Question

I have UITableView with custom cells, which contain uilabels.
I am using it to show comments and it must have flexible height.
How can I do it?
I have code, which counting number of rows with help of uilabel.text length, but it is wrong way. Have you any ideas?

Answer 1

Use UILabel with numberOfLines set to zero.

Then, for making sure that your label actually fits into the cell, get the dimensions from the NSString UIKit extension like this;

CGFloat cellWidth = 320.0f; //example width....
labelSize = [label.text sizeWithFont:label.font constrainedToSize:CGSizeMake(cellWidth, FLT_MAX)];

From the NSString reference;
sizeWithFont:constrainedToSize:

Returns the size of the string if it were rendered and constrained to
the specified size.

- (CGSize)sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size

Parameters font The font to use for computing the string size. size
The maximum acceptable size for the string. This value is used to
calculate where line breaks and wrapping would occur. Return Value The
width and height of the resulting string’s bounding box.
