从网上各位iOS们收集并总结：
各方法使用：
- init 中初始化一些UI组件，比如UIButton,UILabel等
- loadView 中
- createFields 接受参数,初始化变量
- createViews 创建视图
- createEvents 绑定事件,如按钮的点击,NotificationCenter,kvo等
- viewDidLoad
- loadData 加载数据,调用一些api
- dealloc（现在dealloc中做的事我放在了viewDidDisapper中）
- destroyEvents 取消事件的绑定
- destroyViews 释放,销毁视图
- destroyFields 释放,销毁引用的变量
- didReceiveMemoryWarning
- cleanData 释放一些可以释放的数据
- 额外
- enterForeground 进入前台时调用
- enterBackground 进入后台时调用
规范文件内部组织结构：
统一UIViewController风格，首先是头文件：
@interfaceUIViewController(base)
#pragma mark- model
// 定义model
#pragma mark- view
// 定义view
#pragma mark- api
// 定义api @end
然后是实现文件：
#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];
}
