Dynamic width and height for UILabel in iPhone

Having dynamic text to be displayed in application is a basic requirement.


When you want to display the text, we can calculate the size of the dynamic text using the below code.


  CGSize dynamicSize = [ sizeWithFont:[UIFont boldSystemFontOfSize:14.0] constrainedToSize:CGSizeMake(320, 999) lineBreakMode:UILineBreakModeWordWrap];


The font, constrainedToSize and lineBreakMode should be updated based on the requirement.


Now, dynamic height value can be derived like,


  NSLog(@"Dynamic Text Width: %f \nHeight: %f", dynamicSize.width, dynamicSize.height);


And, to update the UILabel, use the dynamicSize.height value,


  UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(0,0,dynamicSize.width, dynamicSize.height)];


And, ONE MORE THING,


Don't forget to set the numberOfLines property of UILabel to 0.

Multiple line of text in UIPickerView

UIPickerView is a user interface component available from iOS 2.0 and above. The basic need of UIPickerView is to select any one option from the list of data that are loaded to the picker view. But, by default, only one line of text is allowed to be displayed in a UIPickerView . Today, we will try to add multi-line text to an UIPickerView . To do so, we need to implement the viewForComponent api.   - ( UIView  *)pickerView:( UIPickerView  *)pickerView viewForRow:( NSInteger )row forComponent:( NSInteger )component reusingView:( UIView  *)view; In that method, type cast the view parameter to an UILabel.    UILabel *pickerLabel = ( UILabel *)view; Update the frame size of the label.    CGRect frame = CGRectMake ( 0 , 0 , 265 , 40 );    pickerLabel = [[[ UILabel alloc ] initWithFrame :frame] autorelease ]; Set the properties of the label as per requirement.    [pickerLabel setTextAlignment : UITextAlignmentLeft ];    [pickerLabel setBackgro
