mySQL database to iPhone app

由 纵然是瞬间 提交于 2019-12-06 12:52:42
问题 I have a MySQL database on a web server and need to read the data from an iPhone app. What is the best way to do this? The data needs to be accessed from the web server and will be updated from time to time. Is the NSURL Class the way to go? thanks for any help. 回答1: I suggest a simple web technology on the server side -- PHP, Ruby on Rails, etc. -- that acts as a basic RESTful-ish web service that sends out JSON. This is straightforward and doesn't require a lot of programming expertise --

问题 I am downloading a bunch of largish zip files with the following method. It can take a little while and so I'd like to display a progress bar. I've researched how to do with with the delegate methods for NSURLConnection and it seems straightforward, however I want to achieve the same thing with "sendAsynchronousRequest". How can I get the number of bytes downloaded as it downloads as well as the total number of bytes expected so that I can display a progress bar? I understand that I cannot

Test NSURLConnection failure

How can you test a failure of NSURLConnection? Also, how do you tell if it failed due to airplane mode or WiFi being turned off? In my tests, while the alert pops up telling the user they need to turn on WiFi, if they ignore it my App just sits there and spins waiting for a response. If your connection's delegate is self, you can something like this: self.myConnection = [[[NSURLConnection alloc] initWithRequest:urlRequest delegate:self] autorelease]; - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { if ([error code] == kCFURLErrorNotConnectedToInternet) { //

Thanks a lot for reply. I am stuck here. Can you please help with this situation? Can CFHTTPStream will resolve this problem? Is there any other way to work with this problem ? Thanks. Hi, I am connecting to an HTTP url using NSURLConnection. I am supposed to get response after some time intervals (The response is not getting closed from server). Is it possible to read those responsed whenever they are written just like having an infinite while loop on input stream of http url connection in java. The didReceiveData method is not getting called. Consider it as an http push where response will
