iOS 自定义分享功能（分享到微博等sahreSDK）

本次教程是参照官方的shareSDK进行操作（按照教程进行前期的准备操作，该导入的导入，该添加的添加）

做完前期准备工作然后进行下面的操作

首先要对需求的分享方式进行声明

/**
*  分享方式的声明引用
*/
[ShareSDK registerApp:@"3df7a36158b2"];
[ShareSDK connectSinaWeiboWithAppKey:@"568898243"
appSecret:@"38a4f8204cc784f81f9f0daaf31e02e3"
redirectUri:@"http://www.sharesdk.cn"];

选择分享的途径以及制定分享的内容

//选择分享的途径

switch (sender.tag) {

case 11:
type = ShareTypeYiXinSession;
break;
case 12:
type = ShareTypeYiXinTimeline;
break;
case 13:
type = ShareTypeWeixiSession;
break;
case 14:
type = ShareTypeWeixiTimeline ;
break;
case 15:
type = ShareTypeSinaWeibo;
break;
case 16:
type = ShareTypeQQ ;
break;
case 17:
type =  ShareTypeQQSpace;
break;
case 18:
type = ShareTypeRenren;
break;
case 19:
type = ShareTypeSMS;
break;
case 20:
type = ShareType163Weibo;
break;
case 21:
type = ShareTypeTencentWeibo;
break;
case 22:
type = ShareTypeEvernote;
break;
case 23:
type = ShareTypeInstapaper;
break;
case 24:
type = ShareTypeMail;
break;
case 25:
type = ShareTypeYouDaoNote;
break;
case 26:
type = ShareTypePocket;
break;

default:
break;
}
//分享内容等参数的制定
id<ISSContent> publishContent = [ShareSDK content:userWriteTextView.text defaultContent:nil image:[ShareSDK pngImageWithImage:shareImage] title:@"This is title" url:@"http://mob.com" description:@"This is description" mediaType:SSPublishContentMediaTypeNews];
//2.分享
[ShareSDK shareContent:publishContent  type:type  authOptions:nil  shareOptions:nil  statusBarTips:YES
result:^(ShareType type, SSResponseState state, id<ISSPlatformShareInfo> statusInfo, id<ICMErrorInfo> error, BOOL end) {
if (state == SSPublishContentStateSuccess){
NSLog(@"分享成功");
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"" message:@"分享成功" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
} else if (state == SSPublishContentStateFail){
NSLog(@"分享失败,错误码:%ld,错误描述%@",(long)[error errorCode],[error errorDescription]);
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"" message:@"分享失败，请看日记错误描述" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
}
}];
}

下面的这个方法是判断用户是否登录的

</pre><pre name="code" class="objc"> id<ISSPlatformCredential> credential = [ShareSDK getCredentialWithType:ShareTypeSinaWeibo];
if(credential!=nil&&[credential available]){
NSLog(@"处在登录状态！");
}else {
NSLog(@"未处在登录状态！");
}
