IOS UITableView和NavigationBar的常用设置详解

TableView：

1.tableview常用基本设置

// 清除父类UIEdgeInsets
self.tableView.contentInset = UIEdgeInsetsMake(0, 0, 0,0);
//禁止滚动
self.tableView.scrollEnabled = NO;
// tableview头部视图设置
self.tableView.tableHeaderView =一个UIView;
//tableview尾部视图设置，这样用一个不占空间的UIView初始化可以清除尾部多余空格
self.tableView.tableFooterView = [[UIView alloc]initWithFrame:CGRectZero];
//表格背景色
self.tableView.backgroundColor = [UIColorgrayColor];
//取消垂直滚动条
self.tableView.showsVerticalScrollIndicator=NO;
//设置表格背景图片
UIView *bgView= [[UIView alloc]initWithFrame:CGRectMake(0,20,SLApplicationW,SLApplicationH)];
UIImageView *bgImageView= [[UIImageView alloc]initWithFrame:CGRectMake(0,0,SLApplicationW,SLApplicationH)];
  [bgImageView setImage:[UIImageimageNamed:@"tree"]];
  [bgView addSubview:bgImageView];
self.tableView.backgroundView= bgView;

2.cell常用基本设置

//表格附件样式,指示箭头 

  cell.accessoryType=UITableViewCellAccessoryDisclosureIndicator;
//禁止点击变色 

  cell.selectionStyle=UITableViewCellSelectionStyleNone;

3.cell分割线左侧空白清除

//分割线清偏移
  if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
    [cellsetSeparatorInset:UIEdgeInsetsZero];
  } 

//分割线清边界（没啥变化）
  if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
    [cellsetLayoutMargins:UIEdgeInsetsZero];
  }

//清除父边界
  if ([cell respondsToSelector:@selector(setPreservesSuperviewLayoutMargins:)]){
    [cellsetPreservesSuperviewLayoutMargins:NO]; 

  }

NavigationBar导航栏:

1.常用基本设置

self.title =@"标题";
// 导航栏颜色
self.navigationBar.barTintColor=[UIColor grayColor];
// 导航栏文字颜色
self.navigationBar.tintColor=[UIColor whiteColor];
// 导航栏标题颜色
NSMutableDictionary*textAttrs= [NSMutableDictionary dictionary];
 textAttrs[NSForegroundColorAttributeName] =[UIColor whiteColor];
self.navigationBarsetTitleTextAttributes:textAttrs]; 

//导航栏按钮1
UIBarButtonItem*button1= [[UIBarButtonItem alloc]
             initWithBarButtonSystemItem:UIBarButtonSystemItemAddtarget:selfaction:@selector(function1)];
//导航栏按钮2
UIBarButtonItem*button2= [[UIBarButtonItem alloc]
              initWithBarButtonSystemItem:UIBarButtonSystemItemSearchtarget:selfaction:@selector(function2)];
//将按钮添加到导航栏右侧（可以添加多个） 

self.navigationItem.rightBarButtonItems=@[button1, button2]; 

2.系统自带按钮

枚举定义及样式解释如下：

typedef NS_ENUM(NSInteger, UIBarButtonSystemItem) {
  UIBarButtonSystemItemDone,   //Done英文字符
  UIBarButtonSystemItemCancel,  //Cancel
  UIBarButtonSystemItemEdit,   //Edit
  UIBarButtonSystemItemSave,   //Save
  UIBarButtonSystemItemAdd,    //图标1（加号图标➕）
  UIBarButtonSystemItemFlexibleSpace, //？空白
  UIBarButtonSystemItemFixedSpace,   //？空白
  UIBarButtonSystemItemCompose,    //图标2（写字板上一支笔写字的图标）
  UIBarButtonSystemItemReply,     //图标3
  UIBarButtonSystemItemAction,     //图标4
  UIBarButtonSystemItemOrganize,    //图标5
  UIBarButtonSystemItemBookmarks,   //<span style="font-family: Menlo;">图标6</span>
  UIBarButtonSystemItemSearch,     //<span style="font-family: Menlo;">图标7</span>
  UIBarButtonSystemItemRefresh,    //<span style="font-family: Menlo;">图标8</span>
  UIBarButtonSystemItemStop,      //图标9
  UIBarButtonSystemItemCamera,     //图标10
  UIBarButtonSystemItemTrash,     //图标11
  UIBarButtonSystemItemPlay,      //图标12
  UIBarButtonSystemItemPause,     //图标13
  UIBarButtonSystemItemRewind,     //图标14
  UIBarButtonSystemItemFastForward,  //图标15
  UIBarButtonSystemItemUndo NS_ENUM_AVAILABLE_IOS(3_0),    //Redo
  UIBarButtonSystemItemRedo NS_ENUM_AVAILABLE_IOS(3_0),    //Undo
  UIBarButtonSystemItemPageCurl NS_ENUM_AVAILABLE_IOS(4_0),  //?空白
};
