I tried to break a label according to the text that contains. The code is below:
mnhmeioLabel.numberOfLines=0; mnhmeioLabel.lineBreakMode=NSLineBreakByWordWrapping; [mnhmeioLabel sizeToFit]; Although it seems to work only sometimes. I added a snapshot of my problem and what i want.
The problem is in red box that breaks the line with a way that i cannot understand. The result that i want is in the yellow box.
I think there might be a space in the text that is coming from json.
Try this:
NSString * jsonAfterOmittingSpace=[jsonString stringByReplacingOccurrencesOfString:@" " withString:@""]; and then put this string on label
Seems like your label width is changing at runtime. use a Fixed width/height for your UILabel
first YouShould get label Height base on text
UILabel *mnhmeioLabel = [[UILabel alloc] initWithFrame:giveYourframe]; [mnhmeioLabel setText:heregiveYourText] mnhmeioLabel.lineBreakMode=NSLineBreakByWordWrapping; // get height base on label text and size CGFloat height=[self getStringHeightforLabel:mnhmeioLabel]; //set fram after getting height cell.mnhmeioLabel.frame=CGRectMake(cell.mnhmeioLabel.frame.origin.x,cell.mnhmeioLabel.frame.origin.y,cell.mnhmeioLabel.frame.size.height,height); [cell.mnhmeioLabel sizeToFit]; // call this to get height
-(CGFloat)getStringHeightforLabel:(UILabel *)label { CGSize maximumLabelSize = CGSizeMake(label.frame.size.width,9999); CGSize stringSize= [label.text sizeWithFont:label.font constrainedToSize:maximumLabelSize lineBreakMode:label.lineBreakMode]; return stringSize.height; } 
[mnhmeioLabel sizeToFit]just after setting the text
