???UITextAlignmentRight 右对齐

???UITextAlignmentCenter 中对齐

(3) 字体和尺寸:#import <UIKit/UIFont.h>

UIFont *myFont = [ UIFont fontWithName: @"Arial" size: 18.0 ];?

cell.font = myFont;

//系统字体

UIFont *mySystemFont = [ UIFont systemFontOfSize: 12.0 ];

UIFont *myBoldSystemFont = [ UIFont boldSystemFontOfSize: 12.0 ];

UIFont *myItalicSystemFont = [ UIFont italicSystemFontOfSize: 12.0 ];

(4) 颜色

#import <UIKit/UIColor.h>

//文本颜色

cell.textColor = [ UIColor redColor ];

//当前选择项的颜色

cell.selectedTextColor = [ UIColor blueColor ];

(5) 图像

//从你应用程序目录下的文件创建一个image

cell.image = [ UIImage imageNamed: @"cell.png" ];

//当前选中项的图形

cell.selectedImage = [ UIImage imageNamed: @"selected_cell.png" ];

可以修改table保准行高来适应你的图形高度

- (id)init?

{

????self = [ super init ];

????if (self != nil) {

????????self.tableView.rowHeight = 65;?

????}

????return self;?

}

你也可以为每一个cell定义不同的高度

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath?

{

????if ([ indexPath indexAtPosition: 1 ] == 0)

????????return 65.0;?

????else

????????return 40.0;?

}

(6)选中项的风格

cell.selectionStyle?= UITableViewCellSelectionStyleBlue;

UITableViewCellSelectionStyleBlue 默认选中项是蓝色

UITableViewCellSelectionStyleGray 灰色

UITableViewCellSelectionStyleNone?没有变化


(7)标签 (labels)


在偏移量100x0处创建一个尺寸50x50?label:

UILabel *label = [ [ UILabel alloc ] initWithFrame: CGRectMake(100.0, 0.0, 50.0, 50.0) ];

label.text = @"Label Text";

label.textAlignment = UITextAlignmentLeft;

label.textColor = [ UIColor redColor ];

label.font = [ UIFont fontWithName: @"Arial" size: 10.0 ];

标签label可以设置文本阴影,甚至可以定义阴影的偏移:

label.shadowColor = [ UIColor grayColor ];

label.shadowOffset = CGSizeMake(0, -1);

高亮是的颜色:

label.highlightedTextColor = [ UIColor blackColor ];

标签的背景色:

label.backgroundColor = [ UIColor blueColor ];

把标签加到cell里

[ cell addSubview: label ];

(8) 附件

cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;StyleDescriptionUITableViewCellAccessoryNone没有附件UITableViewCellAccessoryDisclosureIndicator黑色向右的箭头UITableViewCellAccessoryDetailDisclosureButton蓝色附件按钮UITableViewCellAccessoryCheckmark复选框,支持选择

?

7.3 实现多选

- (void)tableView:(UITableView *)tableView

????????didSelectRowAtIndexPath:(NSIndexPath *)indexPath?

{

????NSLog(@"Selected section %d, cell %d",?

????????[ indexPath indexAtPosition: 0 ], [ indexPath indexAtPosition: 1 ]);?

????//获的当前选择项

????UITableViewCell *cell = [ self.tableView cellForRowAtIndexPath: indexPath ];?

????//显示复选框

????if (cell.accessoryType == UITableViewCellAccessoryNone)

????????cell.accessoryType = UITableViewCellAccessoryCheckmark;

????else

????????cell.accessoryType = UITableViewCellAccessoryNone;?

}

7.4 编辑和删除

在允许用户删除和编辑的时候,每一个cell左边会显示一个红色删除图标

[ self.tableView setEditing:YES animated:YES ];

关闭编辑的时候,table顶部会显示一个Edit导航条

[ self.tableView setEditing: NO animated: YES ];

在编辑过程中,如果用户要删除该项,会弹出一个删除确认框. 确认后调UITableViewDataSource类的commitEditingStyle方法来通知你的应用程序, 然后你可以从你的底层数据源里删除该项,并通知table view删除该行.

- (void)tableView:(UITableView *)tableView

????commitEditingStyle:(UITableViewCellEditingStyle) editingStyle

????forRowAtIndexPath:(NSIndexPath *) indexPath?

{

????if (editingStyle == UITableViewCellEditingStyleDelete)?

????{

????????NSLog(@"Deleted section %d, cell %d", [ indexPath indexAtPosition: 0 ], [ indexPath indexAtPosition: 1 ]);

????????NSMutableArray *array = [ [ NSMutableArray alloc ] init ];

????????[ array addObject: indexPath ];

????????[ self.tableView deleteRowsAtIndexPaths: array

????????????withRowAnimation: UITableViewRowAnimationFade?

????????];

?????}

}

通过传递一个数组给deleteRowsAtIndexPaths方法, 可以删除一行或多行.

?

withRowAnimation至此下列预定义的删除动画

?

AnimationDescriptionUITableViewRowAnimationFadeCell fades outUITableViewRowAnimationRightCell slides out from rightUITableViewRowAnimationLeftCell slides out from leftUITableViewRowAnimationTopCell slides out to top of adjacent cellUITableViewRowAnimationBottomCell slides out to bottom of adjacent cell

7.5 重新加载表

当你的数据变了的时候,你可以重新加载整个表

[ self.tableView reloadData ];
