Creating URL query parameters from NSDictionary objects in ObjectiveC

由 徘徊边缘 提交于 2019-11-26 03:44:42
With all the URL-handling objects lying around in the standard Cocoa libraries (NSURL, NSMutableURL, NSMutableURLRequest, etc), I know I must be overlooking an easy way to programmatically compose a GET request. Currently I'm manually appending "?" followed by name value pairs joined by "&", but all of my name and value pairs need to be manually encoded so NSMutableURLRequest doesn't fail entirely when it tries to connect to the URL.

由 无人久伴 提交于 2019-11-26 02:30:22
问题 I\'ve seen many questions on SO concerning converting between NSURL and NSString . They all involve using either NSString *path = [myURL absoluteString]; or NSString *path = [myURL path]; . What is the actual difference between these methods? Is there a time when one should be used over the other? I tried consulting the Apple Docs, but I found it less than helpful. I\'m used to URL\'s only being mentioned in discussions concerning websites and other topics regarding sending information

How do I load an HTTP URL with App Transport Security enabled in iOS 9? [duplicate]

问题 This question already has an answer here: Transport security has blocked a cleartext HTTP 25 answers So, the new beta SDK of iOS released last night has \"App Transport Security\" which encourages developers to use https instead of http. In principle, this is a great idea, and I already use https in our staging/production environments. However, I don\'t have https set up in my local development environment, when the iOS app is connecting to a web service I\'m running on my laptop. From a bit
