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 <AudioToolbox/AudioToolbox.h>

2、当前城市定位，可以看我之前的文字快速定位

3、让 vc 支持摇一摇。

[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
