UIButton子类initWithCoder中的setTitleColor：forState未设置颜色

Question

I have subclassed a UIButton that I have included in a custom .xib file and I am trying to set the title colour for the button via the initWithCoder method for each state. Currently, I have this:

-(id)initWithCoder:(NSCoder *)aDecoder {
  self = [super initWithCoder:aDecoder];
  if(self) {
    self.titleEdgeInsets = UIEdgeInsetsMake(0, 10, 0, 0);
    [self setTitleColor:[UIColor navigationLabelColor] forState:UIControlStateNormal];
  }
  return self;
}

However, the title colour is not changed but the edge insets are. Am I doing something wrong?

PS: I should add, the custom xib is for a different element, but there are several instances of this button in that xib.

Subclassing UIButton is not straight forward due to UIButtonType which seems to default to UIButtonTypeCustom for simple subclassing. Changing the frame/bounds seems to work fine but some other aspects don't.

Personally I have successfully subclassed for my needs which used UIButtonTypeCustom and mainly added background image stretching.

You man need to find another method to accomplish your needs or delve deeper into subclassing UIButton.

Due a search on subclassing UIButton and you will find a substantial amount of information including comments saying that basically not to. See this SO answer .
