【问题描述】：

我正在做一个项目，我必须将用户的详细信息发送到服务器以在应用程序中注册。我已经完成了 UI，但无法找到如何向用户发送姓名、电话号码、地址等详细信息的解决方案。我需要有人从一开始就指导我完成整个过程。后端已经写好了，是用PHP写的。

【解决方案1】：

如果您已经编写了后端，您可以在 iOS 7 中通过NSURLSession 向服务器发送数据并返回。下面的示例将以 JSON 格式向服务器发送用户名和密码。

NSError *error;

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURL *url = [NSURL URLWithString:@"URL to which you want to send data"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
                                                       cachePolicy:NSURLRequestUseProtocolCachePolicy
                                                   timeoutInterval:60.0];

[request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request addValue:@"application/json" forHTTPHeaderField:@"Accept"];

[request setHTTPMethod:@"POST"];
NSDictionary *data =@{"userName":"Abc","password","xyz"}
NSData *postData = [NSJSONSerialization dataWithJSONObject:data options:0 error:&error];
[request setHTTPBody:postData];


NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
// write logic after geting response from the server 
}];

[postDataTask resume];

100% 有效

NSString *post = [NSString stringWithFormat:@"username=%@&password=%@",@"Raja",@"12345"];
    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
    NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[post length]];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://localhost/promos/index.php"]];


[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody:postData];

NSURLConnection *theConnection = [NSURLConnection connectionWithRequest:request delegate:self];

if( theConnection ){
    // indicator.hidden = NO;
    mutableData = [[NSMutableData alloc]init];
}

你的 PHP 代码

<?php
    $username = $_POST['username'];
    $password=$_POST['password'];


    echo $username;
?>
