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
