启动其他应用的activity，只需要两个东西。该应用的包名，被启动的activity的class全名。两个都是String类型。参考android文档：
Intent android.content.Intent.setClassName(String packageName, String className)
还需一点：被启动的activity需设置标签：
android:exported="true"
这样就够了！
1、确定tableview中分分区数
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 2;
}
2、确定每个section中的cell数量
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
switch (section) {
case 0:
return 1;
break;
case 1 :
return 1;
break;
default:
break;
}
return 1;
}
3、确定Cell中的内容
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
// Configure the cell...
switch (indexPath.section) {//哪一个分区
case 0:
switch (indexPath.row) {//分区中的哪一行
case 0:
cell.textLabel.text=@"1";
break;
default:
break;
}
break;
case 1:
switch (indexPath.row) {//分区中的哪一行
case 0:
cell.textLabel.text=@"66";
break;
default:
break;
}
break;
default:
break;
}
break;
default:
break;
}
return cell;
}
4、点击cell时
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
}

在你的自定义的tableviewcell的m文件里加入下面方法：
重写了tableviewcell的layoutSubviews的方法，调整一下backgroundview和contentview的frame就行了。
NSString *CellIdentifier = [ [ NSString alloc ] initWithString: @"Frank" ];
UITableViewCell *cell = [ [ [ UITableViewCell alloc ]
initWithFrame: CGRectZero
reuseIdentifier: CellIdentifier
] autorelease
];
然后你可以为每一个cell设置不同的风格
(1) 显示文本: cell.text = @"Frank's Table Cell";
(2) 对齐: cell.textAlignment = UITextAlignmentLeft;UITextAlignmentLeft 默认是左对齐
UITextAlignmentRight 右对齐
UITextAlignmentCenter 中对齐
(3) 字体和尺寸: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; Style Description UITableViewCellAccessoryNone 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
Animation Description UITableViewRowAnimationFade Cell fades out UITableViewRowAnimationRight Cell slides out from right UITableViewRowAnimationLeft Cell slides out from left UITableViewRowAnimationTop Cell slides out to top of adjacent cell UITableViewRowAnimationBottom Cell 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 ];
