OK，小姐姐又來搞事情了，最近正在重構(gòu)項目，今天就來分享一下項目中baseViewController的寫法吧。當(dāng)然可以視具體業(yè)務(wù)邏輯進(jìn)行相應(yīng)的增刪改好吧。
直接上代碼吧，直觀點咯。

#import <UIKit/UIKit.h>

@interface HQBaseViewController : UIViewController<NavViewDelegate>
@property (nonatomic,strong) NavView * navView;

@property (nonatomic,strong) UITableView *tableView;
@property (nonatomic,strong) NSMutableArray *dataArray;
@property (nonatomic,assign) NSInteger currentPage;
@property (nonatomic,assign) NSInteger preQueryPage;

// 加載數(shù)據(jù)
-(void)loadData;

//上下拉刷新之后處理
-(void)handleRefreshWithCurrentPage:(NSInteger)currentPage totalPage:(NSInteger)totalPage ;

//添加上下拉刷新
-(void)addTableViewHeaderRefresh:(BOOL)headerRefresh footerRefresh:(BOOL)footerRefresh;

- (void)initNavViewWithRightStr:(NSString *) rightStr andNavTitle:(NSString *) navTitle andType:(NavViewType) type andNavBackgroundColor:(UIColor *)bgColor andTitleColor:(UIColor *)titleColor;

@end

首先主要是一個全局的導(dǎo)航欄咯---NavView (自己封裝的，基本適應(yīng)90%項目需求) 如果導(dǎo)航欄過于奇葩請老老實實再寫一個吧，如果很多地方也是一樣的奇葩樣式建議封裝成組件。
接下來就是一個tableview，就小姐姐的項目，90%的頁面帶tableview，所以把他寫在基類里也挺方便的，當(dāng)然如果沒有tableview也無所謂，老老實實控制器該咋寫咋寫，還有就是把下拉刷新和上拉加載寫在基類里，那么就不需要每個有類似功能的頁面都寫一遍代碼，雖然是copy也是挺煩的不是么？有沒有和我一樣copy也不愿意的小哥哥！??
接下來看看.m文件把

#import "HQBaseViewController.h"

@interface HQBaseViewController ()
<
UITableViewDelegate,
UITableViewDataSource
>
@end
@implementation HQBaseViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.edgesForExtendedLayout = UIRectEdgeNone;
    self.view.backgroundColor = [UIColor whiteColor];
    self.currentPage = 1;
    if (!_dataArray) {
        _dataArray = [NSMutableArray array];
    }
}

-(void)dealloc{
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    [[SDImageCache sharedImageCache] clearMemory];//清內(nèi)存
    [[SDImageCache sharedImageCache] clearDisk];//清內(nèi)存
    [[SDImageCache sharedImageCache] cleanDisk];//清內(nèi)存
    // 1.取消正在下載的操作
    [[SDWebImageManager sharedManager] cancelAll];
    // 2.清除內(nèi)存緩存
    [[SDWebImageManager sharedManager].imageCache clearMemory];
}
-(void)addTableViewHeaderRefresh:(BOOL)headerRefresh footerRefresh:(BOOL)footerRefresh{
    if (headerRefresh) {
        self.tableView.mj_header = [MJRefreshNormalHeader headerWithRefreshingTarget:self refreshingAction: @selector(loadNewData)];
    }
    if (footerRefresh) {
        self.tableView.mj_footer=[MJRefreshBackNormalFooter footerWithRefreshingTarget:self refreshingAction:@selector(loadMoreData)];
    }
}

-(void)loadNewData{
    self.currentPage=1;
    self.preQueryPage = 0;
    [self.tableView.mj_footer resetNoMoreData];
    [self loadData];
}

-(void)loadMoreData{
    self.currentPage++;
    [self loadData];
}

-(void)loadData{

}

-(void)handleRefreshWithCurrentPage:(NSInteger)currentPage totalPage:(NSInteger)totalPage {
    if (totalPage>0) {
        [self.tableView reloadData];
    }
    if (currentPage>=totalPage) {
        [self.tableView.mj_footer endRefreshingWithNoMoreData];
    }else{
        if (self.preQueryPage != currentPage && currentPage > 0 && currentPage < totalPage && self.tableView.contentSize.height < CGRectGetHeight(self.tableView.frame)) {
            [self loadMoreData];
        }else{
            [self.tableView.mj_footer endRefreshing];
        }
    }
    self.preQueryPage = currentPage;
    
    if ([self.tableView.mj_header isRefreshing]) {
        [self.tableView.mj_header endRefreshing];
    }
}
#pragma mark - 導(dǎo)航欄處理
- (void)initNavViewWithRightStr:(NSString *) rightStr andNavTitle:(NSString *) navTitle andType:(NavViewType) type andNavBackgroundColor:(UIColor *)bgColor andTitleColor:(UIColor *)titleColor
{
    self.navView = [NavView navViewWithBackIcon:nil andRightStr:rightStr andNavTitle:navTitle andType:type andNavBackgroundColor:bgColor andTitleColor:titleColor];
    self.navView.delegate=self;
    [self.view addSubview:self.navView];
}

/**

 */
- (void)navViewClickLeftBtn:(NavView *)navView
{
    [self.navigationController popViewControllerAnimated:YES];
}


/**

- (void)navViewClickRightBtn:(NavView *)navView
{
    [self.navigationController popViewControllerAnimated:YES];
}

@end

內(nèi)容應(yīng)該都能看懂哦，我挺相信你們的。那看看如何在頁面中使用吧。
首先，創(chuàng)建的時候當(dāng)然是要繼承基類啦，要不你寫基類干啥對吧??

#import <UIKit/UIKit.h>

@interface HQMyOrderMainVC : YVBaseViewController

@end

添加導(dǎo)航條只需要

    // 添加導(dǎo)航條
    [self initNavViewWithRightStr:nil andNavTitle:@"我的訂單" andType: NavViewTypeLeftIcon andNavBackgroundColor:nil andTitleColor:nil];

視業(yè)務(wù)需求決定是否需要上拉下拉功能

    // 添加下拉刷新和上拉加載
    [self addTableViewHeaderRefresh:YES footerRefresh:YES];

重寫一下load()方法

// 下拉刷新
- (void)loadData {
    HQOrderBaseService *orderBaseService = [HQOrderBaseService defaultOrderBaseService];
    [orderBaseService getOrderList:[NSString stringWithFormat:@"%ld",(long)page] OrderType:status Success:^(NSDictionary *params) {
        [self.contentTbv.mj_header endRefreshing];
        [self.contentTbv.mj_footer endRefreshing];
        if (page==1) {
            if (self.orderCountArr.count!=0) {
                [self.orderCountArr removeAllObjects];
            }
        }
        if (self.orderCountArr.count!=0) {
            totalPage=[params[@"data"][@"pagination"][@"totalPage"] integerValue];
            [self handleRefreshWithCurrentPage:self.currentPage totalPage:totalPage];
        }
    } Error:^(NSString *errorMsg) {
        [MBProgressHUD Message:errorMsg For:self.view yOffset:0];
    } Fail:^(NSError *error) {
        [MBProgressHUD Message:@"請求數(shù)據(jù)失??！" For:self.view yOffset:0];
    }];
}   

對了如果一進(jìn)頁面沒有數(shù)據(jù)記得調(diào)用一下
[self.tableView.mj_header beginRefreshing];
其它就不說了，有什么想法再來和小姐姐交流。吃飯去了，餓死。
