IGLDropDownMenu

An iOS drop down menu with pretty animation.

Screenshot

How To Use

Use CocoaPods:

pod 'IGLDropDownMenu'

Manual Install:

Just drap the files in folder IGLDropDownMenu to your project.

####!Try the demo. It's really helpful!

Sample Code

  1. Create your IGLDropDownItem array and set up

    NSMutableArray *dropdownItems = [[NSMutableArray alloc] init];
IGLDropDownItem *item = [[IGLDropDownItem alloc] init];
[item setIconImage:[UIImage imageNamed:@"icon.png"]];
[item setText:@"title"];
[dropdownItems addObject:item];

  2. Create your IGLDropDownMenu and set the up the parameter name dropDownItems

    IGLDropDownMenu *dropDownMenu = [[IGLDropDownMenu alloc] init];
[dropDownMenu setFrame:CGRectMake(0, 0, 200, 45)];
dropDownMenu.menuText = @"Choose Weather";
dropDownMenu.menuIconImage = [UIImage imageNamed:@"chooserIcon.png"];
dropDownMenu.paddingLeft = 15;  // padding left for the content of the button

  3. modify the params of IGLDropDownMenu

    dropDownMenu.type = IGLDropDownMenuTypeStack;
dropDownMenu.gutterY = 5;
dropDownMenu.itemAnimationDelay = 0.1;
dropDownMenu.rotate = IGLDropDownMenuRotateRandom;

  4. Call the reloadView method (Very Important!)

    // every time you change the params you should call reloadView method
[dropDownMenu reloadView];

Parameters

These are just some of the parameters you can use, you can find more(or make more) in the code.

####For IGLDropDownMenu

  • animationDuration set the duration(s) of the animation in second

  • animationOption set the UIViewAnimationOptions for the animation

  • itemAnimationDelay set the delay(s) before each of item start to animate

  • direction set the direction when the menu expand

  • IGLDropDownMenuRotateLeft rotate to left on expand
  • IGLDropDownMenuRotateRight rotate to right on expand
  • IGLDropDownMenuRotateRandom rotate random on expand every single time
  • type set the menu type (remember when you set the type to SlidingIn* you can't have the rotate type at the same time.)
  • IGLDropDownMenuTypeNormal default value, item will hide behind the menu button on fold
  • IGLDropDownMenuTypeStack item will hide behind the menu button and make a stack like look
  • IGLDropDownMenuTypeSlidingInBoth item will slide in and out from both sides
  • IGLDropDownMenuTypeSlidingInFromLeft item will slide in from left
  • IGLDropDownMenuTypeSlidingInFromRight item will slide in from right
  • IGLDropDownMenuTypeFlipVertical item will flip vertical
  • IGLDropDownMenuTypeFlipFromLeft item will flip from left
  • IGLDropDownMenuTypeFlipFromRight item will flip from right
  • slidingInOffset set the offset value for the items slide in and out
  • gutterY set the Y gutter between items
  • alphaOnFold set the item alpha value when menu on fold, only use this when the style won't fit your mind
  • flipWhenToggleView when you set this to true, the menu button will flip up when you click
  • useSpringAnimation use the spring animation for iOS7 or higher version, default is true
  • menuButtonStatic keeps the menu button static regardless of selected menu item, default is NO

####For IGLDropDownItem

  • iconImage set the icon image for the item
  • text set the text string for the item
  • textLabel for you to adjust the text label style
  • object you can store your custom item in this property
  • index the item index
  • paddingLeft the left padding of the image view or only text
  • showBackgroundShadow you can hide the drop down shadow with this property
  • backgroundColor you can change the background color with this property

Remember the menuButton in IGLDropDownMenu is also an IGLDropDownItem.

CustomView

If you want to control the view by yourself, you can use the initWithMenuButtonCustomView of IGLDropDownMenu and initWithCustomView of IGLDropDownItem. If you use customView, the customView will auto set userInteractionEnabled = NO and the menu menuButtonStatic = YES and some style parameters will be invalid. You need to handle it yourself. I make a customView in the demo, try it!

Delegate

####For IGLDropDownMenu

  • - (void)dropDownMenu:(IGLDropDownMenu*)dropDownMenu selectedItemAtIndex:(NSInteger)index;
  • - (void)dropDownMenu:(IGLDropDownMenu *)dropDownMenu expandingChanged:(BOOL)isExpending;

Requirements

  • target platform: >=iOS 6.0 (I never test the version below 6.0, maybe you can make some try and tell me.)
  • ARC

Thanks

This drop-down menu idea is come from here, I found this demo one day and just implement it on iOS.
