iOS 自定义键盘字母按钮
最近项目有个需求24个按钮, 排列像键盘一样,获取字母进行索引搜索单词, 那就for循环添加 按钮吧, 这是封装的view, 在这里记录一下, 可以直接复制代码效果图
:
.h 里有个block 可以回调点击的是哪个单词这里床的是字符串
#import
@interfaceTKYKeyboardView :UIView
@property(nonatomic,copy)void(^seachLetterStrbBlock)(NSString* letterStr);
@end
.m中具体思路是创建三个view, 第一行是一个view 第二行是一个view, 第三行字母也是一个view,然后for循环 添加字母按钮
#import "TKYKeyboardView.h"
#import "UIView+Extension.h"
@interface TKYKeyboardView()
@property (nonatomic, strong)NSMutableArray *arrM;
@property (nonatomic, strong)UIButton *button;
@end
@implementationTKYKeyboardView
