对plist文件进行读写
//获取路径对象 NSArray *pathArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *path = [pathArray objectAtIndex:0]; //获取文件的完整路径 NSString *filePatch = [path stringByAppendingPathComponent:@"column.plist"]; NSLog(@"%@",filePatch); //写入数据到plist文件 NSMutableDictionary *dic1 = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"小小虎",@"name",@"5",@"age",@"boy",@"sex",nil]; NSMutableDictionary *dic2 = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"小小兮",@"name",@"6",@"age",@"girl",@"sex",nil]; //将上面2个小字典保存到大字典里面 NSMutableDictionary *dataDic = [NSMutableDictionary dictionary]; [dataDic setObject:dic1 forKey:@"一年级"]; [dataDic setObject:dic2 forKey:@"二年级"]; //写入plist里面 [dataDic writeToFile:filePatch atomically:YES]; //读取plist文件的内容 NSMutableDictionary *dataDictionary = [[NSMutableDictionary alloc] initWithContentsOfFile:filePatch]; NSLog(@"---plist一开始保存时候的内容---%@",dataDictionary);
对pilst文件进行修改
//修改字典里面的内容,先按照结构取到你想修改内容的小字典 NSMutableDictionary *dd = [dataDictionary objectForKey:@"一年级"]; [dd setObject:@"我改名字了哦" forKey:@"name"]; [dd setObject:@"我添加的新内容" forKey:@"content"]; [dd removeObjectForKey:@"age"]; //修改成功以后，将这个小字典重新添加到大字典里面 [dataDictionary setObject:dd forKey:@"一年级"]; [dataDictionary writeToFile:filePatch atomically:YES]; NSLog(@"---plist做过操作之后的字典里面内容---%@",dataDictionary);
删除
//清除plist文件，可以根据我上面讲的方式进去本地查看plist文件是否被清除
NSFileManager *fileMger = [NSFileManager defaultManager];
NSString *xiaoXiPath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0]stringByAppendingPathComponent:@"xiaoxi.plist"];
//如果文件路径存在的话
BOOL bRet = [fileMger fileExistsAtPath:xiaoXiPath];
if (bRet) {
NSError *err;
[fileMger removeItemAtPath:xiaoXiPath error:&err];
}
以上这篇iOS 对plist文件进行读写,增删改查的实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
