1.图片的不同状态显示
解决方法一:
| 本地路径 | 网络路径 | 状态 |
|---|---|---|
| 1 | 0 | 点击上传 |
| 1 | 1 | 已上传 |
| 0 | 1 | 已上传 |
| 0 | 0 | 点击拍照 |
if([image hasPrefix:@"http"] ) {
//只要有网络路径或者本地图片已上传 -- 就代表已上传
[cell.uploadButton setTitle:@"已上传" forState:UIControlStateNormal];
cell.UploadStausImageView.image = [UIImage imageNamed:@"uploadedMany"];
}else if ([path hasPrefix:@"/"] ) { //本地有 但是没有网络路径 --代表 等待上传
[cell.uploadButton setTitle:@"点击上传" forState:UIControlStateNormal];
cell.UploadStausImageView.image = [UIImage imageNamed:@"waitingUpload"];
}else {
[cell.uploadButton setTitle:@"点击拍照" forState:UIControlStateNormal];
cell.UploadStausImageView.image = [UIImage imageNamed:@"clickToTakePhoto"];
}
这只是刚入坑而已.这样做存在一个问题:本地路径,网络路径同时存在的话有两种可能
- 1.已上传
- 2.点击上传(更新图片的情况)
于是又有了以下思路:利用标记的思想,来判断本地图片是否已经上传过.
| 标记本地图片 | 状态 |
|---|---|
| 0 | 点击上传 |
| 1 | 已上传 |
if([image hasPrefix:@"http"] ) { //只要有网络路径或者本地图片已上传 -- 就代表已上传
//既有网络路径又有本地路径 有两种情况
if ([[[NSUserDefaults standardUserDefaults]objectForKey:path] isEqualToString:@"0"] ) {
[cell.uploadButton setTitle:@"点击上传" forState:UIControlStateNormal];
cell.UploadStausImageView.image = [UIImage imageNamed:@"waitingUpload"];
}else {
[cell.uploadButton setTitle:@"已上传" forState:UIControlStateNormal];
cell.UploadStausImageView.image = [UIImage imageNamed:@"uploadedMany"];
}
}else if ([path hasPrefix:@"/"] || [[[NSUserDefaults standardUserDefaults]objectForKey:path] isEqualToString:@"0"]) { //本地有 但是没有网络路径 --代表 等待上传
[cell.uploadButton setTitle:@"点击上传" forState:UIControlStateNormal];
cell.UploadStausImageView.image = [UIImage imageNamed:@"waitingUpload"];
}else {
[cell.uploadButton setTitle:@"点击拍照" forState:UIControlStateNormal];
cell.UploadStausImageView.image = [UIImage imageNamed:@"clickToTakePhoto"];
}
2.上传单张图片
公司利用的是一个第三方(七牛),自己也封装了一个上传单张图片的类
- (void)uploadWithFile:(NSString *)file withProgress:(QNUpProgressHandler)progress success:(void(^)(NSString*url))success failure:(void(^)())failure {
UIImage *getImage = [UIImage imageWithContentsOfFile:file];
QNUploadOption *option = [[QNUplLBHTTPRequestoadOption alloc] initWithMime:nil progressHandler:progress params:nil checkCrc:NO cancellationSignal:nil];
//先获取token
[LBHTTPRequest postImage:[LBHTTPRequest getUserId] token:[LBHTTPRequest getUserToken] userType:@"1" fileExt:@"png" SuccessBlock:^(BOOL isSuccess, NSDictionary *resultDic) {
if (isSuccess) {
NSString * token = resultDic[@"uploadToken"];
QNUploadManager *upManager = [[QNUploadManager alloc] init];
NSData *data;
if (UIImagePNGRepresentation(getImage) == nil){
data = UIImageJPEGRepresentation(getImage, 1);
} else {
data = UIImagePNGRepresentation(getImage);
}
[upManager putData:data key:resultDic[@"fileKey"] token:token
complete: ^(QNResponseInfo *info, NSString *key, NSDictionary *resp) {
[SVProgressHUD dismiss];
// isLoadLogo = NO;
if([resp[@"result"] intValue] == 200){
[LBUploadManager sharedInstance].imageUrl = resp[@"fileUrl"];
success([LBUploadManager sharedInstance].imageUrl);
}
} option:option];
}
}];
}
3.上传多张图片
七牛第三方并没有提供多张图片上传的方法,但是无所谓.
//上传多张图片
- (void)uploadImagesWithFileArray:(NSMutableArray *)fileArray progress:(void(^)(CGFloat))progress success:(void(^)(NSString *))success failure:(void(^)())failure {
//判断网络状态
AFNetworkReachabilityManager *netStatus = [AFNetworkReachabilityManager sharedManager];
[netStatus startMonitoring];
[netStatus setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
if (status == AFNetworkReachabilityStatusNotReachable) {//无网络连接
[SVProgressHUD showWithStatus:@"当前无网络连接"];
}
if (status == AFNetworkReachabilityStatusReachableViaWWAN) { //手机自带网络
//提示用户是否继续进行上传图片
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"友情提示" message:@"当前使用的手机流量,您是否继续?" delegate:[LBUploadManager sharedInstance] cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
[alert show];
}
if (status == AFNetworkReachabilityStatusReachableViaWiFi) { //wifi
//1.获取所有的图片
NSMutableArray *imageArray = [[LBUploadManager sharedInstance]getImageArrayWithFileArray:fileArray];
dispatch_queue_t queue = dispatch_get_global_queue(0, 0);
dispatch_async(queue, ^{
for (int i = 0; i < imageArray.count; i ++ ) {
dispatch_async(queue, ^{ //上传头像
[[LBUploadManager sharedInstance]uploadWithFile:imageArray[i] withProgress:^(NSString *key, float percent) {
progress(percent);
} success:^(NSString *url) {
success(url);
//获取studentId
NSString *key = [[LBUploadManager sharedInstance].fileArray[i] allKeys].lastObject;
[LBHTTPRequest PostUpdataStudentImageWithStudentId:key withStudentImage:url andSuccessBlock:^(BOOL isSuccess, NSDictionary *resultDic) {
if (isSuccess) {
[[NSNotificationCenter defaultCenter]postNotificationName:@"refresh" object:nil];
[[NSNotificationCenter defaultCenter]postNotificationName:@"updataStudentData" object:nil];
}
[[NSUserDefaults standardUserDefaults]setObject:@"1" forKey:imageArray[i]];
[[LBUploadManager sharedInstance].fileArray removeObject:imageArray[i]];
}];
} failure:^{
}];
});
}
});
}
if (status == AFNetworkReachabilityStatusUnknown) { //未知网络
}
}];
}
