Can anyone help with creating complex cells with GMGridView with various elements such as UIViews, UIimageViews, UIButtons etc. These elements may have unique graphics for each cell.
I'd like to be able to do it with a nib file, but any code would be useful.
This is my first attempt at making a nib-based grid.. It works, but I'm sure someone cleverer than me can make it better, faster, and prettier.
Make a subclass of GMGridViewCell, which loads in a named nib:
@interface CustomGridCell : GMGridViewCell
@property (strong, nonatomic) IBOutlet UIButton *button;
@property (strong, nonatomic) IBOutlet UIView *customContentView;
+(CustomGridCell *)cellFromNibNamed:(NSString *)nibName;
+(CustomGridCell *)cellFromNibNamed:(NSString *)nibName
UIViewController *tempViewController = [[UIViewController alloc] initWithNibName:nibName bundle:nil];
CustomGridCell *customCell = (CustomGridCell *)tempViewController.view;
A nib is created to work with this. You create it buy using a UIView. Connect the FileOwner's view to this view. Within the nib, change the main view's class to CustomGridView. Within its main view, you place another view, which covers all the main view. Link this view to customContentView. Now add other stuff on top. I added a button for instance.
After importing CustomGridView in the Demo1ViewController header, change the cellForItemAtIndex in Demo1ViewController.m to looks like this:
- (GMGridViewCell *)GMGridView:(GMGridView *)gridView cellForItemAtIndex:(NSInteger)index
CustomGridCell *cell = (CustomGridCell*)[gridView dequeueReusableCell];
cell = (CustomGridCell *)[CustomGridCell cellFromNibNamed:@"CustomGridCell"];
[cell.button setTitle:[NSString stringWithFormat:@"button:%i", index] forState:UIControlStateNormal];
[cell.button addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
[[cell.contentView subviews] makeObjectsPerformSelector:@selector(removeFromSuperview)];
The property customContentView is used instead of contentView, so you can change the contentView to customContentView in other parts of Demo1ViewController if you want some effect to take place.
To get buttons (and other controls to work) I added this to GMGridView.m:
// discussion here: https://github.com/gmoledina/GMGridView/issues/68
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
if ( [touch.view isKindOfClass:[UIControl class]] ) return NO;
Thanks a lot ... it really help me a lot.
