Adjusting frame of UIView. The easier way.

	// UIView category

	- (void)adjustFrame:(void(^)(CGRect *frame))block {
	CGRect frame = self.frame;
	block(&frame);
	self.frame = frame;
	}

Great debugging tool when you have a lot of views ;)

	@implementation UIColor (Random)


	+ (instancetype)randomColor {
	return [self colorWithRed:(arc4random() % 255) / 255.f
	green:(arc4random() % 255) / 255.f
	blue:(arc4random() % 255) / 255.f
	alpha:1];

Tricertops / Validate NSString as number

Created February 2, 2013 08:52

Three options how to validate `NSString` instance to contain numeric value.

	NSString *theString; // You have a string.



	/// Option 1: floatValue
	if ([theString floatValue] != 0 \|\| [theString hasPrefix:@"0.0"] \|\| [theString isEqualToString:@"0"]) {
	// theString should be number
	}
