iOS应用管理(字典转模型)

1. 新建appViewModel

1.1声明需要的属性

//NSString一般用copy来修饰

@property(nonatomic,copy)NSString *name;

@property(nonatomic,copy)NSString *icon;

//字典转模型的方法

- (id)initWithDict:(NSDictionary *)dict;

1.2字典转模型

- (id)initWithDict:(NSDictionary *)dict{

if(self = [super init]){

self.name = dict[@"name"];

self.icon = dict[@"icon"];

}

return self;

}

2.ViewController

#import "ViewController.h"

#import "appViewModel.h"

@interface ViewController ()

@property(nonatomic,strong)NSArray *apps;

@end

@implementation ViewController

- (NSArray *)apps{

if(_apps == nil){

//1-获取plist文件的路径

NSString *path = [[NSBundle mainBundle]pathForResource:@"app.plist" ofType:nil];

//2-读取文件

NSArray *dictArray = [NSArray arrayWithContentsOfFile:path];

//3-字典转模型

NSMutableArray *tempArr = [NSMutableArray array];

for(NSDictionary *dic in dictArray){

appViewModel *appModel = [[appViewModel alloc]initWithDict:dic];

[tempArr addObject:appModel];

}

_apps = tempArr;

}

return _apps;

}

- (void)viewDidLoad{

[super viewDidLoad];

//1-设置frame的相关属性

CGFloat appViewW = 100;

CGFloat appViewH = 120;

CGFloat spaceX = 20;

CGFloat spaceY = 30;

CGFloat topMargin = 30;

CGFloat leftmargin = (self.view.frame.size.width - 3 * appViewW - 2 * spaceX) * 0.5;

//2-创建格子

for( int i = 0; i < self.apps.count; i ++){

//2.1-创建一个格子视图

UIView *appView = [[UIView alloc]init];

int row = i / 3;//行号

int col = i % 3;//列号

CGFloat appViewX = leftmargin + (appViewW + spaceX) * col;

CGFloat appViewY = topMargin + (appViewH + spaceY) * row;

//2.2设置frame

appView.frame = CGRectMake(appViewX, appViewY, appViewW, appViewH);

//2.3添加

[self.view addSubview:appView];

appViewModel *appViewModel = self.apps[i];

//2.4添加图片

UIImageView *head = [[UIImageView alloc]init];

CGFloat headW = 60;

CGFloat headX = (appViewW - headW) *0.5;

CGFloat headY = 0;

CGFloat headH = 60;

head.image = [UIImage imageNamed:  appViewModel.icon ];

head.frame = CGRectMake(headX, headY, headW, headH);

[appView addSubview:head];

//        head.backgroundColor = [UIColor blueColor];

//        2.5添加label

//         2.5.1 创建一个文本标签

UILabel *nameLabel = [[UILabel alloc]init];

CGFloat nameLabelX = 0;

CGFloat nameLabelY = headY + headH;

CGFloat nameLabelW = appViewW;

CGFloat nameLabelH = 30;

nameLabel.frame = CGRectMake(nameLabelX, nameLabelY, nameLabelW, nameLabelH);

[appView addSubview:nameLabel];

//        nameLabel.backgroundColor = [UIColor grayColor];

nameLabel.text = appViewModel.name;

//       2.5.2设置文字大小

nameLabel.font = [UIFont systemFontOfSize:13];

//        2.5.3设置文字居中

nameLabel.textAlignment = NSTextAlignmentCenter;

//        2.6添加button

UIButton *downLoadBtn = [[UIButton alloc]init];

CGFloat downLoadBtnX = 10;

CGFloat downLoadBtnY = nameLabelY + nameLabelH + 10;

CGFloat downLoadBtnW = appViewW - downLoadBtnX *2;

CGFloat downLoadBtnH = 30;

downLoadBtn.frame = CGRectMake(downLoadBtnX, downLoadBtnY, downLoadBtnW, downLoadBtnH);

[appView addSubview:downLoadBtn];

//        downLoadBtn.backgroundColor = [UIColor greenColor];//设置背景色

[downLoadBtn setTitle:@"下载" forState:UIControlStateNormal];//设置文字

[downLoadBtn setBackgroundImage:[UIImage imageNamed:@"buttongreen"] forState:UIControlStateNormal];

[downLoadBtn setBackgroundImage: [UIImage imageNamed:@"buttongreen_highlighted"] forState:UIControlStateHighlighted];

//        downLoadBtn.

//        按钮内部至少有两个控件,一个label,一个imageView,

downLoadBtn.titleLabel.font = [UIFont systemFontOfSize:14];

}
