AutoLayout和CATextLayer iOS7

Question

I'm trying to animate text changing with CATextLayer.

   intValueLayer = [CATextLayer layer];
   [intValueLayer setFrame:self.lblIntPart.bounds];
   [[self.lblIntPart layer] addSublayer:intValueLayer];

I'm using AutoLayout on my view and I know that setFrame method not working properly. In my case frame of CATextLayer smaller than self.lblIntPart .So, how can I add constraints to my TextLayer or display it with the same frame as self.llbIntPart.

Thank you!

All method looks like:

   intValueLayer = [CATextLayer layer];
    [intValueLayer setFrame:self.lblIntPart.bounds];
    [[self.lblIntPart layer] addSublayer:intValueLayer];

    [intValueLayer setAlignmentMode:@"center"];
    [intValueLayer setForegroundColor:self.category.colour.colour.CGColor];
    [intValueLayer setFont:CFBridgingRetain(@"DilleniaUPCBold")];
    [intValueLayer setFontSize:96.0f * scale];
    intValueLayer.contentsScale = [UIScreen mainScreen].scale;

    [intValueLayer setString:@"0"];

After trying to reproduce your issue, here is what I understand.

Probably your Label frame is big, and the default CATextLayer font properties don't fit the frame completely.

Try adjusting CATextLayer's properties.

[intValueLayer setFont:(__bridge CFTypeRef)([UIFont systemFontOfSize:17])];
[intValueLayer setFontSize:17];

so that it matches the properties if you had used label as is.
