iOS开发代码：从文本文件中读取内容到字符串里

核心提示：NSError *error;NSString *textFileContents = [NSStringstringWithContentsOfFile:[[NSBundle mainBundle]pathForResource:@”myTextFile”ofType:@”txt”]encoding:NSUTF8St

NSError *error;

NSString *textFileContents = [NSString

stringWithContentsOfFile:[[NSBundle mainBundle]

pathForResource:@”myTextFile”

ofType:@”txt”]

encoding:NSUTF8StringEncoding

error: & error];

// If there are no results, something went wrong

if (textFileContents == nil) {

// an error occurred

NSLog(@”Error reading text file. %@”, [error localizedFailureReason]);

}

NSArray *lines = [textFileContents componentsSeparatedByString:@” ”];

NSLog(@”Number of lines in the file:%d”, [lines count] );
