Issue Displaying Multiple Beacons in TableView - ios

I am trying to display multiple beacons in a tableView. The minor values, name, and images for each beacon are stored in core data. While the name and image of the beacon are appearing in the tableView cell correctly, the proximity always changing to the closest beacon.
I really appreciate the help!
DisplayTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"CellID"];
Tag *tag = [self.tags objectAtIndex:indexPath.row];
cell.textLabel.text = #"";
NSData *data = tag.image;
UIImage *image = [UIImage imageWithData:data];
cell.imageView.image = image; //BEACONS
if (self.tags.count > 0)
{
self.arrow.hidden = true;
self.addLabel.hidden = true;
CLBeacon *beacon = [self.beacons objectAtIndex:indexPath.row];
NSString *proximityLabel = #"";
switch (beacon.proximity)
{
case CLProximityFar:
proximityLabel = [NSString stringWithFormat:#"Your %# is Far", tag.name];
cell.backgroundColor = [UIColor colorWithRed:(255/255.0) green:(107/255.0) blue:(105/255.0) alpha:1];
break;
case CLProximityNear:
proximityLabel = [NSString stringWithFormat:#"Your %# is Near", tag.name];
cell.backgroundColor = [UIColor colorWithRed:(96/255.0) green:(102/255.0) blue:(232/255.0) alpha:1];
break;
case CLProximityImmediate:
proximityLabel = [NSString stringWithFormat:#"Your %# is Close", tag.name];
cell.backgroundColor = [UIColor colorWithRed:(118/255.0) green:(225/255.0) blue:(167/255.0) alpha:1];
break;
case CLProximityUnknown:
proximityLabel = #"Fetching Location";
cell.backgroundColor = [UIColor whiteColor];
break;
}
cell.nameLabel.text = tag.name;
NSString *detailLabel = [NSString stringWithFormat:#"%#, Dist: %0.001f", proximityLabel, beacon.accuracy];
cell.proxLabel.text = detailLabel;
self.tableView.hidden = false;
self.mapView.hidden = false;
}
return cell;

I suggest you watch Session 211 of WWDC 2012, Building Concurrent User Interfaces and apply the concepts there. This features cells whose contents are independently queried and rendered.
The basic concept is as follows:
1. In tableView:cellForRowAtIndexPath, a cell is instantiated.
2. In the same method, an operation for retrieving the data to populate the cell is created and stored into a dictionary. A reference to the cell is passed to the operation. The operation has a completion handler that populates the cell and removes the operation from the dictionary.
3. Before the cell is returned from the method, the operation is added to an operation queue.
4. In tableView:didEndDisplayingCell:forRowAtIndexPath, operations for cells that have moved off-screen are cancelled and removed from the dictionary.

two custom cells in a UITableView

I am trying to use two custom cells inside a UITableView. The problem I am running into is that my return is not being called in the right place. I am not sure what I need to implement the return to stop the control from reaching the end of a non-void function.
Here is the code inside my cellforrowatindex.
static NSString *kCellID = #"MessageCell";
static NSString *UCellID = #"UnreadCell";
if (status == 0)
{
//static NSString *kCellID = #"MessageCell";
MessageListCell *cell = (MessageListCell *) [tableView dequeueReusableCellWithIdentifier:kCellID];
if (priority == 0)
{
cell. imageviewImportance.image = nil;
}
if (priority == 1)
{
cell.imageviewImportance.image = [UIImage imageNamed:#"single exclamation.png"];
}
if (priority == 2)
{
cell.imageviewImportance.image = [UIImage imageNamed:#"double exclamation mark.png"];
}
if (priority == 3)
{
cell.imageviewImportance.image = [UIImage imageNamed:#"triple exclamation kmar.png"];
}
//if (status == 0)
//{
cell.backgroundColor = [UIColor clearColor];
cell.labelFrom.text = [NSString stringWithFormat:#"From: %#",m.From];
cell.labelFrom.font = [UIFont boldSystemFontOfSize:17];
cell.labelSubject.text = subject;
cell.labelSubject.font = [UIFont boldSystemFontOfSize:17];
cell.labelTime.text = time;
cell.labelTo.text = [NSString stringWithFormat:#"To: %#",m.To];
cell.labelTo.font = [UIFont boldSystemFontOfSize:17];
return cell;
}
else if (status != 0)
{
//static NSString *UCellID = #"UnreadCell";
MessageListCell *cell = (MessageListCell *)[tableView dequeueReusableCellWithIdentifier:UCellID];
cell.backgroundColor = [UIColor clearColor];
cell.unreadLabelFrom.text = [NSString stringWithFormat:#"From: %#",m.From];
cell.unreadLabelSubject.text = subject;
cell.unreadLabelTo.text = [NSString stringWithFormat:#"To:%#",m.To];
cell.unreadLabelTime.text = time;
return cell;
}
//NSLog(#"description = %#",[cell description]);
//return cell;
}
Simply change the else if to else, then the compiler will stop complaining.
The way you have it now is telling the compiler to check 2 condition, what if none of them are met? what is going to be returned?
You will need a else block but since your else if is redundant so else is what you need.
if (status == 0)
{
static NSString *kCellID = #"MessageCell";
MessageListCell *cell = (MessageListCell *) [tableView dequeueReusableCellWithIdentifier:kCellID];

UITableView loading wrong prototype cell from storyboard

I am having a really weird error that I cannot figure out, I really need some help right now. Basically, the tableView has three UITableViewCell subclasses that have their own prototype cell, and appear in their own section. But the prototype that is in the third section is also appearing in the second section. The weird part is that after putting some NSLogs into my code, the cell that is showing up in the second section section (which should be in the third section) is the correct subclass of UITableViewCell, but the content from the other prototype is showing up. I have no idea why this is happening. I have check to make sure the prototypes are of the right subclass, and the identifiers are all correct, and they are. Has anyone encountered this problem before? Sorry in advance for how long my cellForRowAtIndexPath: method is:

Wait, I figured it out. This is embarrassing, but I forgot a break in one of the cases in the switch statement!

}
The default alert isn't meant to take subviews. (while in ios6 and earlier add. subviews could be hacked in, this does NOT work in iOS7)
write your own custom UIView that looks and acts like an alert.
There's a lot of implementations around if you prefer not to do it yourself :) e.g. on cocoacontrols.com
From iOS 7 you need to add like this
[alertview setValue:tableView forKey:#"accessoryView"];

uitableview reloaddata cache?

I'm having some problems with an UITableView and the method reloadData.
I'm refreshing the tableView when clicking over a refresh button with the last info in a data base ordered descendingly so the most recent items should appear in first position.
Every cell in my tableview is being filled with custom labels and uiimageviews.
Well... the thing is that when I press that refresh button and new data is found, the first 5 rows (which are the ones that are being shown in the display) aren't updated but the following rows do. However, if I press over any of the 5 first rows, they call correctly to the tableView:didSelectRowAtIndexPath: method with the new data.
So, the problem is that the tableview's "visual" content of the first 5 rows is not being updated.
Anyone can help me with this?
Thanks!

Hmm, so you give each cell a unique cell identifier. Do you have a reason for that?
Mostly people try to patch their misunderstanding of iOS table views that way ...
When you reload your table this call UITableViewCell *cell = [ tableView dequeueReusableCellWithIdentifier: CellIdentifier];
will get you a cell to reuse (read already contains content).
But your code only works for "fresh" cells : if (cell == nil) {
, you're just not prepared for that case ...
