摇一摇根据城市位置推荐酒店

摇一摇根据城市位置推荐酒店客户端

1、实现摇一摇并震动需要导入头文件。#import

[self becomeFirstResponder];[UIApplication sharedApplication].applicationSupportsShakeToEdit = YES;

4、关键代码
在移动的时候将手机震动，并将view显示出来，并请求接口，将酒店显示出来，点击进入到酒店详情界面。

#pragma mark - UIResponder-(void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event{AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);self.bgView.alpha = 0;self.bgView.hidden = YES;[UIView animateWithDuration:1.0 animations:^{[self getRandomHotel];self.bgView.alpha = 1;self.bgView.hidden = NO;self.hotelImage.image = [UIImage imageNamed:@"My_about"];self.label.text = @"您已经成功摇到一个酒店，不喜欢？换个姿势再来一次";[self.label sizeToFit];self.hotelImage.contentMode = UIViewContentModeScaleAspectFill;self.hotelImage.autoresizingMask = UIViewAutoresizingFlexibleHeight;self.hotelImage.clipsToBounds = YES;//动态设置uilabel的高度self.hotelLabel.numberOfLines = 0;self.hotelLabel.lineBreakMode = NSLineBreakByWordWrapping;} completion:^(BOOL finished) {}];NSLog(@"摇一摇开始");return ;}-(void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event{NSLog(@"取消摇一摇");return ;}-(void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event{if (motion ==UIEventSubtypeMotionShake ){NSLog(@"摇一摇结束");}return ;}

效果图

随机推荐酒店后台实现

实现思路：

1、接收客户端传来的参数：城市名称、App key；

2、根据城市名称模糊搜索出酒店数据；

3、根据搜索出的酒店数据数组长度，生成1个随机数，随机数范围[1,数组长度]；

4、利用封装好的Responese将数据返给客户端
