UILabel text margin [duplicate]

Answer 1

I didn't find the suggestion to use UIButton in the answers above. So I will try to prove that this is a good choice.

button.contentEdgeInsets = UIEdgeInsets(top: 0, left: 8, bottom: 0, right: 8)

In my situation using UIButton was the best solution because:

• I had a simple single-line text
• I didn't want to use UIView as a container for UILabel (i.e. I wanted to simplify math calculations for Autolayout in my cell)
• I didn't want to use NSParagraphStyle (because tailIndent works incorrect with Autolayout – width of UILabel is smaller than expected)
• I didn't want to use UITextView (because of possible side effects)
• I didn't want to subclass UILabel (less code fewer bugs)

That's why using the contentEdgeInsets from UIButton in my situation became the easiest way to add text margins.

Hope this will help someone.

In Swift it solves like this.

class Label: UILabel {
    override func drawTextInRect(rect: CGRect) {
        super.drawTextInRect(UIEdgeInsetsInsetRect(rect, UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 10)))
    }
}

I think UILabel class have no method for setting margin. Why you not set the position of Label at required place?

See below code:

UILabel *label = [[UILabel alloc] init];
label.text = @"This is label";
label.frame = CGRectMake(0,0,100,100);

if from interface builder then just position Label by following:

yourLabel.frame = CGRectMake(0,0,100,100);

Answer 4

The best approach to add padding to a UILabel is to subclass UILabel and add an edgeInsets property. You then set the desired insets and the label will be drawn accordingly.

OSLabel.h

#import <UIKit/UIKit.h>

@interface OSLabel : UILabel

@property (nonatomic, assign) UIEdgeInsets edgeInsets;

@end

OSLabel.m

#import "OSLabel.h"

@implementation OSLabel

- (id)initWithFrame:(CGRect)frame{
    self = [super initWithFrame:frame];
    if (self) {
        self.edgeInsets = UIEdgeInsetsMake(0, 0, 0, 0);
    }
    return self;
}

- (void)drawTextInRect:(CGRect)rect {
    [super drawTextInRect:UIEdgeInsetsInsetRect(rect, self.edgeInsets)];
}

- (CGSize)intrinsicContentSize
{
    CGSize size = [super intrinsicContentSize];
    size.width  += self.edgeInsets.left + self.edgeInsets.right;
    size.height += self.edgeInsets.top + self.edgeInsets.bottom;
    return size;
}

@end

Here is a swift solution. Just add this custom class on the bottom of your file (or create a new file for it) and use MyLabel instead of UILabel when creating your label.

class MyLabel: UILabel{
    override func drawTextInRect(rect: CGRect) {
        super.drawTextInRect(UIEdgeInsetsInsetRect(rect, UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 0)))
    }
}

without subclassing and all that jazz.. i did this dynamically:

[cell.textLabel setTranslatesAutoresizingMaskIntoConstraints:NO];
[cell.textLabel constraintTrailingEqualTo:cell.contentView constant:-100];

the constraint part is just a simple code sugar wrapper (we have the same methods for adding a padding from top/bottom/left/right).. i'll open source the whole wrapper if i get enough love here:

- (id)constraintTrailingEqualTo:(UIView *)toView constant:(CGFloat)constant
{
    NSLayoutConstraint *cn = [NSLayoutConstraint constraintWithItem:self
                                                          attribute:NSLayoutAttributeTrailing
                                                          relatedBy:NSLayoutRelationEqual
                                                             toItem:toView
                                                          attribute:NSLayoutAttributeTrailing
                                                         multiplier:1 constant:constant];

    [toView addConstraint:cn];
    return self;
}

(note i did this in the context of

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath;

you may have to call [self setNeedsLayout]; depending on your context.
