我有一个从 tableViewController 到带有 UILabel 的 viewController 的 segue 来显示文本（注释），但是，文本没有出现。
例如：
- (void)viewDidLoad
{
[super viewDidLoad];
list = [[NSMutableArray alloc] init];
wine *barbera =[[wine alloc] init];
[barbera setName:@"Barbera"];
[barbera setNotes:@"stuff about this..."];
[list addObject:barbera];
wine *chardonnay=[[wine alloc]init];
[chardonnay setName:@"Chardonnay"];
[chardonnay setNotes:@"stuff about this..."];
[list addObject:chardonnay];
wine *cheninBlanc =[[wine alloc]init];
[cheninBlanc setName:@"Chenin Blanc"];
[cheninBlanc setNotes:@"stuff about this... "];
[list addObject:cheninBlanc];
我的赛格：
-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
DescriptionWineViewController * dwvc= [segue destinationViewController];
[dwvc setCurrentWine :[self currentWine]];
}
我也尝试过：
-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
DescriptionWineViewController * dwvc= [segue destinationViewController];
[dwvc setNotes :[self notes]];
}
而 viewController 将继续：
@interface DescriptionWineViewController ()
@end
@implementation DescriptionWineViewController
@synthesize descriptionLabel;
@synthesize currentWine;
@synthesize notes;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
[descriptionLabel setText: [currentWine notes]];
}
如果您需要更多信息，请告诉我。
