Goal: To develop a UITableView replacement that will be based on Auto Layout.
- Table view cell height will be calculated for you automatically. No more
heightForRowAtIndexPath:! - If you animate the height change of one of your table view cells, the table view will animate the other cells to fill in automatically.
Implement BMTableViews delegate methods:
numberOfRowsInSection:cellForRowAtIndexPath:
In your custom subclass of BMTableViewCell set its size using Auto Layout. See an example below (constraints are
set using Masonry framework).
- (id)init {
if (self = [super init]) {
label = UILabel.new;
[self addSubview:label];
label.numberOfLines = 0; // Label will be a variable height
label.preferredMaxLayoutWidth = 280;
[label makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.top);
make.left.equalTo(self.left);
}];
[self makeConstraints:^(MASConstraintMaker *make) {
make.bottom.equalTo(label.bottom);
}];
}
return self;
}
This Framework is still in early development and is not yet ready for shipping applications. That being said, we are
quickly working to fill out the rest of the standard features from UITableView. The main challenges remaining are:
- Table view cell reuse
- Partial table view loading (i.e. Only load the first 10 cells of a 100 cell tableview, then add more cells as the user scrolls)
