Как исправить «sizeWithFont: constrainedToSize: lineBreakMode:» осуждается: предупреждение

Question

Мой код

CGSize textSize = [text sizeWithFont:font constrainedToSize:CGSizeMake(self.bounds.size.width - 106, CGFLOAT_MAX) lineBreakMode:NSLineBreakByWordWrapping]; 

Каждый знает, как я могу исправить это предупреждение?

Answer 1

Swift

// adjust the label height (top align text) 
// old 
var labelSize: CGSize = model.name.sizeWithFont(self.nameLabel.font, constrainedToSize: maxNameLabelSize, lineBreakMode: self.nameLabel.lineBreakMode) 
// new 
var labelSize: CGSize = model.name.boundingRectWithSize(maxNameLabelSize, options: .UsesLineFragmentOrigin, attributes: [NSFontAttributeName: self.nameLabel.font], context: nil).size 

Objective C

// adjust the label height (top align text) 
// old 
CGSize labelSize = [model.name sizeWithFont:self.nameLabel.font 
         constrainedToSize:_maxNameLabelSize 
          lineBreakMode:self.nameLabel.lineBreakMode]; 
// new 
CGSize labelSize = [model.name boundingRectWithSize:_maxNameLabelSize 
             options:NSStringDrawingUsesLineFragmentOrigin 
            attributes:@{NSFontAttributeName: self.nameLabel.font} 
             context:nil].size; 

Answer 2

Попробуйте ниже код:

NSAttributedString *attributedText = [[NSAttributedString alloc] initWithString:@"This is long text..!!!" attributes:@{NSFontAttributeName: self.lbl.font 
}]; 
CGRect rect = [attributedText boundingRectWithSize:(CGSize){self.lbl.frame.size.width, CGFLOAT_MAX} 
              options:NSStringDrawingUsesLineFragmentOrigin 
              context:nil]; 

NSLog(@"Height %f",rect.size.height); 
NSLog(@"Width %f",rect.size.width); 

Answer 3

Используйте это:

CGRect textRect = [text boundingRectWithSize:CGSizeMake(self.bounds.size.width - 106, CGFLOAT_MAX) options:NSStringDrawingUsesLineFragmentOrigin 
           attributes:@{NSFontAttributeName:[[UIFont fontWithName:@"YOUR_FONT_NAME" size:12.0f]]} 
           context:nil]; 

CGSize size = textRect.size;
