SKTagView

This library is derived from SFTagView,which tries to build a view displaying tags without using UICollectionView and supports auto layout.It's a good beginning,but not good enough.

So I tried to make it more auto layout.After having tried a lot,I inspired by UILabel.Now it just works like UILabel and supports single line and multi-line.

Installation with CocoaPods

platform :ios, '7.0'
pod "SKTagView"

Usage

Example

Check out the project. It contains the usages of normal way and in UITableViewCell.

Code

- (void)setupTagView
{
  self.tagView = ({
    SKTagView *view = [SKTagView new];
    view.backgroundColor = UIColor.cyanColor;
    view.padding    = UIEdgeInsetsMake(10, 25, 10, 25);
    view.insets    = 5;
    view.lineSpace = 2;
	__weak SKTagView *weakView = view;
	//Handle tag's click event
	view.didClickTagAtIndex = ^(NSUInteger index){
		//Remove tag
		[weakView removeTagAtIndex:index];
	};
    view;
  });
  [self.view addSubview:self.tagView];
  [self.tagView mas_makeConstraints:^(MASConstraintMaker *make) {
    UIView *superView = self.view;
    make.center.equalTo(superView);
    make.leading.equalTo(superView.mas_leading);
    make.trailing.equalTo(superView.mas_trailing);
  }];

  //Add Tags
  [@[@"Python", @"Javascript", @"HTML", @"Go", @"Objective-C",@"C", @"PHP"] enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop)
  {
    SKTag *tag = [SKTag tagWithText:obj];
    tag.textColor = UIColor.whiteColor;
    tag.bgColor = UIColor.orangeColor;
    tag.cornerRadius = 3;
	tag.fontSize = 15;
	tag.padding = UIEdgeInsetsMake(13.5, 12.5, 13.5, 12.5);

    [self.tagView addTag:tag];
  }];
}

Tips

When uses with UITableViewCell in multi-line mode,it MUST be set preferredMaxLayoutWidth before invoking

[cell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize].height + 1;
