-(BaseNavigationController*)setTabBarItemWithRootVC:(id)vc Image:(NSString*)imgName SelectedImage:(NSString*)selectedImg  {      BaseNavigationController *nav = [[BaseNavigationController alloc] init];      [nav.tabBarItem setImage:[[UIImage imageNamed:imgName] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];      [nav.tabBarItem setSelectedImage:[[UIImage imageNamed:selectedImg] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];      [nav.tabBarItem setImage:[[UIImage imageNamed:imgName] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];      [nav.tabBarItem setSelectedImage:[[UIImage imageNamed:selectedImg] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];      returnnav;  }

1.设置按钮操作

//返回按钮  UIBarButtonItem * buttonItem = [[UIBarButtonItem alloc]initWithTitle:nil style:UIBarButtonItemStyleDone target:self action:@selector(backIndex)];      [buttonItem setImage:[UIImage imageNamed:@"返回"]];      self.navigationItem.leftBarButtonItem= buttonItem;    //导航栏标题      self.navigationItem.title = @"个人中心";      [self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName:[XUtil hexToRGB:@"333333"],NSFontAttributeName:[UIFont systemFontOfSize:16]}];          //左键      UIButton *leftBtn = [UIButton buttonWithType:UIButtonTypeCustom];      [leftBtn setImage:[UIImage imageNamed:@"back"] forState:UIControlStateNormal];      [leftBtn addTarget:self action:@selector(backIndex) forControlEvents:UIControlEventTouchUpInside];      UIBarButtonItem *leftItem = [[UIBarButtonItem alloc] initWithCustomView:leftBtn];        self.navigationItem.leftBarButtonItem = leftItem;      //导航栏标题      self.navigationItem.title = @"单词详解";      [self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName:[XUtil hexToRGB:@"2E2F33"],NSFontAttributeName:[UIFont systemFontOfSize:16]}];        //右键      UIButton *moreBtn = [UIButton buttonWithType:UIButtonTypeCustom];      [moreBtn setTitle:@"更多" forState:UIControlStateNormal];      [moreBtn setTitleColor:UIColorFromRGB(0xBDBEBF) forState:UIControlStateNormal];      moreBtn.titleLabel.font = [UIFont systemFontOfSize:12];      [moreBtn addTarget:self action:@selector(quci) forControlEvents:UIControlEventTouchUpInside];      UIBarButtonItem *rightItem = [[UIBarButtonItem alloc] initWithCustomView:moreBtn];      self.navigationItem.rightBarButtonItem = rightItem;    //把view添加到nav  self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:barView];

2.如何找到searchBar中的UItextField并修改

    searchView.frame = CGRectMake(0, kStatusBarHeight + Main_Screen_Width * 10 / 640, Main_Screen_Width * 470 / 640, kTopBarHeight);        searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 284 * adjustWidth, kTopBarHeight)];      //    ViewRadius(searchBar,8.0);      searchBar.delegate = self;      searchBar.barTintColor = [UIColor clearColor];      UITextField* searchTextField = [[[searchBar.subviews firstObject] subviews] lastObject];      searchTextField.dk_textColorPicker = DKColor_TEXTCOLOR_TITLE;      searchTextField.font = font14;      searchBar.searchBarStyle = UISearchBarStyleMinimal;      searchBar.barStyle = UIBarStyleDefault;      [searchBar.layer setBorderWidth:1.0];      searchBar.layer.borderColor = [[UIColor clearColor] CGColor];      searchBar.backgroundColor=[UIColor clearColor];      searchBar.placeholder = @"请输入关键字名称";      [searchView addSubview:searchBar];      [searchBar becomeFirstResponder];      self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:searchView];
