[iOS objective-c] indicator 사용하기

 1. 만들 때

UIView *indicatorView;         UIActivityIndicatorView *activityIndicator;         UILabel *labelLoading;                  indicatorView = [[UIView alloc]initWithFrame:CGRectMake([UIApplication sharedApplication].keyWindow.frame.size.width/2-50, [UIApplication sharedApplication].keyWindow.frame.size.height/2-30 , 100, 100)];         indicatorView.backgroundColor = [[UIColor blackColor]colorWithAlphaComponent:0.7f];         [[UIApplication sharedApplication].keyWindow addSubview:indicatorView];         indicatorView.layer.cornerRadius = 10;         [[indicatorView layer] setBorderWidth:1.0f];         [[indicatorView layer] setBorderColor:[UIColor whiteColor].CGColor];         indicatorView.clipsToBounds = YES;         indicatorView.tag = 50;                  activityIndicator = [[UIActivityIndicatorView alloc]initWithFrame:CGRectMake(indicatorView.frame.size.width/2-15, 20, 30, 30)];         [activityIndicator setActivityIndicatorViewStyle:UIActivityIndicatorViewStyleWhiteLarge];         activityIndicator.tag = 51;         //activityIndicator.backgroundColor=[UIColor greenColor];         [indicatorView addSubview:activityIndicator];         [activityIndicator startAnimating];                  labelLoading = [[UILabel alloc]initWithFrame:CGRectMake(0, indicatorView.frame.size.height-30, indicatorView.frame.size.width, 20)];         labelLoading.text = @"Loading...";         labelLoading.textColor = [UIColor whiteColor];         labelLoading.textAlignment = NSTextAlignmentCenter;         labelLoading.font = [UIFont fontWithName:@"YanaR-Bold" size:11];         labelLoading.tag = 52;         //    [labelLoading setFont:[UIFont boldSystemFontOfSize:12.0f]];         [indicatorView addSubview:labelLoading];

2. 없앨 때

UIView *indicatorView;         UIActivityIndicatorView *activityIndicator;         UILabel *labelLoading;                  indicatorView = [[UIApplication sharedApplication].keyWindow viewWithTag:50];         activityIndicator = [indicatorView viewWithTag:51];         labelLoading = [indicatorView viewWithTag:52];         [labelLoading removeFromSuperview];         [activityIndicator removeFromSuperview];         [indicatorView removeFromSuperview];
