可可:获取Mime类型的网址？

Question

我想同步得到一个网址的Mime类型.我不想使用NSURLConnection.就像这样:

NSString*theMimeType = [self getMimeTypeFromURL:theURL];

有任何想法吗？

Answer 1

绝对没有理由不使用异步请求.

使用NSURLConnection委托方法.

NSString        *url  = ...;
NSURLRequest    *req  = [NSURLRequest requestWithURL:[NSURL URLWithString:url]];
NSURLConnection *conn = [NSURLConnection connectionWithRequest:req delegate:self];
[conn start];

在你的其他地方@implementation:

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {

   NSString *mime = [response MIMEType];
   //do something with mime
}
