nsurlconnection

问题 I have a hard time to find any examples for NSURLConnection delegate method implemenetations. The SeismicXML example from apple is incomplete. For instance, they don't incorporate -connection:willSendRequest:redirectResponse: Maybe there's a good text out there. I went already through all the Apple material regarding this. 回答1: Here's an implementation I've been working with lately: .h: NSMutableData *responseData; .m: - (void)load { NSURL *myURL = [NSURL URLWithString:@""];

问题 I've been fooling around with code for ages on this one, I would be very grateful if someone could provide a code sample that downloaded this file from a server http://www.archive.org/download/june_high/june_high_512kb.mp4, (By the way it's not actually this file, it's just a perfect example for anyone trying to help me) and then play it from the documents directory. I know it seems lazy of me to ask this but I have tried so many different variations of NSURLConnection that it's driving me

问题 I'm POST'ing a small image, so i'd like the timeout interval to be short. If the image doesn't send in a few seconds, it's probably never going to send. For some unknown reason my NSURLConnection is never failing, no matter how short I set the timeoutInterval . // Create the URL request NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.tumblr.com/api/write"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:0.00000001]; /*

问题 I have a ton of repeating code in my class that looks like the following: NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; The problem with asynchronous requests is when you have various requests going off, and you have a delegate assigned to treat them all as one entity, a lot of branching and ugly code begins to formulate going: What kind of data are we getting back? If it contains this, do that, else do other. It would be useful I think to be

问题 I'm trying request a URL parsing parameters with POST, but mypage.php is not receiving this parameters... Here is my code: NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://myurl/mypage.php"]]; NSString *params = [[NSString alloc]initWithFormat:@"name=%@&surname=%@&location=%@&email=%@&password=%@&gender=%@&tipo=%@", name, surname, location, email, password, gender, tipo]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:[params

问题 In an application having UITabBarController , I want to implement following scenario: When user is on 'X' Tab , he/she does something & then move to another tabs. And again he/she comes back to 'X' tab( say after 5minutes-> this is important as I may change 5min to 10min in future ), then I want to show some message like your 'Session is expired'. Whenever user comes back 'X' Tab, it need to make server request to get response code. Depending upon that I want to show the pop-up 'Session is

问题 I have my local data in json file like : { "locations": [ { "title": "The Pump Room", "place": "Bath", "latitude": 51.38131, "longitude": -2.35959, "information": "The Pump Room Restaurant in Bath is one of the city’s most elegant places to enjoy stylish, Modern-British cuisine.", "telephone": "+44 (0)1225 444477", "visited" : true }, { "title": "The Eye", "place": "London", "latitude": 51.502866, "longitude": -0.119483, "information": "At 135m, the London Eye is the world’s largest

问题 I am working through through the basics of Objective-C, I've graduated past syntax but I'm still not doing any ios specific stuff. Anyway, I'm trying to figure out http requests, and I can't get an asynchronous post to work correctly. I can go very basic (this works): NSString *doc = [NSString stringWithContentsOfURL:url usedEncoding:&encoding error:&error]; NSLog(@"%@", doc); And I can make a synchronous request (also works): NSData *urlData = [NSURLConnection sendSynchronousRequest
