Bubble with random left margin

[chenweiyj]

Hi, all,

I am developing a chat app to support message bubbles appear randomly of the left margin in the table cell. I find that in SOMessageCell, the kBubbleLeftMargin and kBubbleRightMargin are defined as a fixed number. I wonder what is the best way to randomly generate these two values to make the messages appear more interesting. Is it in adjustCell?

Thank you very much!

I think you can do that in -configureMessageCell:forMessageAtIndex method.
Just try to play with origin. x of cell.containerView

Artur,

Thank you for your quick reply.

Because the cell is auto resized according to the message content, how can I calculate the origin.x with the cell width in order to avoid the fact that the left margin is so large that some text is disappeared in the right? What I mean is that how can I also obtain the real cell width according to the message content?

Thank you in advance!

cell.containerView.frame.size.width mast return the bubble's width

Thank you again for your reply.

Now when I put

cell.containerView.frame.origin.x = 100.0;

into -configureMessageCell:forMessageAtIndex method, I have got Expression is not assignable error.

You can't set view.frame.origin.x directly.

CGRect frame = cell.containerView.frame;
frame.origin.x = 100; 
cell.containerView.frame = frame;

Sorry, I followed your direction, but nothing happened.
