iPhone用户默认设置

我已将NSString值存储在NSUserDefaults中，但不知道如何将该存储值检索到另一个字符串中。

使用此选项访问

NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];

        yourString= [standardUserDefaults objectForKey:@"key"];

使用此选项访问

NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];

        yourString= [standardUserDefaults objectForKey:@"key"];

设定值

NSString* pin = @"somthig";
[[NSUserDefaults standardUserDefaults] setObject:pin forKey:@"TokenPin"];

NSString* pin;
pin = (NSString*)[[NSUserDefaults standardUserDefaults] objectForKey:@"TokenPin"];

获得价值

NSString* pin = @"somthig";
[[NSUserDefaults standardUserDefaults] setObject:pin forKey:@"TokenPin"];

NSString* pin;
pin = (NSString*)[[NSUserDefaults standardUserDefaults] objectForKey:@"TokenPin"];

设定值

NSString* pin = @"somthig";
[[NSUserDefaults standardUserDefaults] setObject:pin forKey:@"TokenPin"];

NSString* pin;
pin = (NSString*)[[NSUserDefaults standardUserDefaults] objectForKey:@"TokenPin"];

获得价值

NSString* pin = @"somthig";
[[NSUserDefaults standardUserDefaults] setObject:pin forKey:@"TokenPin"];

NSString* pin;
pin = (NSString*)[[NSUserDefaults standardUserDefaults] objectForKey:@"TokenPin"];

Kashif看一看教程，看一看数据检索部分…如下所示

Retrieving

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

// getting an NSString
NSString *myString = [prefs stringForKey:@"keyToLookupString"];

// getting an NSInteger
NSInteger myInt = [prefs integerForKey:@"integerKey"];

// getting an Float
float myFloat = [prefs floatForKey:@"floatKey"];

您可以使用如下所示

NSString *retrieveString =[[NSUserDefaults standardUserDefaults] objectForKey: @"key"];

您可以使用如下所示

NSString *retrieveString =[[NSUserDefaults standardUserDefaults] objectForKey: @"key"];
