IOS UITableView和NavigationBar的常用設置詳解

TableView：

1.tableview常用基本設置

// 清除父類UIEdgeInsets 
self.tableView.contentInset = UIEdgeInsetsMake(0, 0, 0,0); 
//禁止滾動 
self.tableView.scrollEnabled = NO; 
// tableview頭部視圖設置 
self.tableView.tableHeaderView =一個UIView; 
//tableview尾部視圖設置，這樣用一個不占空間的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]; 
//取消垂直滾動條 
self.tableView.showsVerticalScrollIndicator=NO; 
//設置表格背景圖片 
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常用基本設置

//表格附件樣式,指示箭頭 
  
  cell.accessoryType=UITableViewCellAccessoryDisclosureIndicator; 
//禁止點擊變色 
  
  cell.selectionStyle=UITableViewCellSelectionStyleNone; 

3.cell分割線左側空白清除     

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

//分割線清邊界（沒啥變化） 
  if ([cell respondsToSelector:@selector(setLayoutMargins:)]) { 
    [cellsetLayoutMargins:UIEdgeInsetsZero]; 
  } 

//清除父邊界 
  if ([cell respondsToSelector:@selector(setPreservesSuperviewLayoutMargins:)]){ 
    [cellsetPreservesSuperviewLayoutMargins:NO]; 
  
  } 

NavigationBar導航欄:

1.常用基本設置

self.title =@"標題"; 
// 導航欄顏色 
self.navigationBar.barTintColor=[UIColor grayColor]; 
// 導航欄文字顏色 
self.navigationBar.tintColor=[UIColor whiteColor]; 
// 導航欄標題顏色 
NSMutableDictionary*textAttrs= [NSMutableDictionary dictionary]; 
 textAttrs[NSForegroundColorAttributeName] =[UIColor whiteColor]; 
self.navigationBarsetTitleTextAttributes:textAttrs]; 
  
//導航欄按鈕1 
UIBarButtonItem*button1= [[UIBarButtonItem alloc] 
             initWithBarButtonSystemItem:UIBarButtonSystemItemAddtarget:selfaction:@selector(function1)]; 
//導航欄按鈕2 
UIBarButtonItem*button2= [[UIBarButtonItem alloc] 
              initWithBarButtonSystemItem:UIBarButtonSystemItemSearchtarget:selfaction:@selector(function2)]; 
//將按鈕添加到導航欄右側（可以添加多個） 
  
self.navigationItem.rightBarButtonItems=@[button1, button2]; 

2.系統自帶按鈕

枚舉定義及樣式解釋如下：

typedef NS_ENUM(NSInteger, UIBarButtonSystemItem) { 
  UIBarButtonSystemItemDone,   //Done英文字符 
  UIBarButtonSystemItemCancel,  //Cancel 
  UIBarButtonSystemItemEdit,   //Edit 
  UIBarButtonSystemItemSave,   //Save  
  UIBarButtonSystemItemAdd,    //圖標1（加號圖標➕） 
  UIBarButtonSystemItemFlexibleSpace, //？空白 
  UIBarButtonSystemItemFixedSpace,   //？空白 
  UIBarButtonSystemItemCompose,    //圖標2（寫字板上一支筆寫字的圖標） 
  UIBarButtonSystemItemReply,     //圖標3 
  UIBarButtonSystemItemAction,     //圖標4 
  UIBarButtonSystemItemOrganize,    //圖標5 
  UIBarButtonSystemItemBookmarks,   //<span >圖標6</span> 
  UIBarButtonSystemItemSearch,     //<span >圖標7</span> 
  UIBarButtonSystemItemRefresh,    //<span >圖標8</span> 
  UIBarButtonSystemItemStop,      //圖標9 
  UIBarButtonSystemItemCamera,     //圖標10 
  UIBarButtonSystemItemTrash,     //圖標11 
  UIBarButtonSystemItemPlay,      //圖標12 
  UIBarButtonSystemItemPause,     //圖標13 
  UIBarButtonSystemItemRewind,     //圖標14 
  UIBarButtonSystemItemFastForward,  //圖標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 
};
