#import <Foundation/Foundation.h>

});
return sharedIns;
}
- (instancetype)init{

- (instancetype)_init {

if (self) {
_kAVCBackgroundColor = [UIColor colorWithHexString:@"1e222d"];
_kAVCThemeColor = [UIColor colorWithHexString:@"00c1de"];
}
return self;
}
@end
使用方式
self.view.backgroundColor = [AlivcUIConfig shared].kAVCBackgroundColor;
