我有1个部分和6行的tableview。我想在第一行中应用UITableViewCell的自定义单元格样式子类,而其余各行具有默认的UITableViewCell。当我运行该应用程序时,它不会以自定义单元格样式显示第一行的内容。我尝试使用return cell2而不是cell来引用第一行中的自定义样式,但是它仍然无法正常工作。
imageCellCell.h
#import <UIKit/UIKit.h>
@interface imageCellCell : UITableViewCell
@property (nonatomic, strong) UIView *view;
@property (nonatomic, strong) UILabel *label1;
@property (nonatomic, strong) UILabel *label2;
@property (nonatomic, strong) UIImageView *prodimage;
@end
imageCellCell.m
#import "imageCellCell.h"
@implementation imageCellCell
@synthesize view;
@synthesize label1;
@synthesize label2;
@synthesize prodimage;
- (id)initWithStyleUITableViewCellStyle)style reuseIdentifierNSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
view = [[UIView alloc] initWithFrame:self.frame];
[self addSubview:view];
// initiate image
prodimage = [[UIImageView alloc]initWithFrame:CGRectMake(30,2, 180, 180)];
// initiate label1 with position (10,10,150,20)
label1 = [[UILabel alloc] initWithFrame:CGRectMake(10,10,150,20)];
// initiate label2 with position (170,10,150,20)
label2 = [[UILabel alloc] initWithFrame:CGRectMake(170,10,150,20)];
[view addSubview:prodimage];
[view addSubview:label1];
[view addSubview:label2];
}
return self;
}
@end

问题是您始终都返回cell 。相反,如果该行为0,则返回cell2 (imageCellCell 实例)。
对您的代码进行了修改(请注意,该代码尚未经过完全测试):
- (UITableViewCell *)tableViewUITableView *)tableView cellForRowAtIndexPathNSIndexPath *)indexPath
{
NSString *CellIdentifier;
NSString *CellIdentifierimg;
UITableViewCell *cell;
if (cell == nil) {
if (indexPath.row == 1) {
cell = [[imageCellCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifierimg];
} else if (indexPath.row == 2) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
}
switch ([indexPath row])
{
case 0:
{
imageCellCell *firstRowCell = (imageCellCell *)cell;
[firstRowCell.prodimage setImage: [UIImage imageNamed"test1.jpg"]];
[firstRowCell.label1 setText"text"];
[firstRowCell.label2 setText"more text"];
firstRowCell.accessoryType = UITableViewCellAccessoryNone;
break;
}
case 1:
{
NSString *labelText = [self.data objectAtIndex:indexPath.row];
cell.textLabel.text = labelText;
break;
}
case 2:
{
cell.textLabel.text = @"Manufacturer";
break;
}
case 3:
{
cell.textLabel.text = @"Overall Score";
break;
}
case 4:
{
cell.textLabel.text = @"Description";
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
break;
}
case 5:
{
cell.textLabel.text = @"Video";
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
break;
}
}
return cell;
}
