最近項目有個需求24個按鈕, 排列像鍵盤一樣,獲取字母進行索引搜索單詞, 那就for循環添加 按鈕吧, 這是封裝的view, 在這里記錄一下, 可以直接復制代碼效果圖
:
.h 里有個block 可以回調點擊的是哪個單詞這里床的是字符串
#import
@interfaceTKYKeyboardView :UIView
@property(nonatomic,copy)void(^seachLetterStrbBlock)(NSString* letterStr);
@end
.m中具體思路是創建三個view, 第一行是一個view 第二行是一個view, 第三行字母也是一個view,然后for循環 添加字母按鈕
#import "TKYKeyboardView.h"
#import "UIView+Extension.h"
@interface TKYKeyboardView()
@property (nonatomic, strong)NSMutableArray *arrM;
@property? (nonatomic, strong)UIButton *button;
@end
@implementationTKYKeyboardView
