Question

我正在寻找在应用开始时将UIButton's默认titleColor设置为自定义的简单方法。但我想尊重这种情况，titleColor不是默认值并具有自定义值。 [[UIButton appearance] setTitleColor: forState:]允许我一次为所有按钮设置自定义颜色。但是它覆盖了已经设置的自定义颜色。有没有快速方法来覆盖默认标题颜色并同时尊重自定义颜色？

Answer 1

使用appearance设置全局外观（所有按钮）和实例方法 [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];，仅为一个按钮设置颜色。

Answer 2

    Try to this.....

    create catagory class for UIButton like bellow

    Sample.h
    #import <UIKit/UIKit.h>

    @interface Sample : UIButton

    @end

    Sample.m
    #import "Sample.h"

    @implementation Sample
    -(id)initWithCoder:(NSCoder *)aDecoder
    {
        self=[super initWithCoder:aDecoder];
        if (self) {
            [self setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
        }
        return self;
    }
    - (id)initWithFrame:(CGRect)frame
    {
        self = [super initWithFrame:frame];
        if (self) {
            // Initialization code
        }
        return self;
    }

    @end


    and After crate class use this class as Custom Class Like
