以編程方式創建多個視圖

您好，我想問一下如何以編程方式創建多個視圖並將它們顯示在屏幕上，我試過這個，但有些東西缺失。以編程方式創建多個視圖

int x,y; 

x= 0; 
y=50; 

for (int i=0; i<4; i++) 
{ 
    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(x, y, 300, 100)]; 

view.backgroundColor = [UIColor redColor]; 


[self.view addSubview: view]; 

    y+=40; 
}

你有這個代碼的哪個方法？ –

你使用哪種方法？我試圖在swift中創建多個UIViews，但我認爲這樣做會覆蓋它並從superview中刪除前一個。 – TheeBen

int x,y; 
x= 0; 
y=50; 

for (int i=0; i<4; i++) 
{ 
    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(x, y, 300, 100)]; 

    view.backgroundColor = [UIColor redColor]; 
    view.layer.cornerRadius = 5.0f; 
    [self.view addSubview: view]; 
    y+=140; //y for next view should be height of previous view and margin between view 
}

謝謝，如何使它們成爲一個圓角矩形形狀？ –

嘗試設置'view.layer.cornerRadius' – Sujay

你好，我想問你如何在拖動它時更新幀大小我已經試過這段代碼： { {UITouch * touch = [touches anyObject]; CGPoint thisTouch = [touch locationInView：[touch view] .superview]; CGPoint prevTouch = [touch previousLocationInView：[touch view] .superview]; CGFloat dx = thisTouch.x - prevTouch.x; （觸摸視圖] .frame.origin.x + dx <-500） {觸摸視圖] .frame = CGRectMake（[觸摸視圖] .frame.origin.x + dx， [觸摸視圖]）。 frame.origin.y， [touch view] .frame.size.width， [touch view] .frame.size.height）; } –

int x,y; 

    x= 0; 
    y=50 
    for (int i=0; i<4; i++) 
    { 
    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(x, y, 30, 30)]; 

    view.backgroundColor = [UIColor redColor]; 
    y+=40; 

    [self.view addSubview: view];  
    }

int x,y,paddingX,widthOfView,HeightOfView; 

x= 0; 
y=50; 
paddingX = 10; 
widthOfView = 100; 
HeightOfView = 100; 

for (int i=0; i<4; i++){ 
    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(x, y, widthOfView, HeightOfView)]; 
    view.backgroundColor = [UIColor redColor]; 
    [self.view addSubview: view]; 

    y+= widthOfView + paddingX; 
}

下面的代碼可以幫助到您。
