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"]];
