三行代码实现UIPickerView(地区选择为例)

城市有我奋斗的青春.jpg

使用方法:

// 点击事件调用以下三行
-(void)showPickerView{
    Dz_PickerArea * area = [[Dz_PickerArea alloc]init];
    [area setDelegate:self];
    [area showPickerView];
}
// 实现代理方法
-(void)pickerArea:(Dz_PickerArea *)pickerArea province:(NSString *)orivubce city:(NSString *)city area:(NSString *)area{
    NSLog(@"省份-城市-区县:%@-%@-%@",orivubce,city,area);
    NSString * title = [NSString stringWithFormat:@"%@ %@ %@",orivubce,city,area];
    self.label.text = title;
}
