Using makeObjectsPerformSelector:withObject: with a false boolean

Question

I\'ve got an array of UITextField objects called _fields. I want to be able to message them all at once to set them to be highlighted,

Answer 1

You should try using blocks because setHighlighted takes a BOOL as a parameter and not a pointer (NSNumber *) :

[fields enumerateObjectsUsingBlock:^(UITextField *obj, NSUInteger idx, BOOL *stop) {
    obj.highlighted = YES; // or NO
}];
