IPhone application development UITableView

IPhoneApplication DevelopmentUITableViewI will introduce the content of this article with little content, mainly based on code implementation.UITableViewLet's look at the content.

-Create UITableView

 
 

  
  
DataTable = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 420)];  
  
  
[DataTable setDelegate:self];  
  
  
[DataTable setDataSource:self];  
  
  
[self.view addSubview:DataTable];  
  
  
[DataTable release]; 
 
 

2. Description of UITableView Methods

 
 

  
  
// Total number of sections
  
  
-(NSArray *) sectionIndexTitlesForTableView :( UITableView *) tableView {
  
  
Return TitleData;
  
  
}
  
  
 
  
  
// Section Titles
  
  
// The title displayed for each section
  
  
-(NSString *) tableView :( UITableView *) tableView titleForHeaderInSection :( NSInteger) section {
  
  
Return @"";
  
  
}
  
  
 
  
  
// Specify the number of partitions. The default value is 1.
  
  
-(NSInteger) numberOfSectionsInTableView :( UITableView *) tableView {
  
  
Return 4;
  
  
}
  
  
 
  
  
// Specify the number of rows in each partition. The default value is 1.
  
  
-(NSInteger) tableView :( UITableView *) tableView numberOfRowsInSection :( NSInteger) section {
  
  
}
  
  
 
  
  
// Draw a Cell
  
  
-(UITableViewCell *) tableView :( UITableView *) tableView cellForRowAtIndexPath :( NSIndexPath *) indexPath {
  
  
Static NSString * SimpleTableIdentifier = @ "SimpleTableIdentifier ";
  
  

  
  
UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:
  
  
SimpleTableIdentifier];
  
  
If (cell = nil ){
  
  
Cell = [[[UITableViewCell alloc] initWithStyle: UITableViewCellStyleDefault
  
  
ReuseIdentifier: SimpleTableIdentifier] autoreler];
  
  
}
  
  
Cell. imageView. image = image; // The image when no cell is selected
  
  
Cell. imageView. highlightedImage = highlightImage; // The image after the cell is selected
  
  
Cell. text = //.....
  
  
Return cell;
  
  
}
  
  
 
  
  
// Line indent
  
  
-(NSInteger) tableView :( UITableView *) tableView indentationLevelForRowAtIndexPath :( NSIndexPath *) indexPath {
  
  
NSUInteger row = [indexPath row];
  
  
Return row;
  
  
}
  
  
 
  
  
// Change the Row Height
  
  
-(CGFloat) tableView :( UITableView *) tableView heightForRowAtIndexPath :( NSIndexPath *) indexPath {
  
  
Return 40;
  
  
}
  
  
 
  
  
// Locate
  
  
[TopicsTable setContentOffset: CGPointMake (0, promiseNum * 44 + Chapter * 20)];
  
  
 
  
  
// Return the selected cell
  
  
NSIndexPath * ip = [NSIndexPath indexPathForRow: row inSection: section];
  
  
[TopicsTable selectRowAtIndexPath: ip animated: YES scrollPosition: UITableViewScrollPositionNone];
  
  
 
  
  
[TableView setSeparatorStyle: UITableViewCellSelectionStyleNone];
  
  
 
  
  
// Select the Cell to respond to the event
  
  
-(Void) tableView :( UITableView *) tableView didSelectRowAtIndexPath :( NSIndexPath *) indexPath {
  
  
 
  
  
[TableView deselectRowAtIndexPath: indexPath animated: YES]; // The selected reversed color disappears immediately.
  
  
}
  
  
 
  
  
// Determine the selected row to prevent the first row from being selected)
  
  
-(NSIndexPath *) tableView :( UITableView *) tableView willSelectRowAtIndexPath :( NSIndexPath *) indexPath
  
  
{
  
  
NSUInteger row = [indexPath row];
  
  
If (row = 0)
  
  
Return nil;
  
  

  
  
Return indexPath;
  
  
}
  
  
 
  
  
// Indicates whether the del button is displayed on the cell.
  
  
-(BOOL) tableView :( UITableView *) tableView canEditRowAtIndexPath :( NSIndexPath *) indexPath {
  
  
}
  
  
 
  
  
// Edit the status
  
  
-(Void) tableView :( UITableView *) tableView commitEditingStyle :( UITableViewCellEditingStyle) editingStyle
  
  
ForRowAtIndexPath :( NSIndexPath *) indexPath
  
  
{
  
  
}
  
  
 
  
  
[TopicsTable setContentSize: CGSizeMake (0, controller. promiseNum * 44)];
  
  
// Add an index table to the right
  
  
-(NSArray *) sectionIndexTitlesForTableView :( UITableView *) tableView {
  
  
}
  
  
 
  
  
// Return the Section title.
  
  
-(NSString *) tableView :( UITableView *) tableView titleForHeaderInSection :( NSInteger) section {
  
  
}
  
  
 
  
  
// Del button content during custom stroke
  
  
-(NSString *) tableView :( UITableView *) tableView
  
  
TitleForDeleteConfirmationButtonForRowAtIndexPath :( NSIndexPath *) indexPath
  
  
// Jump to the specified row or section
  
  
[TableView scrollToRowAtIndexPath: [NSIndexPath indexPathForRow: 0 inSection: 0] atScrollPosition: UITableViewScrollPositionBottom animated: NO];
  
  
 
  
  
3. Create UILable multi-line display on UITableViewCell
  
  
 
  
  
-(UITableViewCell *) tableView :( UITableView *) tableView cellForRowAtIndexPath :( NSIndexPath *) indexPath {
  
  
Static NSString * CellIdentifier = @ "Cell ";
  
  
UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier: CellIdentifier];
  
  
If (cell = nil ){
  
  
Cell = [[[UITableViewCell alloc] initWithFrame: CGRectZero reuseIdentifier: CellIdentifier] autorelease];
  
  
UILabel * Datalabel = [[UILabel alloc] initWithFrame: CGRectMake (10, 0,320, 44)];
  
  
[Datalabel settag: 100];
  
  
Datalabel. autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
  
  
[Cell. contentView addSubview: Datalabel];
  
  
[Datalabel release];
  
  
}
  
  
UILabel * Datalabel = (UILabel *) [cell. contentView viewWithTag: 100];
  
  
[Datalabel setFont: [UIFont boldSystemFontOfSize: 18];
  
  
Datalabel. text = [data. DataArray objectAtIndex: indexPath. row];
  
  
Cell. accessoryType = UITableViewCellAccessoryDisclosureIndicator;
  
  
Return cell;
  
  
}
  
  
 
  
  
// Select the cell color
  
  
 
  
  
Typedef enum {
  
  
UITableViewCellSelectionStyleNone,
  
  
UITableViewCellSelectionStyleBlue,
  
  
UITableViewCellSelectionStyleGray
  
  
} UITableViewCellSelectionStyle
  
  
 
  
  
// Cell button format on the right
  
  
 
  
  
Typedef enum {
  
  
UITableViewCellAccessoryNone, // don't show any accessory view
  
  
UITableViewCellAccessoryDisclosureIndicator, // regular chevron. doesn't track
  
  
UITableViewCellAccessoryDetailDisclosureButton, // blue button w/chevron. tracks
  
  
UITableViewCellAccessoryCheckmark // checkmark. doesn' t track
  
  
} UITableViewCellAccessoryType
  
  
// Whether to add a line break
  
  
 
  
  
Typedef enum {
  
  
UITableViewCellSeparatorStyleNone,
  
  
UITableViewCellSeparatorStyleSingleLine
  
  
} UITableViewCellSeparatorStyle // change the line feed color
  
  
 
  
  
TableView. separatorColor = [UIColor blueColor];
