起初我只是使用GET
方法向服务器发送数据,我收到如下响应
2015-11-16 14:21:42.168 smartschool[1963:348015] Item actcode: ZQRTNN68
2015-11-16 14:21:42.169 smartschool[1963:348015] Item parentid: 8
如何将激活码显示到下一个 viewController
的标签。
这是我的代码:
#import "RegistrationViewController.h"
@interface RegistrationViewController ()
@end
@implementation RegistrationViewController
{
NSMutableData *mutableData;
#define URL @"http://192.168.1.166/bustracking/activation/requestActivationCode"
}
- (void)viewDidLoad
{
[super viewDidLoad];
}
-(IBAction)sendDataUsingGet:(id)sender{
[self sendDataToServer : @"GET"];
}
-(void) sendDataToServer : (NSString *) method
{
NSString *parentName = parent_name.text;
NSString *contactNumber = contact_number.text;
NSString *beaconid = @"145801000095";
//NSString *beaconMacAdd = @"14:58:01:00:00:95";
if(parentName.length > 0 && contactNumber.length > 0){
NSLog (@"Getting response from server...");
NSMutableURLRequest *request = nil;
// Only Difference between POST and GET is only in the way they send parameters
if([method isEqualToString:@"GET"]){
NSString *getURL = [NSString stringWithFormat:@"%@?parent_name=%@&contact_number=%@&beacon_id=%@", URL, parentName, contactNumber, beaconid];
//url = [NSURL URLWithString: getURL];
getURL = [getURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString: getURL];
request = [NSMutableURLRequest requestWithURL:url];
NSLog(@"urlinfo: %@", url);
NSLog(@"link: %@", getURL);
}
[request setHTTPMethod:method];
[request addValue: @"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
NSLog(@"connection: %@", connection);
if( connection )
{
mutableData = [NSMutableData new];
}
else
{
NSLog (@"NO_CONNECTION");
return;
}
}
else
{
NSLog(@"NO_VALUES");
}
}
#pragma mark NSURLConnection delegates
-(void) connection:(NSURLConnection *) connection didReceiveResponse:(NSURLResponse *)response
{
[mutableData setLength:0];
}
-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[mutableData appendData:data];
}
-(void) connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog (@"NO_CONNECTION");
return;
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSError *error = nil;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:mutableData options:kNilOptions error:&error];
NSArray *fetchedArr = [json objectForKey:@"response"];
NSString *responseActCode;
for (NSDictionary *user in fetchedArr)
{
responseActCode = [user objectForKey:@"activation_code"];
NSLog(@"Item actcode: %@", responseActCode);
NSLog(@"Item parentid: %@", [user objectForKey:@"parent_id"]);
//NSLog(@"Item actcode: %@", [user objectForKey:@"activation_code"]);
}
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:responseActCode forKey:@"HighScore"];
[defaults synchronize];
NSLog(@"from data: %@", [defaults objectForKey:@"HighScore"]);
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:@"Activation Code"
message:(@"%@", responseActCode)
delegate:nil //or self
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
}
@end
最佳答案
如果返回的数据是字典格式,在header.h类中声明nsdictionary,你想传数据,同样可以用array和string,现在如果你用的是storyboard,方法如下。
p>- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
// Make sure your segue name in storyboard is the same as this line
if ([[segue identifier] isEqualToString:@"YOUR_SEGUE_NAME_HERE"])
{
// Get reference to the destination view controller
YourViewController *vc = [segue destinationViewController];
// Pass any objects to the view controller here, like...
vc.dictionary = self.dictionary.
}
}
如果您想在点击手机时传输数据,这就是您必须要做的。
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:@"YOUR_SEGUE_NAME_HERE"" sender:self];
}
当调用“performSegueWithIdentifier”时,该方法自动重定向到“prepareForSegue”方法:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
NSIndexPath *indexPath= [self.tableView indexPathForSelectedRow];
// Make sure your segue name in storyboard is the same as this line
if ([[segue identifier] isEqualToString:@"YOUR_SEGUE_NAME_HERE"])
{
// Get reference to the destination view controller
YourViewController *vc = [segue destinationViewController];
// Pass any objects to the view controller here, like...
now this time its array.
vc.array= [array[indexpath.row] valueforkey@"jsonkey"];
}
}
关于ios - 将 json 响应传递给 iOS 中的另一个 View Controller ,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/33729712/
