伙计们

我正在做教程,但是在编写代码后,我在表格单元格中看不到任何图像->它们是白色的!

我在Supporting Files文件夹中添加了图片文件,再看一遍教程,但无法解决这个问题!拜托,谁能帮我解决这个问题?

@interface CarTableViewController ()

@end

@implementation CarTableViewController

@synthesize  carMakes = _carMakes;
@synthesize carImages = _carImages;
@synthesize carModels = _carModels;

- (id)initWithStyle:(UITableViewStyle)style
{
    self = [super initWithStyle:style];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.carMakes = [[NSArray alloc] initWithObjects:@"Chevy", @"BMW", @"Toyota", @"Volvo", @"Smart", nil];
    self.carModels = [[NSArray alloc] initWithObjects:@"Volt", @"Mini", @"Venza", @"S60", @"Fortwo", nil];
    self.carImages = [[NSArray alloc] initWithObjects:@"chevy_volt.jpg", @"mini_clubman.jpg", @"toyota_venza.jpg", @"volvo_s60.jpg", @"smart_fortwo.jpg", nil];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [self.carModels count];
}

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

    CarTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[CarTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
                                        reuseIdentifier:CellIdentifier];
    }
        cell.makeLabel.text = [self.carMakes objectAtIndex:[indexPath row]];
        cell.modelLabel.text = [self.carModels objectAtIndex:[indexPath row]];
        UIImage *carPhoto = [UIImage imageNamed:[self.carImages objectAtIndex: [indexPath row]]];
        cell.carImage.image = carPhoto;

    return cell;
}

尝试这个 ::

UIImage *im = [UIImage imageNamed:[NSString stringWithFormat:@"%@", self.carImages objectAtIndex: [indexPath row]]];
cell.imgCar.image = im;

如果仍然无法正常工作,则您的图像未正确复制到您的项目中。请删除并重新添加。

不要忘记@synthesize你的imageView

谢谢,快乐编码..

尝试设置方面适合 xib 或通过以下代码

cell.imgCar.image.imageViewContentmode = UIViewContentModeAspectFit;
