comparing UIButton title

s7162 · 05-16-2011, 06:50 AM

Hey guys,

i wanna compare the title for a UIButton, but the method im using is clearly wrong, as it isn't working, -

Code:

if ([randomButton.titleLabel isEqual:@"Random"]){
//do something
}

So, my question is, what is the correct method to do this?

thanks!

thanks for the reply, heres what i got

Code:

first i get a warning,

Code:

'UILabel' may not respond to 'isEqualToString'

if i ignore it and run anyways, i get'

Code:

thread 1: program received signal: "SIGBRT"

Code:

** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIButtonLabel isEqualToString:]: unrecognized selector sent to instance 0x5c41120'

do like this

Code:

NSString *temp=@"Random";
 if ([temp isEqualToString:randomViewButton.titleLabel]){
 //something
}

this will crash for the same motive...you are trying to call isEqualToString with a UILabel

look on the left of the screen where the line numbers are. You will see a little blue arrow pointing to your code on the EXACT line that it "crashes" on. Click on that little blue arrow and drag it away as if you were removing it from your dock, then run again. Search for Xcode breakpoints on google if you are still perplexed

FYI this is not a crash, is just a breakpoint (a line of code where you decide to pause the running of your code for debugging purpose)
