如何使用NSFileHandle打开文本文件
|
我正在尝试打开一个小的文本文件，以测试该文件上的某些NSFileHandle函数。但是，如果您能告诉我我所缺少的内容，那真是太好了。
//。H
@interface MainViewController : UIViewController <FlipsideViewControllerDelegate> {
NSFileHandle *nCode;
}
@property (nonatomic, retain) IBOutlet NSFileHandle *nCode;
- (IBAction)showInfo:(id)sender;
//check for code
- (void)fetchCode:(id)sender; //this function is attached to a button in the .nib
@end
- (void)fetchCode:(id)sender{
nCode = [NSFileHandle fileHandleForReadingAtPath:@\"nCode01.txt\"];
if (nCode == nil) {
NSLog (@\"Open of nCode for reading failed\\n\");
return;
}
[nCode closeFile];
}
没有找到相关结果

：NSString *path = [[NSBundle mainBundle] pathForResource:@\"nCode01\" ofType:@\"txt\"]; nCode = [NSFileHandle fileHandleForReadingAtPath:path];
