A lightweight replacement for Apple's UILabel

Hi there I'm Mike🔴 👋

I'm a developer who specialises in native mobile apps for iOS and Android (in that order) which live on the intersection of physical and digital worlds. I work at Intent where I manage one of the mobile engineering teams.

Tools I use during work

iOS 📱	Android 🤖	IoT 🦾
Swift	Kotlin	Arduino
SwiftUI	Jetpack Compose	Raspberry Pi
CoreBluetooth	Android Auto	Espressif
CarPlay		BlueZ

I'm also one of those dinasours who worked with Objective-C and UIKit and XML-based Android views.

Some of the stuff I created:

• MTLabel Back in the day, UILabel was pretty limited so I rewrote it with some fireworks
• Base64Stream You have a large base64 encoded file? Convert it to a stream instead!
• AndroidAr I used to do some AR stuff on Android a while back before ARCore. I shared some of the code I used to make future devs life a little easier.

Hackatons

I love taking part in Hackatons. I also managed to win some of them. I'm also a cohost of a podcast which is entirely focused for hackatons: The HackathonShow. Quite recently, I've won HackYeah 2023 cybersecurity task

I occasionally speak at conferences such as:

• Pozitiv Tech 2022 🇵🇱
• Mobilization - Android Persistence 2012 🇵🇱
• Mobilization - Objective-C Runtime 2013 🇵🇱
• Droidcon.nl NFC on Android 🇳🇱

mtlabel's Issues

Compatibility with Arabic language

Hi.
Your MTLabel is perfect for me, because I can adjust the line height with it.

Arabic (especially when used to write poetry or religious texts) has little symbols which modify the pronunciation, these little symbols are a main part of the written language!

The arabic fonts require a larger height of lines, because these symbols are placed above and underneath the text.

But there are two problems that come along with these facts....

• Arabic text direction is right to left - MTLabel needs to be adjusted in a way that the alignment is set correct => right side.
• Modifying the line height bears one problem, one cannot calculate the dimension of the text with NSString sizeWithFont anymore. It would be perfect if MTLabel could provide an own sizeWithFont feature that considers the modified line height

Thank you very much for your efforts,
Bilal

Please add semantic version tags

I’ve recently added MTLabel to the CocoaPods package manager repo.

CocoaPods is a tool for managing dependencies for OSX and iOS Xcode projects and provides a central repository for iOS/OSX libraries. This makes adding libraries to a project and updating them extremely easy and it will help users to resolve dependencies of the libraries they use.

However, MTLabel doesn't have any version tags. I’ve added the current HEAD as version 0.0.1, but a version tag will make dependency resolution much easier.

Semantic version tags (instead of plain commit hashes/revisions) allow for resolution of cross-dependencies.

In case you didn’t know this yet; you can tag the current HEAD as, for instance, version 1.0.0, like so:

$ git tag -a 1.0.0 -m "Tag release 1.0.0"
$ git push --tags

How to add 'UIMenuController'

Wording: fontColor -> textColor

UIKit uses textColor and not fontColor. I guess it makes sense to stick with known naming conventions.

How to get the label height after ResizeToFitText?

Hi guys,

here is my code

MTLabel *label3 = [MTLabel labelWithFrame:CGRectMake(20, 240, 250, 1) 
                                  andText:@"This label was resized to fit text inside it"];
[label3 setTextAlignment:MTLabelTextAlignmentCenter];
[label3 setFont:[UIFont systemFontOfSize:20]];
[label3 setResizeToFitText:YES];
NSLog(@"%f", label3.frame.size.height);
[self.view addSubview:label3];

I want to get the label frame size , but the value of NSLog output is always 1.000000
How i get the label frame size after resize ?

Thanks guys.

Vertical Alignment

There seems to be no way to vertically align a label. For example, if you declare a 2 line label, but the label only turns out to be 1 line, I would need it to be vertically centered instead of align-top.

Blurry text with custom color

Interesting issue. If I use any of the standard colors (ie [UIColor blackColor]) I get crisp, good looking text. However, using an RGB color (ie [UIColor colorWithRed:49/255.0f green:54/255.0f blue:57/255.0f alpha:1]) causes blurry text:

Example:

limitToNumberOfLines issue

Just replace the code at line 417---422 in MTLabel.m file with following code
//Check to see if our index didn't exceed the text, and if should limit to number of lines
if ((currentIndex + lineLength >= [_text length]) ||
(_limitToNumberOfLines && count >= _numberOfLines-1)) {
shouldDrawAlong = NO;

    }

ld linker error

I'm working on a project that already uses CoreText and I'm getting a nasty ld linker error in Xcode 4 when I add the header and implementation files. They look like this:

ld: duplicate symbol _CTLineGetTypographicBoundsAsRect in /Users/dylan/Library/Developer/Xcode/DerivedData/unstuck-aqkbmvbxmfrwxcflssycdwtilkfl/Build/Intermediates/unstuck.build/Debug-iphonesimulator/unstuck.build/Objects-normal/i386/MTLabel.o and /Users/dylan/Library/Developer/Xcode/DerivedData/unstuck-aqkbmvbxmfrwxcflssycdwtilkfl/Build/Intermediates/unstuck.build/Debug-iphonesimulator/unstuck.build/Objects-normal/i386/OHAttributedLabel.o for architecture i386
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/clang failed with exit code 1

Any thoughts?

How to get the text height?

I have a bunch of UILabels in a scrollview. I just replaced them with these, how do i get the height of the text?

This works for normal labels:

static CGFloat getLabelHeight(MTLabel *label, CGFloat width)
{
    CGSize size = [[label text] sizeWithFont: [label font]
                           constrainedToSize: CGSizeMake(width,CGFLOAT_MAX)
                               lineBreakMode: UILineBreakModeWordWrap];
    return size.height;
}

Readme not accurate about UILabel

"UILabel forces you to specify number of lines"
This is not true (anymore?)
Setting the line number to 0 will allow unlimited number of lines.

Great project anyway :)

How to customize line spacing

Love the library. The one feature I am looking for however is how to customize the line spacing between label lines.
Does that feature exist with this library?
I couldn't find it in the API.
i.e. I would like to sent the spacing between lines on a label to 4px.
How would I do that?

Many thx.

setResizeToFitText does not work

Hi guys!

I can't make setResizeToFitText work.

I'm pasting in the code from the documentation, and that does not seem to work either.
What am I doing wrong?

Thanks,
Gon

MTLabel *label = [MTLabel labelWithFrame:CGRectMake(20, 150, 250, 70)
andText:@"Hello!"];
[label setTextAlignment:MTLabelTextAlignmentCenter];
[label setFont:[UIFont boldSystemFontOfSize:15]];
[label setFontColor:[UIColor blueColor]];
[label setLineHeight:20];
[label setResizeToFitText:YES];
[self.view addSubview:label];
