UIkit框架之UItableview

1.继承链:UIScrrollView:UIview:UIresponder:NSObject

2.创建实例的时候首先需要确定table的类型

3.一个tableview对象必须要有一个数据源和一个委托对象,所以需要遵守 UITableViewDataSource和 UITableViewDelegate的协议

4.初始化一个tableview对象

- (instancetype)initWithFrame:(CGRect)frame
                        style:(UITableViewStyle)style

5.配置一个table view

    (1)@property(nonatomicreadonlyUITableViewStyle style  :只读,返回table view的style

    (2)- (NSInteger)numberOfRowsInSection:(NSInteger)section  :返回一个特定部分的行数

    (3)@property(nonatomicreadonlyNSInteger numberOfSections  :只读,返回部分的数量

    (4)@property(nonatomicCGFloat rowHeight  :设置行的高度

    (5)@property(nonatomicUITableViewCellSeparatorStyle separatorStyle  :设置表格单元使用的分隔线

    (6)@property(nonatomicstrongUIColor *separatorColor  :设置分隔线的颜色

    (7)@property(nonatomiccopyUIVisualEffect *separatorEffect  :应用在表格分隔线的效果

    (8)@property(nonatomicstrongUIView *backgroundView  :设置表格的背景视图

    (9)@property(nonatomic) UIEdgeInsets separatorInset  :设置线是否占满

    (10)@property(nonatomicBOOL cellLayoutMarginsFollowReadableWidth  :A Boolean value that indicates whether the cell margins are derived from the width of the readable content guide.

6.创建表格视图单元:

    (1)- (void)registerNib:(UINib *)nib
forCellReuseIdentifier:(NSString *)identifier

nib

A nib object that specifies the nib file to use to create the cell.

identifier

The reuse identifier for the cell. This parameter must not be nil and must not be an empty string.

注册一个包含指定标示符TableView的Cell的nib对象

    (2)- (void)registerClass:(Class)cellClass
forCellReuseIdentifier:(NSString *)identifier

cellClass

The class of a cell that you want to use in the table.

identifier

The reuse identifier for the cell. This parameter must not be nil and must not be an empty string.

注册一个类用来创建新的Cell

(3)使用指定的标示符返回可重用的Cell

1 - (id)dequeueReusableCellWithIdentifier:(NSString *)identifier forIndexPath:(NSIndexPath *)indexPath
2 //Available in iOS 6.0 and later.

Apple重要提示:使用这个方法之前必须是使用了registerNib:forCellReuseIdentifier:  或者 registerClass:forCellReuseIdentifier:方法注册了Cell 

(4)使用指定的标示符返回可重用的Cell

1 - (id)dequeueReusableCellWithIdentifier:(NSString *)identifier

7.存取头文件和脚本

forHeaderFooterViewReuseIdentifier:(NSString *)identifier

aClass

The class of a header or footer view that you want to use in the table.

identifier

The reuse identifier for the header or footer view. This parameter must not be nil and must not be an empty string.
