前言
在代码中，我们经常需要进行网络请求数据。这里就有下面几种思路可供选择。
- 直接使用底层，判断网络状态，这种对编程人员要求比较高。对底层不了解的无法完成。
- 采用AFNetworking等第三方框架，使用类AFNetworkReachabilityManager进行判断。
- 在实际项目中很多情况是需要封装网络框架。这里面也有两种思路，一种将网络请求数据和网络监测封装在一起，而我们只需调用该单例，不用关心网络监测，因为内部已经实现了监测。另外一种就是网络数据请求和网络情况监测分别封装，在请求网络数据的时候先进行网络判断，同样也封装成一个单例。
这里我就简单的封装了个网络监测工具，希望大神多多指导。
详细设计
先看一下我的代码结构。
网络监测工具文档组织结构
然后直接看代码。
1. AppDelegate.m
#import "AppDelegate.h"
#import "JJTestVC.h"
#import "JJNetworkReachabilityTool.h"
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[[JJNetworkReachabilityTool shareNetworkReachabilityTool] application:application didFinishLaunchingWithOptions:launchOptions];
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
JJTestVC *testVC = [[JJTestVC alloc] init];
self.window.rootViewController = testVC;
[self.window makeKeyAndVisible];
return YES;
}
- (void)applicationWillResignActive:(UIApplication *)application {
}
- (void)applicationDidEnterBackground:(UIApplication *)application {
}
- (void)applicationWillEnterForeground:(UIApplication *)application {
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
}
- (void)applicationWillTerminate:(UIApplication *)application {
[[JJNetworkReachabilityTool shareNetworkReachabilityTool] applicationWillTerminate:application];
}
@end
2. JJTestVC.m
#import "JJTestVC.h"
#import "JJNetworkReachabilityTool.h"
@interface JJTestVC ()
@end
@implementation JJTestVC
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor greenColor];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[self.view addSubview:button];
[button setTitle:@"网络状况" forState:UIControlStateNormal];
[button setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
button.layer.borderWidth = 2;
button.layer.borderColor = [UIColor blueColor].CGColor;
[button addTarget:self action:@selector(buttonDidClick) forControlEvents:UIControlEventTouchUpInside];
[button sizeToFit];
button.center = self.view.center;
}
#pragma mark - 网络监测
- (void)buttonDidClick
{
switch ([JJNetworkReachabilityTool shareNetworkReachabilityTool].currentStatus){
case JJNetworkReachabilityToolNetStatusNotReachable:
NSLog(@"没有网络");
break;

NSLog(@"蜂窝网络");
break;
