UIWebView 相应本地事件

概述Objective-c代码   - (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {           AppDelegate *appDelegate=(   Ap Objective-c代码 -(BOol)webVIEw:(UIWebVIEw*)webVIEwshouldStartLoaDWithRequest:(NSURLRequest*)requestnavigationType:(UIWebVIEwNavigationType)navigationType{ AppDelegate*appDelegate=( AppDelegate*)[[UIApplicationsharedApplication]delegate]; if(navigationType==UIWebVIEwNavigationTypelinkClicked){ NSURL*URL=[requestURL]; NSLog([URLscheme]); NSLog([URLabsoluteString]); //codehereandcallthedelegatemethod NSautoreleasePool*pool=[[NSautoreleasePoolalloc]init]; BOolaudioResult=FALSE; NSfileManager*fileManager=[NSfileManagerdefaultManager]; //checkiffileexistedincachefolder NSArray*cache=NSSearchPathForDirectorIEsInDomains(NSCachesDirectory,NSUserDomainMask,YES); Nsstring*cachePath=[cacheobjectAtIndex:0]; Nsstring*filepath; filepath=[cachePathstringByAppendingPathComponent:[audioIDstringByAppendingString:@".wav"]]; if([fileManagerfileExistsAtPath:filepath]==YES){ [selfplayVoice:filepath]; } else { audioResult=[appDelegatesaveAudio:audioID]; if(audioResult==YES) //NSLog(@"Speaktheaudiobythepath=%@",filepath); [poolrelease]; [appDelegatesaveAudio:gotFM]; }

保存声音的方法：
-(BOol)saveAudio:(Nsstring*)key NSLog(key); BOolsaveSuccess=FALSE; Nsstring*dbPath=[[[NSBundlemainBundle]resourcePath]stringByAppendingPathComponent:@"testVoice.db"]; if(sqlite3_open([dbPathUTF8String],&database_voice)==sqlITE_OK) Nsstring*sqlString=[NsstringstringWithFormat:@"select*fromtb_voicewhereID='%@'",key]; NSLog(sqlString); constchar*sql_char=[sqlStringUTF8String]; //preparetheselectstatement intreturnValue=sqlite3_prepare_v2(database_voice,sql_char,-1,&selectStatement,NulL); if(returnValue==sqlITE_OK) //loopalltherowsreturnedbythequery. if(sqlite3_step(selectStatement)==sqlITE_ROW) Nsstring*filename=[NsstringstringWithUTF8String:(char*)sqlite3_column_text(selectStatement,0)]; ////NSLog(filename); NSData*fileData=[NSDatadataWithBytes:sqlite3_column_blob(selectStatement,0)">2)length:sqlite3_column_bytes(selectStatement,0)">2)]; //savethefiledata //check Nsstring*filepath=[cachePathstringByAppendingPathComponent:filename]; filepath=[filepathstringByAppendingString:@".wav"]; if([fileManagercreateDirectoryAtPath:cachePathattributes:nil]==NO){ ////NSLog(@"fileManagercreateDirectoryAtPath:cachePathattributes:nil"); if([fileDatawritetofile:filepathatomically:YES]){ saveSuccess=TRUE; //NSLog(@"saveSuccess"); ////NSLog(@"returnValue"); //NSLog(@"saveFail"); sqlite3_finalize(selectStatement); returnsaveSuccess; } 总结
