最簡易方法呼叫淘寶app：

引用檔案
#import <AlibcTradeSDK/AlibcTradeSDK.h>



    AlibcWebViewController* view = [[AlibcWebViewController alloc] init];

    AlibcTradeShowParams* showParam = [[AlibcTradeShowParams alloc] init];
    showParam.openType = AlibcOpenTypeNative;
    //8位數appkey
    showParam.backUrl
 
[email protected]"tbopenxxxxxxxx://";    showParam.isNeedPush=YES;
    showParam.nativeFailMode=AlibcNativeFailModeJumpH5;
    id<AlibcTradePage> page = [AlibcTradePageFactory page: _model.taobao_url];

//    0:  標識跳轉到手淘打開了
//    1:  標識用h5開啟
//    -1:  標識出錯
    NSInteger ret =[[AlibcTradeSDK sharedInstance].tradeService
 
 show:self webView:view.webView page:page showParams:showParam taoKeParams:nil trackParam:nil tradeProcessSuccessCallback:nil tradeProcessFailedCallback:nil];
    NSLog(@"ret-----%ld",ret);
    if (ret == 1) {
        [self.navigationController pushViewController:view animated:YES];
    }

iOS不支援V5圖片，只支援V4 圖片吐槽一下文件未能註明

這樣下載下來的安全圖片放到專案中才不會報錯
