使用IBAction从按钮重新加载UIWebView

Question

我正在创建一个使用UIWebView显示计划的应用。我添加了一个按钮，单击该按钮可从Web服务器下载更新的计划。我的尝试是当使用[iPadscheduleView reload]时，使该按钮的动作也刷新UIWebView;它没有任何效果。

我的viewDidLoad

-(void)viewDidLoad {


NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                     NSUserDomainMask,
                                                     YES);

NSString *fullPath = [[paths lastObject] stringByAppendingPathComponent:@"schedule.html"]; 
NSURL *url = [NSURL fileURLWithPath:fullPath];
[iPadscheduleView loadRequest:[NSURLRequest requestWithURL: url]];
[super viewDidLoad];
}

我的IBAction按钮

-(IBAction)synctheschedule {
 NSData *fetchedData = [NSData dataWithContentsOfURL:[NSURL  URLWithString:@"http://www.elitespark.com/schedule.html"]];
NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *filePath = [documentsPath stringByAppendingPathComponent:@"schedule.html"];
[fetchedData writeToFile:filePath atomically:YES];

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Popup" message:@"The schedule has been synced with the server." delegate:nil cancelButtonTitle:@"Refresh" otherButtonTitles:nil];
[alert show];
[alert release];    
[iPadscheduleView reload];
}

非常感谢任何帮助。感谢
