UIWebView started twice - IOS

Question

I am using the below to add a ProgressView while the UIWebView is loading and dismissing it when it's done. The problem is the UIWebView is started twice and also the ProgressView, So when the page is done loading only one ProgressView is dismissed and the other one doesn't.

ViewController.h

#import <UIKit/UIKit.h>

@interface DirectionViewController : UIViewController <UIWebViewDelegate>
   @property (weak, nonatomic) IBOutlet UIWebView *directionWebView;
@end

ViewController.m

@interface ViewController () 
    @property UIColor *yellowColor;
    @property MRProgressOverlayView *progressView;
@end

@implementation ViewController
- (void)viewDidLoad
{
    [super viewDidLoad];

    self.yellowColor =
    [UIColor colorWithRed:244.0f/255.0f
                    green:208.0f/255.0f
                     blue:63.0f/255.0f
                    alpha:1.0f];
    self.directionWebView.delegate = self;
    NSString *urlMap = [NSString stringWithFormat:@"%@%f,%f&zoom=14", @"http://maps.google.com/maps?q=", self.coordLat, self.coordLong];
    NSURL *url = [NSURL URLWithString:urlMap];
    NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
    [self.directionWebView loadRequest:urlRequest];
}

-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    NSLog(@"WebView start loading...");
    self.progressView = [MRProgressOverlayView new];
    self.progressView.mode = MRProgressOverlayViewModeIndeterminateSmall;
    [self.view.window addSubview:self.progressView];
    [self.progressView setTintColor:self.yellowColor];
    [self.progressView setTitleLabelText:@"Loading ..."];
    [self.progressView show:YES];
    return YES;
}

-(void)webViewDidFinishLoad:(UIWebView *)webView
{
     [self.progressView dismiss:YES];
}
@end

Dont know why it is calling twice but you can do this.

if(!self.progressView){
self.progressView = [MRProgressOverlayView new];
    self.progressView.mode = MRProgressOverlayViewModeIndeterminateSmall;
    [self.view.window addSubview:self.progressView];
    [self.progressView setTintColor:self.yellowColor];
    [self.progressView setTitleLabelText:@"Loading ..."];
    [self.progressView show:YES];
}

-(void)webViewDidFinishLoad:(UIWebView *)webView
{
     [self.progressView dismiss:YES];
self.progressView  = nil;
}
