WebView, hey, lazy people dedicated, direct copy and paste can be used, frame adjustable

In the. h file of the controller

#import <UIKit/UIKit.h>

#import "FirstView.h"

@interface firstviewcontroller:uiviewcontroller<uiwebviewdelegate> {

UIWebView *web;

Uiactivityindicatorview *activityindicatorview;

UIView *opaqueview;

}

@property (nonatomic, strong) Firstview *FV;

@end

In. m, as follows:

#import "FirstViewController.h"

@interface Firstviewcontroller ()

@end

@implementation Firstviewcontroller

-(void) Loadview {

[Super Loadview];

SELF.FV = [[Firstview alloc] Initwithframe:[uiscreen mainscreen].bounds];

Self.view = SELF.FV;

}

-(void) Viewwillappear: (BOOL) Animated {

Self.tabBarController.navigationController.navigationBar.barTintColor = [Uicolor colorwithred:0.890 green:0.471 blue:0.118 alpha:1.000];

Self.tabBarController.navigationController.title = @ "Treasure in the air";

}

-(void) Viewdidload {

[Super Viewdidload];

web = [[UIWebView alloc]initwithframe:cgrectmake (0, 0, Self.view.frame.size.width, self.view.frame.size.height-40)];

[Does web setuserinteractionenabled:yes];//support interactivity

web.delegate=self;

[Web Setopaque:no]; Opaque is a non-transparent meaning

[Web setscalespagetofit:yes];//automatically scaled to fit the screen

[Self.view Addsubview:web];

Nsurl *url = [Nsurl urlwithstring:@ "http://www.baidu.com"];

[Web Loadrequest:[nsurlrequest Requestwithurl:url]];

2. Loading local File Resources

/* Nsurl *url = [Nsurl Fileurlwithpath:filepath];

Nsurlrequest *request = [Nsurlrequest Requestwithurl:url];

[WebView loadrequest:request];*/

3. Read in an HTML and write directly to an HTML code

NSString *htmlpath = [[[NSBundle mainbundle]bundlepath]stringbyappendingstring:@ "webapp/loadar.html"];

NSString *htmlstring = [NSString stringwithcontentsofurl:htmlpath encoding:nsutf8stringencoding Error:NULL];

[WebView loadhtmlstring:htmlstring Baseurl:[nsurl Fileurlwithpath:htmlpath];

Opaqueview = [[UIView alloc]initwithframe:[uiscreen mainscreen].bounds];

Activityindicatorview = [[Uiactivityindicatorview alloc]initwithframe:[uiscreen mainscreen].bounds];

[Activityindicatorview SetCenter:opaqueView.center];

[Activityindicatorview Setactivityindicatorviewstyle:uiactivityindicatorviewstylewhite];

[Opaqueview Setbackgroundcolor:[uicolor Blackcolor];

[Opaqueview setalpha:0.6];

[Self.view Addsubview:opaqueview];

[Opaqueview Addsubview:activityindicatorview];

Do any additional setup after loading the view.

}

-(void) Webviewdidstartload: (UIWebView *) webview{

[Activityindicatorview startanimating];

Opaqueview.hidden = NO;

}

-(void) Webviewdidfinishload: (UIWebView *) webview{

[Activityindicatorview startanimating];

Opaqueview.hidden = YES;

}

UIWebView how to determine HTTP 404 and other errors

-(void) connection: (Nsurlconnection *) connection didreceiveresponse: (Nsurlresponse *) response{

Nsurl *url = [Nsurl urlwithstring:@ "http://www.baidu.com"];

Nshttpurlresponse *httpresponse = (Nshttpurlresponse *) response;

if (([httpresponse statuscode]/100) = = 2)) {

Self.earthquakedata = [Nsmutabledata data];

[UIApplication sharedapplication].networkactivityindicatorvisible = YES;

[Web loadrequest:[nsurlrequest Requestwithurl:url];

Web.delegate = self;

} else {

Nsdictionary *userinfo = [Nsdictionary dictionarywithobject:

Nslocalizedstring (@ "HTTP Error",

@ "error message displayed when receving a connection error.")

Forkey:nslocalizeddescriptionkey];

Nserror *error = [Nserror errorwithdomain:@ "HTTP" Code:[httpresponse StatusCode] userinfo:userinfo];

if ([error code] = = 404) {

NSLog (@ "xx");

Web.hidden = YES;

}

}

Do any additional setup after loading the view.

}

-(void) didreceivememorywarning {

[Super didreceivememorywarning];

Dispose of any resources the can be recreated.
