现在许多App的首页都是采用的九宫格形式,一级菜单(标题)下面跟二级菜单(图标+标题)。对于这样一个页面来说,collectionView能够极好的适配这样的形式。一级菜单使用section的headView实现,二级菜单使用collectionViewCell实现。
代码类似这样下:
//创建ColletionView
- (void) makeColletionView{
self.collectionView = [[UICollectionView alloc] initWithFrame:CGRectMake(15, STATUSBAR_HEIGHT + 40, SCREEN_WIDTH - 30, SCREEN_HEIGHT - STATUSBAR_HEIGHT - 40) collectionViewLayout:self.layout];
self.collectionView.backgroundColor = [UIColor whiteColor];
self.collectionView.dataSource = self;
self.collectionView.delegate = self;
[self.view addSubview: self.collectionView];
// [self.collectionView registerNib:[UINib nibWithNibName:@"ShopManageCollectionViewCell" bundle:nil] forCellWithReuseIdentifier:@"ShopManageCollectionViewCell"];
[self.collectionView registerClass:[ShopManageCell class] forCellWithReuseIdentifier:@"cell"];
//注册头视图
//[self.collectionView registerClass:[UICollectionReusableView class] forSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:@"headview"];
//注册尾视图
//[self.collectionView registerClass:[UICollectionReusableView class] forSupplementaryViewOfKind:UICollectionElementKindSectionFooter withReuseIdentifier:@"footview"];
}
- (UICollectionViewFlowLayout *) layout{
if (_layout == nil) {
_layout = [[UICollectionViewFlowLayout alloc]init];
//_layout.itemSize = CGSizeMake((ScreenWidth - 20)/3, 25);
//_layout.minimumLineSpacing = -20;
_layout.sectionInset = UIEdgeInsetsMake(0, 0, 10, 0);
_layout.headerReferenceSize = CGSizeMake(SCREEN_WIDTH, 30);
}
return _layout;
}
//Delegate
//一级菜单
- (NSInteger) numberOfSectionsInCollectionView:(UICollectionView *)collectionView{
return 3;
}
//二级菜单
- (NSInteger) collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section{
return 3;
}
//一级菜单实现
- (UICollectionReusableView *)collectionView:(UICollectionView *)collectionView
viewForSupplementaryElementOfKind:(NSString *)kind
atIndexPath:(NSIndexPath *)indexPath {
UICollectionReusableView *reuseablebiew = nil;
if ([kind isEqualToString:@"UICollectionElementKindSectionHeader"]) {
//这是头视图
[self.collectionView registerClass:[UICollectionReusableView class] forSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:[NSString stringWithFormat:@"headview %@",indexPath]];
UICollectionReusableView *headeview = [collectionView dequeueReusableSupplementaryViewOfKind:kind withReuseIdentifier:[NSString stringWithFormat:@"headview %@",indexPath] forIndexPath:indexPath];
//添加Label
UILabel *headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 0, SCREEN_WIDTH - 80, 30)];
headerLabel.font = [UIFont systemFontOfSize:17 weight:UIFontWeightSemibold];
headerLabel.textColor = UIColorFromHex(0x4D4D4D);
//添加边缘修饰图

}else if (indexPath.section == 2){

}else{
headerLabel.text = [NSString stringWithFormat:@" "];
}
[headeview addSubview:borderView];
[headeview addSubview:headerLabel];
reuseablebiew = headeview;
}
return reuseablebiew;
}
//二级菜单实现
- (UICollectionViewCell *) collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{
// ShopManageCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"ShopManageCell" forIndexPath:indexPath];
ShopManageCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"cell" forIndexPath:indexPath];
if (indexPath.section == 0) {
if(indexPath.row == 0){

最近在做一个新项目的时候有这么一个情况,登录之后进入首页有五个角色,每个角色的菜单都会不同。如果只有细微的差别的话,我会选择在Delegate里面添加一些判断。但是我接到的设计方案五个角色菜单的差距还是比较大的。如果要硬写判断可能会有比较大的代码量,且复杂易出错。对阅读代码也会不太友好。所以我想了别的办法控制。
想法一:
仿照多局点的方式,建立多个主页文件(HomePage),在登录后判断完权限以后直接加载对应角色的主页面。这样搞的话至少看起来会舒服一点,没有那么多的判断,但是肉眼可见的增加了代码量和维护成本。如果只有少数几个角色,且角色差距极大我觉得这样的方式还不错。但角色多的话这种方式就不合适了。
想法二:
因为上一个想法的失败,所以回归到只用一个文件来做判断的路子上。那就一定是要写判断的,但能不能不在Delegate里面写判断呢。Delegate里面清清爽爽的才是真香。
然后想到了用dataSource就可以了呀(section表示一级标题,rows表示二级标题),习惯性处理简单主界面的我都快要忘了还有DataSources了。那就开始搞起来吧。cell保持不动,也就我们的dataSources里面需要有icon和title,还需要有一个字段来表示最后的跳转。那就新建一个类来表示吧 homePageModel
。
最开始我想在homePageModel添加image,title和controller三个字段来适应上面的要求。但动手的时候突然觉得controller可能会有些问题,因为我们跳转的时候可能会传不同的参数。所以决定把这个任务交给主页来做,在
homePageModel里面用枚举定义一个HomePageCode
。通过code来判断执行怎样的跳转。
代码如下:
//HomePageModel.h
typedef NS_ENUM(NSInteger , HomePageCode) {
//日常工作
HomePage_AlarmUpload = 1,//警情上报
HomePage_AlarmAccept = 2,//警情受理
HomePage_AlarmAssist = 3,//协查协办
HomePage_AlarmDistribute = 4,//协查派发
HomePage_Patrol = 5,//安防巡逻
HomePage_PatrolChck = 6,//巡防督查
//常用功能
HomePage_ClockIn = 7,//签到打卡
HomePage_News = 8,//新闻资讯
HomePage_Scan = 9,//扫一扫
HomePage_RankingList = 10,//排行榜
HomePage_StaffManage = 11,//人员管理
HomePage_VolunteerCheck = 12,//志愿者审核
//参加活动
HomePage_Actity = 13,//活动报名
HomePage_Volunteer = 14,//志愿者申请
//信息处理
HomePage_InfoSearch = 15,//信息查询
HomePage_InfoDistribute = 16,//信息发布
//学习培训
HomePage_SafeKnowledge = 17,//安全小知识
HomePage_Study = 18,//学习培训
};
@interface HomePageModel : NSObject
@property (nonatomic, strong) NSString *name;
@property (nonatomic, strong) UIImage *image;
//@property (nonatomic, strong) UIViewController *controller;
@property (nonatomic, assign) HomePageCode code;
+ (HomePageModel *)addModelWithName:(NSString *)name ImageName:(NSString *)imageName Code:(HomePageCode)code;
@end
//HomePageModel.m
+(HomePageModel *)addModelWithName:(NSString *)name ImageName:(NSString *)imageName Code:(HomePageCode)code{
HomePageModel *homepage = [[HomePageModel alloc] init];
homepage.name = getLocalizedString(name, nil);
homepage.image = [UIImage imageNamed:imageName];
homepage.code = code;
return homepage;
}
这时我又有了两个想法:
- 想法一:再添加一个HomePageGroup(字段有name和array)表示一级菜单,name表示一级菜单的标题,array表示每个一级菜单的内容,即二级菜单。用一个数组来存放一级菜单,数组的count就是一级菜单的数量。
- 想法二:然后用一个字典来保存每个角色的主页菜单,
key
代表一级菜单, value
表示二级菜单。然后就可以判断字段中key的数量来表示一级菜单的数量,内容表示一级菜单的title。通过rows取到二级菜单的详情。
写完之后觉得觉得代码还是太长了,几个角色里面会有相同的功能点,就重复了多次。然后我决定把所有的item对照上面的枚举定义全部写到 HomePageModel
里面。这样就省掉了重复的添加过程。然后再新建一个 HomePageMenu
类来表示菜单整体,定义一个枚举来表示角色名称,并定义一个方法通过角色来获取menu数组。这样在主页里面就可以通过一行代码搞定了。
代码如下:
// HomePageModel.h
// 菜单功能点配置
#import
typedef NS_ENUM(NSInteger , HomePageCode) {
//日常工作
HomePage_AlarmUpload = 1,//警情上报
HomePage_AlarmAccept = 2,//警情受理
HomePage_AlarmAssist = 3,//协查协办
HomePage_AlarmDistribute = 4,//协查派发
HomePage_Patrol = 5,//安防巡逻
HomePage_PatrolChck = 6,//巡防督查
//常用功能
HomePage_ClockIn = 7,//签到打卡
HomePage_News = 8,//新闻资讯
HomePage_Scan = 9,//扫一扫
HomePage_RankingList = 10,//排行榜
HomePage_StaffManage = 11,//人员管理
HomePage_VolunteerCheck = 12,//志愿者审核
//参加活动
HomePage_Actity = 13,//活动报名
HomePage_Volunteer = 14,//志愿者申请
//信息处理
HomePage_InfoSearch = 15,//信息查询
HomePage_InfoDistribute = 16,//信息发布
//学习培训
HomePage_SafeKnowledge = 17,//安全小知识
HomePage_Study = 18,//学习培训
