ios – UIButton Padding

概述UIButton是否有相同的填充,就像在CSS中一样？ 我似乎有小按钮的问题,所以我想扩展按钮大小,以便轻松点击. 我围绕代码调整了UIButton的大小并使内容保持原样： - (void)adjustButtonView:(UIButton *)button toSize:(CGSize)size{ CGRect previousFrame = button.frame; CG UIbutton是否有相同的填充,就像在CSS中一样？

我似乎有小按钮的问题,所以我想扩展按钮大小,以便轻松点击.

我围绕代码调整了UIbutton的大小并使内容保持原样：

- (voID)adjustbuttonVIEw:(UIbutton *)button toSize:(CGSize)size{    CGRect prevIoUsFrame = button.frame;    CGRect newFrame = button.frame;    newFrame.size = size;    CGfloat adjustX = (size.wIDth - prevIoUsFrame.size.wIDth)/2;    CGfloat adjustY = (size.height - prevIoUsFrame.size.height)/2;    newFrame.origin.x = prevIoUsFrame.origin.x - adjustX;    newFrame.origin.y = prevIoUsFrame.origin.y - adjustY;    button.frame = newFrame;    UIEdgeInsets edgeInsets = UIEdgeInsetsMake(adjustY,adjustX,adjustY,adjustX);    button.contentEdgeInsets = edgeInsets;}

我只是想知道是否有更简单的方法来扩展UIbutton.

解决方法 我认为这比你做的更简单.但是我们可以通过将方法移动到UIbutton类别来使代码更好.

UIbutton Resize.h

@interface UIbutton (Resize)- (voID)adjustToSize:(CGSize)size;@end

UIbutton Resize.m

@implementation UIbutton (Resize)- (voID)adjustToSize:(CGSize)size{    CGRect prevIoUsFrame = self.frame;    CGRect newFrame = self.frame;    newFrame.size = size;    CGfloat adjustX = (size.wIDth - prevIoUsFrame.size.wIDth)/2;    CGfloat adjustY = (size.height - prevIoUsFrame.size.height)/2;    newFrame.origin.x = prevIoUsFrame.origin.x - adjustX;    newFrame.origin.y = prevIoUsFrame.origin.y - adjustY;    self.frame = newFrame;    UIEdgeInsets edgeInsets = UIEdgeInsetsMake(adjustY,adjustX);    self.contentEdgeInsets = edgeInsets;}@end
