Combine static and prototype content in a table view

问题:

Is there a way to combine static tableview cells (static content) with dynamic tableview cells (prototype content) using storyboard?

回答1:

I suggest you treat your table as dynamic, but include the cells you always want at the top. In the Storyboard, place a UITableViewController and have it use a dynamic table. Add as many UITableViewCell prototypes to the table as you need. Say, one each for your static cells, and one to represent the variable cells.

In your UITableViewDataSource class:

#define NUMBER_OF_STATIC_CELLS  3  - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {     return [self.dynamicModel count] + NUMBER_OF_STATIC_CELLS; } 

and, then

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {      if (indexPath.row

I had a problem, although it was a slight variant of this. I actually wanted to mix dynamic and static cells but in different groups. Meaning group 1 would have static only cells and group 2 would have dynamic cells.

I accomplished this by actually hard coding static cell values (based on their prototype cell identifiers). The dynamic sections would have normal dynamically populated content. Here is some example code in case anyone else has the same issue:

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {         if (section == 1){         return @"Dynamic Cells";     }     if (section == 0){         return @"Static Cells";     } }  - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {     if (section == 0) {         return 1; //However many static cells you want     } else {         return [_yourArray count];     } }  -(UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath {     if (indexPath.section == 0) {         NSString *cellIdentifier = @"staticCellType";            UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];          if (cell == nil) {             cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];         }          cell.textLabel.text = @"some static content";                 return cell;      } else if (indexPath.section == 1){          NSString *cellIdentifier = @"dynamicCellType";         UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];          if (cell == nil) {             cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];         }          cell.textLabel.text = [_yourArray objectAtIndex:indexPath.row];         return cell;      }      return nil;  }  - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {     return 2; }

You can always make one you your tableviews appear similar to the static table but define it in code. Set the sections, amount or rows per section, headers etc. through the delegate methods.

回答4:

Unfortunately, this is not possible since static table views must be in a UITableViewController and that only allows one tableview.

What you need to do is make three more dynamic UITableviewCell's and load them individually for the first three rows where you want the static content.

If you aren't sure how to do this, let me know and I can find some code.

Since no one has actually provided a real answer to the problem (using both static and prototype cells in the same table view), I figured I'd chime in. It can be done!

Create your static cells as you see fit. For the sections that need a dynamic cell, if you are NOT using standard UITableViewCell type, you'll need to create your custom one in a separate Nib, otherwise you can use the standard ones. Then implement the following delegates. Basically for each of these delegates, for the static stuff we want to call super, for the dynamic, we return our values.

First, IF you need to selectively show your dynamic section, you'll want to implement the numberOfSectionsInTableView (otherwise you can leave this delegate out):

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {     int staticSections = 1;     int dynamicSections = 1;     if (SOME_BOOLEAN) {         return staticSections + dynamicSections;     } else {         return staticSections;     } } 

Then, you need to implement numberOfRowsInSection:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {     if (section == 1) {         return A_COUNT;     } else {         return [super tableView:tableView numberOfRowsInSection:section];     } } 

Then, you need to implement heightForRowAtIndexPath:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {     if (indexPath.section == 1) {         return 44.0f;     } else {         return [super tableView:tableView heightForRowAtIndexPath:indexPath];     } } 

Then indentationLevelForRowAtIndexPath:

- (NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath {     if (indexPath.section == 1) {         return 1; // or manually set in IB (Storyboard)     } else {         return [super tableView:tableView indentationLevelForRowAtIndexPath:indexPath]; // or 0     } } 

Finally, cellForRowAtIndexPath:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {     if (indexPath.section == 1) {         SomeObject *obj = self.someArray[indexPath.row];         UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"DynamicCell" forIndexPath:indexPath];         cell.textLabel.text = obj.textValue;         return cell;     } else {         return [super tableView:tableView cellForRowAtIndexPath:indexPath];     } }

You can't have one tableview be static and the other dynamic in the same view controller so you will need to make them both dynamic. In the first tableview you will configure the cells in code on initializing the view controller never update them.

1. Add a UIViewController to your storyboard.
2. Add two Table Views (Not TableViewControllers) to the UIView Controller.
3. Select each tableView and configure both for dynamic cells.
4. Build and attach your view controller. 2 tableview on a single view explains that step.

As another option you can achieve a similar look by embedding your dynamic tableview in part of a view similar to the link in step 4 and then do whatever you wanted to in the rest of the view to setup what you were planning to do with static cells by using scrollviews, labels, and buttons.

回答7:

You could also create buttons (one for each static cell you have) that are styled like your cells and place them in the tableHeaderView or tableFooterView of the UITableView; those buttons are just views after all.

You'll need to add some logic for making selections on the buttons vs. the cells so it maintains the usual look and feel.

Of course, this assumes that you want to insert static cells into your table view at the top or bottom of the table.

One way to have dynamic content in a static table view is to clone cells where additional rows are needed.

For the dynamic section of my table view, I lay out one or more cells in Interface Builder. At runtime, I can clone those by archiving using NSCoder and then unarchiving.

It works, but is not necessarily prettier than starting with a dynamic prototype table view and creating static rows from there.

It fails with standard table view cells. The lazily created text labels are not laid out correctly. Hence I used UITableViewCell subclasses where I take care of archiving and unarchiving subviews.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {     if (indexPath.section == kContactsSection) {         NSArray     *contacts   = self.contacts;         Contact     *contact    = [contacts objectAtIndex:indexPath.row];         NSString    *name       = contact.name;         NSString    *role       = contact.role;          if ([role length] == 0) {             NNContactDefaultTableViewCell *cell = (id)[tableView dequeueReusableCellWithIdentifier : @"contactDefault"];              if (cell == nil) {                 NNContactDefaultTableViewCell   *template   = (id)[super tableView : tableView                                                          cellForRowAtIndexPath :[NSIndexPath indexPathForRow:0 inSection:kContactsSection]];                  NSData                          *data       = [NSKeyedArchiver archivedDataWithRootObject:template];                  cell = [NSKeyedUnarchiver unarchiveObjectWithData:data];             }              cell.contactTextLabel.text = name;              return cell;         }         else {             NNContactDetailTableViewCell *cell = (id)[tableView dequeueReusableCellWithIdentifier : @"contactDetail"];              if (cell == nil) {                 NNContactDetailTableViewCell    *template   = (id)[super tableView : tableView                                                         cellForRowAtIndexPath :[NSIndexPath indexPathForRow:1 inSection:kContactsSection]];                  NSData                          *data       = [NSKeyedArchiver archivedDataWithRootObject:template];                  cell = [NSKeyedUnarchiver unarchiveObjectWithData:data];             }              cell.contactTextLabel.text          = name;             cell.contactDetailTextLabel.text    = role;              return cell;         }     }      return [super tableView:tableView cellForRowAtIndexPath:indexPath]; } 

In the above example I have two cell types. Both laid out in Interface Builder as part of a static table view.

To get dynamic content in one section, I also need to override the following methods:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {     if (section == kContactsSection) {         NSArray     *contacts       = self.contacts;         NSUInteger  contactCount    = [contacts count];          return contactCount;     }      return [super tableView:tableView numberOfRowsInSection:section]; }  - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {     NSInteger   section = indexPath.section;     NSInteger   row     = indexPath.row;      if (section == kContactsSection) {         return [super tableView:tableView heightForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:kContactsSection]];     }      return [super tableView:tableView heightForRowAtIndexPath:indexPath]; }  - (CGFloat)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath {     NSInteger   section     = indexPath.section;      if (section == kContactsSection) {         CGFloat indentation = [super tableView:tableView indentationLevelForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:kContactsSection]];          return indentation;     }      CGFloat     indentation = [super tableView:tableView indentationLevelForRowAtIndexPath:indexPath];      return indentation; }
