直接上代碼：

示例：（在storyboard中拖兩個控件textField、一個UIButton，連線（userNameText、passWord、login））

@interface ViewController()

@PRoperty(nonatomic,weak)IBOutlet UITextField *userNameText;

@property(nonatomic,weak)IBOutlet UITextField *passWord;

@end

-(IBAction)login

{

　　[self postLoginWithUserName:self.userNameText.text password:self.passWord.text];

}

post登陸

-（void）postLoginWithUserName:(NSString *)userName password:(NSString *)password
{

　　//1.url

　　NSURL *url = [NSURL URLWithString:@"http://本機ip/login.php"];

　　//2.request

　　NSMutableNSURLRequest *request = [NSMutableNSURLRequest requestWithURL:url];

　　//對于post請求的數據題要和request一起提交

　　request.HTTPMethod = @"POST";

　　//準備數據題

　　NSString *bodyString = [NSString *stringWithFormat:@"username=%@&password=%@",username,password];

　　//設置二進制數據

　　request.HTTPBody = [bodyString dataUsingEncoding:NSUTF8StringEncoding];

　　//3.發送網絡連接，獲取二進制數據

　　[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLReponse *response,NSData *data,NSError *connectionError)];　

　NSString *result = [NSString alloc]initWithData:data encoding:NSUTF8Encoding];

}

get登陸

-（void）getLoginWithUserName:(NSString *)userName password:(NSString *)password

{

　　//1.url

　　NSString *urlString = [NSString stringWithFormat:@"http://本機IP地址/login.php?username = %@&password = %@",userName,password];

　　//百分號轉義

　　urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

　　NSURL *url = [NSURL URLWithString:urlString];

　　//2.request

　　NSURLRequest *request = [NSURLRequest requestWithURL:url];

　　//3.發送網絡連接，獲取二進制數據

　　[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLReponse *response,NSData *data,NSError *connectionError)];

　　NSString *result = [NSString alloc]initWithData:data encoding:NSUTF8Encoding];

}

小結：

get：

http://本機IP地址/login.php?username = %@&password = %@

http://ip地址/登陸的腳本文件？（后面有參數）參數變量名 = 參數數值&(繼續接參數)變量名 = 數值

post

http://ip地址/登陸的腳本

2.request

get：什么都不需要處理，因為參數已經在URL中指定了

post：指定訪問方法

　　HTTPMethod = @"post";
