uiwebview without interface builder
I've to switch a part of my app: I will implement a web view insread of a picture (imageview).
So I tried to make it with the interface builder but there is too many errors so I prefer to use code!
for the pictures, I user those lines :
image = [UIImage imageWithData:[NSData data开发者_运维知识库WithContentsOfURL:url]];
self.imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(0,64,320,367);
[self.view addSubview:imageView];
[self.imageView release];
Now, I tried to use this code but nothing's showed:
@property (nonatomic, retain) IBOutlet UIWebView *webView;
...
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.fr"]]];
[self.view addSubview:webView];
If you know how to make .... would be nice for me,
THANKS!
Declare in your h file:
UIWebView *contentWebView;
And also tell to your viewController that you will implement <UIWebViewDelegate>
In viewDidLoad Add:
contentWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
contentWebView.delegate = self;
contentWebView.multipleTouchEnabled = YES;
contentWebView.scalesPageToFit = NO;
[self.view addSubview:contentWebView];
In dealloc don't forget to release the webView:
[contentWebView release];
And implement the delegate methods:
#pragma mark -
#pragma mark WebViewDelegates
- (void)webViewDidStartLoad:(UIWebView *)webView{
}
- (void)webViewDidFinishLoad:(UIWebView *)webView{
}
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error{
}
And also you need to load an request. You can doit in viewDidLoad after you have added the webView to your view:
[contentWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.apple.com/"]]];
adjust the frame as u needed and if add anything like imageview as subview to webview then u have to use bringsubviewtofront function.
- (void) initUIWebView {
NSLog(@"DetailViewController->initUIWebView {");
UIWebView *aWebView;
// init and create the UIWebView
aWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 400)];
aWebView.autoresizesSubviews = YES;
aWebView.autoresizingMask=(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth);
//set the web view delegates for the web view to be itself
[aWebView setDelegate:self];
//Set the URL to go to for your UIWebView
NSString *urlAddress = @”http://www.google.com”;
//Create a URL object.
NSURL *url = [NSURL URLWithString:urlAddress];
//URL Requst Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
//load the URL into the web view.
[aWebView loadRequest:requestObj];
//add the web view to the content view
[self.view addSubview:aWebView];
[aWebView release], aWebView = nil;
}
- (void)viewDidLoad {
[self initUIWebView]; // <<<<<<<<<<<< this calls the UIWebView Function
[super viewDidLoad];
}
