NSUserDefaults简单使用

字典存入本地

NSUserDefaults *userdef = [NSUserDefaults standardUserDefaults];

[userdef setObject:xxx forKey:xxx];

[userdef synchronize]; 每次更新数据

拿到所存内容

NSUserDefaults *userdf = [NSUserDefaults standardUserDefaults];

[userdf objectForKey:_model.uid]

清除

NSString*appDomain = [[NSBundle mainBundle] bundleIdentifier];

[[NSUserDefaults standardUserDefaults] removePersistentDomainForName:appDomain];
