1、 从Resource 中 读取文件内容

1NSBundle *bundel=[NSBundle mainBundle];

2NSString *filePath=[bundel pathForResource:@"txtfile" ofType:@""];

3NSLog(@"filePath:%@",filePath);

4NSString *fileContent=[NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];

5NSLog(@"fileContent:%@",fileContent);

2、读取图片

01NSBundle *bundel=[NSBundle mainBundle];

02NSString *imgPath=[bundel pathForResource:@"home" ofType:@"png"];

03UIImage *image=[UIImage imageWithContentsOfFile:imgPath];

04UIImageView *imageView =[[UIImageView alloc]initWithImage:image];

05[self.view addSubview:imageView];

06    

07//简便方法

08UIImageView *imageView2=[[UIImageView alloc]initWithImage:[UIImage imageNamed:@"list"]];

09//move position

10imageView2.center=CGPointMake(40, 15);

11[self.view addSubview:imageView2];

3、NSFileManager 打印目录信息

1NSFileManager *fm=[NSFileManager defaultManager];

2NSString *path=[[NSBundle mainBundle]bundlePath];

3NSArray *info=[fm contentsOfDirectoryAtPath:path error:nil];

4NSLog(@"list:%@",info);
