Dies ist, was ich gerade benutze:
Swift 4.2
class TextField: UITextField {
let padding = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
override open func textRect(forBounds bounds: CGRect) -> CGRect {
return bounds.inset(by: padding)
}
override open func placeholderRect(forBounds bounds: CGRect) -> CGRect {
return bounds.inset(by: padding)
}
override open func editingRect(forBounds bounds: CGRect) -> CGRect {
return bounds.inset(by: padding)
}
}
Swift 4
class TextField: UITextField {
let padding = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
override open func textRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
override open func placeholderRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
override open func editingRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
}
Swift 3:
class TextField: UITextField {
let padding = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
override func textRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
override func placeholderRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
override func editingRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
}
Ich habe nie eine andere Polsterung eingestellt, aber Sie können sie anpassen. Diese Klasse kümmert sich nicht um die rechte Ansicht und die linke Ansicht im Textfeld. Wenn Sie möchten, dass das richtig gehandhabt wird, können Sie so etwas wie (Beispiel in objc und ich brauchte nur die richtige Ansicht:
- (CGRect)textRectForBounds:(CGRect)bounds {
CGRect paddedRect = UIEdgeInsetsInsetRect(bounds, self.insets);
if (self.rightViewMode == UITextFieldViewModeAlways || self.rightViewMode == UITextFieldViewModeUnlessEditing) {
return [self adjustRectWithWidthRightView:paddedRect];
}
return paddedRect;
}
- (CGRect)placeholderRectForBounds:(CGRect)bounds {
CGRect paddedRect = UIEdgeInsetsInsetRect(bounds, self.insets);
if (self.rightViewMode == UITextFieldViewModeAlways || self.rightViewMode == UITextFieldViewModeUnlessEditing) {
return [self adjustRectWithWidthRightView:paddedRect];
}
return paddedRect;
}
- (CGRect)editingRectForBounds:(CGRect)bounds {
CGRect paddedRect = UIEdgeInsetsInsetRect(bounds, self.insets);
if (self.rightViewMode == UITextFieldViewModeAlways || self.rightViewMode == UITextFieldViewModeWhileEditing) {
return [self adjustRectWithWidthRightView:paddedRect];
}
return paddedRect;
}
- (CGRect)adjustRectWithWidthRightView:(CGRect)bounds {
CGRect paddedRect = bounds;
paddedRect.size.width -= CGRectGetWidth(self.rightView.frame);
return paddedRect;
}
