将timeoutInterval设置为无限

Question

我真的不想要一个timeoutInterval，所以当离线时缓存总是可用的，但是我也不能忽略它。有办法把它设为无限吗？

var requestObj = NSURLRequest(URL: url!, cachePolicy: NSURLRequestCachePolicy.ReturnCacheDataElseLoad, timeoutInterval: 5);

Answer 1

简单

var requestObj = NSURLRequest(URL: url!, cachePolicy: NSURLRequestCachePolicy.ReturnCacheDataElseLoad, timeoutInterval: Double.infinity);

Answer 2

var requestObj = NSURLRequest(URL: url!，cachePolicy: NSURLRequest timeoutInterval: Double.greatestFiniteMagnitude)
