Objective-c – How to programmatically change UIColor of view

iphoneobjective cuicolor

Okay, this question comes through a friend so it might be lost in translation…

Basically we need to change the color on a View. It appears to be stored in NSString format, but using a NSString to set the UIColor doesn't seem to do anything. In other words, if NSString color holds the value "redColor" then:

self.view.backgroundColor = color;  //does nothing

Disclaimer: we are Objective-C/iPhone newbies.

Try

self.view.backgroundColor = [UIColor redColor];

You can also give RGB values like

self.view.backgroundColor = [UIColor colorWithRed:200/255.0 green:0/255.0 blue:67/255.0 alpha:1.0];

All the Best.
