ios - TTTAttributedLabel not displaying the last line when having Emoji symbols -


we using "tttattributedlabel" displaying labels. calculating correct rectangle size, use nsstring's "sizewithfont" method, "constrainedtosize" width of field.
calculation fine, unless there emoji symbols in text, , text multi line (for example: smiley-newline-smiley). in case, returned size small (vertically), , last line not shown. if text not contain emoji (e.g. x-newline-x) - size correct.
our font "helveticaneue" size:16.25, in case makes difference.
there better way calculate needed size, work emoji well?
thanks

i had same situation when making auto-height label according contents of label. seems fine, except when there emojis in label content.

it because did't use correct settext method attributedstring.

[label settext:text afterinheritinglabelattributesandconfiguringwithblock:^      return mutableattributedstring; }];

this correct way set attributedstring, did 

[label setattributedtext:text];

so getting wrong label heights when includes emojis in it.

i solved problem changing set method correct 1 described in github manual.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
