我正在將UITextField的圖層作爲子圖層添加到實際上是UIImageView的現有圖層中。我在圖像視圖上應用透視旋轉並且工作正常。但是UITextField不會激活。它的beginFirstResponder消息不顯示鍵盤。點擊它不起作用,它在用戶交互中保持不活動狀態。我也嘗試爲文本框的圖層設置zPosition,以便它位於imageview圖層上方,並且它是zPosition。UITextField作爲子圖層
rightband = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"right-band.png"]];
rightband.layer.frame = CGRectMake(623.5, 310.5, 624, 210);
rightband.layer.zPosition = 40.0f;
usernameField = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 260, 26)];
usernameField.clearButtonMode = UITextFieldViewModeWhileEditing;
usernameField.keyboardType = UIKeyboardTypeDefault;
usernameField.autocapitalizationType = UITextAutocapitalizationTypeNone;
usernameField.borderStyle = UITextBorderStyleNone;
usernameField.backgroundColor = [UIColor clearColor];
usernameField.font = [UIFont fontWithName:@"HelveticaNeue" size:17];
usernameField.textColor = UIColorFromRGB(0x303030);
usernameField.textAlignment = UITextAlignmentLeft;
usernameField.placeholder = @"Username";
usernameField.autocorrectionType = UITextAutocorrectionTypeNo;
usernameField.returnKeyType = UIReturnKeyNext;
usernameField.delegate = self;
usernameField.layer.anchorPoint = CGPointMake(1.0f, 0.5f);
usernameField.layer.zPosition = 100.0f;
usernameField.layer.frame = CGRectMake(10, 10, 260, 26);
[rightband.layer addSublayer:usernameField.layer];
沒錯。我想了很多。但是,然後我創建右帶(透視旋轉)的動畫。直到它是子圖層時,應用子圖層轉換纔會起作用。 – Bourne
