RGBAで指定した色のUIImageを生成

-(UIImage*)get255ColorRectImage:(float)r g:(float)g b:(float)b alpha:(float)alpha size:(CGSize)_size{
    UIGraphicsBeginImageContext(_size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextSetRGBFillColor(context, r/255.0,g/255.0,b/255.0,alpha/255.0);
    CGContextFillRect(context, CGRectMake(0.0,0.0,_size.width,_size.height));
    UIImage *screenImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return screenImage;
}

UIImage*redImage=[self get255ColorRectImage:255.0 g:0.0 b:0.0 alpha:255.0 size:CGSizeMake(100, 100)];

UITabBarの背景を削除する

-(void)removeTabBarBackground:(UITabBar*)_tab{
    for(UIView*t in _tab.subviews){
        NSString*s=NSStringFromClass([t class]);
        if ([s isEqualToString:@"UITabBarButton"] || t==_tab) {
            continue;
        }
        [t removeFromSuperview];
        break;
    }
}

[self removeTabBarBackground:_mytab];

NSURLをNSStringへ変換

NSString*t=[webView.request.URL absoluteString];

UITouchからCGPoint取得

-(CGPoint)getCGPointByUITouch:(UITouch*)t{
    return [t locationInView:self.view.superview];
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    NSArray*t=[touches allObjects];
    CGPoint tp1=[self getCGPointByUITouch:[t objectAtIndex:0]];
}

NSDateからNSString生成

-(NSString*)getStringByDate:(NSDate*)_date{
    NSDateFormatter*df=[[NSDateFormatter alloc] init];
    NSCalendar*cal=[[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
    [df setCalendar:cal];
    [df setDateFormat:@"yyyy/MM/dd HH:mm:ss"];
    NSString* str=[df stringFromDate:_date];
    [cal release];
    [df release];
    return str;
}
