The iOS SDK supports progress bar functionality, allowing developers to pass in custom functions (blocks) to monitor upload progress events and implement custom business logic.

Sample Code

The following code demonstrates how to use a progress bar during the upload process.

​
TOSCredential *credential = [[TOSCredential alloc] initWithAccessKey:@"accesskey" secretKey:@"secretkey" securityToken:@"securityToken"];​
TOSEndpoint *tosEndpoint = [[TOSEndpoint alloc] initWithURLString:@"endpoint" withRegion:@"region"];​
TOSClientConfiguration *config = [[TOSClientConfiguration alloc] initWithEndpoint:tosEndpoint credential:credential];​
TOSClient *client = [[TOSClient alloc] initWithConfiguration:config];​
​
TOSPutObjectInput *put = [TOSPutObjectInput new];​
put.tosBucket = @"bucket-name";​
put.tosKey = @"object-name";​
put.tosContent = your_data; // NSData​
​
​
put.tosUploadProgress = ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend) {​
    NSLog(@"%lld, %lld, %lld", bytesSent, totalBytesSent, totalBytesExpectedToSend);​
};​
​
TOSTask *task = [client putObject:put];​
[task continueWithBlock:^id(TOSTask *task) {​
    if (!task.error) {​
        NSLog(@"Put object success.");​
        TOSPutObjectOutput *output = task.result;​
    } else {​
        NSLog(@"Put object failed, error: %@" ,task.error);​
    }​
    return nil;​
}];​
