NSBundle

ios中去访问应用自身的资源文件可以使用NSBundle。

1.把需要访问的资源文件拖到工程中，选择复制



2、调用方式

NSBundle* bundle=[NSBundle mainBundle];
NSLog(@"%@",[bundle resourcePath]);

NSString* path= [bundle pathForResource:@"t" ofType:@"txt"] ;

NSLog(@"t.txt路径 %@",path);
NSString* txt=[NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
NSLog(@"内容%@",txt);



打印如下
