Question

我正在尝试从URL创建一个字符串，但URL为null。该字符串确实包含一些内容，但URL仍为空。

以下是我创建网址的位置：

NSData *stringData = feed.urlString;
NSString *stringForURL = [[NSString alloc] initWithData:stringData encoding:NSUTF8StringEncoding];
NSLog(@"Here is the string before being turned into a URL: %@", stringForURL);
NSURL *finalURL = [[NSURL alloc] initWithString:[stringForURL stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]];
finalURL = details.finalURL;

NSLog(@"Here is the final URL: %@", finalURL);

Answer 1

将您的最终网址代码更改为： -

  Nstring *finalURL = [NSURL URLWithString:
   [stringForURL 
 stringByAddingPercentEscapesUsingEncoding:
 NSUTF8StringEncoding]];

string中的URL为null
