项目中经常要用到第三方的SDK每次都要在AppDelegate中注册APPKEY 接受回调等 这样就使本来很简洁的AppDelegate中的代码越来越多 那么问题来了 怎样把这些第三方的代码提到其他的地方使用啊？
runtime是一个好东西 给AppDelegate写个分类（AppDelegate+TimingChat） 在分类中替换原来的方法。
本人项目中是这样写的 如下：
#import "AppDelegate+TimingChat.h"
#import <objc/runtime.h>
#import "TimingCustomAttachmentDecoder.h"
#import "TimingCellLayoutConfig.h"
#define APPKEY @""
#define APNSCERNAME @""
//这个暂时不需要
#define PKCERNAME @""
@implementation AppDelegate (TimingChat)
+(void)load {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
Class class = [self class];
swizzleMethod(class, @selector(application:didFinishLaunchingWithOptions:), @selector(aop_application:didFinishLaunchingWithOptions:));
swizzleMethod(class, @selector(applicationDidEnterBackground:), @selector(aop_applicationDidEnterBackground:));
swizzleMethod(class, @selector(applicationWillEnterForeground:), @selector(aop_applicationWillEnterForeground:));
swizzleMethod(class, @selector(applicationDidBecomeActive:), @selector(aop_applicationDidBecomeActive:));
swizzleMethod(class, @selector(applicationWillTerminate:), @selector(aop_applicationWillTerminate:));
swizzleMethod(class, @selector(application:didRegisterForRemoteNotificationsWithDeviceToken:), @selector(aop_application:didRegisterForRemoteNotificationsWithDeviceToken:));
swizzleMethod(class, @selector(handleNotification:), @selector(aop_handleNotification:));
});
}
static inline void swizzleMethod(Class class, SEL originalSelector, SEL swizzledSelector) {
Method originalMethod = class_getInstanceMethod(class, originalSelector);
Method swizzledMethod = class_getInstanceMethod(class, swizzledSelector);
BOOL didAddMethod = class_addMethod(class, originalSelector, method_getImplementation(swizzledMethod), method_getTypeEncoding(swizzledMethod));
if (didAddMethod) {
class_replaceMethod(class, swizzledSelector, method_getImplementation(originalMethod), method_getTypeEncoding(originalMethod));
} else {
method_exchangeImplementations(originalMethod, swizzledMethod);
}
}

runtime的方法交换是个好东西（也是魔鬼）
细心的读者应该注意到了下面的方法中调用了 [self aop_applicationDidEnterBackground:application]; 会产生死循环调用的问题吗？其实没有死循环 他会调用原来的方法applicationDidEnterBackground: 在调用aop_applicationDidEnterBackground:替换的方法 这样就不会影响原来的applicationDidEnterBackground:方法里面的调用内容
-(void)aop_applicationDidEnterBackground:(UIApplication *)application{
[self aop_applicationDidEnterBackground:application];
NSLog(@"分类 applicationDidEnterBackground");
}
这样就可以给AppDelegate瘦身了 其他的第三方可以这样写
