地图未显示在网络视图中 - iOS

Question

我的视图中有一个按钮。单击它会导致我想在其中显示地图的网络视图。我使用的代码是：

- (void)viewWillAppear:(BOOL)animated{
    NSString *url =  [@"http://maps.apple.com/?q=" stringByAppendingString:self.address];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
    NSURLRequest *metricsRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:url]];
    _webViewForLocation.delegate = self;
    [_webViewForLocation loadRequest:metricsRequest];
    NSLog(@"Maps String: %@", url);
}

但是网络视图是空白的。如何在其中显示地图？

Answer 1

尝试

- (void)viewDidLoad
{
[super viewDidLoad];

[_webViewForLocation loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://maps.google.com/?q=bangalore"]]]];  // here pass your string


- (void)webViewDidStartLoad:(UIWebView *)webView
{
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;

}
- (void)webViewDidFinishLoad:(UIWebView *)webView
{

 }



- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
}

输出是
