很多地方我们都使用16进制颜色，但iPhone使用的是UIColor对象，不直接支持16进制颜色，为此，需要我们手动将16进制颜色转换为UIColor。

- (UIColor *)getColor:(NSString *)hexColor

{

unsigned int red,green,blue;

NSRange range;

range.length = 2;

range.location = 0;

[[NSScanner scannerWithString:[hexColor substringWithRange:range]] scanHexInt:&red];

range.location = 2;

[[NSScanner scannerWithString:[hexColor substringWithRange:range]] scanHexInt:&green];

range.location = 4;

[[NSScanner scannerWithString:[hexColor substringWithRange:range]] scanHexInt:&blue];

return [UIColor colorWithRed:(float)(red/255.0f) green:(float)(green / 255.0f) blue:(float)(blue / 255.0f) alpha:1.0f];

}

[self.view setBackgroundColor:[self getColor:@"FF0000"]];
