Somebody knows how to use -boundingRectWithSize:options:attributes:context: as a replacement of the deprecated ”sizeWithFont:constrainedToSize:” method in this case.
CGSize labelSize = [self.mainLabel.text sizeWithFont:self.mainLabel.font constrainedToSize:CGSizeMake(CGFLOAT_MAX, CGRectGetHeight(self.bounds))];
Gets the warning: 'sizeWithFont:constrainedToSize:' is deprecated: first deprecated in iOS 7.0 - Use -boundingRectWithSize:options:attributes:context:
This is the hole code piece:
// calculate the label size
CGSize labelSize = [self.mainLabel.text sizeWithFont:self.mainLabel.font constrainedToSize:CGSizeMake(CGFLOAT_MAX, CGRectGetHeight(self.bounds))];
each_object(self.labels, ^(UILabel *label) {
CGRect frame = label.frame;
frame.origin.x = offset;
frame.size.height = CGRectGetHeight(self.bounds);
frame.size.width = labelSize.width + 2.f /*Magic number*/;
label.frame = frame;
// Recenter label vertically within the scroll view
label.center = CGPointMake(label.center.x, roundf(self.center.y - CGRectGetMinY(self.frame)));
offset += CGRectGetWidth(label.bounds) + self.labelSpacing;
});
At the moment you have...
CGSize labelSize = [self.mainLabel.text sizeWithFont:self.mainLabel.font constrainedToSize:CGSizeMake(CGFLOAT_MAX, CGRectGetHeight(self.bounds))];
So use...
CGRect boundingRect = [self.mainLabel.text boundingRectWithSize:CGSizeMake(CGFLOAT_MAX, CGRectGetHeight(self.bounds))
options:NSStringDrawingUsesLineFragmentOrigin
context:nil];
CGSize labelSize = boundingRect.size;
That should work.
Or... with attributes...
CGRect boundingRect = [self.mainLabel.text boundingRectWithSize:CGSizeMake(CGFLOAT_MAX, CGRectGetHeight(self.bounds))
options:NSStringDrawingUsesLineFragmentOrigin
attributes:#{NSFontAttributeName:self.mainLabel.font}
context:nil];
For example this way
-(CGFloat)getLabelSize:(UILabel *)label fontSize:(NSInteger)fontSize
{
NSDictionary *attributesDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
[UIFont systemFontOfSize:fontSize], NSFontAttributeName,
nil];
CGRect frame = [label.text boundingRectWithSize:CGSizeMake(270, 2000.0)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:attributesDictionary
context:nil];
CGSize size = frame.size;
return size.height;
}

i am displaying different items in custom table cell. when i try to display multiline uilabel text. it si only showing single line. even though i calculate the label height
also i try to set new frame with new height after calculation.
my code is as follows:
+(CGRect )getlabelHeight:(CGRect)frame withFontName:(NSString *)font andFontSize:(float)fontSize andText:(NSString *)text
{
CGSize constrainedSize = CGSizeMake(frame.size.width, 9999);
NSDictionary *attributesDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
[UIFont fontWithName:font size:fontSize], NSFontAttributeName,
nil];
NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:text attributes:attributesDictionary];
CGRect requiredHeight = [string boundingRectWithSize:constrainedSize options:NSStringDrawingUsesLineFragmentOrigin context:nil];
if (requiredHeight.size.width > constrainedSize.width) {
requiredHeight = CGRectMake(0,0, constrainedSize.width, requiredHeight.size.height);
}
CGRect newFrame = frame;
newFrame.size.height = requiredHeight.size.height;
frame = newFrame;
return frame;
}
my tabelview method is as follows:
CGRect descFrame=[Utility getlabelHeight:CGRectMake(65,35+titleFrame.size.height, 250, 20) withFontName:appFont andFontSize:15 andText:[[allComments objectAtIndex:indexPath.row]valueForKey:#"comment"]];
NSLog(#"%# \n %f",[[allComments objectAtIndex:indexPath.row]valueForKey:#"comment"],descFrame.size.height);
[cell.title setFont:[UIFont fontWithName:appFont size:15]];
[cell.title setText:[[allComments objectAtIndex:indexPath.row]valueForKey:#"comment"]];
[cell.title setLineBreakMode:NSLineBreakByWordWrapping];
[cell.title setNumberOfLines:0];
[cell.title setFrame:descFrame];
[cell.title setTextColor:[UIColor blackColor]];
Please help me!!1 i am screwed...
thanks you!!!
I have the following method that I used in iOS6 but with iOS7 I'm getting errors on
CGSize labelHeight = [tweetText sizeWithFont:[UIFont systemFontOfSize:13.0f] constrainedToSize:CGSizeMake(self.tweetsTableView.bounds.size.width - 84, 4000)];
full method below, any ideas on how to amend for iOS7?
- (CGFloat)heightForCellAtIndex:(NSUInteger)index {
NSDictionary *tweet = self.tweets[index];
CGFloat cellHeight = 50;
NSString *tweetText = tweet[#"text"];
CGSize labelHeight = [tweetText sizeWithFont:[UIFont systemFontOfSize:13.0f] constrainedToSize:CGSizeMake(self.tweetsTableView.bounds.size.width - 84, 4000)];
cellHeight += labelHeight.height;
return cellHeight;
}
I know this is an old question & late answer, but it's still very relevant,
This sizeWithFont method is now deprecated, this new method works best
NSString *content = **Whatever your label's content is expected to be**
CGSize maximumLabelSize = CGSizeMake(390, 1000);
NSDictionary *stringAttributes = [NSDictionary dictionaryWithObject:[UIFont systemFontOfSize:13] forKey: NSFontAttributeName];
CGSize newExpectedLabelSize = [content boundingRectWithSize:maximumLabelSize options:NSStringDrawingTruncatesLastVisibleLine|NSStringDrawingUsesLineFragmentOrigin attributes:stringAttributes context:nil].size;
So you can adjust your label (or table cell etc) to
label.frame.size.height = newExpectedLabelSize.height;
I hope this helps, cheers, Jim.
Add this lines:
UIFont *font = [UIFont boldSystemFontOfSize:16];
CGRect new = [string boundingRectWithSize:CGSizeMake(200, 300) options:NSStringDrawingUsesFontLeading attributes:#{NSFontAttributeName: font} context:nil];
CGSize stringSize= new.size;
In iOS7, sizeWithFont is deprecated, so I am using boundingRectWithSize(which returns a CGRect value). My code:
UIFont *fontText = [UIFont fontWithName:[AppHandlers zHandler].fontName size:16];
// you can use your font.
CGSize maximumLabelSize = CGSizeMake(310, 9999);
CGRect textRect = [myString boundingRectWithSize:maximumLabelSize
options:NSStringDrawingUsesLineFragmentOrigin
attributes:#{NSFontAttributeName:fontText}
context:nil];
expectedLabelSize = CGSizeMake(textRect.size.width, textRect.size.height);
In textRect, I'm getting a size greater than my maximumLabelSize, a different size than when using sizeWithFont. How can I resolve this issue?
How about create new label and using sizeThatFit:(CGSize)size ??
UILabel *gettingSizeLabel = [[UILabel alloc] init];
gettingSizeLabel.font = [UIFont fontWithName:#"YOUR FONT's NAME" size:16];
gettingSizeLabel.text = #"YOUR LABEL's TEXT";
gettingSizeLabel.numberOfLines = 0;
gettingSizeLabel.lineBreakMode = NSLineBreakByWordWrapping;
CGSize maximumLabelSize = CGSizeMake(310, CGFLOAT_MAX);
CGSize expectSize = [gettingSizeLabel sizeThatFits:maximumLabelSize];
Edit: This upper code is not good for ios 7 and above, so please use below:
CGRect textRect = [myString boundingRectWithSize:maximumLabelSize
options:NSStringDrawingUsesLineFragmentOrigin| NSStringDrawingUsesFontLeading
attributes:#{NSFontAttributeName:fontText}
context:nil];
Maybe you need to provide additional option to the method that is suggested in this answer:
CGSize maximumLabelSize = CGSizeMake(310, CGFLOAT_MAX);
CGRect textRect = [myString boundingRectWithSize:maximumLabelSize
options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading)
attributes:#{NSFontAttributeName: fontText}
context:nil];
Here is my working code snippet:
NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithDictionary:attributeDict];
NSString *headline = [dict objectForKey:#"title"];
UIFont *font = [UIFont boldSystemFontOfSize:18];
CGRect rect = [headline boundingRectWithSize:CGSizeMake(300, 1000) options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading attributes:#{NSFontAttributeName:font} context:nil];
CGFloat height = roundf(rect.size.height +4)
I added 4px to the calculated height, because without these 4px, there is one line missing.
I use this code snippet in a tableView and add the "height" to an array of NSNumbers and I get the correct cell height for the default textLabel.
Add 4 more pixel if you want more space under the text in the textLabel.
**** UPDATE ****
I do not agree with the "width bug of 40px", I shout be the 4px of missing height, because 4px is the default height of a space between a letter and the bound of a single line.
You can check it with a UILabel, for a fontsize of 16 you need a UILabel height of 20.
But if your last line has no "g" or whatever in it, the measuring could be miss the 4px of height.
I rechecked it with a little method, I get an accurate height of 20,40 or 60
for my label and a right width less than 300px.
To support iOS6 and iOS7, you can use my method:
- (CGFloat)heightFromString:(NSString*)text withFont:(UIFont*)font constraintToWidth:(CGFloat)width
{
CGRect rect;
float iosVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
if (iosVersion >= 7.0) {
rect = [text boundingRectWithSize:CGSizeMake(width, 1000) options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading attributes:#{NSFontAttributeName:font} context:nil];
}
else {
CGSize size = [text sizeWithFont:font constrainedToSize:CGSizeMake(width, 1000) lineBreakMode:NSLineBreakByWordWrapping];
rect = CGRectMake(0, 0, size.width, size.height);
}
NSLog(#"%#: W: %.f, H: %.f", self, rect.size.width, rect.size.height);
return rect.size.height;
}
**** UPGRADE ****
Thanks to your comments, I upgraded my function as followed. Since sizeWithFont is deprecated and you will get a warning in XCode, I added the diagnostic-pragma-code to remove the warning for this particular function-call/block of code.
- (CGFloat)heightFromStringWithFont:(UIFont*)font constraintToWidth:(CGFloat)width
{
CGRect rect;
if ([self respondsToSelector:#selector(boundingRectWithSize:options:attributes:context:)]) {
rect = [self boundingRectWithSize:CGSizeMake(width, 1000) options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading attributes:#{NSFontAttributeName:font} context:nil];
}
else {
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wdeprecated-declarations"
CGSize size = [self sizeWithFont:font constrainedToSize:CGSizeMake(width, 1000) lineBreakMode:NSLineBreakByWordWrapping];
rect = CGRectMake(0, 0, size.width, size.height);
#pragma GCC diagnostic pop
}
return ceil(rect.size.height);
}
In addition to the 4px topic:
depending which font and font-weight you use, the calculation returns different height-values. In my case: HelveticaNeue-Medium with a fontsize of 16.0 returns a line-height of 20.0 for a single line but 39.0 for two lines, 78px for 4 lines --> 1px missing for every line - beginning with line 2 - but you want to have your fontsize + 4px linespace for every line you have to get a height-result.
Please keep that in mind while coding!
I don´t have a function yet for this "problem" but I will update this post when I´m finished.
If I understand correctly, you are using boundingRectWithSize: just as a way of getting the size you would get with sizeWithFont (meaning you want directly the CGSize, not the CGRect)?
This looks like what you are looking for :
Replacement for deprecated sizeWithFont: in iOS 7?
They are using sizeWithAttributes: to get the size, as a replacement for sizeWithFont.
Do you still get the wrong size using something like this :
UIFont *fontText = [UIFont fontWithName:[AppHandlers zHandler].fontName size:16];
// you can use your font.
expectedLabelSize = [myString sizeWithAttributes:#{NSFontAttributeName:fontText}];
The #SoftDesigner's comment has worked for me
CGRect descriptionRect = [description boundingRectWithSize:CGSizeMake(width, 0)
options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading)
attributes:#{NSFontAttributeName : [UIFont systemFontOfSize:12]}
context:nil];
result = ceil(descriptionRect.size.height);
for finding size of label run time sizewithfont is deprecated for iOS 7.0 instead of that you have to use -boundingRectWithSize:options:attributes:context: method
you can use it like below code
CGSize constraint = CGSizeMake(MAXIMUM_WIDHT, TEMP_HEIGHT);
NSRange range = NSMakeRange(0, [[self.message body] length]);
NSDictionary *attributes = [YOUR_LABEL.attributedText attributesAtIndex:0 effectiveRange:&range];
CGSize boundingBox = [myString boundingRectWithSize:constraint options:NSStringDrawingUsesFontLeading attributes:attributes context:nil].size;
int numberOfLine = ceil((boundingBox.width) / YOUR_LABEL.frame.size.width);
CGSize descSize = CGSizeMake(ceil(boundingBox.width), ceil(self.lblMessageDetail.frame.size.height*numberOfLine));
CGRect frame=YOUR_LABEL.frame;
frame.size.height=descSize.height;
YOUR_LABEL.frame=frame;
here you have to give width to maximum length for finding height or width.
try this it is working for me.
If the sizeWithFont:constrainedToSize:lineBreakMode: method is deprecated in iOS7, how can I automatically resize a UILabel to dynamically adjust its height and width to fit the text?
I ended up using this. Works for me. This does not work with IBOutlets object but useful when computing dynamically the height of the text on uitableview's heightForRowAtIndexPath: method.
NSDictionary *attributesDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
[UIFont fontWithName:#"FontName" size:15], NSFontAttributeName,
nil];
CGRect frame = [label.text boundingRectWithSize:CGSizeMake(263, 2000.0)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:attributesDictionary
context:nil];
CGSize size = frame.size;
This should work in iOS6 and iOS7, but will break your label constraints (you need to set them all back programatically if needed):
-(void)resizeHeightForLabel: (UILabel*)label {
label.numberOfLines = 0;
UIView *superview = label.superview;
[label removeFromSuperview];
[label removeConstraints:label.constraints];
CGRect labelFrame = label.frame;
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
CGRect expectedFrame = [label.text boundingRectWithSize:CGSizeMake(label.frame.size.width, 9999)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:[NSDictionary dictionaryWithObjectsAndKeys:
label.font, NSFontAttributeName,
nil]
context:nil];
labelFrame.size = expectedFrame.size;
labelFrame.size.height = ceil(labelFrame.size.height); //iOS7 is not rounding up to the nearest whole number
} else {
#pragma GCC diagnostic ignored "-Wdeprecated-declarations"
labelFrame.size = [label.text sizeWithFont:label.font
constrainedToSize:CGSizeMake(label.frame.size.width, 9999)
lineBreakMode:label.lineBreakMode];
#pragma GCC diagnostic warning "-Wdeprecated-declarations"
}
label.frame = labelFrame;
[superview addSubview:label];
}
Add this method to your viewController and use it like this:
[self resizeHeightForLabel:myLabel];
//set new constraints here if needed
I am working on a project to make the NSString on UILabel Width and Height dynamically.
I tried with:
NSString *text = [messageInfo objectForKey:#"compiled"];
writerNameLabel.numberOfLines = 0;
writerNameLabel.textAlignment = UITextAlignmentRight;
writerNameLabel.backgroundColor = [UIColor clearColor];
CGSize constraint = CGSizeMake(296,9999);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE]
constrainedToSize:constraint
lineBreakMode:UILineBreakModeWordWrap];
NSLog(#"sizewidth = %f, sizeheight = %f", size.width, size.height);
NSLog(#"writerNameLabel.frame.size.width 1 -> %f",writerNameLabel.frame.size.width);
[writerNameLabel setFrame:CGRectMake(writerNameLabel.frame.origin.x, writerNameLabel.frame.origin.y, size.width, size.height)];
CGRect labelFram = writerNameLabel.frame;
labelFram.origin.x = cell.frame.size.width - writerNameLabel.frame.size.width - 80;
writerNameLabel.frame = labelFram;
NSLog(#"writerNameLabel.frame.size.width 2-> %f",writerNameLabel.frame.size.width);
Please see the green bubble not the grey one.
Still not right.
The code for bubble
bubbleImageView.frame = CGRectMake(writerNameLabel.frame.origin.x, writerNameLabel.frame.origin.y, writerNameLabel.frame.size.width+15, writerNameLabel.frame.size.height+5);
Please Advise! Thanks!
That's because you did not reuse the table cell, the structure should be like:
NSString *text = [messageInfo objectForKey:#"compiled"];
if(cell == nil)
{
writerNameLabel.numberOfLines = 0;
writerNameLabel.textAlignment = UITextAlignmentRight;
writerNameLabel.backgroundColor = [UIColor clearColor];
[cell addSubview:writerNameLabel];
}
else {
writerNameLabel = (UILabel *)[cell viewWithTag:WRITER_NAME_LABEL_TAG];
}
CGSize constraint = CGSizeMake(296,9999);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE]
constrainedToSize:constraint
lineBreakMode:UILineBreakModeWordWrap];
[writerNameLabel setFrame:CGRectMake(writerNameLabel.frame.origin.x, writerNameLabel.frame.origin.y, size.width, size.height)];
I've been gone through and answered some of your question, that's correct way to write your tableview controller. And your problem will be solved.
