Make TextField and Label dynamically in scroll View based on arrayValue and count
Make Label :- using this we can make label dynamically based on array value
categoryAry=[[NSArray alloc]initWithObjects:@"Object1",@"Object2",@"Object3",@"Object4",@"Object5",@"Object6",@"Object7",@"Object8",@"Object9",@"Object10", nil];
-(void)mekeAllLabelDynamicly
{
CGFloat startX= 50.0f;
CGFloat startY= 150.0f;
for (int i = 0 ; i< [categoryAry count]; i++)
{
UILabel *label=[[UILabel alloc] init];
label.text = [categoryAry objectAtIndex:i];
label.tag=i;
label.textColor = [UIColor whiteColor];
label.backgroundColor=[UIColor clearColor];
CGRect frame=CGRectMake(startX, startY+(31+10)*i, 100, 31);
[label setFrame:frame];
[self.view addSubview:label];
}
}
Make Label+TextField and get value of textField
