A plugin of UITableView can easy manage models and auto calculate cell height with autolayout
use cocoapods
pod 'NJEasyTable'
#import "UITableView+NJEasyTable.h"
You can add sections and rows to nj_TableModel.
[self.tableView.nj_TableModel addSection:({
NJEasyTableSection *section = [[NJEasyTableSection alloc] initWithModel:nil];
[section addRow:({
NJEasyTableRow *row = [[NJEasyTableRow alloc] initWithModel:model];
row.cellHeight = 44;
row;
})];
section;
})];
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [tableView.nj_TableModel numberOfSections];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [tableView.nj_TableModel numberOfRowsInSection:section];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *identifier = @"cellIdentifier";
TestCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil) {
cell = [[TestCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
}
id model = [tableView.nj_TableModel modelAtIndexPath:indexPath];
[cell configWithModel:model];
return cell;
}
If you use autolayout in UITableViewCell. you doesn't need to calculate cell height manually. Cell height value can like this:
// regist a cell for calculate cell height
TestCell *cell = [[TestCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil];
[self.tableView nj_registAutolayoutCell:cell forAutomaticCalculationHeightIdentifier:@"testCell"];
// implement in heightForRow
- (GFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
CGFloat height = [tableView nj_intrinsicHeightAtIndexPath:indexPath
forIdentifier:@"testCell"
configCellBlock:^(TestCell *cell, id model) {
[cell configWithModel:model];
}];
return height;
}
