UIButton image cannot set properly by taking names from the NSArray - ios

Question

Hello I have a problem like this. In my ViewController I have a delegate method like this
`
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSInteger)index reusingView:(UIView *)view
{
imgArray=[NSArray arrayWithObjects:#"water-dark.png",#"land-dark.png",#"animal-dark.png",#"air-dark.png",#"other-dark.png", nil];
button = (UIButton *)view;
if (button == nil)
{
//no button available to recycle, so create new one
//UIImage *image = [UIImage imageNamed:#"page.png"];
button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0.0f, 0.0f, 50, 50);
button.layer.cornerRadius=button.frame.size.width/2.0;
button.layer.borderWidth=2;
button.clipsToBounds = YES;
button.titleLabel.font = [button.titleLabel.font fontWithSize:15];
[button addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
}
//set button label
[button setTitle:[NSString stringWithFormat:#"%i", index] forState:UIControlStateNormal];
NSString *strIndex=[NSString stringWithFormat:#"%i",index];
[button setImage:[UIImage imageNamed:[NSString stringWithFormat:#"%#", [imgArray objectAtIndex:[strIndex intValue]]]] forState:UIControlStateNormal];
NSLog(#" CURRENT INDEX %i",index);
return button;
}
`
Here Im lacing 5 buttons on viewcontroller. Those 5 buttons titles are setting perfectly. I put the index number as the title. And now I want to get the image name from theimgArray` and set each image to the button. But the problem is
it set only 0th button image and the 4th(5th) button image only. But when I try to print the image name by taking from the array. All print on each button properly.
What should be the reason for this? And how can I solve this problem. Please help me
This is the output that I get currently. But I need to fill all 5 buttons with images in the array.

Hey First Of all There is no need to take a Button and its click event instead you can just return view in - (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSInteger)index reusingView:(UIView *)view in this method as I listed beolw.
and ya of course you want its click event instead you can use its one of the delegates - (void)carousel:(iCarousel *)carousel didSelectItemAtIndex:(NSInteger)index
This is your main method viewForItemAtIndex()
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSInteger)index reusingView:(UIView *)view
{
view = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 250, 250)];
((UIImageView *)view).image = [UIImage imageNamed:[imgArray objectAtIndex:index]];
view.alpha = 1.0;
[view.layer setCornerRadius:125];
[((UIImageView *)view).layer setMasksToBounds:YES];
[((UIImageView *)view) setContentMode:UIViewContentModeScaleAspectFit];
view.contentMode = UIViewContentModeCenter;
return view;
}
Here the arrImages is declared in .h file of your view controller and assigning it in viewDidLoad() method i.e. imgArray = [NSArray arrayWithObjects:#"water-dark.png",#"land-dark.png",#"animal-dark.png",#"air-dark.png",#"other-dark.png", nil];
and for knowledge it is not necessary to write or assign array of images with .png after every image name like you can also write imgArray = [NSArray arrayWithObjects:#"water-dark",#"land-dark",#"animal-dark",#"air-dark",#"other-dark", nil];
