Basic use method

The theme switch uses the Name to identify, a theme can correspond to multiple json configuration files. The framework is mainly used for theme configuration with json files. You need to add the json configuration file locally, or manually register the json file.

Manually register the json file using the following method:

+ (void)addTheme:(NSString *)themeName forPath:(NSString *)path;

Json file format is as follows:

{
    "colors": {
        "c1": "b2770f",
        "c2": "b2770f",
        "c3": "aaaaaa",
        "c4": "b2770f",
        "c5": "b2770f",
   },
    "fonts": {
        "f1": "8",
        "f2": "9",
        "f3": "10",
        "f4": "14",
        "f5": "16",
    },
    "coordinators": {
        "Offset1": "{0,10}",
        "Offset2": "{0,30}",
        "Offset3": "{-15,10}",
        "Offset4": "{-20,50}"
    }
}

Json file colors,fonts, coordinators for the fixed wording, you can add other Key. The corresponding identity can be the same, but the same key will be overwritten. It is recommended to maintain with a set of standards.

Colors format:

RGB / ARGB / RRGGBB / AARRGGBB

Fonts format:

"16"

Coordinators format:

{1,2} / {1,2,3,4} / {1,2,3,4,5,6}

How to use LNTheme

NSObject+LNTheme.hThis class contains the set-up methods that are supported.

@property (strong, nonatomic)NSMutableDictionary *themePickers;
- (void)updateFont;
- (void)updateTheme;
- (void)ln_customFontAction:(id(^)(void))block;
- (void)ln_customThemeAction:(id(^)(void))block;
- (void)setThemePicker:(NSObject *)object selector:(NSString *)sel picker:(LNThemePicker *)picker;
@end

@interface UIColor (LNTheme)
+ (UIColor *)colorWithHexString:(NSString *)hexString;
@end
...

Color multi-theme settings

//UIView 
[self.view ln_backgroundColor:@"c8"];

//UILabel 
[self.label ln_textColor:@"c5"];

//UITextField 
[self.textField ln_textColor:@"c8"];

//UISwitch 
[self.testSwitch ln_onTintColor:@"c8"];

Font multi-theme settings

//UINavigationBar & titleTextAttributes
[navBar ln_titleTextAttributesColorType:@"c9" font:@"f10"];

Picture multi-theme settings

//UIImageView
[self.imageview ln_imageNamed:@"cm2_chat_bg"];

//UIButton
[self.button ln_backgroundImageNamed:@"cm2_edit_cmt_bg" forState:UIControlStateHighlighted];

Picture custom colors can be used by the method provided by this extension of UIImage + Tint.h.

Topic related attributes

Get the relevant dependency values using the methods contained in LNTheme.h, and get them through Key.

+ (UIFont *)fontForType:(NSString *)type;
+ (UIImage *)imageNamed:(NSString *)name;
+ (UIColor *)colorForType:(NSString *)type;
+ (id)otherForType:(NSString *)type;
+ (CGSize)sizeForType:(NSString *)type;
+ (CGRect)rectForType:(NSString *)type;
+ (CGPoint)pointForType:(NSString *)type;
+ (CGVector)vectorForType:(NSString *)type;
+ (UIEdgeInsets)edgeInsetsForType:(NSString *)type;
+ (CGAffineTransform)affineTransformForType:(NSString *)type;

Other

If you do not include the set options, you can manually refresh the control-related properties, using the methods contained in NSObject + LNTheme.h:

- (void)ln_customThemeAction:(id(^)(void))block;

For example, when the topic is switched, the UITableView is refreshed

__weak typeof(self) wself= self;
[self ln_customThemeAction:^id {
    [wself.tableView reloadData];
    return nil;
}];
