fix the memory issue warning when leaks in unable to find it

I am unsing the below code in a view controller.. I am fixing the memory issue problem. when I comment out the view did load even it takes a lot of memory above 80 MB what shuold I do to solve it. I changed all variable to strong to weak.

In the very end ,Nil all the Images you have declared previously.
After every pushtoViewController nil the reference you created for it.
Use #autoreleasepool.
keep weak references for Outlets and assign any strong references to nil** inviewWillDisapper: . You can present a viewController modally as a temporary interruption to obtain important information from the user.
Instead of creating new MKMapView's as needed in the app, I added an mkMapView property to my AppDelegate and only created it when needed. Once it has been created, it lives in the AppDelegate forever and I reuse that single instance everywhere needed. This really helped in reducing the amount of memory being used as I was previously instantiating a couple different MKMapView's and both were burning through memory pretty quickly.
Don’t use -imageNamed i’m saying it again don’t use imageNamed ever method because it caches the images. Use this instead of -imageNamed : (make a method on appDelegate and then call it anywhere you want)
-(UIImage *)method4TakeImagesFromBundel:(NSString *)nameOfImage
{ 
NSString fileLocation = [[NSBundle mainBundle] pathForResource:nameOftheImage ofType:#"png"];
UIImage yourImage = [[UIImage alloc] initWithContentsOfFile:fileLocation];
return yourImage;
}
After getting the image compress it and use it:
NSData *imgData= UIImageJPEGRepresentation(rainyImage,0.1 /compressionQuality/);
You can further resize it:
(UIImage *)imageWithImage:(UIImage *)image convertToSize:(CGSize)size {
UIGraphicsBeginImageContext(size);
[image drawInRect:CGRectMake(0, 0, size.width, size.height)];
UIImage *destImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return destImage;
}

Keyboard not resigning when i tap the return key (xcode)

I am trying to get the keyboard to go away, when I press the return key on my application heres my code from the .m:
- (BOOL)textFieldShouldReturn:(UITextField *)textField{
[textField resignFirstResponder];
return YES;
}
and the code in the .h:
- (BOOL)textFieldShouldReturn:(UITextField* )textField;
But when I run the application and hit the return key nothing happens. What am I doing wrong?
my .h:
#import <UIKit/UIKit.h>
#interface ChemicalInfoViewController: UIViewController{
IBOutlet UIScrollView *ChemicalInforScroller;
}
#property (strong, nonatomic) IBOutlet UITextField *PPMForChlTextField;
#property (strong, nonatomic) IBOutlet UITextField *GallonsForChlTextField;
#property (strong, nonatomic) IBOutlet UITextField *PPMForAlkTextField;
#property (strong, nonatomic) IBOutlet UITextField *GallonsForAlkTextField;
#property (strong, nonatomic) IBOutlet UITextField *PPMForPHTextField;
#property (strong, nonatomic) IBOutlet UITextField *GallonsForPHTextField;
- (IBAction)SumbitCDI:(UIButton *)sender;
#property (strong, nonatomic) IBOutlet UILabel *PPMLabelForChl;
#property (strong, nonatomic) IBOutlet UILabel *GallonsLabelForChl;
#property (strong, nonatomic) IBOutlet UILabel *PPMLabelForAlk;
#property (strong, nonatomic) IBOutlet UILabel *GallonsLabelForAlk;
#property (strong, nonatomic) IBOutlet UILabel *PPMLabelForPH;
#property (strong, nonatomic) IBOutlet UILabel *GallonsLabelForPH;
#property (strong, nonatomic) IBOutlet UITextField *ChlorinePoundsTextField;
#property (strong, nonatomic) IBOutlet UITextField *GallonsForAlkDecreaser;
#property (strong, nonatomic) IBOutlet UITextField *PhPoundsTextField;
#property (strong, nonatomic) IBOutlet UITextField *AlkPoundsTextField;
#property (strong, nonatomic) IBOutlet UITextField *LbsForAlkDecreaser;
#property (strong, nonatomic) IBOutlet UITextField *PPMForAlkDecreaser;
#property (strong, nonatomic) IBOutlet UITextField *LbsForPhDecreaser;
#property (strong, nonatomic) IBOutlet UITextField *PPMForPhDecreaser;
#property (strong, nonatomic) IBOutlet UITextField *GallonsForPhDecreaser;
- (IBAction) clickedBackground;
#interface ChemicalInfoViewController : UIView <UITextField>
#end
and my .m:
#import "ChemicalInfoViewController.h"
#interface ChemicalInfoViewController ()
#end
#implementation ChemicalInfoViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
[ChemicalInforScroller setScrollEnabled:YES];
[ChemicalInforScroller setContentSize:CGSizeMake(320, 1000)];
self.textField.delegate = self;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
- (IBAction) clickedBackground {
[self.view endEditing:YES];
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField{
[textField resignFirstResponder];
return YES;
}
In your .h, remove:
- (BOOL)textFieldShouldReturn:(UITextField* )textField;
And it will work as it should, given that in your .h, you conform to the protocol:
#interface yourViewController : UIView <UITextFieldDelegate>
And set up the delegate like so:
yourTextField.delegate = self;
Edit regarding to the #end:
In your .m, add a #end to the bottom; so , it becomes (scroll to the very bottom):
#implementation ChemicalInfoViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
[ChemicalInforScroller setScrollEnabled:YES];
[ChemicalInforScroller setContentSize:CGSizeMake(320, 1000)];
self.textField.delegate = self;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
- (IBAction) clickedBackground {
[self.view endEditing:YES];
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField{
[textField resignFirstResponder];
return YES;
}
#end //Here :-)
You didn't set the delegates for your textfields.
In "viewDidLoad" add
_ChlorinePoundsTextField.delegate = self;
_GallonsForAlkDecreaser.delegate = self;
_PhPoundsTextField.delegate = self;
_AlkPoundsTextField.delegate = self;
_LbsForAlkDecreaser.delegate = self;
_PPMForAlkDecreaser.delegate = self;
_LbsForPhDecreaser.delegate = self;
_PPMForPhDecreaser.delegate = self;
_GallonsForPhDecreaser.delegate = self;
none of these methods seemed to be working for some reason but what i did end up doing was creating a DidEndOnExit action and resigned the keyboard under that action for each textfield

Xcode saying that the variable "beacon" is undeclared?

- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated]
[[self.locationManager startRangingBeaconsInRegion: self.rangedRegion]
]}
- (void)viewDidDisappear:(BOOL)animated {
[super viewDidAppear:animated]
[[self.locationManager stopRangingBeaconsInRegion: self.rangedRegion]
]}
- (void)viewDidLoad
{
[super viewDidLoad];
self.tagname.text = [self.TagDetail objectForKey:#"Name"];
self.title = [self.TagDetail objectForKey:#"Name"];
NSString *proximity = #"near";
if ([beacon.proximity == CLProximityNear:]) {
NSLog(#"Show near");
[self.near setHidden:(NO)];
[self.far setHidden:(YES)];
[self.immediate setHidden:(YES)];
}
else if ([beacon.proximity == CLProximityFar]) {
NSLog(#"Show");
[self.near setHidden:(YES)];
[self.far setHidden:(NO)];
[self.immediate setHidden:(YES)];
}
else if ([beacon.proximity == CLProximityImmediate]) {
NSLog(#"Show");
[self.near setHidden: (YES)];
[self.far setHidden: (YES)];
[self.immediate setHidden: (NO)];
}
Heres the .h file
#interface TagDetailViewController : UIViewController
#property (nonatomic, strong) PFObject* TagDetail;
#property (strong, nonatomic)IBOutlet UILabel *tagname;
#property (nonatomic, strong)IBOutlet UIImageView *immediate;
#property (nonatomic, strong)IBOutlet UIImageView *near;
#property (nonatomic, strong)IBOutlet UIImageView *far;
#property (nonatomic, strong)IBOutlet UIButton *showOnMap;
#property CLLocationManager *locationManager;
#property CLBeaconRegion *rangedRegion;
#property NSUUID *artemisUUID;
#property CLBeaconMajorValue *major;
#property CLBeaconMinorValue *minor;
#property CLBeacon *proximity;
#end
Its telling me that the variable beacon is not identified, but doing so in the header file as *beacon doesn't remove any errors. What am I doing wrong? Im really new to this language so that is a large part of why Im running into errors, but I cant figure this one out.
You don't have a variable named beacon, you have a CLBeacon object named proximity.

Label Value Not Changing

I'm coding a program in Objective C that uses two different views to input data. One view merely displays the view (PSACurrentGame) and the other inputs the data (PSAEnterScores). I'm using a "prepareforsegue" method to pass data from PSAEnterScores to PSACurrentGame. The problem is the label isn't changing. Any idea why?

(The Name of the program is Phase 10 Scoring Application)
I have no idea why it says Unknown class PSA in Interface Builder file. I have no class named "PSA", it is merely the prefix for my classes.
prepareForSegue: is called before viewDidLoad: so your IBOutlet will be nil. Try setting the incoming value to a NSString and then use that string to populate the UIlabel on viewDidLoad:
For example
In your PSACurrentGame.h:
// create a property
#property(nonatomic,strong)NSString *gameName;
In your PSAEnterScores.m: modify your
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
PSACurrentGame *pass = (PSACurrentGame *)segue.destinationViewController;
pass.gameName=[NSString alloc]initWithString:pass.R2P1Score.text]
}
In your PSACurrentGame.m :
- (void)viewDidLoad
{
[super viewDidLoad];
// set text to your label
R3P1Score.text=gameName;
}

Labels not responding to changes

I have a problem, I have a couple view controllers. One is called PSACurrentGame, the other is called PSAEnterScores. PSACurrentGame is the parent class for PSAEnterScores. I'm trying to change labels in PSACurrentGame from PSAEnterScores. But I already figured that out with the parent class thing. The real problem is that, while I have the correct property linked with the variable the variable's text won't change. I confirmed that the lanbel responds to changes in the viewDidLoad method, but it won't respond to it being changed in a child class. Does anyone know why?
Code below:

If you need anything more just comment, and I'll add.
EDIT: I changed the text at the top, but I'll put it down here too. The label now responds to changes in its own class, but now in child classes. Do child classes only have read-only permission to access parent class variables?
I think you have two things you could improve:
1) Use IBOutletCollection instead of creating one for each of your interface controls;
2) Use a shared datasource and get notified when its values changes. Then you can make changes in your controls, inside their own ViewControllers, like that:
self.dataStore addObserver:self forKeyPath:#"gameScore" options:0 context:nil];
//...
- (void)observeValueForKeyPath:(NSString *)keyPath
ofObject:(id)object
change:(NSDictionary *)change
context:(void *)context {
if ([keyPath isEqual:#"gameScore"]) {
//update your IBOutletCollections...
}
}

I used this example in my application to transfer data between view controllers. So, it may helps: http://iphonedevsdk.com/forum/iphone-sdk-development/54859-sharing-data-between-view-controllers-and-other-objects-link-fixed.html
