Using a NSString to set a color for a label
ios, nsstring, objective-c, selector, uicolor
Solution
Use this method
-(UIColor *)giveColorfromStringColor:(NSString *)colorname
{
SEL labelColor = NSSelectorFromString(colorname);
UIColor *color = [UIColor performSelector:labelColor];
return color;
}
Call as
[view setBackgroundColor:[self giveColorfromStringColor:@"redColor"]];
The method name takes `colorname` as input and gives the corresponding UIColor
Thus in your case the call will be
self.textLabel.textColor = [self giveColorfromStringColor:@"redColor"];
Problem
I want to create a method and use a string value "redColor" to set the UIColor for a label. tableColorName is the NSString "redColor" and I tried to apply a selector to create the UIColor and apply it to my textLabel. Thanks ``` -(void) changeLabelColor { SEL labelColor = NSSelectorFromString([NSString stringWithFormat:[@"%@", tableColorName]]); UIColor *color = [[UIColor class] performSelector:labelColor]; self.textLabel.textColor = color; } ```
