从网上各位iOS们收集并总结：
统一UIViewController风格，首先是头文件：
1 @interfaceUIViewController(base) 2 #pragma mark- model 3 // 定义model 4 #pragma mark- view 5 // 定义view 6 #pragma mark- api 7 // 定义api 8 9 @end
#pragma mark - api // 对外的接口 #pragma mark - rewrite // 额外的重写的父类的方法 #pragma mark -private //... #pragma mark -响应 model 的地方 //... #pragma mark 1 notification //... #pragma mark 2 KVO //... #pragma mark -响应 view 的地方 //... #pragma mark 1 target-action //... #pragma mark 2delegate dataSource protocol //... #pragma mark -其他 //...
统一命名：
实现可以用runtime，也可以用基类，个人推荐是用基类，但是下面的代码是runtime的
@implementationUIViewController(base) +(void)load { XY_swizzleInstanceMethod([UIViewControllerclass],@selector(loadView),@selector(xy__loadView)); XY_swizzleInstanceMethod([UIViewControllerclass],@selector(viewDidLoad),@selector(xy__viewDidLoad)); XY_swizzleInstanceMethod([UIViewControllerclass],NSSelectorFromString(@"dealloc"),@selector(xy__dealloc)); XY_swizzleInstanceMethod([UIViewControllerclass],@selector(didReceiveMemoryWarning),@selector(xy__didReceiveMemoryWarning)); } -(void) xy__loadView { [self xy__loadView]; if([self respondsToSelector:@selector(createFields)]) [self performSelector:@selector(createFields)]; if([self respondsToSelector:@selector(createViews)]) [self performSelector:@selector(createViews)]; if([self respondsToSelector:@selector(enterBackground)]){ [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(enterBackground) name:UIApplicationDidEnterBackgroundNotification object:nil]; } if([self respondsToSelector:@selector(enterForeground)]){ [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(enterForeground) name:UIApplicationWillEnterForegroundNotification object:nil]; } if([self respondsToSelector:@selector(createEvents)]) [self performSelector:@selector(createEvents)]; } -(void)xy__dealloc { [[NSNotificationCenter defaultCenter] removeObserver:self]; if([self respondsToSelector:@selector(destroyEvents)]) [self performSelector:@selector(destroyEvents)]; if([self respondsToSelector:@selector(destroyViews)]) [self performSelector:@selector(destroyViews)]; if([self respondsToSelector:@selector(destroyFields)]) [self performSelector:@selector(destroyFields)]; [self xy__dealloc]; } -(void)xy__viewDidLoad { if([self respondsToSelector:@selector(loadData)]) [self performSelector:@selector(loadData)]; [self xy__viewDidLoad]; } -(void)xy__didReceiveMemoryWarning { if([self isViewLoaded]&&[self.view window]== nil){ if([self respondsToSelector:@selector(cleanData)]) [self performSelector:@selector(cleanData)]; } [self xy__didReceiveMemoryWarning]; } @end
