在ViewController中初始化UIWebView的问题

我想初始化UIWebview内的WebViewController对象。我在初始化它时遇到了一些麻烦,并将其指向从之前ViewController发送给它的URL。

在我viewDidLoad的{​​{1}}中,我尝试使用以下内容对其进行初始化:

WebViewController

但是,这给我错误说明: UIWebView *tempWebview = [[UIWebView alloc]initWithFrame:theFrame]; NSURL *url = [NSURL URLWithString:_itemURL]; NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url]; self.myWebView = tempWebview; [tempWebview loadRequest:urlRequest]; _myWebView.delegate=self; [WebViewController loadRequest:urlRequest]; use of undeclared identifier'theFrame'

完整代码如下:

WebViewController.h:

no known class method for selector loadRequest

WebViewController.m:

#import <UIKit/UIKit.h>
#import "MatchCenterViewController.h"

@interface WebViewController : UIViewController

@property (strong, nonatomic) NSURL *itemURL;
@property (weak, nonatomic) IBOutlet UIWebView *myWebView;

@end

答案 0 :(得分:1)

首先,您需要定义您将.h文件中的UIWebView Delegate用作:

@interface WebViewController : UIViewController <UIWebViewDelegate>

如果您已在Xib文件中定义了webView,为什么要创建另一个UIWebView并将其分配给IBOutlet的webView?你可以这样做:

  self.myWebView.delegate = self;  //Note that I have set the delegate first before calling LoadRequest

  NSURL *url = [NSURL URLWithString:@"http://www.google.com"]; 

  NSURLRequest *request = [NSURLRequest requestWithURL:url]; 

  [self.myWebView setScalesPageToFit:YES];         

  [self.myWebView loadRequest:request];
