Passing data From uiview to uiviewcontroller - ios

Question

after try 2 days and i'm losing my mind now... the main problem is simple.. i've button in uiview,, and i want to call method on uiviewcontroller ... here's the code
Uiview call headerView.h
#class HeaderView;
#protocol headerViewDelegate
- (void)tes:(HeaderView *)tes ratingDidChange:(float)rating;
#end
#interface HeaderView : UIView {
UIButton *test;
}
#property (nonatomic,strong) UIButton *test;
#property (assign) id <headerViewDelegate> delegate;
#end
and the Headerview.M
#import "HeaderView.h"
#import <QuartzCore/QuartzCore.h>
#implementation HeaderView
#synthesize test;
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame]; // not needed - thanks ddickison
if (self) {
test=[UIButton buttonWithType:UIButtonTypeRoundedRect];
test.frame=CGRectMake(30, 10, 100,40);
[test setTitle:#"Kampret" forState:UIControlStateNormal];
[test addTarget:self action:#selector(testdata:) forControlEvents:UIControlEventTouchUpInside];
}
[self addSubview:test];
return self;
}
- (id)initWithCoder:(NSCoder *)aDecoder {
if ((self = [super initWithCoder:aDecoder])) {
}
return self;
}
- (void)dealloc {
[super dealloc];
}
-(void)layoutSubviews{
self.backgroundColor=[UIColor whiteColor];
[self release]; // release object before reassignment to avoid leak - thanks ddickison
//self = [nib objectAtIndex:0];
self.layer.shadowColor = [[UIColor blackColor] CGColor];
self.layer.shadowOffset = CGSizeMake(1.0, 1.0);
self.layer.shadowOpacity = 0.40;
}
-(void)testdata:(id)sender{
[self.delegate tes:self ratingDidChange:1.1f];
}
#end
viewcontroller.h
#import <UIKit/UIKit.h>
#import "HeaderView.h"
#interface ReusableTableHeadersViewController : UITableViewController <headerViewDelegate> {
HeaderView *header;
}
#property(nonatomic,strong) HeaderView *header;
#end
viewcontroller.m
#import "viewcontroller.h"
#implementation ReusableTableHeadersViewController
#synthesize header;
#synthesize tblData, data;
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
header = [[HeaderView alloc] initWithFrame:CGRectMake(0, 0, 320, 120)];
[self.view addSubview:header];
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
}
- (void)dealloc {
[super dealloc];
}
-(void)tes:(HeaderView *)tes ratingDidChange:(float)rating{
NSLog(#"passing data==========%f",rating);
}
#end
i want to log the rating :
NSLog(#"passing data==========%f",rating);
from method:
-(void)testdata:(id)sender{
[self.delegate tes:self ratingDidChange:1.1f];
}
but it show nothing... why? because i use initwithframe?
dont blame me... i'm totally newbie here :)

Answer 1

You have not set delegate of headerview as view controller.
- (void)viewDidLoad {
[super viewDidLoad];
header = [[HeaderView alloc] initWithFrame:CGRectMake(0, 0, 320, 120)];
header.delegate = self;
[self.view addSubview:header];
}
