A UILabel that displays a given value in a given format string.
Instantiate the label with a format string and a default value. For example, [[DRFormattedLabel alloc] initWithFormat:@"Current tempurature: %@", defaultValue: @"--"]
Set the value by using the generated setValue method. When the temperature changes, for example [label setValue:@32]
And finally, to clear the current value of the label, and go back to displaying the default label, you can call [label clear]
For reference, here is the full public interface:
- (instancetype)initWithFrame:(CGRect)frame format:(NSString*)format defaultValue:(NSString*)defaultValue;
- (instancetype)initWithFormat:(NSString*)format defaultValue:(NSString*)defaultValue;
@property (nonatomic, strong) NSString* format;
@property (nonatomic, strong) NSString* defaultValue;
@property (nonatomic, strong) id value;
-(void)clear;
