How i use a NSMutableArray in two methods of my .m file? - ios

Question

I have in my .h file:
#import <UIKit/UIKit.h>
#import "SQLClient.h"
#interface mgrViewController : UIViewController <UITableViewDelegate, UITableViewDataSource,
SQLClientDelegate>{
NSMutableArray *pajaros;
}
#property (weak, nonatomic) IBOutlet UITableView *miTabla;
#property (nonatomic, retain)NSMutableArray *pajaros;
#end
And in my .m file:
#import "mgrViewController.h"
#import "Vista2.h"
#import "SQLClient.h"
#interface mgrViewController ()
#end
#implementation mgrViewController
#synthesize miTabla;
#synthesize pajaros;
- (void)viewDidLoad
{
[super viewDidLoad];
SQLClient* client = [SQLClient sharedInstance];
client.delegate = self;
[client connect:#"xxx.xxx.xxx.xxx:xxxx" username:#"xxxxxxxxxxx" password:#"xxxxxxxxxxxx" database:#"xxxxxxxxxxx" completion:^(BOOL success) {
if (success)
{
pajaros =[[NSMutableArray alloc]init];
[client execute:#"SELECT field FROM table WHERE field='xxxxxxxxx'" completion:^(NSArray* results) {
NSMutableString* resulta = [[NSMutableString alloc] init];
for (NSArray* table in results)
for (NSDictionary* row in table)
for (NSString* column in row){
//[results appendFormat:#"\n%# = %#", column, row[column]];
[resulta appendFormat:#"\n%#", row[column]];
[pajaros addObject:resulta];
}
[client disconnect];
}];
}
}];
self.miTabla.delegate = self;
self.miTabla.dataSource = self;
}
#pragma mark - SQLClientDelegate
- (void)error:(NSString*)error code:(int)code severity:(int)severity
{
NSLog(#"Error #%d: %# (Severity %d)", code, error, severity);
[[[UIAlertView alloc] initWithTitle:#"Error" message:error delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil, nil] show];
}
- (void)message:(NSString*)message
{
NSLog(#"Message: %#", message);
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(NSInteger) numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return pajaros.count;
}
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"celdaPajaros";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// elementos que contienen cada celda con sus tags
UILabel *labelTitulo = (UILabel *) [cell viewWithTag:10];
if(cell == nil){
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
labelTitulo.text = [pajaros objectAtIndex:indexPath.row];
return cell;
}
-(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
return 70.f;
}
#end
I added elements to NSMutableArray pajaros in -(void)viewDidLoad{}, and my question is, how I can use my NSMutableArray pajaros in -(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath?.
Thanks :)
If I use count on my NSMutable Array and print that number, the result is 1 (because I selected only A data), but only if I use:
...
[pajaros addObject:resulta];
}
NSInteger num = pajaros.count;
NSString *inStr = [NSString stringWithFormat: #"%ld", (long)num];
self.textView.text = inStr;
[client disconnect];
}];
...
But if I perform that count in another part of my .m file show me 0, my next questions becomes why my NSMutableArray contains only the data in:
...
[pajaros addObject:resulta];
}
[client disconnect];
}];
...
?
Thanks for the help!

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
//code here to dequecell
NSString *cellIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil)
{
cell.textLabel.text = [pajaraos objectAtIndex:indexPath.row];
}
return cell;
}
