Answer 1

//Calculate the size based on the font and linebreak mode of your label

CGSize maxLabelSize = CGSizeMake(300,9999);

CGSize expectedLabelSize = [myString sizeWithFont:myLabel.font 
                        constrainedToSize:maxLabelSize 
                        lineBreakMode:myLabel.lineBreakMode]; 

//adjust the label the the new height.
CGRect newFrame = myLabel.frame;
newFrame.size.height = expectedLabelSize.height;
myLabel.frame = newFrame;

Try this

    [label sizeToFit];

Note that label will increase it's height keeping it's width the same.

Answer 3

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *text = displayText;

//CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);
CGSize constraint = CGSizeMake(tableView.frame.size.width - 30, 20000.0f);

CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:15.0f] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

CGFloat height = MAX(size.height, 44.0f);

return height + 30;

}

计算标签文字的大小，然后将坐标设置为

CGSize labelWidth=[_label.text sizeWithFont:[UIFont fontWithName:@"Verdana" size:12] constrainedToSize:CGSizeMake(200, 15) lineBreakMode:UILineBreakModeTailTruncation];
