搖一搖根據城市位置推薦酒店

###搖一搖根據城市位置推薦酒店客戶端###

一、實現搖一搖並震動須要導入頭文件。#import <AudioToolbox/AudioToolbox.h>

二、當前城市定位，能夠看我以前的文字快速定位

三、讓vc支持搖一搖。

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

四、關鍵代碼 在移動的時候將手機震動，並將view顯示出來，並請求接口，將酒店顯示出來，點擊進入到酒店詳情界面。

#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 = @"您已經成功搖到一個酒店，不喜歡？換個姿式再來一次";
[self.label sizeToFit];
self.hotelImage.contentMode = UIViewContentModeScaleAspectFill;
self.hotelImage.autoresizingMask = UIViewAutoresizingFlexibleHeight;
self.hotelImage.clipsToBounds = YES;
//動態設置uilabel的高度
self.hotelLabel.numberOfLines = 0;
self.hotelLabel.lineBreakMode = NSLineBreakByWordWrapping;
} completion:^(BOOL finished) {

}];
NSLog(@"搖一搖開始");
return ;
}

-(void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event{
NSLog(@"取消搖一搖");
return ;
}

-(void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event{
if (motion ==UIEventSubtypeMotionShake ){
NSLog(@"搖一搖結束");
}
return ;
}

效果圖

###隨機推薦酒店後臺實現###

實現思路：

一、接收客戶端傳來的參數：城市名稱、App key；

二、根據城市名稱模糊搜索出酒店數據；

三、根據搜索出的酒店數據數組長度，生成1個隨機數，隨機數範圍[1,數組長度]；

四、利用封裝好的Responese將數據返給客戶端
