How do we create a universal search textfield like in iOS 7 safari. I know how to create a Google search field, but how can I create one textfield which has both Google search and URL search.
Google Searchfield:
-(void)SearchButtonClicked {
NSString *query = [maintext.text stringByReplacingOccurrencesOfString:@" " withString:@"+"];
NSString *urlString = [NSString stringWithFormat:@"%@", query];
// remember to change the view controller class in storyboard
MyWebViewController *webViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"WebView"];
// urlString is a public property on MyWebViewController
webViewController.urlString = urlString;
[self presentViewController:webViewController animated:YES completion:nil];
}
- (IBAction)SearchButton:(id)sender {
NSString *query = [maintext.text stringByReplacingOccurrencesOfString:@" " withString:@"+"];
NSString *urlString = [NSString stringWithFormat:@"http://www.google.com/search?q=%@", query];
// remember to change the view controller class in storyboard
MyWebViewController *webViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"WebView"];
// urlString is a public property on MyWebViewController
webViewController.urlString = urlString;
[self presentViewController:webViewController animated:YES completion:nil];
}
My Webview controller:
#import "MyWebViewController.h"
#import "ViewController.h"
#import <Social/Social.h>
#import "SIAlertView.h"
#import "TTAlertView.h"
#import "ETActivityIndicatorView.h"
@implementation MyWebViewController {
}
@synthesize searchField;
@synthesize webView;
ETActivityIndicatorView * etActivity;
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
NSURL *url = [NSURL URLWithString:self.urlString];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:request];
}
-(void)webView:(UIWebView *)webBlog didFailLoadWithError:(NSError *)error{
if ([error code] != -999) {
NSLog(@"Could not load the dumb webPage");
//show error alert, etc.
TTAlertView *alert = [[TTAlertView alloc] initWithTitle:@"Internet Error"
message:@"Searched cannot open the page because your iPhone is not connected to the internet."
delegate:self
cancelButtonTitle:@"Dismiss"
otherButtonTitles:nil];
[alert show];
[etActivity setHidden:YES];
}else{
NSLog(@"Could not load the dumb web page...just might blame user!");
}
}
//Called whenever the view starts loading something
- (void)webViewDidStartLoad:(UIWebView *)webView {
[etActivity startAnimating];
[etActivity setHidden:NO];
}

[etActivity stopAnimating];
