UITableViewCell 和 UISwitches - iPhone SDK [英] UITableViewCell and UISwitches - iPhone SDK

问题描述

我正在尝试为 UITableView 中的每个单元格保存 UISwitch 的状态.有没有办法做到这一点?我正在考虑使用 NSUserDefault 但我不太确定使用给定名称保存值，然后在创建单元格时检索该状态.任何建议都会很好！

谢谢，

凯文

解决方案

你可以试试下面的示例代码；

<预><代码>NSMutableDictionary *dictionay = [[NSMutableDictionary alloc] init];[dictionay setObject:@"1" forKey:@"firstcell"];[dictionay setObject:@"2" forKey:@"secondcell"];..........[[NSUserDefaults standardUserDefaults] setObject:dictionay forKey:@"dictionay"];//检索值；NSMutableDictionary *dictionay = (NSMutableDictionay*)[[NSUserDefaults standardUserDefaults] valueForKey:@"dictionay"];if([[dictionay valueForKey:@"firstcell"] isEqualToString:@"1"])switch1.on = 是;别的switch1.on = NO;........

希望能帮到你.

I am trying to save the states of an UISwitch for each cell in my UITableView. Is there a way to do this? I was thinking of using the NSUserDefault but I'm not too sure about saving the values with a given name and then retrieving that state when the cells are created. Any suggestions would be nice!

Thanks,

Kevin

解决方案

you can try with following sample code;

NSMutableDictionary *dictionay = [[NSMutableDictionary alloc] init];
[dictionay setObject:@"1" forKey:@"firstcell"];
[dictionay setObject:@"2" forKey:@"secondcell"];
.....
.....
[[NSUserDefaults standardUserDefaults] setObject:dictionay forKey:@"dictionay"];

// retrieve values;
NSMutableDictionary *dictionay = (NSMutableDictionay*)[[NSUserDefaults standardUserDefaults] valueForKey:@"dictionay"];
if([[dictionay valueForKey:@"firstcell"] isEqualToString:@"1"])
    switch1.on = YES;
else
    switch1.on = NO;
....
....

I hope, it will help you.
