Question

我的应用程序有问题，所以当我把这个代码放在InfoViewController中并且我运行应用程序时，视图似乎是空的。我有一个表视图设置为静态单元格，3个部分，样式与标题分组每个部分，第一个单元格包含我用作谷歌搜索字段的文本字段，以及搜索按钮，第二个和第三个包含标签。我已连接故事板文件中的所有文本字段按钮和标签，以及文件所有者的委托。我应该实施任何其他方法吗？谢谢你的建议。

#import <UIKit/UIKit.h>

@interface InfoViewController : UIViewController <UINavigationControllerDelegate>

@property (weak, nonatomic) IBOutlet UITextField *googleSearchTextField;

@property (weak, nonatomic) IBOutlet UIButton *searchButton;

@property (weak, nonatomic) IBOutlet UILabel *Label1;

@property (weak, nonatomic) IBOutlet UILabel *Label2;

-(IBAction)googleSearch;

@end





#import "InfoViewController.h"

@end

@implementation InfoViewController

@synthesize googleSearchTextField;
@synthesize searchButton;
@synthesize Label1;
@synthesize Label2;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
    // Custom initialization
}
return self;
}

- (void)viewDidLoad
{
[super viewDidLoad];


self.Label1.text = @“Label1”;
self.Label2.text = @“Label2”;

}

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

- (BOOL)textFieldShouldReturn:(UITextField*)textField
{
[textField resignFirstResponder];
return YES;
}

-(IBAction)googleSearch
{
NSString *searchString=googleSearchTextField.text;
NSString *urlAdress = [NSString stringWithFormat:@"http://www.google.com/search?q=%@",         
searchString];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlAdress]];
}


@end

您需要添加tableViewDelegate方法和TableViewDataSource方法
