@end Did The Same. Can you please explain me a bit more. What to do in cell for row at index path

答案 0 :(得分：0)
如果它是一个BOOL，你可以保存它，如果你想要多个选项，只需更改为NSInteger：
//设置值
- (void)saveMyValue:(BOOL)myValue {
[[NSUserDefaults standardUserDefaults] setInteger:[NSNumber numberWithBool:myValue ].integerValue forKey:@"myActionKeyHere"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
//获取值
- (NSInteger)myValue {
NSInteger myValue = [[NSUserDefaults standardUserDefaults] integerForKey:@"myActionKeyHere"];
return myValue ;
}

@Hauzin告诉你NSUserDefaults的方式。
顺便说一句，我对你的案子有另一个想法。
首先，按钮选择状态的类型是BOOL类型。 所以我们必须将BOOL值设置为NSNumber值。 （[NSNumber numberWithBool：xxx]）
然后，如果你有一个UITableView并且UITableView需要多个按钮的选择状态，你可以将按钮选择状态保存为NSArray。 然后你可以编写一个带有NSArray类型参数的方法来创建新的UITableView。 （例如： - （void）setupXXXtableViewWithButtonStatus：（NSArray *）buttonStatusArray;）
答案 2 :(得分：0)
如果要在NSUserDefault中保存按钮状态，可以使用以下代码。
NSUserDefaults *udefaults=[NSUserDefaults standardUserDefaults];
if (btn.selected) {
[udefaults setBool:YES forKey:@"isSelected"];
}else{
[udefaults setBool:NO forKey:@"isSelected"];
}
要获得可以使用的按钮状态。
NSUserDefaults *udefaults=[NSUserDefaults standardUserDefaults];
BOOL isButtonSelected = [udefaults boolForKey:@"isSelected"];
另外，请勿忘记在此synchronize上致电udefaults。
[udefaults synchronize];
希望，这有帮助。
