[問題] iphone上將檔案寫入的問題
我有一段code如下
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
if (paths.count > 0) {
NSString *loginInfoFilePath =
[[paths objectAtIndex:0] stringByAppendingFormat:@"loginInfo.plist"];
NSFileManager *fileManager = [NSFileManager defaultManager];
// if loginInfo.plist do not exists:
if (![fileManager fileExistsAtPath:loginInfoFilePath]) {
NSDictionary *loginInfoDictionary = [[NSDictionary alloc]
initWithObjectsAndKeys:@"", nicknameKey, @"", passwordKey, nil];
[loginInfoDictionary writeToFile:loginInfoFilePath atomically:YES];
[loginInfoDictionary release];
}
// here loginInfo.plist should always exists
if ([fileManager fileExistsAtPath:loginInfoFilePath]) {
// do something here.
}
上面總共有3個if
我在simulator上測試，app第一次launch時3個if都有跑到
可是換在device上測試的時候，一樣是第一次launch
卻唯獨第3個if跑不進去
問題可能出在writeToFile沒有成功
可是我還不確定
而且另我納悶的是為什麼simulator可以，device卻會有不一樣的結果QQ
是哪邊出問題了嗎~
