ios应用数据存储方式(偏好设置)

//1.获取NSUserDefaults对象
NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];

//2保存数据
[defaults setObject:@"liyong" forKey:@"name"];
[defaults setInteger:30 forKey:@"age"];
[defaults setDouble:1.80f forKey:@"height"];
[defaults setObject:@"man" forKey:@"gender"];

//3.强制让数据立刻保存
[defaults synchronize];

//1.获取NSUserDefaults对象
NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];
//2.读取保存的数据
NSString *name=[defaults objectForKey:@"name"];
NSString *gender=[defaults objectForKey:@"gender"];
NSInteger age=[defaults integerForKey:@"age"];
double height=[defaults doubleForKey:@"height"];
