现在在接触iOS开发，今天在调试一个界面加载web页面的问题，发现死活无法加载，浏览器里能正常打开，加上相应代码之后得到了错误信息为：
2013-04-18 15:05:06.446 Client_DEMO[22889:1a303] webview didFailLoadWithError <UIWebView: 0x18ff2160; frame = (18 70; 315 408); autoresize = W+H; layer = <CALayer: 0xc1140a0>> , and err is Error Domain=WebKitErrorDomain Code=101 “The operation couldn’t be completed. (WebKitErrorDomain error 101.)”
加日志的办法为：
WebviewDelegat.h 代码如下：
#import <UIKit/UIKit.h>
@interface WebviewDelegate : NSObject <UIWebViewDelegate>
@end
WebviewDelegat.mm 代码如下：
#import “WebviewDelegate.h”
@implementation WebviewDelegate
-(BOOL)webView:(UIWebView *)webView
shouldStartLoadWithRequest:(NSURLRequest *)request
navigationType:(UIWebViewNavigationType)navigationType{
NSString * str =
[[request URL] absoluteString];
NSString *urlStr = [str
stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSArray * strArray = [urlStr
componentsSeparatedByString:@":"];
if([strArray
count]>2)
{
NSLog(@”webview for %@”,urlStr);
if ([[strArray
objectAtIndex:0] isEqualToString:@”jscall”] ) {
//这里拦截做些本地的事情
}
return
NO;
}else{
return YES;
}
}
- (void)webViewDidStartLoad:(UIWebView *)webView{
NSLog(@”webview
webViewDidStartLoad %@”,webView.debugDescription);
}
-
(void)webViewDidFinishLoad:(UIWebView *)webView{
NSLog(@”webview
webViewDidFinishLoad %@”,webView.debugDescription);
}
-
(void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error{
//把出错信息打出来
NSLog(@”webview didFailLoadWithError %@ , and err is
%@”,webView.debugDescription, error.debugDescription);
}
@end
通过UIWebView的setDelegate方法将其绑定。
网上搜索之后得知是urlencode有问题，仔细核实了一下url，发现url里有个参数值有竖线，于是知道了是竖线未转义导致。
比如： http://lizongbo.com/?chid=0|0|618119, 应该为：http://lizongbo.com/?chid=0%7C0%7C618119
解决办法很简单，对url的字符串做了个替换：
sUrl=replaceStr(sUrl,”|”,”%7C”);//不转义的话会报错,nd err is Error Domain=WebKitErrorDomain Code=101 “The operation couldn’t be completed. (WebKitErrorDomain error 101.)”
