Store Views in an array - ios

Question

I have three buttons and one view controller. I want to link three buttons to those three
different views (pages).
I've tried this by making three views and storing it in an mutable array.
ViewArray= [[NSMutableArray alloc]initWithCapacity:15];
CGRect viewRect = CGRectMake(10, 10, 100, 10);
//VIEW1
UIView* view1 = [[UIView alloc] initWithFrame:viewRect];
view1.backgroundColor = [UIColor redColor];
//VIEW2
UIView* view2 = [[UIView alloc] initWithFrame:viewRect];
view2.backgroundColor = [UIColor greenColor];
I added three buttons programmatically. After that for the action of each button I used this:
//action for each button
self.view = [ViewArray objectAtIndex:i];//where i={1,2,3} for different functions
but I am not getting what I want.

A better design would be to add all of the views invisibly, then change their opacity 0.0-1.1 to hide and show. (also, a key mistake in the OP is that the code replaces the view controller view with the subviews, instead of adding them)
CGRect viewRect = CGRectMake(10, 10, 100, 10);
//VIEW1
UIView* view1 = [[UIView alloc] initWithFrame:viewRect];
view1.backgroundColor = [UIColor redColor];
view1.tag = 1;
view1.alpha = 0.0;
[self.view addSubview:view1];
//VIEW2
UIView* view2 = [[UIView alloc] initWithFrame:viewRect];
view2.backgroundColor = [UIColor greenColor];
view1.tag = 2;
view1.alpha = 0.0;
[self.view addSubview:view2];
Add a property in your vc's interface that keeps track of the visible view:
#property(nonatomic, weak) UIView *visibleSubview;
Then the button action:
UIView *subview = [self.view viewWithTag:i];
//where i={1,2,3} for different functions
// i really needs to be 1,2,3 here, to correspond to the tags
[UIView animateWithDuration:0.5 animations:^{
subview.alpha = 1.0;
self.visibleSubview.alpha = 0.0;
} completion:^(BOOL finished) {
self.visibleSubview = subview;
}];

Well I'm not sure exactly what you want. But in general if you want to access any change multiple objects such as a UIView or UILabels, etc... You can just use and NSArray and a for loop to access and make all the changes without any extra code copies like so:
First of all, setup the NSArray with all your objects like so:
NSArray *_viewArray = #[view1, view2]; //etc....
And also setup an array with the different UIColors like so:
NSArray *_colourArray = #[[UIColor redColor], [UIColor greenColor]]; //etc....
And then when you want to access them and edit multiple UIViews or what ever objects, you can just use a for loop like so:
for (int loop = 0; loop < ([_viewArray count] - 1); loop++) {
((UIView*)_viewArray[loop]).backgroundColor = ((UIColor*)_colourArray[loop]);
}
I hope this helps you :)
