Change Position and Image of UIImageView

Hi,
I got following code to change my ImageView

[UiImageView setContentMode:UIViewContentModeRedraw];
[UiImageView setBounds:CGRectMake( 0, 0, 50, 50)];

I now hot to change it with last two numbers, but there is no difference if first two numbers change.
How can I change the position of it like

UiImageView.left = 100
UiImageView.top = 50
(Thats what it looks like in .net)

And my second problem is:

How can I switch different pictures in my UiImageView???

Thanks to all

Mac Mini, Mac OS X (10.5.4)

Hi,

to set the postion of a view within it's superview use the frame property.

To show a different image just change the image property.

To change the position of a UIView (or subclass):


CGRect frame = myView.frame;
frame.origin.x = 12.0;
frame.origin.y = 3.0;
// optionally change the size as well
// frame.size.width = 100.0;
// frame.size.height = 250.0;
myView.frame = frame;

OR


myView.frame = CGRectMake(12.0, 3.0, 100.0, 250.0);

Unfortunately you CANNOT do something like this:


myView.frame.size.x = 100.0;

because ".frame" is not really accessing the variable directly; it is sending a message (calling a method) behind the scenes. Read about properties in the Objective-C 2.0 reference. However ".size.x" is a normal C struct access.
