如果对于UIButton中的titleEdgeInsets和imageEdgeInsets不是很明白的，先参考：//www.greatytc.com/p/1f1c9dada4dd

二话不说，直接上代码
.h文件

typedef enum {
    UIButtonTitleWithImageAlignmentUp = 0,  // image is up, title is down
    UIButtonTitleWithImageAlignmentLeft,    // image is left, title is right
    UIButtonTitleWithImageAlignmentDown,    // image is down, title is up
    UIButtonTitleWithImageAlignmentRight    // image is right, title is left
} UIButtonTitleWithImageAlignment;


@interface EYImgTextButton : UIButton


@property (nonatomic) CGFloat imgTextDistance;  //  image and title的之间的Distance,

@property(nonatomic,assign)UIButtonTitleWithImageAlignment buttonTitleWithImageAlignment;

@end

.m文件

- (instancetype)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        
        _imgTextDistance=5;
        _buttonTitleWithImageAlignment=UIButtonTitleWithImageAlignmentLeft;
        //default Alignment is in order to facilitate the layout
        [self setContentHorizontalAlignment:UIControlContentHorizontalAlignmentLeft];
        [self setContentVerticalAlignment:UIControlContentVerticalAlignmentTop];
    }
    return self;

        imgOffsetX = interval;

        titleOffsetX = buttonWidth - (imgWidth + textWitdh + interval);
        titleOffsetY = (buttonHeight - textHeight) / 2;
    }else if (_buttonTitleWithImageAlignment == UIButtonTitleWithImageAlignmentDown) {
        interval = (buttonHeight - (imgHeight + _imgTextDistance + textHeight)) / 2;

        imgOffsetX = interval + textWitdh + _imgTextDistance;
        imgOffsetY = (buttonHeight - imgHeight) / 2;
        titleOffsetX = - (imgWidth - interval);
        titleOffsetY = (buttonHeight - textHeight) / 2;
    }
    [self setImageEdgeInsets:UIEdgeInsetsMake(imgOffsetY, imgOffsetX, 0, 0)];
    [self setTitleEdgeInsets:UIEdgeInsetsMake(titleOffsetY, titleOffsetX, 0, 0)];
    
}

直接拿过来就能用，支持masonry
