读取txt文件，然后改写为plist文件
-(void)convertTxtToPlist:(NSString *)fileName
{
//读取文本文件
NSString *txtPath = [[NSBundle mainBundle] pathForResource:fileName ofType:@"txt"];
NSString *txtContent = [NSString stringWithContentsOfFile:txtPath encoding:NSUTF8StringEncoding error:nil];
//进行每行的处理
NSArray *txtArry = [txtContent componentsSeparatedByString:@"\r\n"];
NSMutableArray *plistArry = [NSMutableArray array];
for (NSString *question in txtArry) {
if (isNSString(question)) {
NSRange range = [question rangeOfString:@","];
NSString *area_id = [question substringToIndex:range.location];
NSString *name = [question substringFromIndex:range.location+1];
name = [name stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys:area_id,@"area_id",name,@"name", nil];
[plistArry addObject:dic];
}
}
//写到plist文件中
NSArray *stringPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDirectory = [stringPath objectAtIndex:0];
NSString *path = [docDirectory stringByAppendingPathComponent:@"city.plist"];
NSLog(@"%@",path);
[plistArry writeToFile:path atomically:YES];
}
判断字符串为空
bool isNSString(id string)
{
if (![string isKindOfClass:[NSString class]])
{
return NO;
}
NSString *str=(NSString *)string;
if ([str isKindOfClass:[NSNull class]])
{
return NO;
}
if (str==nil||[str isEqualToString:@""])
{
return NO;
}
else
{
return YES;
}
}
