在PC上监测web页面的HTTP请求是一件非常简单的事，我们有大量的软件可以来做，甚至浏览器就自带了有这样功能的开发插件。但是在移动设备上就没那么简单了，没有软件，权限控制……下面将介绍2种监测移动设备HTTP请求的方式。

使用Charles

在连上WIFI的前提下，android和ios设备都可以通过Charles来监测HTTP请求，原理是通过Charles在PC上架设一个代理，手机访问这个代理，Charles记录网络请求。ios设备，在“设置”-“无线局域网络”里可以直接设置代理，而android没有设置代理的功能，需要取得root权限后安装第三方软件来实现。

操作步骤：
下载Charles（http://www.charlesproxy.com/download/），安装完成后打开软件
通过菜单上的“Proxy”-“Proxy Settings…”，进入代理设置见面
“Port”填默认的“8888”即可，勾选“Enable transparent HTTP proxying”，点“OK”确认
设置手机的代理，端口（Port）写Charles中的端口设置，即“8888”，IP填你PC的IP地址
用手机发起任意HTTP请求，Charles会弹出一个提示框，点“Allow”，好了HTTP请求都出现在Charles里了

全选所有请求，并选择右侧的“Chart”选项卡就能看到整个HTTP请求瀑布图了：

Android手机设置代理的方式：
安装“z4root”软件，进入软件后选择第二项，等待一段时间后，自动重启，取得root权限完成
安装“Transparent Proxy”，进入“Proxy Host”设置PC的IP地址，进入“Proxy Port”设置端口号，即“8888”，勾选“Proxy”，设置完成

使用TCPDUMP和Wireshark

Android手机，可以使用TCPDUMP输出网络请求的LOG文件，然后用Wireshark打开该文件，进行统计分析。

操作步骤：
下载TCPDUMP（http://www.strazzere.com/android/tcpdump），放到D根目录盘下
下载安装Wireshark（http://www.wireshark.org/）
root手机，方法如上所述
用usb连上手机
打开命令行工具CMD，依次输入如下命令：
adb push d:\tcpdump /data/local/tcpdump
adb shell chmod 6755 /data/local/tcpdump
adb shell tcpdump -p -vv -s 0 -w /sdcard/capture.pcap -Z root
停止抓包：按Ctrl+c
导出抓包得到的文件到d盘根目录：adb pull /sdcard/capture.pcap d:/
双击capture.pcap文件，wireshark启动

一开始不知如何在iphone里设置代理，网上说的大部分都是设置vpn的并不是代理设置。功夫不负有心人，在换了不同的关键字查找，终于找到设置方法了！其实很简单，步骤如下：
1,连上wifi

2,在 设置=>Wi-Fi=>你连上的网络右边的小箭头 然后往下拉有http代理设置这一栏，选择手动，然后输入你的代理服务器地址或者域名以及端口！

匹配9-15个由字母/数字组成的字符串的正则表达式：

1

3
NSString * regex = @"^[A-Za-z0-9]{9,15}$";
NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regex];
BOOL isMatch = [pred evaluateWithObject:txtfldPhoneNumber.text];

Cocoa用NSPredicate描述查询的方式，原理类似于在数据库中进行查询

用BETWEEN，IN，BEGINWITH，ENDWITH，CONTAINS，LIKE这些谓词来构造NSPredicate，必要的时候使用SELF直接对自己进行匹配
基本的查询

NSPredicate *predicate; 
predicate = [NSPredicate predicateWithFormat: @"name == 'Herbie'"]; 
BOOL match = [predicate evaluateWithObject: car]; 
NSLog (@"%s", (match) ? "YES" : "NO"); 
//在整个cars里面循环比较  
predicate = [NSPredicate predicateWithFormat: @"engine.horsepower > 150"]; 
NSArray *cars = [garage cars]; 
for (Car *car in [garage cars]) {
	if ([predicate evaluateWithObject: car]) { 
		NSLog (@"%@", car.name); 
	} 
}

//含有变量的谓词  
NSPredicate *predicateTemplate = [NSPredicate predicateWithFormat:@"name == $NAME"];

varDict = [NSDictionary dictionaryWithObjectsAndKeys: @"Herbie", @"NAME", nil]; 
predicate = [predicateTemplate predicateWithSubstitutionVariables: varDict]; 
NSLog(@"SNORGLE: %@", predicate); 
match = [predicate evaluateWithObject: car]; 
NSLog (@"%s", (match) ? "YES" : "NO");

注意不能使用$VARIABLE作为路径名，因为它值代表值

很多情况需要从网络上加载图片，然后将图片在imageview中显示出来，但每次都要从网络上请求，会严重影响用户体验，为了不是每次显示都需要从网上下载数据，希望将图片放到本地缓存，因此我们需要一个好的的缓存策略，今天我将我在项目工程中的实际经验分享给大家，我这里主要介绍一下强大的ASIHTTPRequest的缓存策略，以及使用方法：

下面是具体步骤：
一、设置缓存策略
首先在SplitDemoAppDelegate委托代理中，实现如下代码：
在SplitDemoAppDelegate.h文件中，代码如下：

#import <UIKit/UIKit.h>
@class ASIDownloadCache;

@interface SplitDemoAppDelegate : NSObject <UIApplicationDelegate,UITabBarControllerDelegate> {

    UIWindow *_window;

    ASIDownloadCache*_downloadCache;            //下载缓存策略

}

@property (nonatomic, retain) ASIDownloadCache*downloadCache;

@end

在SplitDemoAppDelegate.m文件中，代码如下:

#import "SplitDemoAppDelegate.h"
 
@implementation SplitDemoAppDelegate

@synthesize window=_window;

@synthesize downloadCache = _downloadCache;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions

{

    //初始化ASIDownloadCache缓存对象

    ASIDownloadCache *cache = [[ASIDownloadCache alloc] init];

    self.downloadCache = cache;

    [cache release];

    //路径

    NSArray *paths =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);

    NSString *documentDirectory = [paths objectAtIndex:0];

    //设置缓存存放路径

    [self.downloadCache setStoragePath:[documentDirectorystringByAppendingPathComponent:@"resource"]];

    //设置缓存策略

    [self.downloadCache setDefaultCachePolicy:ASIOnlyLoadIfNotCachedCachePolicy];

    // Override point for customization after application launch.

    [self.window makeKeyAndVisible];

    return YES;

}


- (void)dealloc

{

    [_window release];

    [_downloadCache release];

    [super dealloc];

}
@end

二、创建缓存线程

这一步是创建一个NSOperation类，实现缓存的方法，代码如下：

ResourceContainer.h文件实现

#import <Foundation/Foundation.h>

#import "ASIHTTPRequest.h"

#import "SplitDemoAppDelegate.h"

@interface ResourceContainer : NSOperation {

NSURL*_resourceURL;            //资源请求url

NSObject*_hostObject;             

SEL_resourceDidReceive;      //资源接手响应方法  

SplitDemoAppDelegate*_appDelegate;            //应用委托对象

ASIHTTPRequest*_httpRequest;            

UIImageView*_imageView;              

}

@property (nonatomic, retain) NSURL*resourceURL;

@property (nonatomic, retain) NSObject*hostObject;

@property (nonatomic, assign) SELresourceDidReceive;

@property (nonatomic, assign) SplitDemoAppDelegate   *appDelegate;

@property (nonatomic, retain) ASIHTTPRequest*httpRequest;

@property (nonatomic, retain) UIImageView*imageView;

//http请求回调方法

-(void)didStartHttpRequest:(ASIHTTPRequest *)request;

-(void)didFinishHttpRequest:(ASIHTTPRequest *)request;

-(void)didFailedHttpRequest:(ASIHTTPRequest *)request;

//取消资源请求

-(void)cancelReourceGet;

//资源接收回调方法

-(void)resourceDidReceive:(NSData *)resource;

@end

ResourceContainer.m文件实现：

#import "ResourceContainer.h"
#import "HttpConstant.h"
#import "ASIDownloadCache.h"
@implementation ResourceContainer
@synthesize resourceURL = _resourceURL;
@synthesize hostObject = _hostObject;
@synthesize resourceDidReceive = _resourceDidReceive;
@synthesize appDelegate = _appDelegate;
@synthesize httpRequest = _httpRequest;
@synthesize imageView = _imageView;

-(id)init{

    if(self == [super init]){
        self.appDelegate = (SplitDemoAppDelegate *)[[UIApplication sharedApplication] delegate];
    }
    return self;
}


-(void)main{

    if(self.hostObject == nil)
    return;

    if(self.resourceURL == nil){
        [self resourceDidReceive:nil];
        return;
    }

    ASIHTTPRequest *request = [ASIHTTPRequest     requestWithURL:self.resourceURL]
    self.httpRequest = request;



    [self.httpRequest setDownloadCache:self.appDelegate.downloadCache];
    [self.httpRequest setDelegate:self];
    [self.httpRequest setDidStartSelector:@selector(didStartHttpRequest:)];
    [self.httpRequest setDidFinishSelector:@selector(didFinishHttpRequest:)];
    [self.httpRequest setDidFailSelector:@selector(didFailedHttpRequest:)];

    //发异步请求

    [self.httpRequest startAsynchronous];

}

- (void)dealloc {

    [_resourceURL release];
    [_hostObject release];
    [_httpRequest release];
    [_imageView release];
    [super dealloc];

}

//开始请求

-(void)didStartHttpRequest:(ASIHTTPRequest *)request{

    [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];

}

//请求成功返回处理结果

-(void)didFinishHttpRequest:(ASIHTTPRequest *)request{

    [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];

    if([request responseStatusCode] == 200 || [request responseStatusCode] == 304){

        //判断是否来自缓存

        if([request didUseCachedResponse]){
            NSLog(@"=========资源请求：%@ 来自缓存============",[self.resourceURL absoluteURL]);
        }
        else{
            NSLog(@"=========资源请求：图片不来自缓存============");
        }
        [self resourceDidReceive:[request responseData]];

    }
    else
    {

        [self resourceDidReceive:nil];

    }

}

//失败请求返回处理结果

-(void)didFailedHttpRequest:(ASIHTTPRequest *)request{

    [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];

    [self resourceDidReceive:nil];

}

//取消资源请求

-(void)cancelReourceGet{

    [self.httpRequest cancel];

}

//资源接收处理方法

-(void)resourceDidReceive:(NSData *)resource{

    if([self.hostObject respondsToSelector:self.resourceDidReceive]){

        if(resource != nil && self.imageView != nil){

            self.imageView.image = [UIImage imageWithData:resource];

        }

        [self.hostObject performSelectorOnMainThread:self.resourceDidReceive withObject:self.imageViewwaitUntilDone:NO];

    }

}
@end

到第二步，我们的缓存策略的设置，以及资源请求和接收数据方法已经构建完毕，下面介绍一下如何使用我们上面创建的NSOperation类
三、图片请求（利用上面创建的类）

    NSMutableArray            *_originalIndexArray;        //保存请求图片的号

    NSMutableDictionary     *_originalOperationDic;     //保存图片请求队列

    NSOperationQueue        *_requestImageQueue;    //图片请求队列

}

@property (nonatomic, retain) NSURL                       *imageURL;
@property (nonatomic, retain) NSMutableArray          *originalIndexArray;
@property (nonatomic, retain) NSMutableDictionary   *originalOperationDic;
@property (nonatomic, retain) NSOperationQueue      * requestImageQueue;

//显示图片信息

-(void)displayProductImage;

//根据图片序号显示请求图片资源

-(void)displayImageByIndex:(NSInteger)index ByImageURL:(NSURL *)url;

//处理图片请求返回信息

-(void)imageDidReceive:(UIImageView *)imageView;

@end

 //若数组中已经存在该图片编号，说明图片加载完毕，直接返回

 if ([self.originalIndexArray containsObject:indexForString]) {

      return;

 }

 //创建UIImageView对象

 UIImageView *imageView = [[UIImageView alloc] init];

 imageView.tag = index;

 //创建资源请求对象

 ResourceContainer  *imageOperation = [[ResourceContainer alloc] init];

 imageOperation.resourceURL = url;

 imageOperation.hostObject = self;

 //设置收到图片信息处理理方法

 imageOperation.resourceDidReceive = @selector(imageDidReceive:);

 imageOperation.imageView = imageView;

 [imageView release];

 //将图片请求对象加入图片请求队列中

 [self.requsetImageQueue addOperation:imageOperation];

 [self.originalOperationDic setObject:imageOperation forKey:indexForString];

 [imageOperation release];

}
 
//处理图片请求返回信息

-(void)imageDidReceive:(UIImageView *)imageView
{

    if (imageView == nil||imageView.image == nil) {
        imageView.image = [UIImage imageNamed:@"no-pic-300-250.png"];
    }
    //将图片信息加载到前台，self.openFlowView是我用的coverFlow，coverFlow的使用方法网上很多，自己找吧

    [self.openFlowView setImage:imageView.image forIndex:imageView.tag];

    [self.originalIndexArray addObject:[NSString stringWithFormat:@"%d",imageView.tag]];

    [self.originalOperationDic removeObjectForKey:[NSString stringWithFormat:@"%d",imageView.tag]];
}
 
- (void)dealloc
{
    [_requestImageQueue release];

    [_originalIndexArray release];

    [_originalOperationDic release];

    [_imageURL release];

    [super dealloc];
}
 
@end

经过上述步骤，我们实现了加载网络图片时缓存功能，增强了用户体验效果。

虽然说这样的效率不好，但是既然有这样的方式就有这种方式存在的道理

我记录一下其实现方法：

1
cell.imageViewPic.image = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"personpanel-%@-zfx.jpg",[dic valueForKey:@"person_id"]] relativeToURL:[NSURL URLWithString:@"http://xxxx.xxxx.xxxxx/xxxx/"]]]];

cell.imageViewPic是一个实例化的UIImageview

使用RegexKitLite正则表达式需要以下工作：
1.RegexKitLite官方网址（内含使用教程）：http://regexkit.sourceforge.net/RegexKitLite
2.下载地址：http://downloads.sourceforge.net/regexkit/RegexKitLite-4.0.tar.bz2
3.将RegexKitLite.h和RegexKitLite.m引入到工程中。
4.引入”libicucore.dylib”框架
5.需要在处理的类中导入”RegexKitLite.h”

言归正传，用正则表达式提取匹配的内容（此例子中讲述匹配字符串中的手机号码）：

1
2
3
4
5
NSString *searchString = @"15200000000,1234,12012345678,13400000000"; // 要提取的字符串
NSString *regexString  = @"\\b(13|15|18)([0-9]{9})\\b";  // 手机号码的正则表达式（由于15和18号段的不太熟悉，索性就干脆都算上了，你懂的。）
NSArray  *matchArray  = [searchString componentsMatchedByRegex:regexString];  // 匹配结果以数组形式返回
NSLog(@"%@",matchArray); // 进行输出
NSLog(@"%@",matchArray);

输出结果如下：

1

2011-08-23 14:39:23.356 ZQRegex[6726:207] (
    15200000000,
    13400000000

通过setTitle和titleEdgeInsets，setImage和imageEdgeInsets，能够实现title和image位置的变化

具体的代码我以实现title的位置变化为例子：

UIButton *addButton = [UIButton buttonWithType:UIButtonTypeCustom];
addButton.layer.borderColor = [[UIColor whiteColor] CGColor];
addButton.layer.borderWidth = 2.0;
addButton.layer.cornerRadius = 10.0;
addButton.titleLabel.font = [UIFont systemFontOfSize:54.0];
addButton.titleLabel.textAlignment = NSTextAlignmentCenter;
[addButton sizeToFit];
[addButton setTitleEdgeInsets:UIEdgeInsetsMake(-10.0, 0.0, 0.0, 0.0)];
[addButton setFrame:CGRectMake(0.0, 5.0, 60.0, 60.0)];
[addButton setTitle:@"+" forState:UIControlStateNormal];
[addButton addTarget:self
              action:@selector(addAction:)
    forControlEvents:UIControlEventTouchUpInside];

看了几个实例，最终解决了这个问题，之间为什么老是有问题没有解决呢，原因我觉得是跟ARC有关，因为我的应用是使用ARC的然后将下载回来的代码进行了调整，将release的代码段去掉了。结果有了一些问题，也不是很了解具体是哪里。目前问题解决了，里面使用了关于ARC机制和非ARC机制共存的办法,详细的内容可以参考我的这篇文章iOS 开发，工程中混合使用 ARC 和非ARC。

代码段贴一下好了：

问题是这样的：

在项目开发过程中我们通常会用到第三方提供的源代码，麻烦的是有些开源项目用的是 ARC，有的用的是非 ARC。
我在使用 SVProgressHUD 做等待视图时遇到问题，最终发现该项目使用的是 ARC 模式，而我的工程使用的是非 ARC 模式。

解决方法是这样的：

Xcode 项目中我们可以使用 ARC 和非 ARC 的混合模式。
如果你的项目使用的非 ARC 模式，则为 ARC 模式的代码文件加入 -fobjc-arc 标签。
如果你的项目使用的是 ARC 模式，则为非 ARC 模式的代码文件加入 -fno-objc-arc 标签。
添加标签的方法：
1，打开：你的target -> Build Phases -> Compile Sources.
2，双击对应的 *.m 文件
3，在弹出窗口中输入上面提到的标签 -fobjc-arc / -fno-objc-arc
4，点击 done 保存
