- (void)viewWillAppear:(BOOL)animated { // View defaults to full size. If you want to customize the view's size, or its subviews (e.g. webView), // you can do so here. if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7 && isViewWillAppear == FALSE) { CGRect viewBounds = [self.webView bounds]; viewBounds.origin.y = 20; viewBounds.size.height = viewBounds.size.height - 20; self.webView.frame = viewBounds; NSLog(@"m2 isViewWillAppear == FALSE"); isViewWillAppear = TRUE; } [super viewWillAppear:animated]; }
MainViewController.m 中的 - (void)viewWillAppear:(BOOL)animated 添加以上的代码;
