Question

我有一个重要的问题。我正在创建一个iPhone应用程序。我有一个带有goBack，goForward和reload的UIWebView（https://www.google.de/）。现在，我想要一个按钮，例如条形按钮项目名为Home或Homepage，用于在此WebView中打开URL（https://www.google.de/），以返回主页。我怎样才能做到这一点？我怎么能说＆＃34;用于在WebView中打开链接的按钮？我要求回答。

//  ViewController.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
@property (nonatomic, strong) IBOutlet UIWebView *site   ;
@end



//  ViewController.m

#import "ViewController.h"

@interface ViewController ()
@end
@implementation ViewController
-(IBAction)refresh:(id)sender; {

    NSURL *url=[NSURL URLWithString: @"https://www.google.de/"]; NSURLRequest * requestURL=[NSURLRequest requestWithURL:url]; [_site loadRequest:requestURL];

}
- (void)viewDidLoad {

    [self refresh:self];

    [super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.

}
- (void)didReceiveMemoryWarning {

    [super didReceiveMemoryWarning];

// Dispose of any resources that can be recreated.

}
@end

UIWebView有方法goBack和goForward。您可以进行操作并将其与条形按钮绑定，以便随时返回。

- (IBAction)goBack:(id)sender {
    [_site goBack];
}

- (IBAction)goForward:(id)sender {
    [_site goForward];
}

- (IBAction)goHomepage:(id)sender {
    NSURL *url=[NSURL URLWithString: @"https://www.google.de/"]; 
    NSURLRequest *requestURL=[NSURLRequest requestWithURL:url]; 
    [_site loadRequest:requestURL];
}
