iOS开发之UITableViewCell的官方文档库
UITableViewCell 继承自UIView，是UITableView的重要组件。
一下是截取的官方文档：
NS_CLASS_AVAILABLE_IOS(2_0) @interface UITableViewCell : UIView <NSCoding, UIGestureRecognizerDelegate>
// Designated initializer. If the cell can be reused, you must pass in a reuse identifier. You should use the same reuse identifier for all cells of the same form.
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier NS_AVAILABLE_IOS(3_0);
// Content. These properties provide direct access to the internal label and image views used by the table view cell. These should be used instead of the content properties below.
@property (nonatomic, readonly, retain) UIImageView *imageView NS_AVAILABLE_IOS(3_0); // default is nil. image view will be created if necessary.
@property (nonatomic, readonly, retain) UILabel *textLabel NS_AVAILABLE_IOS(3_0); // default is nil. label will be created if necessary.
@property (nonatomic, readonly, retain) UILabel *detailTextLabel NS_AVAILABLE_IOS(3_0); // default is nil. label will be created if necessary (and the current style supports a detail label).
// If you want to customize cells by simply adding additional views, you should add them to the content view so they will be positioned appropriately as the cell transitions into and out of editing mode.
@property (nonatomic, readonly, retain) UIView *contentView;
// Default is nil for cells in UITableViewStylePlain, and non-nil for UITableViewStyleGrouped. The 'backgroundView' will be added as a subview behind all other views.
@property (nonatomic, retain) UIView *backgroundView;
// Default is nil for cells in UITableViewStylePlain, and non-nil for UITableViewStyleGrouped. The 'selectedBackgroundView' will be added as a subview directly above the backgroundView if not nil, or behind all other views. It is added as a subview only when the cell is selected. Calling -setSelected:animated: will cause the 'selectedBackgroundView' to animate in and out with an alpha fade.
@property (nonatomic, retain) UIView *selectedBackgroundView;
// If not nil, takes the place of the selectedBackgroundView when using multiple selection.
@property (nonatomic, retain) UIView *multipleSelectionBackgroundView NS_AVAILABLE_IOS(5_0);
@property (nonatomic, readonly, copy) NSString *reuseIdentifier;
- (void)prepareForReuse; // if the cell is reusable (has a reuse identifier), this is called just before the cell is returned from the table view method dequeueReusableCellWithIdentifier:. If you override, you MUST call super.
@property (nonatomic) UITableViewCellSelectionStyle selectionStyle; // default is UITableViewCellSelectionStyleBlue.
@property (nonatomic, getter=isSelected) BOOL selected; // set selected state (title, image, background). default is NO. animated is NO
@property (nonatomic, getter=isHighlighted) BOOL highlighted; // set highlighted state (title, image, background). default is NO. animated is NO
- (void)setSelected:(BOOL)selected animated:(BOOL)animated; // animate between regular and selected state
- (void)setHighlighted:(BOOL)highlighted animated:(BOOL)animated; // animate between regular and highlighted state
@property (nonatomic, readonly) UITableViewCellEditingStyle editingStyle; // default is UITableViewCellEditingStyleNone. This is set by UITableView using the delegate's value for cells who customize their appearance accordingly.
@property (nonatomic) BOOL showsReorderControl; // default is NO
@property (nonatomic) BOOL shouldIndentWhileEditing; // default is YES. This is unrelated to the indentation level below.
@property (nonatomic) UITableViewCellAccessoryType accessoryType; // default is UITableViewCellAccessoryNone. use to set standard type
@property (nonatomic, retain) UIView *accessoryView; // if set, use custom view. ignore accessoryType. tracks if enabled can calls accessory action
@property (nonatomic) UITableViewCellAccessoryType editingAccessoryType; // default is UITableViewCellAccessoryNone. use to set standard type
@property (nonatomic, retain) UIView *editingAccessoryView; // if set, use custom view. ignore editingAccessoryType. tracks if enabled can calls accessory action
@property (nonatomic) NSInteger indentationLevel; // adjust content indent. default is 0
@property (nonatomic) CGFloat indentationWidth; // width for each level. default is 10.0
@property (nonatomic) UIEdgeInsets separatorInset NS_AVAILABLE_IOS(7_0) UI_APPEARANCE_SELECTOR; // allows customization of the separator frame
@property (nonatomic, getter=isEditing) BOOL editing; // show appropriate edit controls (+/- & reorder). By default -setEditing: calls setEditing:animated: with NO for animated.
- (void)setEditing:(BOOL)editing animated:(BOOL)animated;
@property(nonatomic, readonly) BOOL showingDeleteConfirmation; // currently showing "Delete" button
// These methods can be used by subclasses to animate additional changes to the cell when the cell is changing state
// Note that when the cell is swiped, the cell will be transitioned into the UITableViewCellStateShowingDeleteConfirmationMask state,
// but the UITableViewCellStateShowingEditControlMask will not be set.
- (void)willTransitionToState:(UITableViewCellStateMask)state NS_AVAILABLE_IOS(3_0);
- (void)didTransitionToState:(UITableViewCellStateMask)state NS_AVAILABLE_IOS(3_0);
