如何在objective C中缩短URL

Question

我找到了几个缩短URL的例子。但他们没有一个对我不起作用。如果谁有工作的例子，请分享。我试过的是，

 NSString *apiEndpoint = [NSString stringWithFormat:@"http://tinyurl.com/api-create.php?url=%@",strUrl];
NSString *shortURL = [NSString stringWithContentsOfURL:[NSURL URLWithString:apiEndpoint]
                                              encoding:NSASCIIStringEncoding
                                                 error:nil];
NSLog(@"Long: %@ - Short: %@",strUrl,shortURL);

NSString *shortenedURL = [NSString stringWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://api.bit.ly/v3/shorten?login=%@&apikey=%@&longUrl=%@&format=txt", @"smartsanja@gmail.com", @"R_2db6e96aad348b8c993acf6ba80884c4", strUrl]] encoding:NSUTF8StringEncoding error:nil];

NSLog(@"Shoted url %@", [shortenedURL JSONValue]);

试着使用下面的代码来获得简短的url。

1.先试试这个..

NSString *urlstr = yourURL ;///here put your URL in string
[urlstr retain];
NSString *apiEndpoint = [NSString stringWithFormat:@"http://ggl-shortener.appspot.com/?url=%@",urlstr];
[apiEndpoint retain];

NSLog(@"\n\n APIEndPoint : %@",apiEndpoint);
NSString *shortURL = [NSString stringWithContentsOfURL:[NSURL URLWithString:apiEndpoint]
                                              encoding:NSASCIIStringEncoding
                                                 error:nil];
shortURL = [shortURL stringByReplacingOccurrencesOfString:@"{\"short_url\":\"" withString:@""];
shortURL = [shortURL stringByReplacingOccurrencesOfString:@"\",\"added_to_history\":false}" withString:@""];
[shortURL retain];
NSLog(@"Long: %@ - Short: %@",urlstr,shortURL);

2.第二种方法如下

NSString *urlstr =[yourURL stringByReplacingOccurrencesOfString:@" " withString:@""];///your url string 
            [urlstr retain];
            NSString *apiEndpoint = [NSString stringWithFormat:@"http://tinyurl.com/api-create.php?url=%@",urlstr];
            [apiEndpoint retain];

            NSLog(@"\n\n APIEndPoint : %@",apiEndpoint);
            NSString *shortURL = [NSString stringWithContentsOfURL:[NSURL URLWithString:apiEndpoint]
                                                          encoding:NSASCIIStringEncoding
                                                             error:nil];
[shortURL retain];
    NSLog(@"Long: %@ - Short: %@",urlstr,shortURL);

希望这能帮到你。

This NSURL category of mine直接返回一个缩写的NSURL。

试试这个吧，我觉得挺好的。

NSString *apiEndpoint = [NSString stringWithFormat:@"http://tinyurl.com/api-create.php?url=%@",shareUrlString]; // The shareUrlString is NSString, which having URl

shortenUrl = [NSString stringWithContentsOfURL:[NSURL URLWithString:apiEndpoint] encoding:NSASCIIStringEncoding error:nil]; //ShortenUrl is NSString
