Change UITextField’s placeholder color without subclassing it
The safe way to customize UITextField’s placeholder is subclassing the UITextField and overriding placeholderRectForBounds:, Apple won’t bother you on this one. However, if you want to take the risk, you can try this way:
[self.MyTextField setValue:[UIColor darkGrayColor] forKeyPath:@"_placeholderLabel.textColor"];
Use KVC to access/set UITextField’s protected ivar directly, fast and risky.
