Iphone自定义UITableViewCell

好久没写博客了，主要是最近一段时间忙于一个开发一个工程，现在工程开发的差不多了，打算把我在工程里面封装的一些工具类添上来，这篇把自定义的表格行添出来，废话不多说，直接看代码(代码里面用到的图片资源就不添出来了)：
.h文件：
[cpp]
#import <Foundation/Foundation.h> 
 
 
@interface MyTableCellUtil : NSObject { 
    UIColor *tabletextcolor;//自定义tablecell里面的自体颜色 
} 
 
@property(nonatomic,retain) UIColor *tabletextcolor;//自定义tablecell里面的自体颜色 
- (UIView *)tabcellview:(NSString *)text addImage:(UIImage *)myimage; 
 
- (UIView *)tabcellview:(NSString *)text; 
 
- (UIView *)tabcellview:(NSString *)text addImage:(UIImage *)myimage addusername:(NSString *)username; 
 
 
@end 

.m文件：
[cpp]
#import "MyTableCellUtil.h" 
 
 
@implementation MyTableCellUtil 
@synthesize tabletextcolor; 
 
-(void)dealloc{ 
    [tabletextcolor release]; 
    [super dealloc]; 
} 
 
-(id)init{ 
    [super init]; 
    tabletextcolor = [UIColor whiteColor]; 
     
    return self; 
}

    //行的背景图片

        bubbleImageView.frame = CGRectMake(0, 0, 310, bubbleText.frame.size.height+20);

@end 

调用的时候直接(记得设置每行的高度为当前自定义view的高度)：
[cpp]
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *CellIdentifier = @"Cell"; 
     
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) { 
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 
    } 
     
//    NSString *cellvalue; 
//    //为第一个section填充数据 
//   // if (indexPath.section == 0) { 
//    MyjsonResultUtil * myjsonUT = [self.mynotealljsonarray objectAtIndex:indexPath.section]; 
//    if ([self.mynotealljsonarray count]>0) { 
//        oneSectionData = myjsonUT.discriptionarray; 
//    }     
//        cellvalue = [oneSectionData objectAtIndex:indexPath.row]; 
//        cell.textLabel.text = cellvalue; 
//        //为每一行右边添加箭头 
//        cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton; 
//    cell.textLabel.font = [UIFont fontWithName:@"Verdana" size:15]; 
     
    MyjsonResultUtil * myjsonUT = [self.mynotealljsonarray objectAtIndex:indexPath.section]; 
    if ([self.mynotealljsonarray count]>0) { 
        oneSectionData = myjsonUT.discriptionarray; 
    }     
 
    cell.selectionStyle = UITableViewCellSelectionStyleNone; 
    cell.backgroundColor = [UIColor clearColor]; 
    UIImage *oneiavatar = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"apple" ofType:@"png"]]; 
    MyTableCellUtil *mytablecelluitl = [[MyTableCellUtil alloc]init]; 
    UIView *pinglunview = [mytablecelluitl tabcellview:[NSString stringWithFormat:@"%@",[oneSectionData objectAtIndex:indexPath.row]] addImage:oneiavatar]; 
     
    cell.backgroundView = pinglunview; 
//    [cell.contentView addSubview:pinglunview]; 
    [mytablecelluitl release]; 
 
    return cell; 
} 
 
//- (NSString *)tableView:(UITableView *)tableView  
//titleForHeaderInSection:(NSInteger)section{  
//  } 
 
 
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { 
//  return 70;   
    UIImage *oneiavatar = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"apple" ofType:@"png"]]; 
    MyTableCellUtil *mytablecelluitl = [[MyTableCellUtil alloc]init]; 
    UIView *pinglunview = [mytablecelluitl tabcellview:[NSString stringWithFormat:@"%@",[oneSectionData objectAtIndex:indexPath.row]] addImage:oneiavatar]; 
     
    [mytablecelluitl release]; 
    return pinglunview.frame.size.height; 
}
