ios objective C Bool not setting
boolean, ios, iphone, objective-c
Solution
You've placed your NSLog in the initWithFrame method. This is called on the line before you set textField.hasBackGroundImage, when the value is still NO.
If you want to see this value get set, add the following method to MyCustomTextField:
- (void)setHasBackGroundImage:(BOOL)flag
{
_hasBackGroundImage = flag;
}
Then put a breakpoint on this method. You should see it hit as soon as you set it.
Problem
im creating a custom UITextField, but is not setting a BOOL?? MyCustomTextField.h ``` #import <UIKit/UIKit.h> @interface OMTextField : UIControl <UITextFieldDelegate> { UITextField *_theTextField; BOOL _hasBackGroundImage; } @property (nonatomic, retain)UITextField *theTextField; @property (nonatomic) BOOL hasBackGroundImage; @end ``` MyCustomTextField.m ``` #import "OMTextField.h" @implementation OMTextField @synthesize theTextField = _theTextField; @synthesize hasBackGroundImage = _hasBackGroundImage; - (void)dealloc { [_theTextField release]; [super dealloc]; } - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { // Initialization code self.theTextField = [[[UITextField alloc]initWithFrame:CGRectMake(0, 0, frame.size.width, frame.size.height)]autorelease]; //self.theTextField.borderStyle = UITextBorderStyleLine; self.theTextField.text = @"textField"; self.theTextField.delegate = self; if (self.hasBackGroundImage) { NSLog(@"lo tienes"); } if (!self.hasBackGroundImage) { NSLog(@"nana tienes"); } [self addSubview:self.theTextField]; } return self; } /* // Only override drawRect: if you perform custom drawing. // An empty implementation adversely affects performance during animation. - (void)drawRect:(CGRect)rect { // Drawing code } */ @end ``` and the call in my MainVC: ``` MyCustomTextField *textField = [[[MyCustomTextField alloc]initWithFrame:CGRectMake(400, 160, 150, 40)]autorelease]; textField.hasBackGroundImage = YES; textField.backgroundColor = [UIColor grayColor]; textField.theTextField.borderStyle = UITextBorderStyleLine; [self.view addSubview:textField]; ``` so it shows fine, but as you see im setting `textField.hasBackGroundImage = YES;` but when executed, i see the message for BOOL = NO?? ``` nana tienes ``` So what Im I missing?, why is this not evaluated as YES?? thanks!
