Tooltip bubble with text in it used to display tips for UI elements, with a pointed arrow (to refer to the UI element).

The tooltip fades in and will automatically fade out. See displayDuration.

Superclass:	`UIView`
Declared in:	`FBSDKTooltipView.h`

属性

colorStyle

Gets or sets the color style after initialization.

@property (nonatomic,
    assign) FBSDKTooltipColorStyle colorStyle;

Discussion:

Defaults to value passed to -initWithTagline:message:colorStyle:.

声明语言： FBSDKTooltipView.h

displayDuration

Gets or sets the amount of time in seconds the tooltip should be displayed.

@property (nonatomic,
    assign) CFTimeInterval displayDuration;

Discussion:

Set this to zero to make the display permanent until explicitly dismissed. Defaults to six seconds.

声明语言： FBSDKTooltipView.h

message

Gets or sets the message.

@property (nonatomic,
    copy) NSString *message;

声明语言： FBSDKTooltipView.h

tagline

Gets or sets the optional phrase that comprises the first part of the label (and is highlighted differently).

@property (nonatomic,
    copy) NSString *tagline;

声明语言： FBSDKTooltipView.h

实例方法

dismiss

Remove tooltip manually.

- (void) dismiss;

Discussion:

Calling this method isn't necessary - tooltip will dismiss itself automatically after the displayDuration.

声明语言： FBSDKTooltipView.h

initWithTagline:message:colorStyle:

Designated initializer.

参数	描述
`tagline`	First part of the label, that will be highlighted with different color. Can be nil.
`message`	Main message to display.
`colorStyle`	Color style to use for tooltip.

- (instancetype)

`initWithTagline:`	`(NSString *)tagline`
`message:`	`(NSString *)message`
`colorStyle:`	`(FBSDKTooltipColorStyle)colorStyle;`

Discussion:

If you need to show a tooltip for login, consider using the FBSDKLoginTooltipView view.

声明语言： FBSDKTooltipView.h

presentFromView:

Show tooltip at the top or at the bottom of given view. Tooltip will be added to anchorView.window.rootViewController.view

参数	描述
`anchorView`	View to show at, must be already added to window view hierarchy, in order to decide where tooltip will be shown. (If there's not enough space at the top of the anchorView in window bounds - tooltip will be shown at the bottom of it)

- (void) presentFromView:(UIView *)anchorView;

Discussion:

Use this method to present the tooltip with automatic positioning or use -presentInView:withArrowPosition:direction: for manual positioning If anchorView is nil or has no window - this method does nothing.

声明语言： FBSDKTooltipView.h

presentInView:withArrowPosition:direction:

Adds tooltip to given view, with given position and arrow direction.

参数	描述
`view`	View to be used as superview.
`arrowPosition`	Point in view's cordinates, where arrow will be pointing
`arrowDirection`	Whenever arrow should be pointing up (message bubble is below the arrow) or down (message bubble is above the arrow).

- (void)

`presentInView:`	`(UIView *)view`
`withArrowPosition:`	`(CGPoint)arrowPosition`
`direction:`	`(FBSDKTooltipViewArrowDirection)arrowDirection;`
