我正在开发一个连接到Rest API的应用程序,目前为止我只使用以下代码进行了GET请求:
//Start login process
NSString *emailstring = email.text;
NSString *passstring = pass.text;
// Create the URL from a string.
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://www.myserver.com/Rest/API/users?format=json&email=%@&password=%@",emailstring,passstring]];
NSLog(@"%@",url);
// Create a request object using the URL.
NSURLRequest *request = [NSURLRequest requestWithURL:url];
// Prepare for the response back from the server
NSHTTPURLResponse *response = nil;
NSError *error = nil;
// Send a synchronous request to the server (i.e. sit and wait for the response)
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(@"Reponse from web:%@", response);
// Check if an error occurred
if (error != nil) {
NSLog(@"%@", [error localizedDescription]);
// Do something to handle/advise user.
UIAlertView *message = [[UIAlertView alloc] initWithTitle:@"Login error"
message:@""
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[message show];
}
else {
// Convert the response data to a string.
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
// View the data returned - should be ready for parsing.
NSLog(@"%@", responseString);
// Add data to a Plist file for next time
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"login.plist"];
NSArray *values = [[NSArray alloc] initWithObjects:emailstring,passstring,@"IDtest",nil];
[values writeToFile:path atomically:YES];
[values release];
[self dismissModalViewControllerAnimated:YES];
}
这段代码只适用于GET请求。我看到有很多框架(例如RestKit等),但是对于其他请求我有点迷失!那么,为iOS应用程序进行POST DELETE PUT请求的最佳解决方案是什么?
