iOS UITableView content not loading - Property access result unused - ios

Question

I'm trying to load a table with content from Twitter. The table is in a UIView and being created in the drawRect()...but I keep getting a warning:
Property access result unused - getters should not be used for side effects
on each.
Nothing show up in my table.
Here's my .h file:
#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>
#import <Twitter/Twitter.h>
#import "ColorController.h"
#interface TwitterController : UIView <UITableViewDelegate, UITableViewDataSource> {
UIButton* btnCloseView;
UITableView* tblTweets;
UIImageView* imgTwitterIcon;
ColorController* colorManager;
NSMutableArray* tweetsArray;
NSString* twitterID;
}
#property (nonatomic, retain) NSString* twitterID;
- (void) getTweets;
- (void) closeWin;
#end
and my .m
#import "TwitterController.h"
#implementation TwitterController
#synthesize twitterID;
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
colorManager = [ColorController new];

Answer 1

drawRect is used to draw stuff inside this views, using drawing functions
You should move your views additions to the layoutSubviews
Instead of - (void)drawRect:(CGRect)rect use - (void)layoutSubviews
This may or may not solve your issues, but nevertheless its the correct approach
