Birincisi:

//Tabbar Background icin
tabbar.backgroundColor = [UIColor clearColor];
CGRect frame = CGRectMake(0, 0, 320, 62);
UIView *v = [[UIView alloc] initWithFrame:frame];
UIImage *i = [UIImage imageNamed:@"tabbar.png"];
UIColor *c = [[UIColor alloc] initWithPatternImage:i];

// UIColor *c = [UIColor blueColor];
v.backgroundColor = c;
[c release];
[[self tabbar] insertSubview:v atIndex:0];

UIView Katman Yapısı

Sırası ile

1- Window

2- TabbarView veya UIViewController olabilir.

3- Navigation Controller

4- View, Componentler

Xcode

//DateFormatter

NSTimeInterval secondsPerDay = 24 * 60 * 60;

NSTimeInterval secondsPerDay2 = 2* 24 * 60 * 60;

NSTimeInterval secondsPerDay3 = 4* 24 * 60 * 60;

//Gun

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

[dateFormatter setDateFormat:@"dd"];

//Ay

NSDateFormatter *dateFormatter1 = [[NSDateFormatter alloc] init];

[dateFormatter1 setDateFormat:@"MMMM"];

Background image vermek icin gerekli kodu viewDidLoad kismina yaziniz ve background imagenizi  uygumalaminiza atiniz.

[code language="cpp"]

- (void)viewDidLoad

{

[super viewDidLoad];

//Background

self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"yellow.jpg"]];
