Hi all,

I haven't been programming on the iPhone for very long, but I'm picking it up slowly by googling problems I get. Unfortunately I haven't been able to find an answer for these.

I have started a new View-based application in Xcode 3.2.2 and immediately added the following files: myUIView.m and myUIView.h, which are subclasses of UIView. In Interface Builder, I set the subclass of the default UIView to be myUIView.

I made a button in the drawRect method.

Problem one: The title of the button only appears AFTER I click the screen, why?

Problem two: I want the button to produce the modalview - is this possible?

The code is as follow:

#import "myUIView.h"
@implementation myUIView
- (void)drawRect:(CGRect)rect {
// Drawing code
    button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    button.frame = CGRectMake(0,0,100,100);
    [button setTitle:@"butty" forState:UIControlStateNormal];
    [button addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
    [self addSubview:button];
}

-(void)buttonPressed:(id)sender{
    NSLog(@"Button pressed");
    //present modal view somehow..?
}

I can't see how to post attachments, but if anyone thinks it will help I can upload the source.

Many thanks, Andy
