plistの読み出し書き出し

plistで読み出しNSDictionaryで格納する。

NSDictionaryは非常に便利。

NSMutableDictionary *appDict;

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);

NSString *path = [paths objectAtIndex:0];

path = [path stringByAppendingPathComponent:@"app.plist"];

if ([[NSFileManagerdefaultManager] fileExistsAtPath:path]) {

    NSMutableDictionary *appDict = [NSDictionarydictionaryWithContentsOfFile:path];

    //何かの処理

    [appDict writeToFile:path atomically:YES];

} else {

}
