Does the AGSTextSymbol support the text template any more?

Question

Hi,

Earlier version of SDK can set the text content fromw values from the graphic's attributes like below:

AGSTextSymbol *textSymbol = [AGSTextSymbol textSymbolWithTextTemplate:@${pointID} color:[UIColor redColor]];

How to do this in recent version?

Hi, Yue

Yes, the pointID is a field name of a graphic. In the old version of iOS SDK, I can use the property ‘textTemplate’ to set the text symbol text content of a graphic using its attribute field name but not a very string (just like your codes above). That will be very convenient.  This function is very similar with the AGSCalloutTemplate 's titleTemplate.

I just like to know wether the AGSTextSymbol still supports this kind of template function.

Hi Lynn,

I am not really sure what is ${pointID}? Is it point to your database field or something else?

Here are two snippet code to use this AGSTextSymbol textSymbolWith Text method:

NSString *stopString = @"";
  if (stopNumber != NSNotFound) {
  stopString = [NSString stringWithFormat:@%d, stopNumber];
  }
  AGSTextSymbol *ts = [AGSTextSymbol textSymbolWithText:stopString color:[UIColor blackColor]];

Or

NSMutableString *word = [NSMutableString stringWithFormat:@Hello world];
AGSTextSymbol *txtSymbol = [AgSTextSymbol textSymbolWithText:word color:[UIColor redColor]];

Hi, Yue!

I red a document before. It saids the porperty 'text' will replace the porerty 'text template' after v10.2.2.

I tried 'text' porperty with the token like ${pointID}. But it doesn't work.

Did you test this function before? ??

Does it works?

If so , please show me some codes.

Thanks.
