【问题描述】:
伙计们
我正在做 this 教程,但在编写代码后,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!请问,谁能帮帮我?
@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;
}
【问题讨论】:
-
检查名称是否与您在 Supporting Files 文件夹中添加的名称相同
-
你设置了 imageView IBOutletConnection 吗?
-
按照教程进行编码没有问题。请确保您将 IBOutletConnections 正确连接到 CustomCell 而不是 FilesOwner
-
您的代码是 nop... 但请参阅 IBOutlet 连接 .... 不要跟随“Sync”调用,请尝试调用“Asyc”调用.....developer.apple.com/library/ios/#samplecode/LazyTableImages/…
-
@Nims 名字相同
