Crash with Swift

[francisjervis]

Hi, I get a crash as soon as I tap the tool tip:

tooltip`top_level_code at AppDelegate.swift:

The code I'm using (in a blank project with only this pod installed) is

        let toolTipMgr = JDFSequentialTooltipManager(hostView: self.view)


        toolTipMgr.addTooltipWithTargetView(button, hostView: self.view, tooltipText: "tip", arrowDirection: JDFTooltipViewArrowDirection.Up, width: 180.0)
        toolTipMgr.showNextTooltip()

Hi @francisjervis,

The reason is that you need to keep a strong reference to the tooltip manager.

I just tried it out (in Objective-C); something like this will fix it:

// Interface
@property (nonatomic, strong) JDFSequentialTooltipManager *tooltipManager;

// somewhere else
self.tooltipManager = [[JDFSequentialTooltipManager alloc] initWithHostView:self.view];
[self.tooltipManager addTooltipWithTargetPoint:CGPointMake(100.0f, 200.0f) tooltipText:@"Tooltip" arrowDirection:JDFTooltipViewArrowDirectionUp hostView:self.view width:150.0f];
[self.tooltipManager showNextTooltip];

I should have made this clear in the README - I'll update it to say so.

Joe

Hi, this doesn’t help at all I’m afraid. This isn’t applicable for Swift as far as I know.

So, in Swift you would add a property (let/var, whatever you want) for your tooltip manager to your view controller (I'm assuming it's a view controller where you're using the tooltips from).

Quick/dirty example, that works:

[francisjervis]

Yes, that works, thanks! Not the fix I was expecting (not sure how the “strong reference” translates to declaring as an optional then unwrapping as I don’t know ObjC).

Unfortunately tho when I add

        toolTipMgr?.showsBackdropView = true

the tips don’t appear...

You're right - I'll push a fix when I can.

As a workaround, if you show the tooltips from viewDidAppear instead of viewDidLoad/viewWillAppear, it works ok.

[francisjervis]

Thanks! I’m also seeing some odd layout behaviour (see shots)…it looks like the origin of the tip’s frame = LR corner of the target, which is unexpected with that arrow config.

No pictures have come through...

Hmm I've just tried something similar, and it seems to be working ok. Could you upload a test project showing the issue?
