我对UITableViewCellStyle有点混淆。我想创建一个像这样的自定义UITableViewCell:
但是当我运行应用程序时,文本和图像不会出现在单元格中。在Storyboard中,我将TableView样式放到了' Custom'。
我做错了什么?
MainTableViewController
#import "MainTableViewController.h"
#import "CustomMainCell.h"
static NSString *CellIdentifier = @"MainCell";
@interface MainTableViewController ()
//
@property(nonatomic, strong) NSArray *dataSource;
//
@property(nonatomic, strong) NSArray *iconsSource;
@end
@implementation MainTableViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.title = @"Currículum Vitae";
// Inicializo los arrays con los datos
self.dataSource = @[@"PERFIL",@"EXPERIENCIA",@"EDUCACIÓN",@"HABILIDADES",@"INTERESES"];
self.iconsSource = @[@"perfil.png",@"experiencia.png",@"educacion.png",@"habilidades.png",@"intereses"];
// Register Class for Cell Reuse Identifier
[self.tableView registerClass:[CustomMainCell class] forCellReuseIdentifier:CellIdentifier];
// This will remove extra separators from tableview
self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
// Eliminio las líneas que separan las celdas
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return self.dataSource.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
CustomMainCell *cell = (CustomMainCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell == nil) {
cell = [[CustomMainCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell...
cell.title.text = self.dataSource[indexPath.row];
cell.icon.image = self.iconsSource[indexPath.row];
return cell;
}
CustomMainCell.h
@interface CustomMainCell : UITableViewCell
//
@property (weak, nonatomic) IBOutlet UILabel *title;
//
@property (weak, nonatomic) IBOutlet UIImageView *icon;
@end
CustomMainCell.m
#import "CustomMainCell.h"
@implementation CustomMainCell
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
self.textLabel.textColor = [UIColor brownColor];
}
return self;
}
- (void)awakeFromNib
{
// Initialization code
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
@end
答案 0 :(得分:1)
你不应该:
// Register Class for Cell Reuse Identifier
[self.tableView registerClass:[CustomMainCell class] forCellReuseIdentifier:CellIdentifier];
因为在取消归档视图控制器时从故事板中注册了单元格。通过注册该类,您将删除存档(NIB)注册。
另外:
if (cell == nil) {
cell = [[CustomMainCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
不应该被要求,因为您将始终获得有效的单元格(因为标识符已注册)
