【问题描述】:
我正在使用下面的代码,但它对我不起作用并且总是得到空响应,但是当该 URL 害虫进入浏览器时,它会下载一个包含以下文本的 f.txt 文件
window.google.ac.h(["Y",[["young thug",0],["youtube",0],["youth troye sivan",0],["young dolph",0],["yo gotti",0],["yg",0],["yoga",0],["you 应该在这里 cole swindell",0],["yandere 模拟器",0],["young thug 最好的朋友",0]],{"k":1,"l":"1","q":"Fu65vJmwPDpRvrCvJ_hO3MqI15U"}])
@property(strong, nonatomic) NSMutableArray *ParsingArray // Put that in .h file or after @interface in your .m file
-(void)autocompleteSegesstions : (NSString *)searchWish{
//searchWish is the text from your search bar (self.searchBar.text)
NSString *jsonString = [NSString stringWithFormat:@"http://suggestqueries.google.com/complete/search?client=youtube&ds=yt&alt=json&q=%@", searchWish];
NSString *URLString = [jsonString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; // Encoding to identify where, for example, there are spaces in your query.
NSLog(@"%@", URLString);
NSData *allVideosData = [[NSData alloc]initWithContentsOfURL:[[NSURL alloc]initWithString:URLString]];
NSString *str = [[NSString alloc]initWithData:allVideosData encoding:NSUTF8StringEncoding];
NSLog(@"%@", str); //Now you have NSString contain JSON.
NSString *json = nil;
NSScanner *scanner = [NSScanner scannerWithString:str];
[scanner scanUpToString:@"[[" intoString:NULL]; // Scan to where the JSON begins
[scanner scanUpToString:@"]]" intoString:&json];
//The idea is to identify where the "real" JSON begins and ends.
json = [NSString stringWithFormat:@"%@%@", json, @"]]"];
NSLog(@"json = %@", json);
NSArray *jsonObject = [NSJSONSerialization JSONObjectWithData:[json dataUsingEncoding:NSUTF8StringEncoding] //Push all the JSON autocomplete detail in to jsonObject array.
options:0 error:NULL];
self.ParsingArray = [[NSMutableArray alloc]init]; //array that contains the objects.
for (int i=0; i != [jsonObject count]; i++) {
for (int j=0; j != 1; j++) {
NSLog(@"%@", [[jsonObject objectAtIndex:i] objectAtIndex:j]);
[self.ParsingArray addObject:[[jsonObject objectAtIndex:i] objectAtIndex:j]];
//Parse the JSON here...
}
}}
