无法在iOS8上的iTunes Store中搜索 [英] Unable to search in iTunes Store on iOS8

问题描述

我正在使用此代码打开iTunes Store应用并搜索特定音乐：

I'm using this code to open iTunes Store app and search for specific music:

NSString *iTunesLink = [NSString stringWithFormat:@"http://search.itunes.apple.com/WebObjects/MZSearch.woa/wa/search?entity=album&media=all&page=1&restrict=true&startIndex=0&term=TERM_NAME"];
NSURL *url = [NSURL URLWithString:iTunesLink];
[[UIApplication sharedApplication] openURL:url];

代码在iOS7上运行正常，通过更改TERM_NAME值我可以搜索我想要的任何内容。 iOS8上的问题是以某种方式追加搜索词并以（）符号作为前缀。我正在使用日志检查我的NSURL的值是多少但看起来很好。

Code works fine on iOS7, by changing TERM_NAME value I can search whatever I want. The issue on iOS8 is that somehow search term is appended and prepended by ( " ) symbols. I'm using log to check what's the value of my NSURL but it looks fine.

推荐答案

此代码适用于我：

NSString *artist = @"artist";
NSString *title = @"title";

NSOperationQueue *operationQueue = [NSOperationQueue new];
NSString *baseURLString = @"https://itunes.apple.com/search";
NSString *searchTerm = [NSString stringWithFormat:@"%@ %@", artist, title];
NSString *searchUrlString = [NSString stringWithFormat:@"%@?media=music&entity=song&term=%@&artistTerm=%@&songTerm=%@", baseURLString, searchTerm, artist, title];
searchUrlString = [searchUrlString stringByReplacingOccurrencesOfString:@" " withString:@"+"];
searchUrlString = [searchUrlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSURL *searchUrl = [NSURL URLWithString:searchUrlString];

NSURLRequest *request = [NSURLRequest requestWithURL:searchUrl];
[NSURLConnection sendAsynchronousRequest:request queue:operationQueue completionHandler:^(NSURLResponse* response, NSData* data, NSError* error)
 {
     if (error)
     {
         NSLog(@"Error: %@", error);
     }
     else
     {
         NSError *jsonError = nil;
         NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:0 error:&jsonError];

         if (jsonError)
         {
             NSLog(@"JSON Error: %@", jsonError);
         }
         else
         {
             NSArray *resultsArray = dict[@"results"];

             if(resultsArray.count == 0)
             {
                 dispatch_async(dispatch_get_main_queue(), ^{
                     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"917xfm" message:[NSString stringWithFormat:@"No results returned."] delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
                     [alert show];
                     [alert release];
                 });
             }
             else
             {
                 NSDictionary *trackDict = resultsArray[0];
                 NSString *trackViewUrlString = trackDict[@"trackViewUrl"];

                 if (trackViewUrlString.length)
                 {
                     NSURL *trackViewUrl = [NSURL URLWithString:trackViewUrlString];

                     dispatch_async(dispatch_get_main_queue(), ^{
                         [[UIApplication sharedApplication] openURL:trackViewUrl];
                     });
                 }
             }
         }
     }
 }];
