Programmatically Creating UILabel

Question

I know this should be very simple  but I ve been really struggling with creating a UILabel programmatically and getting it to behave the way I would like   All I want is to be able to create a label  set the maximum attributes as far as height  width and font size  and then have the text get smaller AND OR just truncate the text to accommodate long strings of text   Let s say that I want my label to have text that has a maximum width of 380  a maximum height of 20 and a maximum font size of 12    So here is what I have attempted to do to create such a label   UILabel  fromLabel     UILabel alloc initWithFrame CGRectMake 91  15  0  0    fromLabel text    self fromSender   fromLabel font    UIFont fontWithName ProximaNovaSemibold size 12     custom font fromLabel numberOfLines   1  fromLabel baselineAdjustment   YES  fromLabel adjustsFontSizeToFitWidth   YES  fromLabel adjustsLetterSpacingToFitWidth   YES  fromLabel size    fromLabel text sizeWithFont fromLabel font constrainedToSize CGSizeMake 380  20  lineBreakMode NSLineBreakByTruncatingTail   fromLabel minimumScaleFactor   MIN SCALE FACTOR  fromLabel clipsToBounds   YES  fromLabel backgroundColor    UIColor clearColor   fromLabel textColor    UIColor blackColor   fromLabel textAlignment   NSTextAlignmentLeft   collapsedViewContainer addSubview fromLabel     Ok  so the label appears  but the text is larger than 12 and the height always comes out to be 21   Even if I change the height and text size values to extreme sizes  this code creates a label of some fixed size that can t be adjusted  The only thing I can seem to make smaller is the width    I must be over looking something basic  but I really can t figure out how to get my desired result  nor do I understand why I m getting the behavior that I am getting

here is how to create UILabel Programmatically..

1) Write this in .h file of your project.

UILabel *label;

2) Write this in .m file of your project.

label=[[UILabel alloc]initWithFrame:CGRectMake(10, 70, 50, 50)];//Set frame of label in your viewcontroller.
[label setBackgroundColor:[UIColor lightGrayColor]];//Set background color of label.
[label setText:@"Label"];//Set text in label.
[label setTextColor:[UIColor blackColor]];//Set text color in label.
[label setTextAlignment:NSTextAlignmentCenter];//Set text alignment in label.
[label setBaselineAdjustment:UIBaselineAdjustmentAlignBaselines];//Set line adjustment.
[label setLineBreakMode:NSLineBreakByCharWrapping];//Set linebreaking mode..
[label setNumberOfLines:1];//Set number of lines in label.
[label.layer setCornerRadius:25.0];//Set corner radius of label to change the shape.
[label.layer setBorderWidth:2.0f];//Set border width of label.
[label setClipsToBounds:YES];//Set its to YES for Corner radius to work.
[label.layer setBorderColor:[UIColor blackColor].CGColor];//Set Border color.
[self.view addSubview:label];//Add it to the view of your choice.

Does the following work    UIFont   customFont    UIFont fontWithName ProximaNovaSemibold size 12     custom font NSString   text    self fromSender    CGSize labelSize    text sizeWithFont customFont constrainedToSize CGSizeMake 380  20  lineBreakMode NSLineBreakByTruncatingTail    UILabel  fromLabel     UILabel alloc initWithFrame CGRectMake 91  15  labelSize width  labelSize height    fromLabel text   text  fromLabel font   customFont  fromLabel numberOfLines   1  fromLabel baselineAdjustment   UIBaselineAdjustmentAlignBaselines     or UIBaselineAdjustmentAlignCenters  or UIBaselineAdjustmentNone fromLabel adjustsFontSizeToFitWidth   YES  fromLabel adjustsLetterSpacingToFitWidth   YES  fromLabel minimumScaleFactor   10 0f 12 0f  fromLabel clipsToBounds   YES  fromLabel backgroundColor    UIColor clearColor   fromLabel textColor    UIColor blackColor   fromLabel textAlignment   NSTextAlignmentLeft   collapsedViewContainer addSubview fromLabel     edit    I believe you may encounter a problem using both adjustsFontSizeToFitWidth and minimumScaleFactor  The former states that you also needs to set a minimumFontWidth  otherwhise it may shrink to something quite unreadable according to my test   but this is deprecated and replaced by the later   edit 2    Nevermind  outdated documentation  adjustsFontSizeToFitWidth needs minimumScaleFactor  just be sure no to pass it 0 as a minimumScaleFactor  integer division  10 12 return 0   Small change on the baselineAdjustment value too
