Custom NSTableCellView - objective-c

Question

I want to make a NSTableView with customs NSTableCellView, here's what I've done so far :
AppDelegate.h :
#import <Cocoa/Cocoa.h>
#import "TheView.h"
#interface AppDelegate : NSObject <NSApplicationDelegate, NSTableViewDataSource, NSTableViewDelegate>
#property (weak) IBOutlet NSTableView *tableView;
#property (copy) NSMutableArray *tableContent;
#property (assign) IBOutlet NSWindow *window;
-(IBAction)addRow:(id)sender;
#end
AppDelegate.m :
#import "AppDelegate.h"
#implementation AppDelegate
#synthesize tableContent;
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
tableContent = [[NSMutableArray alloc]init];
}
-(id)init{
self = [super init];
if (self) {
tableContent = [[NSMutableArray alloc]init];
}
return self;
}
-(NSInteger)numberOfRowsInTableView:(NSTableView *)tableView {
NSLog(#"%#",tableContent); //Here tableContent is empty
return [tableContent count];
}
- (NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row {
NSView *result = [tableView makeViewWithIdentifier:tableColumn.identifier owner:self];
TheView *view = [tableContent objectAtIndex:row];
result = view;
return result;
}
-(IBAction)addRow:(id)sender {
TheView *view = [[TheView alloc]init];
[tableContent addObject:view];
NSLog(#"%#",tableContent); //Here tableContent result with the correct number of objects
[_tableView reloadData];
}
But when I try to add an object, nothing happens... TheView is a subclass of NSTableCellView, it's drawing a simple rect.
I've of course added NSTableViewDataSource and NSTableViewDelegate.
UPDATE 2
After further researches in my code, I found that in numberOfRowsInTableView, tableContent resulted empty or with the number of object I initialized my array with...

The views your creating seem to have no size. You could try replacing the view initialization, and use initWithFrame instead of init
[[TheView alloc]initWithFrame:CGRectMake(0, 0, 100, 20)];
Also, you can try set in fame on the viewForTableColumn method.
