//进度条

_progressView = [[UIProgressViewalloc] initWithFrame:CGRectMake(0, 62, bgView.bounds.size.width,2)];

_progressView.progressTintColor = [UIColorcolorWithHexString:GrassGreen];

_progressView.trackTintColor = [UIColorcolorWithHexString:GrayLightColor];

[bgView addSubview:_progressView];

//UIWebViewDelegate

-(void)webViewDidStartLoad:(UIWebView *)webView{

_progressView.progress =0;

_isLoadFinish =NO;

_timer = [NSTimerscheduledTimerWithTimeInterval:0.01667target:selfselector:@selector(timerCallback)userInfo:nilrepeats:YES];

}

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

_isLoadFinish =YES;

}

-(void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error{

}

-(void)timerCallback {

if (_isLoadFinish) {

if (_progressView.progress >=1) {

_progressView.hidden =true;

[_timerinvalidate];

}else {

_progressView.progress +=0.1;

}

}else {

_progressView.progress +=0.05;

if (_progressView.progress >=0.95) {

_progressView.progress =0.95;

}

页面消失的时候记得销毁定时器
