Iphone UITextField-更改占位符文本颜色

Question

I'd like to change the color of the placeholder text I set in my UITextField controls, to make it black.

I'd prefer to do this without using normal text as the placeholder and having to override all the methods to imitate the behaviour of a placeholder.

I believe if I override this method:

- (void)drawPlaceholderInRect:(CGRect)rect

then I should be able to do this. But I'm unsure how to access the actual placeholder object from within this method.

You can override drawPlaceholderInRect:(CGRect)rect as such to manually render the placeholder text:

- (void) drawPlaceholderInRect:(CGRect)rect {
    [[UIColor blueColor] setFill];
    [[self placeholder] drawInRect:rect withFont:[UIFont systemFontOfSize:16]];
}
