如何将在不同文本字段中输入的值存储到目标C中的服务器中，在我的项目中，我创建了一个表单，其中包含不同的文本字段，用户必须在文本字段中输入值，我保留了一个SAVE按钮，在输入文本字段的值后，用户必须单击“保存”按钮。
我必须在点击SAVE按钮时将输入文本字段的值保存到服务器。
所以如何在点击SAVE按钮时将数据或值保存到服务器。
以下是我用来创建表单的代码，
在.h文件中：
#import <UIKit/UIKit.h>
#import "PickerViewController.h"
@interface PopAppViewController : UIViewController < NumberPickedDelegate>{
UIPopoverController *popOverController;
UIPopoverController *popOverControllerWithPicker;
PickerViewController *pickerViewController;
IBOutlet UITextField *txtTest;
IBOutlet UITextField *txtSun;
IBOutlet UITextField *txtMon;
IBOutlet UITextField *txtTue;
IBOutlet UITextField *txtWed;
IBOutlet UITextField *txtThurs;
IBOutlet UITextField *txtFri;
IBOutlet UITextField *txtSat;
IBOutlet UITextField *txtTotal;
IBOutlet UITextField *txtTask;
IBOutlet UITextField *txtProject;
}
@property (nonatomic, retain) UIPopoverController *popOverController;
@property (nonatomic, retain) UIPopoverController *popOverControllerWithPicker;
@property (nonatomic, retain) PickerViewController *pickerViewController;
@property (nonatomic, retain) UITextField *txtTest;
@property (nonatomic, retain) UITextField *txtSun;
@property (nonatomic, retain) UITextField *txtMon;
@property (nonatomic, retain) UITextField *txtTue;
@property (nonatomic, retain) UITextField *txtWed;
@property (nonatomic, retain) UITextField *txtThurs;
@property (nonatomic, retain) UITextField *txtFri;
@property (nonatomic, retain) UITextField *txtSat;
@property (nonatomic, retain) UITextField *txtTotal;
@property (nonatomic, retain) UITextField *txtTask;
@property (nonatomic, retain) UITextField *txtProject;
-(IBAction)displayPickerPopover;
-(IBAction)exit;
-(IBAction)reset;
-(IBAction)save;
-(IBAction)total;
@end
在.m文件中：

您需要将数据编译为JSON字符串，然后使用NSURLRequest
-(IBAction)save
{
// build JSON string
NSDictionary *postDictionary = [NSDictionary dictionaryWithObjectsAndKeys:self.txtTest.text, @"test",
self.txtSun.text, @"sun",
self.txtSun.text, @"mon",
nil];
NSData *postData = [NSJSONSerialization dataWithJSONObject:postDictionary options:NSJSONWritingPrettyPrinted error:NULL];
// perform http request (on a background thread)
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(queue, ^{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:@"http://example.com/save.php" cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:postData];
NSHTTPURLResponse *urlResponse = nil;
NSError *error = NULL;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];
// and now go back to the main thread
dispatch_async(dispatch_get_main_queue(), ^{
NSAutoreleasePool *mainQueuePool = [[NSAutoreleasePool alloc] init];
// debug: print response
NSLog(@"%@", [[NSString alloc] initWithData:responseData encoding:NSISOLatin1StringEncoding]);
// check for http error (this includes php exceptions)
if ([urlResponse statusCode] != 200) {
NSLog(@"save failed with status code != 200");
return;
}
[mainQueuePool release];
});
[pool release];
});
}
在你的php中：
$rawData = file_get_contents("php://input");
$postData = json_decode($rawData);
print_r($postData);

由于Objective-C支持纯C，您可以使用类似here描述的C库连接到MySQL服务器。
