这可能是一个愚蠢的问题,但我现在真的一直在与它斗争一分钟。我以编程方式创建了一个UITableView,所有数据都完美流动,现在我只想在桌面上添加一个静态图像,似乎无法做到:-(我知道这可能是非常基本但我真的需要有人来帮助我。

好吧,我最终在代码中完成了它,现在是。

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {

    UIImage *myImage = [UIImage imageNamed:@"ranking_bar.png"];
    UIImageView *imageView = [[[UIImageView alloc] initWithImage:myImage] autorelease];
    imageView.frame = CGRectMake(10,10,320,30);

    return imageView;

}

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    return 30;
}

通常你会创建一个UITableViewController,它将委托表的工作方式(这是numberOfSectionsInTableView,numberOfSectionsInTableView等)的方法。为了使单元格本身不同,默认情况下你需要创建一个UITableViewCell的子类

customcell.h

#import <UIKit/UIKit.h>


@interface CustomCell : UITableViewCell {

    UILabel *primaryLabel;
    UIImageView *myImageView;
}

@property (nonatomic, retain) UILabel *primaryLabel;
@property (nonatomic, retain) UIImageView *myImageView;
@end

customcell.m

#import "CustomCell.h"


@implementation CustomCell
@synthesize primaryLabel,myImageView;
- (id)initWithFrame:(CGRect)frame reuseIdentifier:(NSString *)reuseIdentifier {

    if (self = [super initWithFrame:frame reuseIdentifier:reuseIdentifier]) {

        // Initialization code

        primaryLabel = [[UILabel alloc]init];

        primaryLabel.textAlignment = UITextAlignmentLeft;

        primaryLabel.font = [UIFont systemFontOfSize:20];

        primaryLabel.backgroundColor = [UIColor blackColor];

        primaryLabel.textColor = [UIColor redColor];

        myImageView = [[UIImageView alloc]init];

        [self.contentView addSubview:primaryLabel];

        [self.contentView addSubview:myImageView];

    }

    return self;

}

- (void)layoutSubviews {

    [super layoutSubviews];

    CGRect contentRect = self.contentView.bounds;

    CGFloat boundsX = contentRect.origin.x;

    CGRect frame;

    frame= CGRectMake(boundsX+10 ,0, 300, 40);

    myImageView.frame = frame;

    frame= CGRectMake(boundsX+70 ,5, 200, 25);

    primaryLabel.frame = frame;


}
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)dealloc
{
    [myImageView release];
    [primaryLabel release];
    [super dealloc];
}

- (void)didReceiveMemoryWarning
{
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}

#pragma mark - View lifecycle

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
}

然后回到你的UITableViewController:cellforrowatindexpath方法你应该分配你的自定义单元格

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];

    }

    // Configure the cell...
    NSInteger row = [indexPath row];
    NSString *pathString= [snowBoardArray objectAtIndex:row];
    NSString *string2= @"Cell";
    pathString = [pathString stringByAppendingString:string2];



    cell.primaryLabel.text=[snowBoardArray objectAtIndex:row];
    NSString *filePath = [[NSBundle mainBundle] pathForResource:pathString ofType:@"png"];
    UIImage *theImage = [[UIImage alloc] initWithContentsOfFile:filePath];
    cell.myImageView.image = theImage;
    [theImage release];

    return cell;
}

    -(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section 
{  

    UIImageView *imageView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"urImg.png"]] autorelease];  
    imageView.frame = CGRectMake(5,5,320,30);
    return imageView;
}

(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section   
  {   
      return 30;  
 }
