1.默认选中第一个item
dispatch_async(dispatch_get_main_queue(), ^{
if(indexPath.item == 0) {
[collectionView selectItemAtIndexPath:indexPath animated:YESscrollPosition:(UICollectionViewScrollPositionNone)];
}
});
2.在自定义cell里
- (void)setSelected:(BOOL)selected {
[supersetSelected:selected];
if(selected ==YES) {
self.contentView.backgroundColor = kColor(@"#794FF1");
self.titleL.textColor = UIColor.whiteColor;
}else{
self.contentView.backgroundColor = kColor(@"#EBE3FF");
self.titleL.textColor = kColor(@"#9C9C9C");
}
}
