創(chuàng)建一個自定義的View
.h文件
#import <UIKit/UIKit.h>

@property (nonatomic, copy) SelectCionsTypeBlock??????? selectCionsBlock;

在ViewController里面調(diào)用
SelectCionsTypeView * typeView=[[SelectCionsTypeView alloc]init];
? ? ? ? [typeView show];
? ? ? ? typeView.cionsList=self.dataList;
? ? ? ? typeView.selectCionsBlock = ^(CoinsTypeModel *model) {
? ? ? ? ? ? self.coinsTypeModel=model;
? ? ? ? ? ? _tagIndex = 0;
? ? ? ? ? ? self.cionsTypeTF.text=self.coinsTypeModel.cn_name
? ? ? ? };
想要自定義彈出視圖的小伙伴們可以參考一下拟糕，非常簡單判呕，點擊彈出自定義的tableView，可以自定義Model進行賦值送滞，
