简单的电影介绍应用

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

FirstViewController.m文件

#import "FirstViewController.h"
#import "SecondViewController.h"
@interface FirstViewController ()

@end

@implementation FirstViewController
@synthesize label5,label6,firstTextView;

    //创建标签

    label1.text = @"电影简介";
    label1.font = [UIFont systemFontOfSize:50];
    label1.textAlignment = NSTextAlignmentCenter;

    UILabel *label2 = [[UILabel alloc]initWithFrame:CGRectMake(5, 130, 200, 100)];

    [self.view addSubview:label4];

    //初始化movie
    NSNumber *num = [NSNumber numberWithInteger:123456];
    movie = [[Movie alloc]initWithTitle:@"疯狂动物城" andMoney:num andDescrip:@"非常好看，无法形容，烂透了！！！！！！！"];

    label6.font = [UIFont systemFontOfSize:30];
    label6.textAlignment = NSTextAlignmentLeft;
    //设置显示行数
    //label6.numberOfLines = 0;//0是不限制

    firstTextView = [[UITextView alloc]initWithFrame:CGRectMake(140, 255, 220, 350)];

    firstTextView.text = movie.descrip;
    firstTextView.font = [UIFont systemFontOfSize:25];
    [firstTextView setBackgroundColor:[UIColor grayColor]];
    //让firstTextView不可修改
    firstTextView.editable = NO;

    [self.view addSubview:label5];
    [self.view addSubview:label6];
    [self.view addSubview:firstTextView];


    //创建编辑按钮
    UIButton *btn = [[UIButton alloc]initWithFrame:CGRectMake(130, 600, 150, 90)];
    [btn setTitle:@"编辑" forState:UIControlStateNormal];
    [btn setTitleColor:[UIColor orangeColor] forState:UIControlStateNormal];
