UIButton控件是应用界面中常用的一个控件,用法总结: 一、初始化 UIButton的初始化一般使用其类方法,+ (id)buttonWithType:(UIButtonType)buttonType
//按钮初始化类方法 UIButton *button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];//这里创建一个圆角矩形的按钮 //按钮初始化实例方法...UIButton *button1=[[UIButton alloc]initWithFrame:CGRectMake(50, 300, 200, 50)]; //能够定义的button类型有以下6...是否在dealloc中对UIButton对象进行release操作,取决于UIButton初始化的方式。...如果使用 [[UIButton alloc]init]的方式,则需要主动进行release释放操作。...设置UIButton上字体的颜色设置UIButton上字体的颜色,不是用: [btn.titleLabel setTextColor:[UIColorblackColor]]; btn.titleLabel.textColor
UIButton 的全面解析 建议收藏,用到的时候来这里一查就都明白了 //初始化Button 不用alloca init 的方法 用便利构造器初始化 UIButton *button = [UIButton
textField.borderStyle = UITextBorderStyle.line // textField.clearButtonMode = .whileEditing let btnLeft:UIButton...= UIButton(type:UIButtonType.custom) btnLeft.frame = CGRect(x:0,y:0,width:30,height:30) btnLeft.setBackgroundImage...UIControlState()) textField.leftView = btnLeft textField.leftViewMode = .unlessEditing let btnRight:UIButton...= UIButton(type:UIButtonType.custom) btnRight.frame = CGRect(x:0,y:0,width:30,height:30) textField.rightViewMode...UITextField)-> Bool { textField.resignFirstResponder() return true } func touchupInsideBtnAction(_ btn:UIButton
#import @interface UIButton (MutableTitle) /** * 根据添加的title 改变 button 的长度 * * @...NSString *)text textFont:(UIFont *)textFont forState:(UIControlState)UIControlState; @end #import "UIButton...+MutableTitle.h" @implementation UIButton (MutableTitle) - (void)setMutableTitleWithString:(NSString...maxSize lineBreakMode:NSLineBreakByCharWrapping]; } return textSize; } @end 使用时 导入头文件 #import "UIButton...+MutableTitle.h" UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 100, 40)]; button.center
第一、UIButton的定义 UIButton *button=[[UIButton buttonWithType:(UIButtonType); 能够定义的button类型有以下6种, typedef
设置无限次循环 [animationImageView startAnimating];//开始播放 //[animationImageView stopAnimating];//停止播放 UIButton...但需要实现一个有点击事件的视图的时候,而这个视图内部的布局有需要自定义,这个时候就可以自定义一个UIButton,然后通过addSubview的方式给自定义的Button添加个性化组件和布局。...之前的时候,遇到上面的需求,我都是子类化一个UIView,然后给该子类添加手势,其实只需要子类化一个UIButton即可,这样就不用自己添加手势了!
UIButton 风格 typedef NS_ENUM(NSInteger, UIButtonType) { UIButtonTypeCustom = 0,...UIButtonTypeRoundedRect = UIButtonTypeSystem, // Deprecated, use UIButtonTypeSystem instead }; 简单操作 UIButton...*button = [UIButton buttonWithType:UIButtonTypeSystem]; button.tag = 100; // 给 Button 加入标记 在不同的方法中使用同一个控件...从父类视图中获取button UIButton *btn = (UIButton *)[self.window viewWithTag:100]; ; // 让 Button 失效...; } - (void) buttonAction:(UIButton *)sender { sender.backgroundColor = [UIColor redColor]
先了解Hit-Test请看上一篇文章 https://www.jianshu.com/writer#/notebooks/4989829/notes/33140137 定义一个UIButton的Category...UIButton+ClickRange.h import @interface UIButton (ClickRange) /** 自定义响应边界 UIEdgeInsetsMake...3.0 例如:self.btn.hitHeightScale = 3.0; */ @property(nonatomic, assign) CGFloat hitHeightScale; @end UIButton...+ClickRange.m #import "UIButton+ClickRange.h" #import static const char * kHitEdgeInsets...kHitWidthScale = "hitWidthScale"; static const char * kHitHeightScale = "hitWidthScale"; @implementation UIButton
最近一个项目有获取手机短信跟邮箱验证码功能, 所以要加一个UIButton倒计时功能 例子代码如下: 1 //获取验证码按钮 2 - (IBAction)getButtonClick:(UIButton...*)sender; 3 4 #pragma mark - 获取验证码 5 - (IBAction)getButtonClick:(UIButton *)sender 6 { 7 /...mainColor countColor:countColor]; 12 } 13 14 #pragma mark - button倒计时 15 - (void)setTheCountdownButton:(UIButton
---恢复内容开始--- UIButton 既可以显示图片,又可以显示文字,还能随时调整内部位置 系统自带尺寸 storyboard内部调整UIButton属性 状态 监听按钮点击事件 凡是继承自UIControl...(void)setBackgroundImage:(UIImage *)image forState:(UIControlState)state UI_APPEARANCE_SELECTOR; 自定义UIButton...UIButton内部有两个子控件 UILabel和UIImageView 调整控件内部子控件的frame(两种方式) 实现 titleRectForContentRect 和 imageRectForContentRect...// 设置imageView的内边距(影响到imageView) @property(nonatomic) UIEdgeInsets imageEdgeInsets; 图片拉伸 UIButton

问题:设置渐变后,发现Button上的字体不显示,想着设置方法在layer加载后,测试发现还是不行,把背景颜色的透明度改为0,发现背景色覆盖住字体。
imageView.removeSymbolEffect(ofType: .variableColor.reversing) // imageView.removeAllSymbolEffects() } } UIButton...import UIKit class ViewController: UIViewController { lazy var button1: UIButton = { let...button = UIButton(frame: CGRect(x: 100, y: 0, width: 100, height: 60)) button.setImage(UIImage...button.isSymbolAnimationEnabled = true return button }() lazy var button2: UIButton...UIAction { _ in } actionHandler.image = UIImage(systemName: "plus") let button = UIButton
为了解决这个问题 我们写一个UIButton的Category #import typedef NS_ENUM(NSUInteger,ButtonEdgeInsetsStyle...#import "UIButton+EdgeInsets.h" #import @implementation UIButton (EdgeInsets) - (void...; @property (weak, nonatomic) IBOutlet UIButton *buttonBottom; @property (weak, nonatomic) IBOutlet UIButton...*buttonLeft; @property (weak, nonatomic) IBOutlet UIButton *buttonRight; @property (weak, nonatomic...)

iOS的UIButton是一个非常常见而且常用的控件,我们一般用他来实现某个功能的提交以及选择操作。...两个子视图;而有的人则不会用UIButton来实现图文结合的功能。...那么我们是否要放弃UIButton呢?...答案是否定的,其实UIButton本身是可以支持各种图文结合的,既然UIButton上能同时显示图片和文字,那就可以肯定的说UIButton里面本身一定有一个UIImageView和UILabel8子视图...为了方便大家的使用,我把上面的图文结合样式整理成了一个UIButton的分类方法,大家可以直接拷贝使用: 头文件: // // UIButton+ImageTitleStyle.h //
