【IOS實戰】UIButton 設置圖片文字垂直居中排列

大道至簡，直接上代碼

-(void)setButtonContentCenter:(UIButton *) btn

{

    CGSize imgViewSize,titleSize,btnSize;

    UIEdgeInsets imageViewEdge,titleEdge;

    CGFloat heightSpace = 10.0f;

   

    //設置按鈕內邊距

    imgViewSize = btn.imageView.bounds.size;

    titleSize = btn.titleLabel.bounds.size;

    btnSize = btn.bounds.size;

   

    imageViewEdge = UIEdgeInsetsMake(heightSpace,0.0, btnSize.height -imgViewSize.height - heightSpace, - titleSize.width);

    [btn setImageEdgeInsets:imageViewEdge];

    titleEdge = UIEdgeInsetsMake(imgViewSize.height +heightSpace, - imgViewSize.width, 0.0, 0.0);

    [btn setTitleEdgeInsets:titleEdge];

}
