Changing UITextField Placeholder font

Objective-C:

UIColor *color = [UIColor blackColor];    someUITextField.attributedPlaceholder =  [[NSAttributedString alloc] initWithString:@"Placeholder Text"    attributes:@{       NSForegroundColorAttributeName: color,       NSFontAttributeName : [UIFont fontWithName:@"Roboto-Bold" size:17.0]    }  ];

(There are no brackets between literal dictionary key-value pairs.)

Swift:

let attributes = [    NSForegroundColorAttributeName: UIColor.blackColor(),    NSFontAttributeName : UIFont(name: "Roboto-Bold", size: 17)! // Note the !]someUITextField.attributedPlaceholder = NSAttributedString(string: "Placeholder Text", attributes:attributes)

Update for Swift 4.x:

textField.attributedPlaceholder = NSAttributedString(string: "Placeholder Text", attributes: [    .foregroundColor: UIColor.lightGray,    .font: UIFont.boldSystemFont(ofSize: 14.0)])

For the convenience of swift people:

someTextField.attributedPlaceholder = NSAttributedString(string: "someString", attributes:[NSForegroundColorAttributeName: UIColor.lightGrayColor(), NSFontAttributeName: PlaceHolderFont])
