既然知道了我们可以自己构造scheme url打开其他App，并完成对应的业务操作。那么我们来试试，不适用SDK的情况下，完成分享信息到QQ和QZone.
首先，假设我们做成一个标准，任何遵循我们这个标准都可以被我们直接拿来使用，将数据分享到对应的平台。Ok，我们先定义一个分享的标准Api接口。
/**
* 所有分享平台必须实现的规范
*/
@protocol ShareInterface <NSObject>
@required
//分享平台的关键字
- (NSString *)platformName;
//分享平台的类型
- (XZHSharePlatform)platformType;
//secret是可选
- (void)registWithAppIdOrAppKey:(NSString *)keyOrId
AppSecret:(NSString *)secret;
//分享
- (void)startShare:(XZHMessage *)message Type:(XZHShareType)shareType;
- (BOOL)handleOpenURL;
@optional
//授权
- (void)oauth;
- (BOOL)isInstalled;
@end
定义完接口后，我们开始做一个分享到腾讯平台的接口实现。
//.h #import <Foundation/Foundation.h> #import "XZHShareBase.h" //注： XZHShareBase类默认实现了接口，并提供了一些基础代码 @interface XZHShareToQQ : XZHShareBase @end
//.m
- (NSString *)platformName {
return @"QQ";
}
- (XZHSharePlatform)platformType {
return XZHShareQQ;
}
/**
* 把传入的appKey和appSecret使用单例对象保存起来，方便后面使用
*/
- (void)registWithAppIdOrAppKey:(NSString *)keyOrId AppSecret:(NSString *)secret {
//保存参数
NSDictionary *options = @{
@"appid" : keyOrId,
@"callback_name" : [NSString stringWithFormat:@"QQ%02llx",[keyOrId longLongValue]]
};
[self saveOptions:options];
}
/**
* 分享信息的核心方法：
* 1. 根据不同的分享Api，构造不同的scheme url
* 2. 构造完scheme url后，openURL打开url，掉起QQ
*/
- (void)startShare:(XZHMessage *)message Type:(XZHShareType)shareType
{
NSString *url = @"";
if (shareType == XZHShareToQZone) {
