我是初学iOS程序员并尝试开发iOS应用程序。我有几个按钮,我放在应用程序的主页上,如图所示。
请看红圈。图像和标题之间没有空格(填充/插入)。
实际上,我已经使用此代码设置了图像和标题插入。但是,它没有给出任何不同的结果。
buttonDoctor.titleLabel?.numberOfLines = 2
buttonDoctor.titleLabel?.lineBreakMode = .byWordWrapping
buttonMedical.titleLabel?.numberOfLines = 2
buttonMedical.titleLabel?.lineBreakMode = .byWordWrapping
buttonQuestion.titleLabel?.numberOfLines = 2
buttonQuestion.titleLabel?.lineBreakMode = .byWordWrapping
buttonLocation.titleLabel?.numberOfLines = 2
buttonLocation.titleLabel?.lineBreakMode = .byWordWrapping
buttonPromotion.titleLabel?.numberOfLines = 2
buttonPromotion.titleLabel?.lineBreakMode = .byWordWrapping
buttonDoctor.image(for: .normal)
buttonMedical.image(for: .normal)
buttonQuestion.image(for: .normal)
buttonLocation.image(for: .normal)
buttonPromotion.image(for: .normal)
//buttonDoctor.titleLabel?.adjustsFontSizeToFitWidth = true
//buttonPromotion.titleLabel?.adjustsFontSizeToFitWidth = true
//buttonLocation.titleLabel?.adjustsFontSizeToFitWidth = true
//buttonQuestion.titleLabel?.adjustsFontSizeToFitWidth = true
//buttonMedical.titleLabel?.adjustsFontSizeToFitWidth = true
let btnimg = try? UIImage(named: "doctorschedule.png")
var newimg = imageResize(image: btnimg!!, scaledTo: CGSize(width: 36, height: 36))
buttonDoctor.setImage(newimg, for: .normal)
buttonDoctor.contentMode = .scaleAspectFit
buttonDoctor.imageEdgeInsets = UIEdgeInsetsMake(5, 3, 0, 5)
buttonDoctor.titleEdgeInsets = UIEdgeInsetsMake(5, 3, 0, 0)
let btnimg2 = try? UIImage(named: "medicalcheck.png")
var newimg2 = imageResize(image: btnimg2!!, scaledTo: CGSize(width: 36, height: 36))
buttonMedical.setImage(newimg2, for: .normal)
buttonMedical.contentMode = .scaleAspectFit
buttonMedical.imageEdgeInsets = UIEdgeInsetsMake(5, 3, 0, 5)
buttonMedical.titleEdgeInsets = UIEdgeInsetsMake(5, 3, 0, 0)
let btnimg3 = try? UIImage(named: "survey.png")
var newimg3 = imageResize(image: btnimg3!!, scaledTo: CGSize(width: 36, height: 36))
buttonQuestion.setImage(newimg3, for: .normal)
buttonQuestion.contentMode = .scaleAspectFit
buttonQuestion.imageEdgeInsets = UIEdgeInsetsMake(5, 3, 0, 5)
buttonQuestion.titleEdgeInsets = UIEdgeInsetsMake(5, 3, 0, 0)
let btnimg4 = try? UIImage(named: "location.png")
var newimg4 = imageResize(image: btnimg4!!, scaledTo: CGSize(width: 36, height: 36))
buttonLocation.setImage(newimg4, for: .normal)
buttonLocation.contentMode = .scaleAspectFit
buttonLocation.imageEdgeInsets = UIEdgeInsetsMake(5, 3, 0, 5)
buttonLocation.titleEdgeInsets = UIEdgeInsetsMake(5, 3, 0, 0)
let btnimg5 = try? UIImage(named: "promotion.png")
var newimg5 = imageResize(image: btnimg5!!, scaledTo: CGSize(width: 36, height: 36))
buttonPromotion.setImage(newimg5, for: .normal)
buttonPromotion.contentMode = .scaleAspectFit
buttonPromotion.imageEdgeInsets = UIEdgeInsetsMake(5, 3, 0, 5)
buttonPromotion.titleEdgeInsets = UIEdgeInsetsMake(5, 3, 0, 0)
我已经为插图尝试了几个值,但它没有给出不同的结果。我的代码有什么问题吗?
请有人帮助我如何解决这个问题。谢谢注意:我还有一个问题。我想在首页的顶部放置一个图像标识(参见橙色圆圈),但我不知道该怎么做。由于没有在导航栏中插入图像的属性。
仅供参考,它是我从故事板(而非UIViewController
)放置的UINavigationController
内的常规导航栏。如果您不介意,请就此提出一些建议。
注意:圆圈中的所有内容都只是普通的UIBUTTON,而不是UIImage和UILabel或UI按钮。请看我的代码。

<强>解决方案:强> 作为查询的解决方案,请将左侧插入设置为10,仅用于标题。将其他插图保持为0(或您想要设置的任何内容)
注意:
试试这个(使用Xcode 9 +):
从storyboard(Interface Builder)设计中,您可以使用UIButton的属性设置插入,如此快照中所示。
答案 1 :(得分:0)
答案 2 :(得分:0)
对于编程解决方案,您正在使用:
dismissButton.titleEdgeInsets = UIEdgeInsets(top: 5, left: 10, bottom: 0, right: 10)
何时应使用:
someButton.contentEdgeInsets = UIEdgeInsets(top: 5, left: 10, bottom: 0, right: 10)
这是因为标题边缘嵌入(根据设计)在为文本调整大小之后是嵌入的。
