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

Sample Code

The following code demonstrates how to use a progress bar during the download 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];​
​
TOSGetObjectInput *get = [TOSGetObjectInput new];​
get.tosBucket = @"bucket-name";​
get.tosKey = @"object-name";​
​
​
get.tosDownloadProgress = ^(int64_t bytesWritten, int64_t totalBytesWritten, int64_t totalBytesExpectedToWrite) {​
    NSLog(@"%lld, %lld, %lld", bytesWritten, totalBytesWritten, totalBytesExpectedToWrite);​
};​
​
TOSTask *task = [client getObject:get];​
[task continueWithBlock:^id(TOSTask *task) {​
    if (!task.error) {​
        NSLog(@"Get object success.");​
        TOSGetObjectOutput *output = task.result;​
        NSData *date = output.tosContent;​
    } else {​
        NSLog(@"Get object failed, error: %@" ,task.error);​
    }​
    return nil;​
}];​
