UITableView是集成UIScrollView的可以實現(xiàn)滾動查看內(nèi)容

1.1 UITableView的基本方法和屬性

　　選中的行號

- (NSIndexPath *)indexPathForSelectedRow; // returns nil or index path representing section and row of selection.

?　表格編輯模式設(shè)置

// Editing. When set, rows show insert/delete/reorder controls based on data source queries@property (nonatomic, getter=isEditing) BOOL editing; // default is NO. setting is not animated. - (void)setEditing:(BOOL)editing animated:(BOOL)animated;

?　表格cell的分割線設(shè)置,但是一般不符合我們的要求

@property (nonatomic) UITableViewCellSeparatorStyle separatorStyle; // default is UITableViewCellSeparatorStyleSingleLine

?

1.2 UITableDataSource的基本方法和屬性

　　表格顯示數(shù)據(jù)的三個方法

@required- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;// Row display. Implementers should *always* try to reuse cells by setting each cell's reuseIdentifier and querying for available reusable cells with dequeueReusableCellWithIdentifier: // Cell gets various attributes set automatically based on table (separators) and data source (accessory views, editing controls)- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;@optional- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView; // Default is 1 if not implemented

?　　顯示表格組標題

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section; // fixed font style. use custom view (UILabel) if you want something different - (NSString *)tableView:(UITableView *)tableView titleForFooterInSection:(NSInteger)section;

?　　表格組標題索引

// Index- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView; // return list of section titles to display in section index view (e.g. "ABCD...Z#") - (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index; // tell table which section corresponds to section title/index (e.g. "B",1))

　　表格自帶的刪除、添加,詳細見UITableViewCell的滑動刪除隨筆

// Data manipulation - insert and delete support// After a row has the minus or plus button invoked (based on the UITableViewCellEditingStyle for the cell), the dataSource must commit the change // Not called for edit actions using UITableViewRowAction - the action's handler will be invoked instead - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath;

?

1.3?UITableViewDelegate方法

　　實現(xiàn)自定義組頭和組尾視圖,需實現(xiàn)下面2個方法,返回的UIView為自定義View并需要繼承UITableViewHeaderFooterView

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section; // custom view for header. will be adjusted to default or specified header height - (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section; // custom view for footer. will be adjusted to default or specified footer height

?　　設(shè)置行高,組高

// Variable height support- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath; - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section; - (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section;

?　　行選中方法

// Selection// -tableView:shouldHighlightRowAtIndexPath: is called when a touch comes down on a row. // Returning NO to that message halts the selection process and does not cause the currently selected row to lose its selected look while the touch is down. - (BOOL)tableView:(UITableView *)tableView shouldHighlightRowAtIndexPath:(NSIndexPath *)indexPath NS_AVAILABLE_IOS(6_0); - (void)tableView:(UITableView *)tableView didHighlightRowAtIndexPath:(NSIndexPath *)indexPath NS_AVAILABLE_IOS(6_0); - (void)tableView:(UITableView *)tableView didUnhighlightRowAtIndexPath:(NSIndexPath *)indexPath NS_AVAILABLE_IOS(6_0);// Called before the user changes the selection. Return a new indexPath, or nil, to change the proposed selection. - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath; - (NSIndexPath *)tableView:(UITableView *)tableView willDeselectRowAtIndexPath:(NSIndexPath *)indexPath NS_AVAILABLE_IOS(3_0); // Called after the user changes the selection. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath; - (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath NS_AVAILABLE_IOS(3_0);

?　行編輯

// Editing// Allows customization of the editingStyle for a particular cell located at 'indexPath'. If not implemented, all editable cells will have UITableViewCellEditingStyleDelete set for them when the table has editing property set to YES. - (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath; - (NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath NS_AVAILABLE_IOS(3_0); - (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath NS_AVAILABLE_IOS(8_0); // supercedes -tableView:titleForDeleteConfirmationButtonForRowAtIndexPath: if return value is non-nil// Controls whether the background is indented while editing. If not implemented, the default is YES. This is unrelated to the indentation level below. This method only applies to grouped style table views. - (BOOL)tableView:(UITableView *)tableView shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath;// The willBegin/didEnd methods are called whenever the 'editing' property is automatically changed by the table (allowing insert/delete/move). This is done by a swipe activating a single row - (void)tableView:(UITableView*)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath; - (void)tableView:(UITableView*)tableView didEndEditingRowAtIndexPath:(NSIndexPath *)indexPath;
