[상단] iOS에서 Protocol을 사용하여 클래스에 공유된 속성

UXYInjectio

UXYInjectio can use Protocol to share data that data has been autosaved.
https://github.com/uxyheaven/UXYInjectio

How To Use

creat a Protocol (inherit UXYinjectioProtocol), define the property in that Protocol

let the class support Protocol

call method sharedWithSuiteName to bind a suite name

this data is autosaved

@protocol AppConfigData <UXYinjectioProtocol>
@property (nonatomic, strong) NSString *version;
@end

@interface AppConfig : NSObject <AppConfigData>
@end

{
    AppConfig *config = [[AppConfig alloc] init];
    [config bindInjectioWithSuiteName:@"user1"];
    config.version = @"1.1";
 }

{
    AppConfig *config = [[AppConfig alloc] init];
    [config bindInjectioWithSuiteName:@"user1"];
    NSLog(@"config
");
    NSLog(@"%@
", config.version);
}

The value parameter can be only property list objects: NSData, NSString, NSNumber, NSDate, NSArray, or NSDictionary. For NSArray and NSDictionary objects, their contents must be property list objects.

@protocol PeopleData <UXYinjectioProtocol>
@property (nonatomic, assign) float height2;
@property (nonatomic, assign) int age3;
@property (nonatomic ,assign) BOOL isAlive;
@property (nonatomic, copy) NSString *name;
@end

@protocol ManData <UXYinjectioProtocol>
@property (nonatomic, strong) NSArray *nicknames;
@property (nonatomic, strong) NSDictionary *books;
@end

You can use any instance with any Protocol. The same suite name is same data.

@interface Man : NSObject <ManData, PeopleData>
@end

{
    People *people = [[People alloc] init];
    [people bindInjectioWithSuiteName:@"bill"];
    people.name = @"name";

    Man *man = [[Man alloc] init];
    [man bindInjectioWithSuiteName:@"bill"];
    NSLog(@"%@
", man.name);
}

You can use different suite name to distinguish the data.

    AppConfig *config = [[AppConfig alloc] init];
    [config bindInjectioWithSuiteName:@"user1"];
    config.version = @"1.1";

    config = [[AppConfig alloc] init];
    [config bindInjectioWithSuiteName:@"user2"];
    config.version = @"1.2";

UXYInjectio is based on NSUserDefaults. Call method immediatelySaveInjectio to synchronize.When the app enters the background it will be called automatically..
