如何使用 ios 中的子字符串拆分 url？

Question

如何用 / 字符拆分 URL？

例如，

www.whosebug.com/questions

我想在上面的/之后拆分URL得到/questions

Answer 1

这可能对你有帮助。

NSString *url = @"www.whosebug.com/questions";
NSArray *items = [url componentsSeparatedByString:@"/"];

NSString *str1=[items objectATindex:0];   //www.whosebug.com
NSString *str2=[items objectATindex:1];   //questions

Answer 2

在 NSURL 对象上使用 pathComponents 属性。

This property contains an array containing the individual path components of the URL, each unescaped using the stringByReplacingPercentEscapesUsingEncoding: method. For example, in the URL file:///directory/directory%202/file, the path components array would be @[@"/", @"directory", @"directory 2", @"file"].

NSURL *myUrl = [NSURL URLWithString:@"www.whosebug.com/questions"];
NSString *lastPathComponent = [myUrl lastPathComponent]; // "questions"
NSArray *pathComponents = [myUrl pathComponents]; // <__NSArrayM 0x7fc45b649df0>( www.whosebug.com, questions )

要删除 http://，请使用 host 属性:

NSURL *myUrl = [NSURL URLWithString:@"http://www.whosebug.com/questions"];
NSString *host = myUrl.host; // whosebug.com
