Snip20160717_1.png

代码结构我比较喜欢按照业务来区分,大概就是这样子了

新版本特性 思路和实现都比较简单,需要注意的一点是将判断是否有新版本的逻辑提取出来,直接上代码

AppDelegate

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

  self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];

  self.window.rootViewController = [GPGuideTool chooseRootViewController]; [self configApper]; [self.window makeKeyAndVisible]; return YES; } 判断逻辑 // 加载哪个控制器

• (UIViewController *)chooseRootViewController { UIViewController *rootVc = nil;

  NSDictionary *dict = [NSBundle mainBundle].infoDictionary;

  // 获取最新的版本号 NSString *curVersion = dict[@"CFBundleShortVersionString"];

  // 获取上一次的版本号 NSString *lastVersion = [GPUserDefaults objectForKey:GPVersionKey];

  // 之前的最新的版本号 lastVersion if ([curVersion isEqualToString:lastVersion]) { // 版本号相等 rootVc = [[GPAdViewController alloc]init]; }else{ // 有最新的版本号 // 保存到偏好设置 [[NSUserDefaults standardUserDefaults] setObject:curVersion forKey:GPVersionKey]; rootVc = [[GPNewFeatureController alloc]init]; } return rootVc; } 新特性界面实现

• (instancetype)init { // 流水布局 UICollectionViewFlowLayout *layout = [[UICollectionViewFlowLayout alloc] init];

  // 设置cell的尺寸 layout.itemSize = [UIScreen mainScreen].bounds.size;

  // 设置每一行的间距 layout.minimumLineSpacing = 0;

  // 设置每个cell的间距 layout.minimumInteritemSpacing = 0;

  // 设置滚动方向 layout.scrollDirection = UICollectionViewScrollDirectionHorizontal;

  return [self initWithCollectionViewLayout:layout]; }

• (void)viewDidLoad { [super viewDidLoad];

  [self setUpCollectionView];

}

// 初始化CollectionView

• (void)setUpCollectionView { // 注册cell [self.collectionView registerNib:[UINib nibWithNibName:NSStringFromClass([GPNewFeatureCell class]) bundle:nil] forCellWithReuseIdentifier:reuseIdentifier]; // 取消弹簧效果 self.collectionView.bounces = NO;

  // 取消显示指示器 self.collectionView.showsHorizontalScrollIndicator = NO;

  // 开启分页模式 self.collectionView.pagingEnabled = YES;

}

#pragma mark

• (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section { return 5; }

• (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {

  GPNewFeatureCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:reuseIdentifier forIndexPath:indexPath];

  NSString *imageName = [NSString stringWithFormat:@"newfeature_0%ld_736",indexPath.item + 1]; cell.image = [UIImage imageNamed:imageName];

  return cell; }

#pragma mark

• (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.row == 4) {

    // 切换窗口的根控制器进行跳转
  
    [UIApplication sharedApplication].keyWindow.rootViewController = [[GPAdViewController alloc]init];
  
    CATransition *anim = [CATransition animation];
    anim.type = @"rippleEffect";
    anim.duration = 1;
    [[UIApplication sharedApplication].keyWindow.layer addAnimation:anim forKey:nil];
  

  } } 请求数据 方式一 直接在 AFN上面简单包装一下

+(void)get:(NSString *)url params:(NSDictionary *)params success:(void (^)(id responseObj))success failure:(void (^)(NSError *))failure { AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

[manager GET:url parameters:params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    if (success) {
        success(responseObject);
    }
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    if (failure) {
        failure(error);
    }
}];

}

+(void)post:(NSString *)url params:(NSDictionary *)params success:(void (^)(id responseObj))success failure:(void (^)(NSError *))failure { AFHTTPSessionManager *mgr = [AFHTTPSessionManager manager]; [mgr POST:url parameters:params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { if (success) { success(responseObject); } } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { if (failure) { failure(error); } }]; } 方式二 在上面的基础上再次进行封装

• (void)getWithUrl:(NSString *)url param:(id)param resultClass:(Class)resultClass success:(void (^)(id))success failure:(void (^)(NSError *))failure { NSDictionary *params = [param mj_keyValues]; [GPHttpTool get:url params:params success:^(id responseObj) { if (success) { id result = [resultClass mj_objectWithKeyValues:responseObj[@"data"]]; success(result); } } failure:^(NSError *error) { if (failure) { failure(error); } }]; }

• (void)getMoreWithUrl:(NSString *)url param:(id)param resultClass:(Class)resultClass success:(void (^)(id))success failure:(void (^)(NSError *))failure { NSDictionary *params = [param mj_keyValues]; [GPHttpTool get:url params:params success:^(id responseObj) { if (success) { id result = [resultClass mj_objectArrayWithKeyValuesArray:responseObj[@"data"]]; success(result); } } failure:^(NSError *error) { if (failure) { failure(error); } }]; }

• (void)postWithUrl:(NSString *)url param:(id)param resultClass:(Class)resultClass success:(void (^)(id))success failure:(void (^)(NSError *))failure { NSDictionary *params = [param mj_keyValues];

  [GPHttpTool post:url params:params success:^(id responseObj) { if (success) { id result = [resultClass mj_objectWithKeyValues:responseObj]; success(result); } } failure:^(NSError *error) { if (failure) { failure(error); } }]; } 首页

Snip20160718_2.png

首页的整体布局是用 UICollection View 实现的, 这里只贴一下关键代码,具体代码可以下载源代码查看

首页可滚动标题栏在多个地方涉及到,所以可以自己进行简单封装,这里我简单封装一下,在开源项目中此处我用到了一个优秀的三方:

#pragma mark - 懒加载

• (NSMutableArray *)btnArray { if (!_btnArray) {

    _btnArray = [[NSMutableArray alloc] init];
  

  } return _btnArray; }

• (instancetype)initWithChildControllerS:(NSArray *)titleArray { if (self = [super init]) { self.titleArray = titleArray; [self layout]; } return self;

}

• (void)layout { UIButton *lastBtn = nil; for (int i = 0; i < self.titleArray.count; i ++) { UIButton *btn = [[UIButton alloc]init]; [btn setTitle:self.titleArray[i] forState:UIControlStateNormal]; [btn setTitleColor:[UIColor colorWithWhite:1 alpha:0.5] forState:UIControlStateNormal]; [btn setTitleColor:[UIColor whiteColor] forState:UIControlStateSelected]; btn.userInteractionEnabled = NO; [self.btnArray addObject:btn];

    [self addSubview:btn];
    if (lastBtn) {
        btn.sd_layout
        .leftSpaceToView(lastBtn,40)
        .topSpaceToView(lastBtn,0)
        .bottomSpaceToView(lastBtn,0)
        .widthIs(40);
    }else{
        btn.sd_layout
        .leftSpaceToView(self,0)
        .topSpaceToView(self,0)
        .bottomSpaceToView(self,0)
        .widthIs(40);
    }
    lastBtn = btn;
  

  } [self setupAutoWidthWithRightView:lastBtn rightMargin:0]; } // 改变按钮状态 -(void)changeSelectBtn:(UIButton *)btn { self.previousBtn = self.currentBtn; self.currentBtn = btn; self.previousBtn.selected = NO; self.currentBtn.selected = YES; } // 更新按钮状态 -(void)updateSelecterToolsIndex:(NSInteger )index { UIButton *selectBtn = self.btnArray[index]; [self changeSelectBtn:selectBtn]; } 可滚动视图

• (instancetype)initWithChildControllerS:(NSArray *)vcArray selectBlock:(selecBlock)selecB { if (self = [super init]) { self.selecB = selecB; self.backgroundColor = [UIColor whiteColor]; self.pagingEnabled = YES; self.showsVerticalScrollIndicator = NO; self.showsHorizontalScrollIndicator = NO; self.delegate = self; self.childVcArray = vcArray; [self layout]; } return self; }

• (void)layout { UIView *lastView = nil; for (UIViewController viewVc in self.childVcArray) { [self addSubview:viewVc.view]; if (lastView) { viewVc.view.sd_layout .widthIs(SCREEN_WIDTH) .heightIs(SCREEN_HEIGHT) .leftSpaceToView(lastView,0); }else{ viewVc.view.sd_layout .widthIs(SCREEN_WIDTH) .heightIs(SCREEN_HEIGHT) .leftSpaceToView(self,0); } lastView = viewVc.view; } [self setupAutoContentSizeWithRightView:lastView rightMargin:0]; } -(void)updateVCViewFromIndex:(NSInteger )index { [self setContentOffset:CGPointMake(indexSCREEN_WIDTH, 0) animated:YES]; }

-(void)scrollViewDidScroll:(UIScrollView *)scrollView { int page = (scrollView.contentOffset.x + SCREEN_WIDTH / 2) / SCREEN_WIDTH; self.selecB(page); } 轮播图 无限滚动的简单思路就是,当滚动到最右边或最左边的时候,交换图片,具体贴代码

• (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib.

  CGFloat w = self.view.frame.size.width; CGFloat h = self.view.frame.size.height;

  // 初始化scrollView _scrollView.pagingEnabled = YES; _scrollView.contentSize = CGSizeMake(w * 3, 0); _scrollView.contentOffset = CGPointMake(w, 0); _scrollView.showsHorizontalScrollIndicator = NO; _scrollView.delegate = self;

  // 创建可见的imageView UIImageView *visibleView = [[UIImageView alloc] init]; _visibleView = visibleView; _visibleView.image = [UIImage imageNamed:@"00"]; _visibleView.frame = CGRectMake(w, 0, w, h); _visibleView.tag = 0; [_scrollView addSubview:_visibleView];

  // 创建重复利用的imageView UIImageView *reuseView = [[UIImageView alloc] init]; _reuseView = reuseView; _reuseView.frame = self.view.bounds; [_scrollView addSubview:_reuseView]; }

• (void)scrollViewDidScroll:(UIScrollView *)scrollView { // 获取偏移量 CGFloat offsetX = scrollView.contentOffset.x; CGFloat w = scrollView.frame.size.width;

  // 1.设置 循环利用view 的位置 CGRect f = _reuseView.frame; NSInteger index = 0;

  if (offsetX > _visibleView.frame.origin.x) { // 显示在最右边

    f.origin.x = scrollView.contentSize.width - w;
  
    index = _visibleView.tag + 1;
    if (index >= kCount) index = 0;
  

  } else { // 显示在最左边 f.origin.x = 0;

    index = _visibleView.tag - 1;
    if (index < 0) index = kCount - 1;
  

  }

  // 设置重复利用的视图 _reuseView.frame = f; _reuseView.tag = index; NSString *icon = [NSString stringWithFormat:@"0%ld", index]; _reuseView.image = [UIImage imageNamed:icon];

  // 2.滚动到 最左 或者 最右 的图片 if (offsetX <= 0 || offsetX >= w * 2) { // 2.1.交换 中间的 和 循环利用的指针 UIImageView *temp = _visibleView; _visibleView = _reuseView; _reuseView = temp;

    // 2.2.交换显示位置
    _visibleView.frame = _reuseView.frame;
  
    // 2.3 初始化scrollView的偏移量
    scrollView.contentOffset = CGPointMake(w, 0);
  

  }

} 滑动动画

• (void)collectionView:(UICollectionView *)collectionView willDisplayCell:(UICollectionViewCell *)cell forItemAtIndexPath:(NSIndexPath *)indexPath { CATransform3D rotation;//3D旋转 // rotation = CATransform3DMakeTranslation(0 ,50 ,20); rotation = CATransform3DMakeRotation( M_PI_4 , 0.0, 0.7, 0.4); //逆时针旋转

  rotation = CATransform3DScale(rotation, 0.8, 0.8, 1);

  rotation.m34 = 1.0/ 1000;

  cell.layer.shadowColor = [[UIColor redColor]CGColor]; cell.layer.shadowOffset = CGSizeMake(10, 10); cell.alpha = 0;

  cell.layer.transform = rotation;

  [UIView beginAnimations:@"rotation" context:NULL]; //旋转时间 [UIView setAnimationDuration:0.6];

  cell.layer.transform = CATransform3DIdentity; cell.alpha = 1; cell.layer.shadowOffset = CGSizeMake(0, 0); [UIView commitAnimations];

#pragma mark - UICollectionView 数据源

• (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView { return SectionCouton; } 我的

Snip20160718_18.png 这个界面在任何 app 都比较常见,所以没有用到静态单元格,而是用纯代码封装了一个控制器,即使在其他项目中依然可以快速搭建出类似的界面

• (NSMutableArray *)groups { if (_groups == nil) { _groups = [NSMutableArray array]; }

  return _groups; }

• (instancetype)init { return [self initWithStyle:UITableViewStyleGrouped]; } // 返回有多少组

• (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{ return self.groups.count; }

// 返回每一组有多少行

• (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { // 获取当前的组模型 GPSettingGroup *group = self.groups[section];

  return group.items.count; }

• (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // 1.创建cell GPSettingCell *cell = [GPSettingCell cellWithTableView:tableView style:UITableViewCellStyleValue1];

  // 获取对应的组模型 GPSettingGroup *group = self.groups[indexPath.section];

  // 获取对应的行模型 GPSettingItem *item = group.items[indexPath.row];

  // 2.给cell传递模型 cell.item = item;

  return cell; }

// 返回每一组的头部标题

• (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { // 获取组模型 GPSettingGroup *group = self.groups[section];

  return group.header; }

• (NSString *)tableView:(UITableView *)tableView titleForFooterInSection:(NSInteger)section { // 获取组模型 GPSettingGroup *group = self.groups[section];

  return group.footer; }

// 选中cell的时候调用

• (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // 取出对应的组模型 GPSettingGroup *group = self.groups[indexPath.section];

  // 取出对应的行模型 GPSettingItem *item = group.items[indexPath.row];

  if (item.operation) {

    item.operation(indexPath);
    return;
  

  } // 判断下是否需要跳转 if ([item isKindOfClass:[GPSettingArrowItem class]]) {

    // 箭头类型,才需要跳转
  
    GPSettingArrowItem *arrowItem = (GPSettingArrowItem *)item;
  
    if (arrowItem.destVcClass == nil) return;
  
    // 创建跳转控制器

• (void)setUpAccessoryView { if ([_item isKindOfClass:[GPSettingArrowItem class]]) { // 箭头 self.accessoryType = UITableViewCellAccessoryDisclosureIndicator; }else{ self.accessoryView = nil; self.accessoryType = UITableViewCellAccessoryNone; } } 最后说两句 由于代码量较大,所以还是上源码吧,源码地址
