如何用swift代码修改ios里text field 里注释文字的颜色深浅
现在的自带文字看不清楚

Answer 1

You can try this:

[textField setValue:[UIColor redColor] forKeyPath:@"_placeholderLabel.textColor"];

But obviously this method is not publicly supported, so it may not be effective in future versions of iOS. To be safe, don't use the default placeHolder, write a label yourself and put it there.
