统一管理那些使用NSUserdefaults保存的值. Blog:https://www.jianshu.com/p/681ef055f716
Create a subclass of 'NSUserDefaultsModel' and declare some properties in '.h', like this:
// .h
@property (nonatomic, copy) NSString *name;
@property (nonatomic, assign) NSInteger gender;
@property (nonatomic, assign) long age;
@property (nonatomic, assign) float floatNumber;
@property (nonatomic, assign) double doubleNumber;
@property (nonatomic, assign) BOOL isMan;
Next,you must make those properties @dynamic in the .m file,like this:
// .m
@dynamic name;
@dynamic gender;
@dynamic age;
@dynamic floatNumber;
@dynamic doubleNumber;
@dynamic isMan;
If you want to get the 'name', you just use [Subclass userDefaultsModel].name.
If you want to set the 'name' and save it, you just use [Subclass userDefaultsModel].name = @"nickname".
If you want to set some default values, you just override the method setupDefaultValues in .m file,like this:
// Setup default values
- (NSDictionary *)setupDefaultValues {
//@propertyString: @defaultValue
return @{@"name": @"lc",
@"gender": @1,
@"age": @20,
@"floatNumber": @11.1,
@"doubleNumber": @22.2,
@"isMan": @YES,
};
}
You can download this project and drag the code in the 'iOS-Objc' folder to your project. Of course，you can use Cocoapods.To install it simply add the following line to your Podfile:
pod 'NSUserDefaultsModel'
