I have tried hiding a segmented controller just like a button or label can be hidden in XCode. It's intended to be hidden/shown when touching a parent segmented controller above. This Code would work with Buttons or Labels:

mySegmContr.hidden = YES;

But i开发者_JS百科t just won't work for segmented controllers. Can you help me out?


I figured out that you can use a simple UIView in which you put the things you want to hide. The UIView can then be hidden with

myView.hidden = YES;

still I found no way to hide a segmented control directly.


If you create a property for the segment controller you can do more stuff with it like changing it's location, resizing it and want you want hiding it.

In your .h file do this

UISegmentedControl *mySegment;
@property (nonatomic, retain) UISegmentedControl *mySegment;

-(void) createMySegment;

In your .m file do this

@synthesize mySegment;


- (void) createMySegment     {  
if ([self mySegment] == nil) {      
    NSArray *buttons = [NSArray arrayWithObjects:@"One", @"Two", @"Three", nil];
    UISegmentedControl *segName = [[UISegmentedControl alloc] buttons];  
    [self setMySegment:segName];
    [segName release]; 
    segName.frame = CGRectMake(110, 62, 120, 25);           
    segName.segmentedControlStyle = UISegmentedControlStyleBar;
    segName.momentary = NO;
    segName.selectedSegmentIndex = 0;
    [segName addTarget:self
                action:@selector(pickMethod:)
      forControlEvents:UIControlEventValueChanged];
    [self.view addSubview:segName];             
} 

}

NOTE: With "setMySegment" above make sure you use a capital first letter which is M in "mySegment". Then when you want to hide it use this. Don't for get to dealloc mySegment.

[[self mySegment] setHidden:YES];
