【實用書籍app】idev101: Fonts, Colors & UI Sizes|最夯免費app

Here are several useful tools and resources for iOS developers, including a color picker, complete font list and type tester, printable app design templates, an interactive app submission checklist, and more.

Fonts & Type Tester:

• The complete list of all the fonts on your device, plus the System fonts

• Type tester: see a preview of your text in that font, the line height (in points) for that font, the frame size, and the actual font name to use in your UIFont declarations

• Sample code shows you how to specify a font, how to use system fonts, how to get the size of a string in a particular font, and how to use custom fonts in an app

Color Picker:

• Color sliders for both RGB and HSB color modes. In RGB mode, the slider also shows the numeric value between 0 and 255.

• The selected color is displayed in the sample box, along with its CSS hex color value. You can also enter a CSS hex color value and get the corresponding RGB or HSB values

• Shows you the actual code for creating a UIColor object with the selected color

• Sample code shows you how to set colors and transparent backgrounds, plus a list (and preview) of all the standard UIColors (e.g. [UIColor blueColor])

UI Sizes:

• Screen and UI element sizes for iPhone 4S (and earlier), iPhone 5, and iPad screens

• Icon sizes for iPhone, iPad, and Web app icons

• Keyboard sizes for the on-screen (English) keyboards, plus how to get the (language-independent) keyboard size programmatically, and how to slide the view up so the keyboard doesn't overlap the text input box

• Default (launch) image sizes

• Screen shot sizes (required for app submission)

Extras:

• Interactive checklist for preparing and submitting your app to iTunes Connect

• Printable PDF templates for designing your app - includes 10 different iPhone templates in both portrait and landscape.

Currently this app is optimized for the iPhone. A universal (iPad-friendly) version will be available in a future update.
