RLCellModel

An elegant way to create an infomation TableView

In old days to create different function of rows in a TableView, you need to distinguish row function by indexPath , just like these:

if (indexPath.row == 1) {
        //do something
    }else if(indexPath.row == 2){
        //do something
    }
}

This can do , but when your product manager change some idea, remove or delete some rows, you will just became cracied about changing the old logic....

But with this RLCellModelManager, you can just

Use a model represent a row style and its function
DON'T NEED to distinguish row by if/else
Easy way to ADD or DELETE or MOVE any items in TableView

Here is THE CODE:

self.cellModelManager = [[RLCellModelManager alloc]
//Sometimes you just need one TableViewCell
//but you could override it with your specific RLCellModel
initWithGlobalCellIdentifier:NSStringFromClass([RLMineInfoTableViewCell class]) 
//Sometimes you just need one Cell Height, 
//but you could override it with your specific RLCellModel
globalHeight:[RLMineInfoTableViewCell cellHeight]
globalReuseCellBlock:^(RLMineInfoTableViewCell *cell, RLCellModel *cellModel) {

        //Do things you used to do in 
        //- (UITableViewCell *)tableView:(UITableView *)tableView
        //cellForRowAtIndexPath:(NSIndexPath *)indexPath;
        NSDictionary *cellDict = cellModel.cellGenerateRuleDict;
        NSString *title = [cellDict objectForKey:@"title"];
        NSNumber *cellType = [cellDict objectForKey:@"cellType"];
        cell.generalType = cellType.integerValue;
        cell.titleLabel.text = title;
    }
    customExtractCellModelBlock:^RLCellModel *(NSArray *cellModels, NSIndexPath *indexPath) {
        //Sometimes your TableView does not just have one section
        //(if you have one, just set this block to nil),
        //this Manager need to know how to extract cellModel from datasource
        //to do boring things for you
        return [[cellModels objectAtIndex:indexPath.section]objectAtIndex:indexPath.row];
    }];
    
self.cellModelManager.delegate = self;
self.tableView.delegate = self.cellModelManager;
self.tableView.dataSource = self.cellModelManager;

Let's see how to implement a row

//One Model represent a single Cell
RLCellModel *avatar = [RLCellModel new];

//You can retrieve this Dict in RLCellModelManager's GlobalReuseCellBlock 
avatar.cellGenerateRuleDict = @{@"cellType":@(GeneralTypeAvatar),
                                    @"title":@"头像",};
//If you set this property, it will override the manager's global height (only this row)
avatar.cellHeight = @([RLMineInfoTableViewCell cellHeightWithExtra]);

avatar.cellSelectedBlock = ^{
    //This block will trigger When the cell selected        
};

avatar.refreshBlock = ^(id cell){
    //This block will override the manager's global reuseBlock (only this row)
};

//Continue to create other cellModels

NSMutableArray *datasource = [NSMutableArray arrayWithArray:@[@[avatar, userName, realName, code,gender, qrcode],@[phone, cardNumber, recommandPerson]]];
//Just give the datasource to manager, then reload
self.cellModelManager.cellModels = datasource;
[self.tableView reloadData];
