我的应用程序在启动后立即崩溃。我认为这与我在这个init函数中定义两个大数组有关：
- (AppIndex*)init {
if (self = [super init]) {
float rgba[] = { 1.0f, 1.0f, 1.0f, 1.0f };
range = [Text make:@"50 mi" font:[UIFont fontWithName:@"GillSans" size:30] color:rgba width:1000];
[range centerOnX:420 Y:10 width:121 height:40];
mode = [Text make:@"Relevant" font:[UIFont fontWithName:@"GillSans" size:30] color:rgba width:1000];
[mode centerOnX:100 Y:10 width:121 height:40];
NSString* wow = @"WOW";
Vertex vertices[] = {

- (void)vboWithVertices:(Vertex[])vertices count:(GLuint)countV indices:(GLushort[])indices count:(GLuint)countI {
glGenBuffers(1, &vertexBuffer);
glBindBuffer(GL_ARRAY_BUFFER, vertexBuffer);
NSLog(@"%u", sizeof(Vertex));
glBufferData(GL_ARRAY_BUFFER, countV * sizeof(Vertex), vertices, GL_STATIC_DRAW);
glGenBuffers(1, &indexBuffer);

}
这有几个方面。 range和mode是正在加载的两个纹理。 icons和background也是如此。那些巨大的数组也会在最后复制到VBO。
这可以达到我可以在我的应用中添加内容的某个时刻。现在，如果我向同一个函数添加一行，它将崩溃。就像这样：
NSString* wow = @"Wow";
如果我在函数外部添加数组（可能是因为某些内存已被释放），它不会崩溃。
我的应用会因EXC_BAD_ACCESS而崩溃。如果我注释掉两个大型数组，我的应用程序工作，所以我认为这是一个内存问题。但即便使用的内存也不多。当应用程序崩溃Xcode表示它运行＆lt; 1ms，内存高6.4MB，低6.4MB。
无论如何，这些数组只是占位符，我会更有条理。这有补救措施吗？有人可以解释为什么会崩溃吗？

数组数据全部在堆栈AFAICS上......不要把它放在堆栈上
