Dear Members, Scholars. As it may seem obvious I am not armed with Objective C knowledge. Levering on other more simple computer languages I am trying to set a dynamic name for a list of buttons generated by a simple loop (as the following code suggest).
Simply putting it, I would like to have several UIButtons generated dynamically (within a loop) naming them dynamically, as well as other related functions.
button1,button2,button3 etc..
After googling and searching Stackoverlow, I haven't arrived to a clear simple answer, thus my question.
- (void)viewDidLoad {
// This is not Dynamic, Obviously
UIButton *button0 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button0 setTitle:@"Button0" forState:UIControlStateNormal];
button0.tag = 0;
button0.frame = CGRectMake(0.0, 0.0, 100.0, 100.0);
button0.center = CGPointMake(160.0,50.0);
[self.view addSubview:button0];
// I can duplication the lines manually in terms of copy them over and over, changing the name and other related functions, but it seems wrong. (I actually know its bad Karma)
// The question at hand:
// I would like to generate that within a loop
// (The following code is wrong)
float startPointY = 150.0;
//
for (int buttonsLoop = 1;buttonsLoop < 11;buttonsLoop++){
NSString *tempButtonName = [NSString stringWithFormat:@"button%i",buttonsLoop];
UIButton tempButtonName = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[tempButtonName setTitle:tempButtonName forState:UIControlStateNormal];
tempButtonName.tag = tempButtonName;
tempButtonName.frame = CGRectMake(0.0, 0.0, 100.0, 100.0);
tempButtonName.center = CGPointMake(160.0,50.0+startPointY);
[self.view addSubview:tempButtonName];
startPointY += 100;
}
}
