Question

made an object, MyTextBoxCreator. i need to make lots of text boxes dynamically. i want to be able to pass in a frame to the method.

.h file
-(UITextField *) standardTextField: (CGRect *) myRec;


.m file
-(UITextField *) standardTextField: (CGRect *) myRect
{
    UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 30)];

    UITextField *myTextField = [[UITextField alloc] initWithFrame:myRect];
    myTextField.font = [UIFont fontWithName:textFieldFont size:textFieldFontSize];
    myTextField.borderStyle = UITextBorderStyleLine;
    myTextField.backgroundColor = [UIColor whiteColor];
    myTextField.textColor = [UIColor textFieldTextColor];
    myTextField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    myTextField.layer.borderColor = [[UIColor textfieldBorderColor]CGColor];
    myTextField.layer.borderWidth = 1.0f;
    myTextField.leftView = paddingView;
    myTextField.leftViewMode = UITextFieldViewModeAlways;
    myTextField.clearButtonMode = UITextFieldViewModeWhileEditing;

    return myTextField;
}

when i try to create the textfield with myRect for the CGRect, i get the error:

Sending 'CGRect *' (aka 'struct CGRect *') to parameter of incompatible type 'CGRect" (aka "struct CGRect')

i don’t understand whats wrong with passing in the CGRect…

Answer 1

Don’t pass a pointer to the CGRect, just pass the structure itself.

-(UITextField *) standardTextField: (CGRect) myRect;

Note that it’s a structure, not an actual object.

Though, if you need to pass in a pointer to the struct, you can dereference it:

...
-(UITextField *) standardTextField: (CGRect *) myRect {
CGRect rectStruct = *myRect;
...
UITextField *myTextField = [[UITextField alloc] initWithFrame:rectStruct];
...
