我有一個標籤的情況!我做了一個tableView,它在解析時與一個數據表相關聯。當我選擇行視圖控制器傳遞到視圖,但值是!我所有的NSLog都指定了數據通過的事實!但我無法在viewController的標籤上顯示該圖標!請幫助..我錯過了什麼?所有的連接都沒有與文件的所有者。這些都是我的文件..無法顯示UILabel -xcode
-(void) tableView: (UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
PFObject *object = [self.objects objectAtIndex:indexPath.row];
NSInteger row = [indexPath row];
NSLog(@"%i",row);
MyTableViewDetail * MTD = [[MyTableViewDetail alloc] initWithNibName:@"MyTableViewDetail" bundle:nil];
NSLog(@"text=%@",[object objectForKey:@"columntext"]);
MTD.label1 = [object objectForKey:@"columntext"];
NSLog(@"label1= %@",MTD.label1);
[self.navigationController pushViewController:MTD animated:YES];
//tableView.backgroundColor =[UIColor clearColor];
}
所有我的NSLog的都指向正確的方向。但由於某些原因,LABEL1不顯示值。這裏是我的其他文件..
#import "MyTableViewDetail.h"
#import "MyTableController.h"
@interface MyTableViewDetail()
@end
@implementation MyTableViewDetail
@synthesize label1;
@synthesize imagedetail;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad{
[super viewDidLoad];
}
- (void)viewDidUnload
{
[self setLabel1:nil];
[self setImagedetail:nil];
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
@end
和我的.h:
#import <UIKit/UIKit.h>
#import <Parse/Parse.h>
#import "MyTableController.h"
@interface MyTableViewDetail : UIViewController{
}
@property (strong, nonatomic) IBOutlet UILabel *label1;
@property (strong, nonatomic) IBOutlet UIImageView *imagedetail;
@end
試過也..它不工作..當我運行MTD.label1 = ... NSLog(@「label1 =%@」,MTD.label1);顯示我想要的結果。當我運行MTD.kabel1.text = ... NSLog顯示「null」。所以我真的不知道我在這一點上錯過了什麼。 – snksnk
你可以顯示實際的NSLog()輸出嗎? –
這些是NSLogs與MTD.label1.text = .. 2012-08-26 15:15:08.790 pyxida3 [7427:c07] 0 2012-08-26 15:15:08.790 pyxida3 [7427:c07] text = test3 2012-08-26 15:15:08.790 pyxida3 [7427:c07] label1 =(null) and these this with MTD.label1 = ... 2012-08-26 15:16:57.457 pyxida3 [7470:c07] 0 2012-08-26 15:16:57.457 pyxida3 [7470:c07] text = test3 2012-08-26 15:16:57.457 pyxida3 [7470:c07] label1 = test3 – snksnk
