使用cocoapod安装完pod之后，要导入头文件，必须先设置头文件路径。

在项目的Target的里设置一下：

Search Paths/User Header Search Paths

输入${SRCROOT}  后面选上recursive。

SBJson

http://cocoadocs.org/docsets/SBJson/3.2/

此网址说明了JSon类型与Objective-c对应关系：http://cocoadocs.org/docsets/SBJson/4.0.0/Classes/SBJson4Parser.html

null -> NSNull

string -> NSString

array -> NSMutableArray

object -> NSMutableDictionary

true -> NSNumber’s -numberWithBool:YES

false -> NSNumber’s -numberWithBool:NO

number -> NSNumber

使用：

//讲字符串转为Json对象（包括NSMutableDictionary,NSMutableArray）

SBJsonParser *parser = [[SBJsonParser alloc] init];

NSString *jsonString = @"{\"foo\":\"bar\"}";

NSMutableDictionary *dict = [parser objectWithString:jsonString];

//讲json对象装换为json字符串

SBJsonWriter *writer = [[SBJsonWriter alloc] init];

NSString *str = [writer stringWithObject:array];

Reachability （用来判断网络连接是否正常)

判断网络是否连接

/***
* 此函数用来判断是否网络连接服务器正常
* 需要导入Reachability类
*/
+ (BOOL)isExistenceNetwork
{
    BOOL isExistenceNetwork;
    Reachability *reachability = [Reachability reachabilityWithHostName:@""];  // 测试服务器状态
   
     switch([reachability currentReachabilityStatus]) {
            case NotReachable:
                  isExistenceNetwork = FALSE;
                  break;
             case ReachableViaWWAN:
                   isExistenceNetwork = TRUE;
                   break;
              case ReachableViaWiFi:
                    isExistenceNetwork = TRUE;
                    break;
     }
     return  isExistenceNetwork;
}

实时通知网络状况

/*
* 在应用委托的方法didFinishLaunchingWithOptions中添加
*/

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reachabilityChanged:) name:kReachabilityChangedNotification object:nil];
reachability = [[Reachability reachabilityWithHostName:@"www.baidu.com"] retain];
[reachability startNotifier];
........
return YES;

/**
*此函数通过判断联网方式，通知给用户
*/
- (void)reachabilityChanged:(NSNotification *)notification
{
      Reachability *curReachability = [notification object];
      NSParameterAssert([curReachability isKindOfClass:[Reachability class]]);
      NetworkStatus curStatus = [curReachability currentReachabilityStatus];
      if(curStatus == NotReachable) {
          [DOIN_Util logFax:@"连接失败"];
      }
}
