简单的电影介绍应用

小编自己编写不免会有疏忽，如有错误请多多指正

首先创建工程，这里我们采用纯手写代码方式，新建俩个UIViewController的子类文件，分别是：FirstViewController、SecondViewControlle。之后声明一个类文件movie用来存放电影的属性。

注：下面空间的坐标适合iPhone6s plus，如果想要适用于其他的手机需要进行适配，我会在以后的文章中进行补充。

然后进行编写，下面是代码：

movie.h文件

#import <Foundation/Foundation.h>@interface Movie : NSObject{    NSString *title;//电影名    NSNumber *money;//票房    NSString *descrip;//简介}@property(nonatomic,retain) NSString *title;@property(nonatomic,retain) NSNumber *money;@property(nonatomic,retain) NSString *descrip;-(id)initWithTitle:(NSString*)_t andMoney:(NSNumber*)_m andDescrip:(NSString*)_d;@end

movie.m文件

#import "movie.h"@implementation Movie@synthesize title,money,descrip;//初始化方法-(id)initWithTitle:(NSString*)_t andMoney:(NSNumber*)_m andDescrip:(NSString*)_d{    if (self = [super init]) {        self.title = _t;        self.money = _m;        self.descrip = _d;    }    return self;}@end

FirstViewController.h文件：

#import <UIKit/UIKit.h>#import "movie.h"@interface FirstViewController : UIViewController{    Movie * movie;    UILabel *label5;//用来显示电影名称    UILabel *label6;//电影票房    UITextView *firstTextView;//电影简介}@property (nonatomic,retain) UILabel *label5;@property (nonatomic,retain) UILabel *label6;@property (nonatomic,retain) UITextView *firstTextView;@end
