how to add subviews from array to a uiview? - iphone

Question

i have my subviews stored in an array...what i want is to place these subviews to my main view from array....
for(int i=0;i<[imageViewArray count];i++)
{
NSLog(#" image array count is %d",[imageViewArray count]);
// countlayers= countlayers+1;
// [canvasView insertSubview:[imageViewArray objectAtIndex:i] atIndex:countlayers];
[canvasView addSubview:[imageViewArray objectAtIndex:i]];
}
can you tell me what i am doing wrong

Answer 1

If imageViewArray really contains initialized views, and if those views already have correct frame attributes, you're doing nothing wrong (even though your code could be more elegant).
Also, of course, we have to make sure that canvasView is indeed initialized and visible on the screen. Try setting its backgroundColor to something noticeable:
canvasView.backgroundColor = [UIColor greenColor];
Once you are sure the canvasView is actually being displayed, I would suggest using fast enumeration, which makes going through the array nicer, and logging your new subviews to make sure their frames are like you want them.
for (UIView *imageView in imageViewArray) //this is fast enumeration. You can get it through code completion by typing forin
{
NSLog(#"%#", imageView); //let's take a look at the imageView. What is its frame?
[canvasView addSubview:imageView];
}

Answer 2

Used enumeration to add images on your canvas View using imageViewArray and probably you are also missing with the setting frame of the images.
for (UIImageView *imageView in imageViewArray) //enumeration.
{
//let's set frame for image view before adding to canvasView
[imageView setFrame:CGRectMake(x,y,w,h)];
//Also make sure imageView has image or not
if(imageView.image)
[canvasView addSubview:imageView];
}
