[xxxx]UILabe & UITableView&UITableViewCell問題集

1.怎么才能把UITableViewCell设为不可选中。 就像把按钮的enabled设为NO一样。全部鎖著cell.userInteractionEnabled = NO; 祇鎖一個cell.selectionStyle = UITableViewCellSelectionStyleNone; 2.如何讓uitableview固定 ANS:tableView.scrollEnabled 3. 如何換行 lblNeedSubscription = [[UILabel alloc] initWithFrame:frame]; [lblNeedSubscription setNumberOfLines:0];  // allows as many lines as needed [lblNeedSubscription setText:@"To access content\ryou need to be a paid subscrib 表示不能換行且自動將自縮小 factLabel.numberOfLines = 1 factLabel.minimumFontSize = 8.; factLabel.adjustsFontSizeToFitWidth = YES; In this way your text's font size will reduce down to (for example) 8 trying to fit your text within the label.numberOfLines = 1 is mandatory. For numberOfLines > 1 there is a method to figure out the size of final text through NSString's UIKit addition methods, for example: CGSize lLabelSIze = [yourText sizeWithFont: factLabel.font forWidth:factLabel.frame.size.width lineBreakMode:factLabel.lineBreakMode]; After that you can just resize your label using resulting lLabelSIze, for example (assuming that you will change only label's height): factLabel.frame = CGRectMake(factLabel.frame.origin.x, factLabel.frame.origin.y, factLabel.frame.size.width, lLabelSIze.height); 4.換顏色 label.textColor = [UIColor redColor]; 5.給予不同cell不同高度 - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {//判斷每個row所需要高度,判斷條件與產生cell一樣     if (!videoList) {         return 64;     }else if(indexPath.row<[videoList count]){         return 64;     }else{//顯示更多高度降低         return 48;     } }
