loading的两种常用方式
1、
UIActivityIndicatorView *loadingView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
[self.tableView addSubview:loadingView];
[loadingView startAnimating];
// 居中
loadingView.centerX=self.view.centerX;
loadingView.centerY=self.tableView.height*0.4;
self.loadingView = loadingView;
[self.loadingView stopAnimating];
2、
- (void)webViewDidFinishLoad:(UIWebView *)webView {
[MBProgressHUD hideHUDForView:self.view animated:YES];
}
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error {
[MBProgressHUD hideHUDForView:self.view animated:YES];
}
- (void)webViewDidStartLoad:(UIWebView *)webView {
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.mode = MBProgressHUDModeIndeterminate;
hud.labelText = @"Loading...";
}
