Question

我开发搜索类似图像的程序（反向图像搜索）我的代码：

Y_request = [[NSMutableURLRequest alloc]init];
[Y_request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[Y_request setHTTPShouldHandleCookies:NO];
[Y_request setTimeoutInterval:30];
[Y_request setHTTPMethod:@"POST"];


NSString *Y_boundary=@"myBoucndary";
NSString *Y_FileParamConstant=@"upfile";
Y_requestURL = [[NSURL alloc]initWithString:@"https://www.yandex.com/images/search"];

NSString *Y_contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",Y_boundary];
[Y_request setValue:Y_contentType forHTTPHeaderField:@"Content-Type"];

Y_body = [NSMutableData data];



NSDictionary *Y_params=@{
                         @"format":@"",
                         @"request":@"[{\"block\":\"b-page_type_search-by-image__link\"}]",
                         @"rpt":@"imageview"
                         };
for (NSString *Y_param in Y_params) {
    [Y_body appendData:[[NSString stringWithFormat:@"--%@\r\n",Y_boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [Y_body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", Y_param] dataUsingEncoding:NSUTF8StringEncoding]];
    [Y_body appendData:[[NSString stringWithFormat:@"%@\r\n", [Y_params objectForKey:Y_param]] dataUsingEncoding:NSUTF8StringEncoding]];
}

//添加图片数据

NSData *Y_imageData = UIImageJPEGRepresentation(imageSearch, 0.1);
if (Y_imageData) {
    [Y_body appendData:[[NSString stringWithFormat:@"--%@\r\n", Y_boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [Y_body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"image\"; filename=\"image.jpeg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [Y_body appendData:[@"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [Y_body appendData: Y_imageData];
    [Y_body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

}
[Y_body appendData:[[NSString stringWithFormat:@"--%@--\r\n", Y_boundary] dataUsingEncoding:NSUTF8StringEncoding]];


[Y_request setHTTPBody:Y_body];
[Y_request  setURL:Y_requestURL];
[_myWebView loadRequest:Y_request];

此Yandex搜索查询。此查询仅适用于iPhone，但不适用于Ipad，为什么？谢谢你的回答。

目标-c POST请求无效
