Custom UISwitch for iphone

You can modify the UISwitch title and customize the UISwitch using either of the following methods:

1. Use category extension UISwitch.

As follows:

The following is a UISwitch. h file:

 

# Import <UIKit/UIKit. h>

 

@ Interface UISwitch (tagged)

+ (UISwitch *) switchWithLeftText: (NSString *) tag1 andRight: (NSString *) tag2;

@ Property (nonatomic, readonly) UILabel * label1;

@ Property (nonatomic, readonly) UILabel * label2;

@ End

 

UISwitch. m file:

# Import UISwitch-Extended.h"

 

# Define TAG_OFFSET 900

 

@ Implementation UISwitch (tagged)

-(Void) spelunkAndTag: (UIView *) aView withCount :( int *) count

{

For (UIView * subview in [aView subviews])

{

If ([subview isKindOfClass: [UILabel class])

{

* Count + = 1;

[Subview setTag TAG_OFFSET + * count)];

}

Else

[Self spelunkAndTag: subview withCount: count];

}

}

 

-(UILabel *) label1

{

Return (UILabel *) [self viewWithTag: TAG_OFFSET + 1];

}

 

-(UILabel *) label2

{

Return (UILabel *) [self viewWithTag: TAG_OFFSET + 2];

}

 

+ (UISwitch *) switchWithLeftText: (NSString *) tag1 andRight: (NSString *) tag2

{

UISwitch * switchView = [[UISwitch alloc] initWithFrame: CGRectZero];

 

Int labelCount = 0;

[SwitchView spelunkAndTag: switchView withCount: & labelCount];

 

If (labelCount = 2)

{

[SwitchView. label1 setText: tag1];

[SwitchView. label2 setText: tag2];

}

 

Return [switchView autorelease];

}

 

@ End

 

2. There is another method, which is relatively simple but difficult to understand.

 

 

 

UISwitch * isFooOrBar = [[UISwitch alloc] init];

 

 

 

(UILabel *) [[[[[isFooOrBar subviews] lastObject] subviews] objectAtIndex: 2] subviews] objectAtIndex: 0]). text = @ "Foo ";

(UILabel *) [[[[[isFooOrBar subviews] lastObject] subviews] objectAtIndex: 2] subviews] objectAtIndex: 1]). text = @ "Bar ";
