Re: NSTextContainer exclusionPaths not working on iOS without UITextView

2017-09-21 Thread Aki Inoue 
Steve,

You should be rendering using NSLayoutManager instead of -drawInRect:. The 
method is handling NSTextStorage just as a mere NSAttributedString ignoring the 
rest of objects connected.

Check out the documentation for -[NSLayoutManager 
drawGlyphsInGlyphRange:atPoint:].

NSTextContainer exclusionPaths not working on iOS without UITextView

2017-09-21 Thread Steve Mills 
Didn't work the first time I sent this, because something messed up and thought 
the message was too large, when it's less than 2000 characters.

No bites on apple-dev.groups.io, so I'll try here.

I'm trying to use exclusionPaths for the first time and am not having any 
success. For now, I'm just creating the stuff on the fly in my 
drawLayer:inContext: method:. The string draws, but doesn't exclude any path no 
matter what I set it to. I'm also not that familiar with the whole 
NSTextStorage/NSLayoutManager/NSTextContainer family, other than using snippets 
of code in the past, so it could be I'm doing something dumb. Any ideas?

BTW, if I instead install a UITextView and set its exclusionPaths, it works. So 
does NSTextStorage not know enough to draw with the exclusionPaths, and I just 
need to install text views for each one instead?

-(void)drawLayer:(CALayer*)layer inContext:(CGContextRef)ctx
{
if([layer.name isEqualToString:@"balloons"]) {
UIGraphicsPushContext(ctx);

CGRect box = CGRectMake(0, 0, 400, 400);
NSTextStorage* storage = [[NSTextStorage alloc] 
initWithString:@"I like little pigs who run and scurry away from the butcher, 
because the butcher is carrying a large cleaver and wants to chop them up into 
delicious sandwiches!" attributes:@{NSFontAttributeName:[UIFont 
systemFontOfSize:36]}];
UIBezierPath* bez = [UIBezierPath 
bezierPathWithRect:CGRectMake(100, 100, 100, 100)];
NSLayoutManager* lman = [NSLayoutManager new];

[storage addLayoutManager:lman];

NSTextContainer* cont = [[NSTextContainer alloc] 
initWithSize:box.size];

cont.exclusionPaths = @[bez];
[lman addTextContainer:cont];

// Trying different things to see if they make it work - nope.
[lman textContainerChangedGeometry:cont];
[lman invalidateLayoutForCharacterRange:NSMakeRange(0, 
storage.length) actualCharacterRange:nil];

[storage drawInRect:box];

UIGraphicsPopContext();
}
}
