介紹完了服務(wù)器，這篇我們就要介紹重點(diǎn)了，寫我們自己的IOS客戶端程序

先看一下我們完成的效果圖

首先下載xmppframework這個(gè)框架,下載

點(diǎn)Zip下載

接下來(lái)，用Xcode新建一個(gè)工程

將以下這些文件拖入新建工程中

加入framework

并設(shè)置

到這里我們就全部設(shè)好了，跑一下試試，看有沒(méi)有錯(cuò)呢

如果沒(méi)有錯(cuò)的話，我們的xmppframework就加入成功了。

我們?cè)O(shè)置我們的頁(yè)面如下圖：

我們的KKViewController.h

[java] view plain copy

# import <UIKit/UIKit.h>
@interface KKViewController : UIViewController<UITableViewDelegate, UITableViewDataSource>
@PRoperty (strong, nonatomic) IBOutlet UITableView *tView;
- (IBAction)Account:(id)sender;
@end

KKViewController.m

[java] view plain copy

# import "KKViewController.h"
@interface KKViewController (){
//在線用戶
NSMutableArray *onlineUsers;
}
@end
@implementation KKViewController
@synthesize tView;
- (void )viewDidLoad
{
[super viewDidLoad];
self.tView.delegate = self;
self.tView.dataSource = self;
onlineUsers = [NSMutableArray array];
// Do any additional setup after loading the view, typically from a nib.
}
- (void )viewDidUnload
{
[self setTView:nil];
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
- (IBAction)Account:(id)sender {
}
#pragma mark UITableViewDataSource
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return [onlineUsers count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *identifier = @ "userCell" ;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
}
return cell;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1 ;
}
#pragma mark UITableViewDelegate
-(void )tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
}
@end

這里的代碼相信大家學(xué)過(guò)UITableView的話應(yīng)該很熟悉了，如果不知道的話，就查一下UITableView的簡(jiǎn)單應(yīng)用學(xué)習(xí)一下吧

接下來(lái)是登錄的頁(yè)面

KKLoginController.m

[java] view plain copy

- (IBAction)LoginButton:(id)sender {
if ([self validateWithUser:userTextField.text andPass:passTextField.text andServer:serverTextField.text]) {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:self.userTextField.text forKey:USERID];
[defaults setObject:self.passTextField.text forKey:PASS];
[defaults setObject:self.serverTextField.text forKey:SERVER];
//保存
[defaults synchronize];
[self dismissModalViewControllerAnimated:YES];
}else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@ "請(qǐng)輸入用戶名，密碼和服務(wù)器" delegate:nil cancelButtonTitle:@ "確定" otherButtonTitles:nil, nil];
[alert show];
}
}
- (IBAction)closeButton:(id)sender {
[self dismissModalViewControllerAnimated:YES];
}
-(BOOL)validateWithUser:(NSString *)userText andPass:(NSString *)passText andServer:(NSString *)serverText{
if (userText.length > 0 && passText.length > 0 && serverText.length > 0 ) {
return YES;
}
return NO;
}

下面是聊天的頁(yè)面

這里著重的還是UITableView

KKChatController.m

[java] view plain copy

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1 ;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return [messages count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *identifier = @ "msgCell" ;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:identifier];
}
NSMutableDictionary *dict = [messages objectAtIndex:indexPath.row];
cell.textLabel.text = [dict objectForKey:@"msg" ];
cell.detailTextLabel.text = [dict objectForKey:@"sender" ];
cell.accessoryType = UITableViewCellAccessoryNone;
return cell;
}
