T1Autograph

The Autograph iOS library has been updated to v1.6.5 (build 37). One day we’ll issue a "Signature Edition" of T1Autograph because it’s a bad pun, and also the limit of our wit. Today is not that day. This update simply adds a choice for how to handle the Apple Pencil, fixes a few issues, and tidies up for iOS 10. Oh! One more thing. T1Autograph is now available as a dynamic framework. This is simpler to integrate (especially with swift projects (no more bridging header!)). We intend to move completely away from static library releases soon, but this time you can choose which style to work with. The static library is compatible back to iOS 6. The framework requires at least iOS 8. Thanks again for using T1Autograph. We hope it continues to be of good service to you. Show release notes

  • New
    • T1Autograph property drawOnlyWithApplePencil prevents finger touches from drawing. The palm rejection with Apple Pencil is already quite good, so this setting is off by default.
  • Fixed
    • Leak eliminated when the signature is created.
    • Note: iOS 10 may throw some log messages about +/- infinity when the signature completes. This is a seemingly harmless iOS bug related to color handling in quartz drawing contexts. We expect the log message to be suppressed or eliminated in a later iOS 10 point release.

Note: if you’re using CocoaPods, your podfile should show something similar to:

pod 'T1Autograph', '~> 1.6'

A final note about dynamic frameworks: The App Store currently rejects apps containing simulator binary slices. T1Autograph (and most other frameworks) include these slices so you can work in the simulator. There’s a handy script available to trim down any frameworks you might be using at build time.

T1Autograph

The Autograph iOS library has been updated to v1.6.3 (build 35) to support iPhone’s spiffy new 3D Touch and iPad Pro's Pencil. So how is this pressure data used? While accepting a signature, pressure and pen velocity are blended to produce a natural, realistic representation. The overall result is subtle and pleasing, and we’ve worked to ensure consistent results between newer devices and those without pressure capability. Beyond that, the library returns 3 additional properties for each point in the signature. They are pressure, azimuthAngle, and altitudeAngle. The last two are available when a signature is created with an Apple Pencil. Show release notes

  • New
    • T1SignaturePoint now reports pressure, azimuthAngle, and altitudeAngle when available.
  • Fixed
    • Irregular stroke width terminations when drawing using a mouse in the simulator.

Note: if you’re using CocoaPods, your podfile should show something similar to:

pod 'T1Autograph', '~> 1.6'

T1Autograph

The Autograph iOS library has been updated to v1.6.2 (build 34) with support for iOS 9. Please note: This release includes LLVM bitcode embedded within the binary, and will therefore cause linker errors in Xcode versions lower than 7. If you must use Xcode 6, you can download a special build with bitcode stripped out here. Show release notes

  • New
    • Updated lock symbol when including a crypto hash watermark on the signature
    • Added preliminary groundwork for pressure-sensitive screens. We plan to fully implement pressure sensitivity after the release of new Apple devices in September. At that time, the T1SignaturePoint class will have a non-zero pressure property on supported devices.
    • Removed debug symbols for a streamlined binary size.
    • Added LLVM bitcode support.
  • Fixed
    • Crash in iOS 9 caused by unretained png data.
    • Updated T1Autograph.h usage instructions and T1Signature.h description of raw points.

Note: if you’re using CocoaPods, your podfile should show something similar to:

pod 'T1Autograph', '~> 1.6.2'

T1Autograph

Our Autograph iOS library has been update to v1.6.1 (build 31) with a fix for auto layout. Show release notes

  • Fix
    • Drawing canvas is now correctly updated after the canvas frame is updated by the auto layout engine. Thanks to Lucien.

Note: if you’re using CocoaPods, your podfile should show something similar to:

pod 'T1Autograph', '~> 1.6.1'

T1Autograph

Our Autograph iOS library has had an exciting upgrade to v1.6.0 (build 30). Show release notes

  • Add
    • In addition to PNG format, a T1Signature now includes a PDF document reference and raw PDF data. As this is a vector format, it can be displayed crisply at any resolution. The T1AutographDemo application has been updated with sample code showing you how to use this new format.
    • All images are now removed from T1Autograph. Thanks to PaintCode, you can now delete the t1_logo.png and autograph_x.png images from your project. Images are entirely rendered by drawing code.
    • There’s a new delegate method perfect for grabbing and displaying signature data before the built-in modal view has finished closing. It’s called autograph:willCompleteWithSignature:.
    • Support for iOS 8. The previous version worked well when licensed, but the watermarking feature could fail. A few other settings were slightly tweaked. Note that this release still supports iOS 5 and above, and includes all the necessary 32- and 64-bit binaries.
  • Fix
    • Drawing canvas is now updated after changing the strokeColor property. Thanks to Ignacio.

Note: if you’re using CocoaPods, make sure your podfile enables this new version. It should show something similar to:

pod 'T1Autograph', '~> 1.6.0'

Version 1.6.0 is a free upgrade for all current T1Autograph licensees. If this library has been helpful for you, we’d really appreciate a recommendation or tweet to help us spread the word.
