UILabel setFrame is not resizing the label, even in layoutSubviews - objective-c

Question

I've got:
#import "CustomTableViewCell.h"
#interface CustomTableViewCell ()
#property (assign) CGRect titleFrame;
#property (assign) CGRect detailFrame;
#end
#implementation CustomTableViewCell
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
}
return self;
}
- (void)awakeFromNib
{
if (self.title != nil) {
self.titleFrame = self.title.frame;
}
if (self.detail != nil) {
self.detailFrame = self.detail.frame;
}
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
- (void) setTitleTo: (NSString *)text {
if (self.title == nil || text == nil) {
return;
}
CGSize maximumLabelSize = CGSizeMake(self.title.frame.size.width, FLT_MAX);
CGRect expectedLabelSize = [text boundingRectWithSize:maximumLabelSize
options:NSLineBreakByWordWrapping | NSStringDrawingUsesLineFragmentOrigin
attributes:#{NSFontAttributeName:self.title.font}
context:nil];
CGRect newFrame = self.title.frame;
newFrame.size.height = expectedLabelSize.size.height;
self.titleFrame = newFrame;
self.detail.lineBreakMode = NSLineBreakByWordWrapping;
self.detail.numberOfLines = 3;
[self.title setText:text];
[self setNeedsLayout];
}
- (void) setDetailTo: (NSString *)text {
if (self.detail == nil || text == nil) {
return;
}
CGSize maximumLabelSize = CGSizeMake(self.detail.frame.size.width, FLT_MAX);
CGRect expectedLabelSize = [text boundingRectWithSize:maximumLabelSize
options:NSLineBreakByWordWrapping | NSStringDrawingUsesLineFragmentOrigin
attributes:#{NSFontAttributeName:self.title.font}
context:nil];
CGRect newFrame = self.detail.frame;
newFrame.size.height = expectedLabelSize.size.height;
self.detailFrame = newFrame;
self.detail.lineBreakMode = NSLineBreakByWordWrapping;
self.detail.numberOfLines = 3;
[self.detail setText:text];
[self setNeedsLayout];
}
- (void) layoutSubviews {
[super layoutSubviews];
if (self.title != nil) {
NSLog(#"T: %#", self.title.text);
[self.title setFrame:self.titleFrame];
}
if (self.detail != nil) {
NSLog(#"D: %#", self.detail.text);
[self.detail setFrame:self.detailFrame];
}
}
#end
From what I'm reading here it should resize to fit the text.
and the NSLog output:
2014-10-08 20:48:29.474 Test[57397:613] T: Largest Metro
2014-10-08 20:48:29.475 Test[57397:613] D: Oahu metropolitan area
My understanding is the "Oahu metropolitan area" should be visible with "area" on the second line.

Three things you should change:
Move the size computation of your label to layoutSubviews.
The most precise way to compute a label's size is to use -[UILabel sizeThatFits:] to get the it's desired size.
Turn off auto layout
