使用Userattributes更改UITextField的占位符文本颜色？

Question

I want to change Place holder color from user attributes (interface builder) because i dont want to subclass my UITextfield etc... i searched on internet and found this "_placeholderLabel.textColor" Yes this works well Programmatically [self.tfEmail setValue:[UIColor whiteColor] forKeyPath:@"_placeholderLabel.textColor"]; but i want to use it in user attributes in interface builder.

Answer 1

Try removing '_',

Works for me.

Answer 2

Without USING USER ATTRIBUTES

 self.txtField.attributedPlaceholder = PlaceHolderAttributedString(@"ABCDEF");

where PlaceHolderAttributedString is a macro defined as

 #define PlaceHolderAttributedString(placeHolderText) [[NSAttributedString alloc] initWithString:placeHolderText attributes:@{NSForegroundColorAttributeName:ColorTextFieldPlaceHolder}]

USING USER ATTRIBUTES

 placeholderLabel.textColor 

Answer 3

在swift中：

    one_textfield.setValue(UIColor.redColor(), forKeyPath: "_placeholderLabel.textColor")
