首先附上源码：Jozo的Github -- JZShare
当我们用ShareSDK集成分享的功能，难免会遇到产品提来的需求，他会找设计自行设计出一套UI，然后指着那美轮美奂的效果告诉你，做成这样。
那么，怎样抛弃Mob原生的UI，来自行定义UI呢，其实也很简单。SDK里本来就有摒弃UI的调用分享的方法。本文的一切也将围绕它展开。
本文使用Mob版本为ShareSDK For iOS v3.3.0
/**
* 分享内容
*
* @param platformType 平台类型
* @param parameters 分享参数
* @param stateChangeHandler 状态变更回调处理
*/
+ (void)share:(SSDKPlatformType)platformType
parameters:(NSMutableDictionary *)parameters
onStateChanged:(SSDKShareStateChangedHandler)stateChangedHandler;
下面开始正式的代码实现：
首先自定义一个类 "ShareCustom"
ShareCustom.h
#import <Foundation/Foundation.h>
@interface ShareCustom : NSObject
+(void)shareWithContent:(id)publishContent;//自定义分享界面
ShareCustom.m
// 适配
#define DevicesScale ([UIScreen mainScreen].bounds.size.height==480?1.00:[UIScreen mainScreen].bounds.size.height==568?1.00:[UIScreen mainScreen].bounds.size.height==667?1.17:1.29)
// 颜色
#define UIColorFromRGB(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0 blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]
// 获取屏幕尺寸
#define kScreenHeight ([UIScreen mainScreen].bounds.size.height)
#define kScreenWidth ([UIScreen mainScreen].bounds.size.width)
// 设备类型
#define SYSTEM_VERSION [[UIDevice currentDevice].systemVersion floatValue]
//屏幕宽度相对iPhone6屏幕宽度的比例
#define KWidth_Scale [UIScreen mainScreen].bounds.size.width/375.0f
#import "JZShareCustom.h"

@end
可以直接拷贝以上代码，然后飘红的地方稍加修改即可
然后在需要调用分享的地方调用以下方法就可以自定义分享UI啦，当然你也可以在文章上方的源码Demo里自己体会，十分简单
#pragma mark - Private Method
- (void)goShare {
//1、创建分享参数
NSArray* imageArray = @[[UIImage imageNamed:@"share_icon"]];
if (imageArray) {
NSMutableDictionary *shareParams = [NSMutableDictionary dictionary];
[shareParams SSDKSetupShareParamsByText:@"IM/音视频/呼叫中心/电话会议等通讯能力全方位展示，实力派，很任性。"
images:imageArray
url:[NSURL URLWithString:@"http://113.31.88.170:8081/cfct-server/demo/demo.html?to=UC_DEMO"]
title:@"云之讯UC"
type:SSDKContentTypeAuto];
//调用自定义分享
[ShareCustom shareWithContent:shareParams];
}
}
That's all, thank you.
