-(bool) webview:(uiwebview *)webview shouldstartloadwithrequest:(nsurlrequest *)request navigationtype:(uiwebviewnavigationtype)navigationtype { savedlink = [request url]; if ( ( [ [ savedlink scheme ] isequaltostring: @"http" ] || [ [ savedlink scheme ] isequaltostring: @"https" ]) && ( navigationtype == uiwebviewnavigationtypelinkclicked ) ) { uialertview *leaveapp = [[uialertview alloc]initwithtitle:@"warning!" message:@"you want leave app?" delegate:self cancelbuttontitle:@"no" otherbuttontitles:@"yes", nil]; [leaveapp show]; homecoming no; } homecoming yes; } - (void)alertview:(uialertview *)alertview clickedbuttonatindex:(nsinteger)buttonindex { nsstring *title = [alertview buttontitleatindex:buttonindex]; if([title isequaltostring:@"yes"]) { [[uiapplication sharedapplication] openurl:savedlink]; } else if([title isequaltostring:@"no"]) { //do nil } }
