Creating views on the fly from array

I need to create a a bunch a views on the fly. I was wondering what would be the best way to go about doing this as ill need to defin开发者_Go百科e coordinates, tag, colours of each view.

Would i need to create a multidimensional array and if so how can i do this?

CGRect viewRect1 = { 80.0, 200.0, 160.0, 100.0 };
UIview *myview1 = [[UIview alloc] initWithFrame:viewRect1];
[myview1 setBackgroundColor:[UIColor darkGrayColor]];

You need to define a structure to hold the data which is needed to create your UIView.

@interface MyViewDataHolder :NSObject
{
     CGRect mViewRect;
     UIColor* mDarkGrayColor;
     NSInterger mTag;
}

@end

Then create an object of above class AND assign the values in member then add that in your NSArray...

EDITED:

In MyViewDataHolder.h class

@interface MyViewDataHolder :NSObject
{
    CGRect mViewRect;
    UIColor* mDarkGrayColor;
    NSInteger mTag;
}
@property (nonatomic,assign) CGRect mViewRect;
@property (nonatomic,retain) UIColor* mDarkGrayColor;
@property (nonatomic,assign) NSInteger mTag;

@end

In MyViewDataHolder.mm class

#import "MyViewDataHolder.h"


@implementation MyViewDataHolder

@synthesize mViewRect,mDarkGrayColor,mTag;

-(void) dealloc
{
    [mDarkGrayColor release]
    mDarkGrayColor = nil;
}

Now How to use it ....

Create objects of MyViewDataHolder like below ...

MyViewDataHolder* myObj1 = [[MyViewDataHolder alloc] init];
myObj1.mViewRect = CGRectMake(x,y,width,height);
myObj1.tag = 1;
myObj1.mDarkGrayColor = [UIColor redColor];

Create as much as you need

Then Create an NSMutableArray and add each objects of MyViewDataHolder into NSMutableArray.

NSMutableArray* myArray = [[NSMutableArray alloc] init];
[myArray addObject:myObj1];
[myArray addObject:myObj2];
[myArray addObject:myObj3];
and So on ....

When you need the stored info you could use as below ...

for(int index =0; index < [myArray count]; index++)
{

     MyViewDataHolder* myObj = (MyViewDataHolder*)[myArray objectAtIndex:index];
     myView = [[UIView alloc] initWithFrame:myObj.mViewRect];
     //incriment x and y to refelect where you want your next view to be suituated 
     myView.tag = myObj.mTag; 
     myView.backgroundColor =  myObj.mDarkGrayColor;
     [self.view addSubview:myView];
     [myView release];
}

The code reflect the approach , Although I didn't compile the code So use it as reference

Thanks ,

You dont really need to store your views in an array unless its just for pure convenience.

You can create a variable amount views using a for loop:

UIView *myView;
int x=0, y=0; 
int viewWidth = 50, viewHeight = 50;
for(int i=0; i<numberOFView; i++){
     myView = [[UIView alloc] initWithFrame:CGRectMake(x,y,viewWidth,viewHeight)];
     //incriment x and y to refelect where you want your next view to be suituated 
     myView.tag = i+1; 
     [self.view addSubview:myView];
     [myView release];
}

Then to access each view in turn and carry out some work you can do the following:

for (UIView *view in self.view.subviews) {
    switch (view.tag) {
       case 1:
           //do something to the view 
           break;
       case 2:
           //do something to the view 
           break;
       case 3:
           //do something to the view
           break;
       //and so on...   
      default:
           break;
   }
}
