Infinite grid view with UITableView-esque data source methods

If you want to have an infinite scroll view with our own grids, just drag IAInfiniteGridView, set and implement its data source, and your good to go!

Features

  • Circular mode
  • Custom set paging enabled
  • Familiar data source method to implement
  • Using reuse queue for better performance
  • Also, delegate method to accept did select grid

How To

  • Drag the IAInfiniteGridView to your project
  • Add the class via code or in Interface Builder
  • Set your view controller to conform IAInfiniteGridDataSource
  • Set its data source via code ``` infiniteGridView.dataSource = self
or via IB by ctrl+drag it to your view controller and add as its `dataSource`

* Implement the required data source methods

``` objective-c
- (UIView *)infiniteGridView:(IAInfiniteGridView *)gridView forIndex:(NSInteger)gridIndex {
    UIView *grid = [self.gridView dequeueReusableGrid];

    CGFloat gridWidth = [self infiniteGridView:gridView widthForIndex:gridIndex];
    CGRect frame = CGRectMake(0.0, 0.0, gridWidth, gridView.bounds.size.height);

    UILabel *numberLabel;
    if (grid == nil) {
        grid = [[UIView alloc] initWithFrame:frame];

        numberLabel = [[UILabel alloc] initWithFrame:frame];
        [numberLabel setBackgroundColor:[UIColor clearColor]];
        [numberLabel setTextColor:[UIColor whiteColor]];
        [numberLabel setFont:[UIFont boldSystemFontOfSize:(gridView.bounds.size.height * .4)]];
        [numberLabel setTextAlignment:NSTextAlignmentCenter];
        [numberLabel setTag:kNumberLabelTag];
        [grid addSubview:numberLabel];
    } else {
        grid.frame = frame;
        numberLabel = (UILabel *)[grid viewWithTag:kNumberLabelTag];
        numberLabel.frame = frame;
    }

    // set properties    
    NSInteger mods = gridIndex % [self numberOfGridsInInfiniteGridView:gridView];
    if (mods < 0) mods += [self numberOfGridsInInfiniteGridView:gridView];
    CGFloat red = mods * (1 / (CGFloat)[self numberOfGridsInInfiniteGridView:gridView]);
    grid.backgroundColor = [UIColor colorWithRed:red green:0.0 blue:0.0 alpha:1.0];

    // set text
    [numberLabel setText:[NSString stringWithFormat:@"[%d]", gridIndex]];

    return grid;
}

// this method is used for circular mode, not very useful for infinite mode
- (NSUInteger)numberOfInfiniteGrids {
    return 10;
}

- (CGSize)infiniteGridSize {    
    return CGSizeMake(150.0, 150.0);
}
  • Scroll the heck out of it!

For more clarity, please review the code in the sample project Infinite.

To Do
