iPhone 輸入面板(textfield)的作法

如果不打算從IB裡面去建立textfield,這邊有custom的作法
1. 首先在.h裡先宣告
UITextField *usrname;
@property (nonatomic, retain, readonly) UITextField usrname;
在.m裡面
@synthesize usrname;

2. 然後自己加上

- (UITextField *)usrname

{

  if (usrname == nil)

  {

    CGRect frame = CGRectMake(x, y, width, height);

    usrname = [[UITextField alloc] initWithFrame:frame];

    usrname.borderStyle = UITextBorderStyleNone;

    usrname.textColor = [UIColor blackColor];

    usrname.font = [UIFont systemFontOfSize:17.0];

    usrname.placeholder = @"user name";

    usrname.backgroundColor = [UIColor whiteColor];

    usrname.autocorrectionType = UITextAutocorrectionTypeNo; 

    usrname.autocapitalizationType = UITextAutocapitalizationTypeNone;

    usrname.keyboardType = UIKeyboardTypeDefault;

    usrname.returnKeyType = UIReturnKeyDone;

    usrname.clearButtonMode = UITextFieldViewModeWhileEditing;

    //we can remove it later for recycled cells

    usrname.tag = kViewTag;

    //when the keyboard's "Done" button is pressed

    usrname.delegate = self;

    // Add an accessibility label that describes what the text field is for.

    usrname setAccessibilityLabel:NSLocalizedString(@"username", @"")];

  }

  return usrname;

}

喔～最後要在dealloc中release
[usrname release];
