UIColor *color = [UIColor colorWithPatternImage:image];
UIView *view = [[UIView alloc] initWithFrame:<#CGRect#>];
[view setBackGroundColor:color];

UIImage *image = [UIImage imageNamed:@"<#Your Image#>"];
UIView *view = [[UIView alloc] initWithFrame:<#CGRect#>];
[view layer].contents = (__bridge id)image.CGImage;
// 显示的范围
[view layer].contentsCenter = CGRectMake(0.25, 0.25, 0.5, 0.5);
