How to set UIView frame at runtime using lldb expr (DEBUGGING Console)

Question

I am trying to do the following

(lldb) expr [_tvFeed setFrame:(CGRect)CGRectMake(0, 0, 320, 300)]; 

I get

 error: call to 'CGRectMake' is ambiguous note: candidate function note: candidate function error: 1 errors parsing expression 

I am using Xcode 6.1, LLDB version lldb-320.4.152

Answer 1

Ok so that worked

 expr CGRect rect; rect.origin.x=0; rect.origin.y=0; rect.size.width=320; rect.size.height=300; (void)[_tvFeed setFrame:rect]; 

Answer 2

You can use C compound literals to create a CGRect, because it is just a C struct

It will look like

 (lldb) expr [_tvFeed setFrame:(CGRect){0, 0, 320, 300}]; 

Answer 3

This worked for me:

 (lldb) e (void)[(id)0x7fe38ce039c0 setFrame:(CGRect){0,0,200,300}] (lldb) caflush 

Where 0x7fe38ce039c0 is the identifier of the view I want to print using pviews . You need a chisel for pviews and caflush to work in lldb.

 (lldb) pviews
