<a id="one">一、表視圖的組成 </a>
- 表頭視圖（table header view） 表示圖最上邊
- 表腳視圖（table footer view） 表示圖最下邊
- 單元格 （cell） 組成表示圖每一行的單位視圖
- 節（section） 有多個單元格組成，有節頭（左對齊）和節腳（左對齊），一般節頭描述節的信息，節腳描述節的信息和聲明
<a id="two"> 二、表視圖類型</a>
UITableView 創建時
- initWithFrame:(CGRect) style:(UITableViewStyle)
UITableViewController 創建時
- initWithStyle:(UITableViewStyle)
UITableViewStyle 有兩種樣式
- UITableViewStylePlain 普通表視圖，一般用于動態表，單元格數目未知
- UITableViewStyleGrouped 分組表視圖，一般用于靜態表，以孤島進行界面布局，同時也用于控件的界面布局
<a name="three">三、cell 的相關樣式</a>
一般通過以下方式創建
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *cellIdentifier = @"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
NSInteger row = [indexPath row];
cell.textLabel.text = self.listData[row];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
cell類型
- UITableViewCellStyleDefault 默認樣式，只有圖標和主標題
- UITableViewCellStyleSubtitle Subtitle樣式，圖標、主標題、副標題（位于主標題下方）
- UITableViewCellStyleValue1 Value1樣式，主標題和副標題，主標題左對齊，副標題右對齊，圖標可有可無
- UITableViewCellStyleValue2 Value2樣式，主標題和副標題，兩者居中對齊，無圖標
cell擴展視圖類型
cell.accessoryType = UITableViewCellAccessoryType；
- UITableViewCellAccessoryNone 沒有擴展圖標
- UITableViewCellAccessoryDisclosureIndicator 擴展指示器，觸摸該圖標將切換到下一級表視圖，圖標為">"
- UITableViewCellAccessoryDetailDisclosureButton 細節展示按鈕，觸摸該單元格時，表視圖會以視圖的方式顯示當前單元格的更多詳細信息，圖標為“?”
- UITableViewCellAccessoryCheckmark 選中標志，表示該行被選中，圖標為“??”
<a name="four">四、數據源協議 UITableViewDataSource</a>
//為表視圖單元格提供數據，必須實現
@protocol UITableViewDataSource<NSObject>
@required
//返回某個節點中的行數
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;

@optional
//返回節的個數
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView;
//返回節頭標題
- (nullable NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section;
//返回節腳標題
- (nullable NSString *)tableView:(UITableView *)tableView titleForFooterInSection:(NSInteger)section;
//Individual rows can opt out of having the -editing property set for them. If not implemented, all rows are assumed to be editable.
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath;
