTube, 或者是著名的黑胡子博客, 都没有详细的讲解怎么去自定义所需的UIActivity, 最后基本上翻遍了谷歌, 才找到了所需的.

最后:如果你有更好的建议或者对这篇文章有不满的地方, 请联系我, 我会参考你们的意见再进行修改, 联系我时, 请备注UIActivityViewController 如果觉得好的话, 希望大家也可以打赏一下~嘻嘻~祝大家学习愉快~谢谢~

这时候我们就要来给这个自定义的UIActivity类写上我们需要的内容, 首先我们可以去到系统提供的UIActivity头文件看API, 获取我们所需的API.

这里和大家说说excludedActivityTypes这个属性, 这个属性其实是一个数组属性, 代表的是, 如果我们不需要系统的服务就可以给它赋值, 这样子UIActivityViewController就不会显示对应的服务, 我这里默认全部干掉, 一个服务都不需要, 当然如果需要干掉我们自定义的UIActivity, 也可以在这里写上.

还有一点, 就是我们给UIActivityViewController赋值自定义的UIActivity

PS: 注意一点, 这个赋值只能在initWithActivityItems: applicationActivities:这个方法的applicationActivities:赋值, 而且只能在初始化的时候赋值, 一旦赋值之后就不能再修改了.


调起UIActivityViewController

最重要的地方来了, 就是调起我们自定义的UIActivityController.

首先我们要在Main.storyboard中拖一个UIButton, 然后添加对应的代码.

代码:

#import "ViewController.h"
#import "UIActivityController.h"
@interface ViewController ()
@property (nonatomic, strong) UIActivityController *activityController;
@end
@implementation ViewController
- (IBAction)popActivityController:(UIButton *)sender {      
   [self presentViewController:self.activityController animated:YES completion:nil];
}
- (UIActivityController *)activityController {      
   NSString *shareTitle = @"分享的标题";    
   UIImage *shareImage = [UIImage imageNamed:@"ShareBundle.bundle/share_icon_1"];      
   if (!_activityController) {          
       _activityController = [[UIActivityController alloc] initAspActivityControllerWithContent:@[shareTitle, shareImage]];    
   }      
   return _activityController; }
@end
 

最后我们运行一下看看效果

好了, item出来了, 但好像有什么不对, 图标呢???!!! 为啥是灰色的? 楼主你耍我, 我要去爆你菊花!!!!!

别紧张, 在系统默认的UIActivityViewController中, 下面这部分是属于系统服务, 默认只会显示一个轮廓, 并不会显示整张图片, 下面我们把自定义的WeiboActivity显示图片的方法改改就好了.

好了, 我的菊花保住了, 图标出来了, 把我吓了一身冷汗

图标出来了, 我们就要给这个item添加点击事件了, 做什么好呢, 总不可能让我去导个微信微博等SDK进来演示, 毕竟还要去申请AppIDAppKey呢, 我们来个弹框吧~~~

我一般喜欢写个Block把点击事件抛出去做处理, 这次我也不例外~~
