[Solved] Unable to solve the error “[__NSCFBoolean length]: unrecognized selector sent to instance”

by


Your issue is with this line:

NSURL *U1 =[NSURL URLWithString:[dict objectForKey:@"img"]];

The problem is caused by the fact that you assume:

[dict objectForKey:@"img"]

is returning an NSString when in fact it is returning an NSNumber representing a boolean value.

You need to either figure out why the data in the dictionary is incorrect or you need to use the correct key to get the URL.
