本文主要是介绍测试SDWebImage淡入淡出效果在UITableView中的重用显示问题，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

测试SDWebImage淡入淡出效果在UITableView中的重用显示问题

这个是在上一篇教程的基础上所添加的测试环节！

效果图（从效果图中看是没有任何重用问题的）：

源码：

ImageCell.h 与 ImageCell.m

#import "ImageCell.h"@implementation ImageCell- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];if (self) {_bigImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 250, 400)];[self addSubview:_bigImageView];}return self;
}- (void)setSelected:(BOOL)selected animated:(BOOL)animated {[super setSelected:selected animated:animated];// Configure the view for the selected state
}@end
