我创建了一个名为“CustomPreviCell”的自定义单元格(它的 NIb 名称和此 NIB 中单元格的标识符)。我的 customCell 包含 6 个标签和一个 imageView。与此单元格对应的 .m 文件如下:
@interface CustomPreviCell : UITableViewCell
@property (weak, nonatomic) IBOutlet UIImageView *iconImageView;
@property (weak, nonatomic) IBOutlet UILabel *weatherLabel;
@property (weak, nonatomic) IBOutlet UILabel *detailOneLabel;
@property (weak, nonatomic) IBOutlet UILabel *detailTwoLabel;
@property (weak, nonatomic) IBOutlet UILabel *dayNumberLabel;
@property (weak, nonatomic) IBOutlet UILabel *dayTextLabel;
@property (weak, nonatomic) IBOutlet UILabel *monthLabel;
@end
和实施:
#import "CustomPreviCell.h"
@implementation CustomPreviCell
@synthesize iconImageView;
@synthesize weatherLabel;
@synthesize detailOneLabel;
@synthesize detailTwoLabel;
@synthesize dayNumberLabel;
@synthesize dayTextLabel;
@synthesize monthLabel;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
}
return self;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
}
@end
现在,我想在 tableView 中显示这个单元格(当然!)。所以在我的故事板中,我创建了一个带有一个 CustomCell 原型的新 UITableView,我将视图引用到我的类“SinglePrevViewController”,它扩展了“UITableViewController”。我为 tableView 实现了经典方法(numberOfRowsInSection:等......)。
在“cellForRowAtIndexPath”方法中,我想创建、初始化和显示我的自定义单元格,所以我写道:
NSString *simpleTableIdentifier = @"CustomCellPrevi";
CustomPreviCell *cell = (CustomPreviCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCellPrevi" owner:self options:nil];
for (id currentObject in topLevelObjects){
if ([currentObject isKindOfClass:[CustomPreviCell class]]){
cell = (CustomPreviCell *)currentObject;
NSString * iconName = [self loadIcon:indexPath.row];
[cell.iconImageView setImage:[UIImage imageNamed:iconName]];
cell.detailOneLabel.text = [[NSString alloc] initWithFormat:@"%@°C - %@mm",[descriptor.temperature objectAtIndex:indexPath.row], [descriptor.precipitations objectAtIndex:indexPath.row]];
cell.detailTwoLabel.text = [[NSString alloc] initWithFormat:@"%@ (%@) km/h - %@hPa",[descriptor.vent objectAtIndex:indexPath.row],[descriptor.rafales objectAtIndex:indexPath.row], [descriptor.pression objectAtIndex:indexPath.row]];
cell.weatherLabel.text = [descriptor.temps objectAtIndex:indexPath.row];
NSDictionary * date = [self getDateComponentsFromXMLDate:[descriptor.date objectAtIndex:indexPath.row]];
if([[date valueForKey:@"dayNumber"] intValue] %2 == 0)
[cell.contentView setBackgroundColor:[UIColor colorWithWhite:1 alpha:0.0]];
else
[cell.contentView setBackgroundColor:[UIColor colorWithWhite:1 alpha:0.15]];
cell.dayTextLabel.text = [date valueForKey:@"dayText"];
cell.dayNumberLabel.text = [[NSString alloc] initWithFormat:@"%@ %@",[date valueForKey:@"dayNumber"],[date valueForKey:@"month"]];
cell.monthLabel.text = [date valueForKey:@"hour"];
}
}
return cell;
让我们启动我的应用程序:它工作正常!我的 tableView 包含我的 CustomPrevCells 并正确显示内容。但是......当我想从这些单元格中推送一个新的 viewController 时,它不起作用。我已将我的 customCell(从情节提要中 TableView 中的单元格)连接到新的 viewcontroller(名为 DetailPrevViewcontroller),但它什么也没做。我的 customCell 刚刚被选中。
请帮忙 :)
编辑1:
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
NSLog(@"Hey !");
if([segue.identifier isEqualToString:@"propertiesSegue"])
{
NSLog(@"Hello");
SingleVillePropertiesViewController * destinationController = [segue destinationViewController];
[destinationController setVille:ville];
}
else if([segue.identifier isEqualToString:@"detailPreviSegue"])
{
DetailPreviViewController * destController = [segue destinationViewController];
[[self navigationController] pushViewController:destController animated:YES];
//TODO : set previDescriptor to my destController but it's not important
// for this problem.
}
}
编辑 2: 好的,我还没有解决这个问题,但我通过这样做摆脱了它:
1/ 为要推送的视图控制器创建一个新的 nib(不在情节提要中)
2/ 将它设置为您的 ViewController 的类(在我的情况下为 DetailPrevViewController)和 FilesOwner 的视图到 NIB 视图
3/ 使用 navigationController 从方法“didSelectRowAtPath”推送视图。
我不喜欢这种方式进行,但它是目前唯一可行的方式......
