Converting a first character of string to upper case (case changes): In this example, we are going to show you how to change the first character of the given string into uppercase. Create a simple "window based" application and place a button on it(connection with file Owner is req.). Button is required to give a action otherwise it will not show anything.
Syntax of NSString CapitalizedString:
NSString *firstCapChar = [[String substringToIndex:1] capitalizedString];
NSString *cappedString = [String stringByReplacingCharactersInRange:NSMakeRange(0,1) withString:firstCapChar];
Note: capitalizedString is used to convert first character of string into upper case.
Now let's explore the code:
capitalizefirstcharAppDelegate.h
#import <UIKit/UIKit.h>
@interface capitalizefirstcharAppDelegate :
NSObject <UIApplicationDelegate> {
UIWindow *window;
IBOutlet UIButton *button;
NSString *string;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UIButton *button;
@property (nonatomic, retain) NSString *string;
-(IBAction)captlizedString:(id)sender;
@end
capitalizefirstcharAppDelegate.m
#import "capitalizefirstcharAppDelegate.h"
@implementation capitalizefirstcharAppDelegate
@synthesize window, button, string;
-(IBAction)captlizedString:(id)sender;
{
NSString *string1 = @"rose";
NSString *firstCapChar =
[[string1 substringToIndex:1] capitalizedString];
NSString *cappedString =
[string1 stringByReplacingCharactersInRange
:NSMakeRange(0,1) withString:firstCapChar];
NSLog(cappedString);
}
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Override point for customization after application launch
[window makeKeyAndVisible];
}
- (void)dealloc {
[window release];
[button release];
[super dealloc];
}
@end
