1,Incorrect decrement of the reference count of an object that is not owned at this point by the caller
这种问题一般就是变量申请了内存并初始化了,但没有使用此变量,接着将此变量又重新赋值。如下:
NSString *imageString = [[NSString alloc] init];
imageString = @"HResout";
2,Receiver in message expression is a garbage value
UIColor* tempCol;
if (level==4) {
tempCol= [[UIColor alloc] initWithRed:0.39f green:0.82f blue:0.32f alpha:1.0f];
}else if (level==5) {
tempCol= [[UIColor alloc] initWithRed:0.61f green:0.68f blue:0.83f alpha:1.0f];
}else if (level==6) {
tempCol= [[UIColor alloc] initWithRed:0.90f green:0.68f blue:0.99f alpha:1.0f];
}else if (level==7) {
tempCol= [[UIColor alloc] initWithRed:0.68f green:0.97f blue:0.99f alpha:1.0f];
}
return [tempCol autorelease];
被赋值的是个要回收的变量
