Question

I have 3 UIbuttons in my with background image in my app…

for all those 3 buttons if images are assigned only lower half portion of button is clickable and upper half doesn’t work at all..

any idea why ?

I tried to put color for buttons to check if they have right CGRect but it looks proper…

Here is some code

    UIButton* segment=[[UIButton alloc] initWithFrame:CGRectMake(0+(i* segmentWidth) , 0,segmentWidth, 34)];

    segment.backgroundColor = [UIColor redColor];

    [segment addTarget:self action:@selector(segmentActionButton:) forControlEvents:UIControlEventTouchUpInside];

    [segment setTag:i];

    segment.titleLabel.font=[UIFont fontWithName:@"Arial" size:12.0];

    segment.autoresizingMask=UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleLeftMargin|UIViewAutoresizingFlexibleRightMargin;

    [segment setTitle:[mItems objectAtIndex:i] forState:UIControlStateNormal];
    [segment setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];


        [segment setBackgroundImage:[UIImage imageNamed:SEGMENT_IMAGE_INACTIVE_MAP] forState:UIControlStateNormal];

        [segment setBackgroundImage:[UIImage imageNamed:SEGMENT_IMAGE_ACTIVE_MAP] forState:UIControlStateHighlighted];


    [self addSubview:segment];
    [mButtonArray addObject:segment];
    [segment release];

Hope it helps..

May be the error occurs because you are creating button in alloc+initWithFrame way. I’m not sure but try to create button in such way:

UIButton* segment = [UIButton buttonWithType:UIButtonTypeCustom];
segment.frame = CGRectMake(0+(i* segmentWidth) , 0,segmentWidth, 34);

And remove line [segment release]; as you will create autoreleased object.
