图片交换的实现，分为页面数据交换和服务器数据交换
服务器数据交换：获取所有的服务器信息，根据页面图片位置的变化来进服务器信息的位置的改变
@property (nonatomic,retain) NSMutableDictionary *informationDic; //存储所有从服务器得到的信息
#pragma mark informationDic懒加载
- (NSMutableDictionary *)informationDic {
if (!_informationDic) {
_informationDic = [NSMutableDictionary dictionary];
}
return _informationDic;
}
[self.informationDic setObject:dic[@"imgid"] forKey:dic[@"photolocindex"]]; //获取服务器中图片的图片位置和imageID
#pragma mark 调换字典中的两个位置
NSNumber *beginObject = [self.informationDic objectForKey:[NSNumber numberWithInteger:beginLoc]];
NSNumber *endObject = [self.informationDic objectForKey:[NSNumber numberWithInteger:endLoc]];
[self.informationDic setObject:endObject forKey:[NSNumber numberWithInteger:beginLoc]];
[self.informationDic setObject:beginObject forKey:[NSNumber numberWithInteger:endLoc]];
#pragma mark 图片调换位置接口
- (void)exchangePicture
{
#pragma mark 固定数据
NSString *t = [BaseViewController millisecondsDifferential];
NSString *ImgId = [NSString string];
NSString *PhotoInd = [NSString string];
#pragma mark 变化部分
NSArray *keys = [self.informationDic allKeys];
for (NSNumber *key in keys) {
ImgId = self.informationDic[key];
PhotoInd = [NSString stringWithFormat:@"%@",key];
NSString *jiami = [BaseViewController md5:[NSString stringWithFormat:@"t=%@&ImgID=%@&PhotoIndex=%@&UserId=%ld",t,ImgId,PhotoInd,_userid]];
NSString *jiami1 = [BaseViewController Keymd5:jiami];
NSString *auth = [BaseViewController md5:jiami1];
NSString *strUrl = [NSString stringWithFormat:@"%@%@%@&%@%@&%@%@&%@%@&%@%ld",KTHttp,kExchangPicture,t,@"auth=",auth,@"ImgID=",ImgId,@"PhotoIndex=",PhotoInd,@"UserId=",_userid];
[NetManager requestDataWithUrlString:strUrl finished:^(id responseObj) {
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseObj options:NSJSONReadingMutableContainers error:nil];
if (!_letfVC) {
_letfVC = [[LeftVC alloc] init];
}
[_letfVC personHomepage];
NSLog(@"%@",dic);
} failed:^(NSString *errorMsg) {
//NSLog(@"%@",errorMsg);
}];
}
}
页面图片的交换，两种方式：
- 1> 第一种直接交换两个图片的image，而本身imageview不变，这样的话，所有的tag值都可以写死，只需要改变imageDic（图片位置和图片一一对应的数据），根据index来对图片进行重新赋值，刷新talbeView
- 2> 直接改变所有imageView的frame，也就是所有的imageView都可以随意移动，对整个局面来说没有太大的影响，用其tag值和本身的image来决定一切。
- (void)exchangePhoto:(NSInteger)beginLoc andEndloc:(NSInteger)endLoc; //代理方法，对外传输两个交换的imageView的坐标，只需根据坐标将两个坐标对应的imageId进行交换即可
@property (nonatomic,retain) NSMutableDictionary *imageDic; //存储申请下来的图片
#pragma mark 懒加载imageDic
- (NSMutableDictionary *)imageDic {
if (!_imageDic) {
_imageDic = [NSMutableDictionary dictionary];
}
return _imageDic;
}
#pragma mark 根据接口获取所有的image，将对应的坐标和image存到imageDic中
- (void)imagesWithImageUrlDic:(NSMutableDictionary *)imageUrlDic {
UIImageView *imageView = [[UIImageView alloc] init];
NSArray *keys = [imageUrlDic allKeys];
if (keys.count) {
for (NSNumber *key in keys) {
NSInteger index = key.integerValue;
if (index == 1) {
[imageView sd_setImageWithURL:[NSURL URLWithString:imageUrlDic[key]] placeholderImage:nil completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
[self.imageDic setObject:image forKey:key];
}];
} else if (index==2) {
[imageView sd_setImageWithURL:[NSURL URLWithString:imageUrlDic[key]] placeholderImage:nil completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
[self.imageDic setObject:image forKey:key];

[imageView sd_setImageWithURL:[NSURL URLWithString:imageUrlDic[key]] placeholderImage:nil completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {

[imageView sd_setImageWithURL:[NSURL URLWithString:imageUrlDic[key]] placeholderImage:nil completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
