1 新建一個 controller
2 實現(xiàn) UIWebViewDelegate
3 成員變量 webView activityIndicator
4 根據(jù)自己的 需要 初始化 webView
#import "SecondDetailsViewController.h"
@interface SecondDetailsViewController ()<UIWebViewDelegate>{
UIWebView *webView;
UIActivityIndicatorView *activityIndicator;
}
@end
@implementation SecondDetailsViewController
- (void)viewDidLoad {
[super viewDidLoad];
[self getWebView];
}
- (void)getWebView{
// 協(xié)議
webView.delegate = self;
// 初始化
webView= [[UIWebView alloc] initWithFrame:CGRectMake(0, 150, 320, 150)];
// 請求地址
NSURLRequest *request1 =[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://114.215.108.58/stockInfo.html?code=sh603028"]];
[webView loadRequest:request1];
// 自適應(yīng)
[webView setScalesPageToFit:YES];
[self.view addSubview: webView];
webView.delegate = self;
webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 310, 320, 150)];
NSURLRequest *request2 =[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://114.215.108.58/jscharts.html?code=sh603028"]];
[webView setScalesPageToFit:YES];
[self.view addSubview: webView];
[webView loadRequest:request2];
}
#pragma mark - webView
- (void) webViewDidStartLoad:(UIWebView *)webView
{
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
[view setTag:108];
[view setBackgroundColor:[UIColor blackColor]];
[view setAlpha:0.1];
[self.view addSubview:view];
activityIndicator = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 32.0f, 32.0f)];
[activityIndicator setCenter:view.center];
[activityIndicator setActivityIndicatorViewStyle:UIActivityIndicatorViewStyleWhite];
[view addSubview:activityIndicator];
[activityIndicator startAnimating];
}
- (void) webViewDidFinishLoad:(UIWebView *)webView
{
[activityIndicator stopAnimating];
UIView *view = (UIView*)[self.view viewWithTag:108];
[view removeFromSuperview];
}
- (void) webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
