Developer Babak Yaghoobi has released an upgrade to his DPF IOS Component Suite with support for Firemonkey in Delphi 10 Seattle on IOS9. DPF IOS is a collection of platform native controls, a massive library of Objective-C interface code, and a huge number of demos. If you can’t figure out how to do something with Firemonkey on IOS you should check out this component suite. Whether you use these components directly or you just use some of the interface libraries this is a must have component suite to check out. Obviously the components only work on IOS and not Windows, OSX, or Android but they do give you platform native performance on IOS. The trade off is that you lose the universal interface across all platforms. One caveat is that if you use a visual DPF IOS component on your form you can not mix them with FMX components. You can however have FMX and DPF forms within the same application. This new version has expanded TDPFCamera support, and new TDPFLocalAuthentication component, and plenty of bug fixes for good IOS9 compatibility. The component suite is free and open source. You should be able to use it with Appmethod and maybe C++Builder.
Head over and check out the full feature set of the DPF IOS Components for Firemonkey in Delphi 10 Seattle.
