UIImage*picture1 = [[UIImageimageNamed:@"fuwu-1"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

UIImage*picture2 = [[UIImageimageNamed:@"pingjia-1"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

NSArray*images =@[picture1,picture2,picture3];

UISegmentedControl*segment= [[UISegmentedControlalloc]initWithItems:images];

这样就可以正常显示图片啦

UIImage*picture3 = [[UIImageimageNamed:@"wenti-1"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
